but i'm not sure if it was removed in indigo-devel intentionally, and if it should be put back

I'm building MoveIt from source (indigo-devel branch for most packages), and getting this warnings everywhere (because octomap in included everywhere).
Is there a fix for octomap to get rid of them?
I'm using OSX 10.9, and Clang 5.1

Dear all, I am using Indigo,
coming from Groovy and Hydro, I found it difficult to understand the internals of pcl_ros and pcl_conversions packages.
My problem is the following: I have a subscription callback like this:
void RosHandler::xtionCloudCallback(const sensor_msgs::PointCloud2::ConstPtr& msg);
or, for me it's the same, like this:
void RosHandler::xtionCloudCallback(const pcl::PointCloudpcl::PointXYZRGB::ConstPtr& msg);
the first question is: is this pcl::PointCloudpcl::PointXYZRGB the same as in pcl?
if it is the same, how can I clone the data, in such a way that I can use them without bothering of what ROS is doing meanwhile (i.e., in another thread)?
What I did in Groovy (and it worked) was to manually copy the message field by field (and cloning "data"), but it does not work anymore (and, indeed, I was not sure it was safe to do that in that way).
EDIT:
when I say "it does not work" I mean that it segfault when I delete the new (cloned) cloud, so this means the ownership of the cloud was not (entirely?) mine
EDIT2:
the problem is not only I cannot delete the cloud, of course, but also that I cannot read it (it has been deleted by someone else)

Hey everyone,
I'd like to record image streams from two cameras at the same time. One is a uEye (using the uEye driver) and the other is a Asus Xtion Pro Kinect-like (using the ROS openni_camera package).
Starting data retrieval nodes for both cameras is not a problem. Displaying one of them with image_view also works. However, I cannot display or record (with rosbag) them both at the same time. The OpenNi will display just fine, but the uEye stops sending data.
I've dug into the code, and the problem seems to be that whenever the OpenNi is active (i.e., being recorded or displayed), the is_GetImageMem method within the libueye_api shared object changes behaviour: It receives a pointer and will change it to the new frame's address. The faulty behaviour results in the pointer not being changed, and indeed the image data at that address does not change either.
Has anyone seen similar behaviour? Or used a uEye camera together with a different camera?
Thanks for any help!
TL;DR: When OpenNi camera is being used, the uEye camera stops generating new frames.

I'm in the processing of standing up some regression tests, and my tests require that I can play back bag data against my node, and then monitor the output. rostest conveniently provides all the tools I need to complete this, but what's considered best practice for where the bag data should be stored? I can't have my tests failing on Jenkins because the bags are missing, but then I also don't want my repo to get unreasonably large, and I will have quite a few of these regression tests to run. Should I just run them offline?

Hi.
I need to ship to some client ans application based on ROS.
I don't want to provide my source code to this client.
So I'm planning to ship a tar.gz of the /install folder of catkin_ws or a .deb.
One starting question: does a .pyc file dependent on my system settings? or will my client have the capability to execute my node since he uses the same version of ubuntu and ros?
Supposing it makes sense to ship a .pyc and not a .py file:
The package packing process will take as input the /install folder.
The files that end-up in /install are set in the CMakeList.txt
So if I want to ship on .pyc files, I should specify them explicitly in the install section of CmakeList
But
If I checkout my svn repo in a clean environment, run catkin_make, I get an error since no pyc files have been generated yet and my Camkefile is inconsistent.
This works fine if in Cmakefile I specify to install my_file.py but this is not what I want...
So is there a way to force catkin_make to build all the python in .pyc?
Otherwise I need to run this twice with a change in Cmakelist in between...
I have lots of proprietary packages to ship, and this is just not OK.
Thanks for any insights

Hi Damein,
Are you able to run your rospy node with this process?
I am trying to do the same process for both C++ and python packages. However, it takes a lot of efforts to run a ros from install directory.
Let me know if you have some simple way of doing this?

The catkin package is giving me all kinds of problems. I have been having problems recently with Import and PYTHONPATH. After adding every catkin_pkg folder I could find to that, this latest block says that --install-layout is not recognized.

Is there an example PYTHONPATH for building ROS that I could get to stop all of the Import/package not found errors? I know that is not the way that catkin is supposed to work but seeing as how it is very temperamental now it would help.
I've also read suggestions about a groovy-gento install with a similar problem but none of those solved it here.

I am currently using Xsens MTi-28A53G35 IMU for the the motion tracking on our robot. The IMU only puts out linear and angular acceleration and orientation data. Is there an node that can transform this to linear velocity so I can use it to localize the robot and help improve the accuracy of odometry.

My IMU( Xsens MTi-28A53G35) only puts out orientation, angular velocity and linear acceleration. I want to use this data to help improve the accuracy of odom of the robot.
The Robot_localization doesn't support acceleration data from IMU so I have to transform acceleration into velocity first. I am wondering whether there are any nodes that can do this or I have write a node for it?

Hello everyone,
I am working on a robot (turtlebot) to make autonomous navigation in an unknown environment with some extra skills (objet recognition, object localization, ...).
The robot is equipped with a Hokuyo UTM-30LX and a Asus XtionPRO. On the Turtlebot there is a small laptop (Ubuntu 12.04, ROS Hydro) to get the data from the sensors (scan from the lidar and images from the camera) and to receive the cmd_velocity to move the robot.
Another computer (Ubuntu 12.04, Ros Groovy) is used to process all this data and for example to calculate the path of the robot.
For the map&localization I'm using Hector SLAM. For the navigation, I'm using Hector Navigation Stack (hector_costmap, hector_exploration_node, hector_ecploration_controller). Here is my launchfile for the navigation part:
<launch>
<node pkg="hector_costmap" type="hector_costmap" name="hector_costmap" output="screen" respawn="false">
<!-- Frame names -->
<param name="cost_map_topic" value="cost_map" />
<param name="map_frame_id" value="map" />
<param name="local_transform_frame_id" value="base_footprint" />
<param name="elevation_map_topic" value="elevation_map_local" />
<param name="grid_map_topic" value="scanmatcher_map" />
<param name="sys_msg_topic" value="syscommand" />
<param name="cloud_topic" value="openni/depth/points" />
<!-- Costmap parameters -->
<param name="use_elevation_map" value="false" />
<param name="use_grid_map" value="true" />
<param name="use_cloud_map" value="false" />
<param name="initial_free_cells_radius" value="0.3" />
<param name="update_radius" value="1.0"/>
<param name="costmap_pub_freq" value="1.0" />
</node>
<node pkg="hector_exploration_node" type="exploration_planner_node" name="hector_exploration_node" output="screen">
<rosparam file="$(find hector_exploration_node)/config/costmap.yaml" command="load" />
</node>
<node pkg="hector_exploration_controller" type="simple_exploration_controller" name="hector_exploration_controller" output="screen" respawn="true">
<remap from="/cmd_vel" to="/mobile_base/commands/velocity"/>
</node>
</launch>
And here is the costmap config file:
global_costmap:
map_type: costmap
track_unknown_space: true
unknown_cost_value: 255
obstacle_range: 2.5
raytrace_range: 3.0
footprint: [[0.15, 0.0],
[0.15, 0.15],
[0.0, 0.17],
[-0.15, 0.15],
[-0.15,0.0],
[-0.15,-0.15],
[0.0, -0.17],
[0.15, -0.15]
]
inflation_radius: 0.50
#transform_tolerance: 0.5
inscribed_radius: 0.3
circumscribed_radius: 0.32
global_frame: /map
robot_base_frame: /base_link
update_frequency: 0.5
publish_frequency: 0.1
static_map: true
rolling_window: false
cost_scaling_factor: 10.0
It seems to work well, Hector packages find frontiers, can calculate the path. The velocity command is well sent to the robot, but this latter is like a drunk robot ! It is making circles and don't follow the path.... (see Figure: https://www.dropbox.com/s/w4tuocrf1py6ffp/Screenshot%20from%202014-09-19%2016%3A54%3A22.png)
I'm sure it's because I miss something or put bad parameters. Do you have any idea ?
Thank you for your help ! :)
Edit : I make new tests and the robot still have the same behaviour: turning on itself. I noticed that the robot stops for a short moment when a new path was calculated and it still turn on itself. It's like if the robot can't be on the exact location of the path and turns to try being on the path... Is there any parameters to give it more tolerance ?
Moreover I just use the cmd_velocity generated by the hector_exploration_controller, is it enough ? I saw that there is also the hector_path_follower but it doesn't seem to work (maybe need a remap from a topic...).
Edit 2 : I still don't manage to solve this issue. Maybe I could give the exploration path generated by Hector_Exploration node to give it to a local planer ? Do you have an idea to do that ?!
Thanks for your help or suggestions !

Hello,
I have a couple of static_transform_publishers from the TF2 package running. How is it possible that a node complains about extrapolating into the future, when it tries to lookup a transformation from a random element to the static one? In my understanding, the static-transforms should be valid for all eternity, so why would you complain about timing issues?
A further explanation about my setup:
I have 2 Kinects and I am using those in my moveIt setup to create the Octomap.
As explained here, moveIt complains about extrapolation into the future while looking up a transform from my robot to the cameras.
My first solution was to write a python node, which would handle all the publishing instead of seperate static_transform_publishers from the old TF. There, I could date the transformations back in time to avoid those issues.
Now I read about the static transforms in TF2 and implemented all the camera transformations like this:
<node pkg="tf2_ros" type="static_transform_publisher" name="camera_top_base_link_1" args="0 -0.045 0 0 0 0 1 /camera_top/camera_top_link camera_top/camera_top_rgb_frame " />
Still, moveIt is complaining
[ERROR] [1411130239.665581579]: Transform error: Lookup would require extrapolation into the future. Requested time 1411130239.663295803 but the latest data is at time 1411130239.541714906, when looking up transform from frame [finger_2_link_0] to frame [camera_top/camera_top_depth_optical_frame]
[ERROR] [1411130239.997648183]: Transform cache was not updated. Self-filtering may fail
But running ``rosrun tf tf_echo /finger_2_link_0 camera_top/camera_top_depth_optical_frame` has no problems and tells me the transforms moveIt couldn't find?
Thanks in advance,
Rabe

Comment by Mani on 2014-09-19:
Have you tried reducing static_transform_publisher's publishing frequency from the current rate (1000Hz)? I would suggest that you decrease that frequency to 10Hz or even 1Hz.
Comment by Rabe on 2014-09-19:
Why is there a rate at all? My understandin was that it was "static" as in "published once"? Anyway, I can't even set the rate in the current way it is implemented, see the file here
Comment by Rabe on 2014-09-19:
I also tried various rates with the old implementation of tf, which didn't change anything either
Comment by Mani on 2014-09-19:
@Rabe Sorry, I made a mistake when reading your static_transform_publisher command.

Hi all,
I'm trying to run multiple independent Gazebo-ROS instances on the same machine so two or more remotely connected users can use it at the same time.
I've read this answer about multiple ros masters and this one about multiple Gazebo instances.I've been following them with no success.
I've tried running two ros masters on different ports and launch a gazebo empty_world.launch on each one with different group namespaces as follows:
terminal 1: Run the first ros master: roscore -p 11312
terminal 2: Run test_A.launch: Where test_A.launch is the same as gazebo_ros empty_world.launch but adding a group ns="ns_A" and changing the node names as follows:
<launch>
<!-- these are the arguments you can pass this launch file, for example paused:=true -->
<arg name="paused" default="false"/>
<arg name="use_sim_time" default="true"/>
<arg name="gui" default="true"/>
<arg name="headless" default="false"/>
<arg name="debug" default="false"/>
<arg name="verbose" default="false"/>
<arg name="world_name" default="worlds/empty.world"/> <!-- Note: the world_name is with respect to GAZEBO_RESOURCE_PATH environmental variable -->
<!-- set use_sim_time flag -->
<group if="$(arg use_sim_time)">
<param name="/use_sim_time" value="true" />
</group>
<!-- set command arguments -->
<arg unless="$(arg paused)" name="command_arg1" value=""/>
<arg if="$(arg paused)" name="command_arg1" value="-u"/>

<arg unless="$(arg debug)" name="script_type" value="gzserver"/>
<arg if="$(arg debug)" name="script_type" value="debug"/>
<group ns="ns_A">
<!-- start gazebo server-->
<node name="gazebo_A" pkg="gazebo_ros" type="gzserver" respawn="false" output="screen"
args="$(arg command_arg1) $(arg command_arg2) $(arg command_arg3) $(arg world_name)" />
<!-- start gazebo client -->
<node name="gazebo_gui_A" pkg="gazebo_ros" type="gzclient" respawn="false" output="screen"></node>
</group>
</launch>
terminal 3: Run the second ros master: roscore -p 11313
terminal 4: Run test_B.launch: Where test_B.launch is the same as gazebo_ros empty_world.launch but adding a group ns="ns_B" and changing the node names as follows:
<launch>
<!-- these are the arguments you can pass this launch file, for example paused:=true -->
<arg name="paused" default="false"/>
<arg name="use_sim_time" default="true"/>

<arg name="verbose" default="false"/>
<arg name="world_name" default="worlds/empty.world"/> <!-- Note: the world_name is with respect to GAZEBO_RESOURCE_PATH environmental variable -->
<!-- set use_sim_time flag -->
<group if="$(arg use_sim_time)">
<param name="/use_sim_time" value="true" />
</group>
<!-- set command arguments -->
<arg unless="$(arg paused)" name="command_arg1" value=""/>
<arg if="$(arg paused)" name="command_arg1" value="-u"/>
<arg unless="$(arg headless)" name="command_arg2" value=""/>
<arg if="$(arg headless)" name="command_arg2" value="-r"/>
<arg unless="$(arg verbose)" name="command_arg3" value=""/>
<arg if="$(arg verbose)" name="command_arg3" value="--verbose"/>
<arg unless="$(arg debug)" name="script_type" value="gzserver"/>
<arg if="$(arg debug)" name="script_type" value="debug"/>
<group ns="ns_B">

<!-- start gazebo client -->
<node name="gazebo_gui_B" pkg="gazebo_ros" type="gzclient" respawn="false" output="screen"></node>
</group>
</launch>
When I execute all this I get one instance of Gazebo running, in which I insert a box.
Then, when I launch the second instance (test_B.launch) I get a new Gazebo window in which I see the box inserted on the first. In other words, as I understand it, I got another client connected to the same server, even running from different ros masters. This is the exception the second instance trows:
Exception [Master.cc:50] Unable to
start server[Address already in use].
There is probably another Gazebo
process running.
¿Has anyone been able to do this? ¿Can you spot any error?
I'm using ROS Hydro on Ubuntu 12.04 LTS.
Thank you in advance for your help.

Please post your bloom log for this run (they are in ~/.bloom_logs)
Comment by ahendrix on 2014-09-19:
Have you exceeded your quota of github API requests or something?
Comment by William on 2014-09-19:
No, he probably put in his password wrong or the oauth token was revoked or something. bloom should never operate without authentication to prevent exactly this. AFAIK Github allows unlimited API requests for authenticated users.
Comment by Dave Coleman on 2014-09-19:
I changed computers this week, yes, and on the new computer Github/bloom wasn't working until I deleted the old oauth token. Now Im back on the older computer and it doesn't work. Not sure what is going on. Both computers have the same system name, also, fyi.
Comment by William on 2014-09-19:
You are getting 401 unauthorized which means the oauth token bloom has does not work. Remove the file ~/.config/bloom and try bloom again. It should prompt you to create a new oauth token. The identical computer name maybe a problem, you can edit them at https://github.com/settings/application.
Comment by kmhallen on 2014-09-21:
I had the same problem and removing the file ~/.config/bloom worked.

Hello,
I'm trying to figure out how to publish either markers or other data representing unexplored frontiers to rviz or another node. By frontier, I mean the boundary between open and unexplored space in a 2D occupancy map. I know that hector_exploration_planner does this internally and generates a single goal, after which hector_exploration_controller moves the robot to the said goal. However, I would like to play an intermediary role in the goal-determination process and then manually move the vehicle to the goal I select. Does anyone have any recommendations for ros packages that determine and publish all frontiers, or alternatively, information on how to use hector_exploration_explorer to publish this information?
Much appreciated! Please let me know if any additional information would be useful.

Hi,
I can see 2 different catkin hidden files in workspace.
.catkin_workspace and .catkin.
As far as I know ros uses .catkin file to mark folder containing packages and executable.
All setup files should be kept in folder having .catkin and .rosinstall. This is the folder which will have "lib" and "share"
directory which gets searched during rosrun or roslaunch.
Actually, I am trying to understand catkin working.
I have some requirements to append to the variables imported by catkin setup.sh.

Hi,
I'm wondering what is the minimum hardware requirement for ROS? We are trying to build a rover with least power consumption. So we need to select the hardware which is energy efficient and can have ROS run on it.

I am trying to get the Oculus Rift DK2 working with rviz using oculus_rviz_plugins but, on Rviz, I always get the message '' No Oculus device found! ".
I am running Ubuntu 12.04, ROS Groovy, Oculus DK2.
After some googling, I suspect this issue happens because of the resolution. I am using DK2 so the only resolutions available are 1080x1920 and 1080x948. Should I be using 1280x800 (DK1) for the Oculus to work with rviz? manually setting it with xrandr does not seem to work...
This is the output I get when I try to run the Oculus Display Plugin on Rviz
OVR::DeviceManagerThread - running (ThreadId=0x7ff9b811c700).
OVR::DeviceManager - initialized.
OVR::DeviceManager - shutting down.
OVR::DeviceManagerThread - exiting (ThreadId=0x7ff9b811c700).
and on Rviz it just says:
'' No Oculus device found! ".
The OculusWorldDemo.sh example from the SDK works fine with video and perfect head tracking, only Rviz cant find it.

I get same message "No Oculus device found!" with Oculus Rift DK2 , Ubuntu 12.04 and ROS Hydro.
Comment by Fred Eduardo on 2014-09-24:
Yeah I am pretty sure rviz_plugins simply does not support DK2. I am new to ros and rviz so I don't have the expertise, but I really want develop these patches for the dk2 to work on rviz. Anybody else willing to work on it? You guys think simply porting it to use the new oculus sdk might be enough?

I have Ubuntu 14.04, and installed ROS Indigo using the steps documented here, but auto-completion using for $ roscd <package_name> gives the following error:
rospack: error while loading shared libraries: libboost_filesystem.so.1.46.1: cannot open shared object file: No such file or directory
rosstack: error while loading shared libraries: libboost_filesystem.so.1.46.1: cannot open shared object file: No such file or directory
So, I purged everything (boost and ROS) and re-installed ROS, with the exactly same results as above
Installed Boost version: 1.54.0-4ubuntu3.1 (via dpkg)
Installed rospack version: 2.2.5-0trusty-20140904-1937-+0000 (via dpkg)
Any ideas why?

Can you check which version of rospack you are calling (which rospack)? And which version of rospack and boost you have installed (dpkg -l | grep rospack, dpkg -l | grep boost)?

which rospack?

Please run ldd /opt/ros/indigo/bin/rospack and post the line listing the boost filesystem library. Please run ll /PATH/TO/libboost_filesystem.so.VERSION to double check that it is not a symlink to an older version.

Hi all,
This looks like a problem of contacts simulation parameters... Let me give more details:
I am currently trying to emulate mecanum wheels using ros indigo and gazebo 2.2 thanks to a trick I found in the VREP implementation of the youbot (see here). They actually use the hierarchy shown below for a single wheel and update the direction of the axis of revolute joint 2 at each frame:
Hierarchy for a wheel:
mobile platform base link
continuous / revolute joint 1 (its axis is the axis of the wheel – or motor, this is the joint which is actuated)
visual representation of the wheel (this is the mesh of the mecanum wheel)
dummy collision and inertia
continuous / revolute joint 2 (its axis is oriented at 45°, along the direction of the contacting roller and crosses the COM of the wheel)
collision geometry (this is a collision sphere)
I implemented this hierarchy for each wheel (urdf file here) and coded a gazebo plugin which performs the axis alignment computation (plugin code here). The system turns out to work ok when moving in the principal direction of the mobile robot (all mecanum wheels turn in the same direction), but when attempting to move sideways (2 opposite mecanum wheels rotating in one direction the two others in the opposite direction), the mobile robot moves as expected for a few frames but then goes back and forth in a way which is not realistic. It looks like a problem with contacts so I played a bit with the mu, kp and kd values of the link in contact with the floor but that did not help.
I have put some videos illustrating the working case when going frontwards (video here) and the problematic case when going sideways (video here). The simulations are stepped by hand to better show the problem.
On the second video (problematic case), the torque applied to the wheels is constant during the whole course of the simulation, hence the mobile movement should be sideways in the up direction. But we observe the wheels accelerate / slide before the mobile platform changes direction back and forth (up and down on the screen). This is very unintuitive.
If I replace the mecanum wheels with normal wheels, all is as expected. The orientation of wheel axes realigned at each step look fine from the printfs.
I am not sure what to do and feel a bit lost... Anyone has an idea of what I could change to improve things?
Thanks,
Antoine.

Hi All,
I would like to synchronise two sensor inputs with a tf::messageFilter. How would I go about connecting both message_filters::subscribers to a single tf::messageFilter.
I have tried to sync both the subscribers via a synchroniser using an approximate time policy. I would like to connect this to the tf::messageFilter
In the header file I have:
tf::TransformListener m_tfListener;
typedef message_filters::sync_policies::ApproximateTime<sensor_msgs::NavSatFix, sensor_msgs::Imu> MySyncPolicy;
message_filters::Subscriber< sensor_msgs::NavSatFix > *m_gpsSub;
message_filters::Subscriber<sensor_msgs::Imu> *m_imuSub;
message_filters::Synchronizer<MySyncPolicy>* sync;
tf::MessageFilter< sensor_msgs::NavSatFix, sensor_msgs::Imu>* m_gpsFilter;
in the .cpp file I have
m_gpsSub= new message_filters::Subscriber<sensor_msgs::NavSatFix>(private_nh, "fix", 5);
m_imuSub = new message_filters::Subscriber<sensor_msgs::Imu>(private_nh, "imu", 5)
m_gpsFilter = new tf::MessageFilter<sensor_msgs::NavSatFix, sensor_msgs::Imu>(m_tfListener, odomFrameId, 10)
sync= new message_filters::Synchronizer<MySyncPolicy>(MySyncPolicy(20), *m_gpsSub, *m_imuSub);
m_gpsFilter->connectInput(sync);
m_gpsFilter->registerCallback(boost::bind(&SwarmbotMCL::gpsCallback, this, _1, _2));
however It complains that tf::MessageFilter can only take one input:
error: wrong number of template arguments (2, should be 1)
/opt/ros/hydro/include/tf/message_filter.h:106:7: error: provided for ‘template<class M> class tf::MessageFilter’
does anyone know of the correct way to do this?

Hello,
I'm using Hydro, Ubuntu 12.04 and I installed Moveit from the source.
When I try to load my .urdf with the setup_assistant, moveit prints that:
[ INFO] [1411283688.252217911]: Loaded motoman_mh5 robot model.

In other computer with the same system, it works. So I assume that the .urdf is ok.
Thanks!
Running it with GDB, that is what I get:

I have installed rosserial_arduino on my RasPi and my Arduino code for Push Button has been uploaded successfully.
To run the code, I am following the following steps as mentioned in the tutorial:
Startup roscore using roscore
Run the run the rosserial_python serial_node.py using rosrun rosserial_python serial_node.py _port:=/dev/ttyUSB0
Watch button status on rostopic echo pushed
Now, the issue here is that when I try step 2 using rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0 (my Arduino is on ACM0), the error message I receive is
[ERROR] [WallTime: 1411295710.119812] Error opening serial: could not open port /dev/ttyUSB0: [Errno 2] No such file or directory: '/dev/ttyUSB0'
For some reason, it keeps taking USB0 as the input even if I specify ACM0 as the port. This error does not occur on my Ubuntu 14.04 distro running Indigo. My RasPi is running Groovy.
I have also added the necessary group permissions (adding user to dialout, etc.) but to no avail. Please suggest methods to solve this issue.
Thanks to ahendrix for having found out the problem. But there is a follow up issue here. Please check.

I use following launch file to run hector mapping on turtlebot. It don't gives any error also don't create any map. When I enter rosrun map_server map_saver -f ~/mymap mymap.pgm is light gray image.
Original launch file
<launch>
<include file="$(find turtlebot_gazebo)/launch/turtlebot_empty_world.launch" />
<include file="$(find hector_mapping)/launch/mapping_default.launch">

cross check laser is published in base_footprint frame.
Comment by serdar on 2014-09-22:
@bvbdort Is it wrong that laserscan_nodelet_manager is publishing scan? In rviz I can see laser scan in /scan topic.
Comment by bvbdort on 2014-09-22:
check the frame id of laser scan it should be base_footprint or any other frame which has tf with base_footprint. Can you share your rosrun tf view_frames output.
Comment by serdar on 2014-09-22:
@bvbdort I added rosrun tf view_frames output to question body.
Comment by bvbdort on 2014-09-22:
what is the frame id of laser; you can view it from rostopic echo /scan
Comment by bvbdort on 2014-09-22:
Also use
Comment by serdar on 2014-09-22:
@bvbdort frame id of scan is /camera_depth_frame.
Comment by bvbdort on 2014-09-22:
use <arg name="pub_map_odom_transform" value="false"/> , hope it works
Comment by serdar on 2014-09-22:
@bvbdort When I pass false to pub_map_odom_transform, in rviz Transform status section it prints No transform from [map] to [base_footprint].
Comment by bvbdort on 2014-09-22:
Change frame in rviz to map to view map
Comment by serdar on 2014-09-22:
I always change but it always shows light gray square, never draws map.

Dear all.
i 'm using ubuntu 12.04 ,turtlebot1 and hydro,created a catkin_ws workspace , installed sbpl through sudo apt-get install ros-hydro-sbplthanks to Johannes https://github.com/meyerj/sbpl_lattice_planner and ahendrix https://github.com/trainman419/sbpl_lattice_planner , i download Johannes's and catkin_makesuccessfuly,but when i
roslaunch sbpl_lattice_planner move_base_sbpl_fake_localization_2.5cm.launch
it came out two errors,ERROR: cannot launch node of type [stage/stageros]: can't locate node [stageros] in package [stage] ,ERROR: cannot launch node of type [nav_view/nav_view]: nav_view . when i rospack find stage and stage_ros in the path'/opt/ros/hydro/share/'
my questions are:
in the move_base_sbpl_fake_localization_2.5cm.launch,how to correct the line <node pkg="stage" type="stageros" name="stageros" args="$(find sbpl_lattice_planner)/worlds/willow.world" respawn="false" >to fix the first error?
in the sbpl_lattice_planner/launch/move_base/nav_view_sbpl.xml,how to correct the line node name="nav_view" pkg="nav_view" type="nav_view" respawn="false">to fix the second error(i want to use rviz to replace nav_view,but don't know how to do ),does the 'remap from ...to ...'lines also need to be changed ?
in the sbpl_lattice_planner/launch/move_base/move_base/move_base_sbpl.xml, does the line <param name="SBPLLatticePlanner/primitive_filename" value="$(find sbpl)/matlab/mprim/pr2.mprim"/> fit my turtlebot1 (it can only forward ,backward and rotation)?
thanks to your time and suggestions !!

I am using an Odroid U3 with my robot, Ubuntu 14.04. I am using an external computer to launch the ROS node of the robot.
I was wondering if there is a way to start ROS in the robot after the Odroid starts up. Like if the robot were turned on with the ROS node running after the startup. That way I would not have to use the external computer. Right now I do not need to monitor the robot so it is OK if I do not have a roscore running externally.

I has frute then I remove it and I downloaded hydro. I followed the steps until I reached to this step:
sudo rosdep init
I got the following error:

Hi all,
Based on some condition in node, I want to start and stop hector slam . (in parallel)
I had looked at different questions and rosspawn but couldn't figure it out.
if(start_node == true)
{
// start node in parallel
// Here my case is hector SLAM
}
if (stop_node == true)
{
// Stop the node
}
Any suggestions ?
thanks.
Edit ::
I found starting node in another package in python code from Roslaunch-API Usage. I am looking for similar way in C++ also starting nodes with params and arguments.
import roslaunch
package = 'rqt_gui'
executable = 'rqt_gui'
node = roslaunch.core.Node(package, executable)
launch = roslaunch.scriptapi.ROSLaunch()
launch.start()
process = launch.launch(node)
print process.is_alive()
process.stop()

Hi,
i have multiple launch files which are started from a shell script after the booting of the computer which is on the robot.
For some reason this creates multiple directories in $HOME/.ros/log. To find the correct logfiles if we have to debug something is kind of annoying as the files are in all of the directories and we have to check quite a few to find the file which has the newest data written into.
Is there a setting to set the log dir for all nodes? The ones started from roslaunch as well as the roscore which is started with the roscore command and the nodes with are running from rosrun.
thank you.

Can you maybe just include all launch files in a single launch file?

Hi all,
as stated here (http://arduino.cc/en/pmwiki.php?n=Tutorial/Memory) adruinos usually do not have much SRAM and it is easy to use it all up by using many constant strings
Notice that there's not much SRAM
available in the Uno. It's easy to use
it all up by having lots of strings in
your program.
<sarcasm warning> The nice feature of the arduino IDE in this cases is that it does not fail to compile or upload but only the arduino programm will run 'strangely' </sarcasm warning>
If you run out of SRAM, your program
may fail in unexpected ways; it will
appear to upload successfully, but not
run, or run strangely. To check if
this is happening, you can try
commenting out or shortening the
strings or other data structures in
your sketch (without changing the
code). If it then runs successfully,
you're probably running out of SRAM.
I have observed this behaviour with my arduino code that uses ros_lib. One of the causes is that ros_lib stores for each topic (publish/subscribe) 3 strings ( md5sum, message type name and topic name ). Particularly if I use topics with namespaces if have observed the problem on arduino uno after setting up only 3 or 4 topics.
How the question: Has anyone considered modifying the message generator for Ardunio such that it uses PROGMEM for storing md5sum, topic and stuff? (Or is it even possible?)
http://www.arduino.cc/en/Reference/PROGMEM
The data is static and I think this would significantly reduce the SRAM usage....
Thank you!
Edit 22.09.: anyone?

You might want to try and just report this as an issue over at the ros-drivers/rosserial github repo. Do refer to this post in your issue.

I am trying to implement some TF under groovy, but ran into compilation errors quickly. I just installed a fresh Ubuntu 12.04 with ROS Groovy. To be sure, I tried to implement the tutorial (http://wiki.ros.org/tf/Tutorials/Introduction%20to%20tf) to see if the error also replicates there when compiled, and it does:

Anyone had this issue before?
Thanks!

EDIT SOLVED:
In the tutorial it says (see below) that you have to change line 14 of the code. I did that but then I get the error. If I switch back to the original code, then it compiles fine!
"Looks like Quaternion API has changed (sorry but not sure when it occurred...Here it's assumed at some point between electric and fuerte) so that the order of the arguments needs changed (Relevant QA thread). That said, if you're on a version prior to the API change, you need to change line 14 to:
q.setRPY( tf::Quaternion(msg->theta, 0, 0) );"
Please also take a look here if you have this error: http://answers.ros.org/question/45884/turtle-tf-tutorial-fails-to-work/?answer=47845#post-id-47845

There seems to be an error when using catkin_make to create the ROS workspace using groovy distribution. When i type the catkin_make command to do environment setup in ~/catkin_ws/src, this is the error message i see.

I am trying to install Baxter on ROS groovy from catkin workspace where the SDK resides, and use wstool to install and update. This is waht i am supposed to do:-
$ cd ~/ros_ws/src
$ git clone [email protected]:RethinkRobotics/baxter_simulator.git
# IMPORTANT EARLY-DEV-RELEASE STEPS:
$ cd baxter_simulator
$ git checkout early_interface_dev
$ cd ..
$ wstool init # need to do this only if this is a new workspace where this command was not executed before.
$ wstool merge baxter_simulator/baxter_simulator.rosinstall
$ wstool update
But after i type in i get this error message. please explain the reason and solution.
sa@svs-FX6860:~/catkin_ws/src/baxter_simulator$ git checkout early_interface_dev
error: pathspec 'early_interface_dev' did not match any file(s) known to git.

So, I'm having an issue with compilation after moving to an indigo platform on ubuntu 14.04. As I understand it, from here, here, here, and here the FindEigen.cmake is now in /opt/indigo/share/cmake_modules/cmake/Modules/. I see this on my system, and I followed the instructions to add cmake_modules as a dependency in both the package.xml and CMakeLists.txt, however, I still get the same error.
The exact error message i get is:
CMake Error at /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake:75 (find_package):
Could not find a package configuration file provided by "eigen" with any of
the following names:

Add the installation prefix of "eigen" to CMAKE_PREFIX_PATH or set
"eigen_DIR" to a directory containing one of the above files. If "eigen"
provides a separate development package or SDK, be sure it has been
installed.
Call Stack (most recent call first):

See also "/home/pachu/flor_repo/catkin_ws/build/CMakeFiles/CMakeError.log".

So... I'm not really sure what else to try. I was working with vigir_atlas_ros_control/vigir_atlas_controller/CMakeLists.txt to add the dependencies but nothing seemed to change. Do i have to change something in /opt/ros/indigo/share/catkin/cmake/catkinConfig.cmake? Any help would be greatly appreciated.

hello everyone.
i've just installed last ubuntu's release on my computer (it seemed a good idea), then i tried to install even last release of ROS.
Sadly, that's what i get:
ubisum@biagioPC:~$ sudo apt-get install ros-hydro-desktop-full
Reading package lists... Done
Building dependency tree
Reading state information... Done
Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:
The following packages have unmet dependencies:
ros-hydro-desktop-full : Depends: ros-hydro-desktop but it is not going to be installed
Depends: ros-hydro-simulators but it is not going to be installed
E: Unable to correct problems, you have held broken packages.
do you know any breakthrough? thanks.

Hi all.
I'd like to translate /cmd_vel(geometry_msgs::Twist) to ackermann_msgs::ackermannDrive.
Linear speed is same in two msgs.(linear.x = speed)
How can I covert angular velocity to steering angle?(angular.z --> steering_angle)
Are there nodes for it? I couldn't find to translate from angular velocity to steering angle.
Could you please let me know equation and necessary parameters?
Thanks.

Hi all, at first ;) my Ubuntu is 12.04 and my gazebo version is 1.9.1 and also my Ros is hydro. I have a simulated kinect in gazebo and i need the color of points, I’ve write below code that i get the data of simulated kinect and converted to pointcloud, also i tried two method that second one is in comment but when i print the color, it's empty but all other thing is ok, any one can help me?
void readkinectCallback(const sensor_msgs::PointCloud2& msg)

Hello,
I'm using the openni_camera and openni_launch stacks with ROS fuerte on a platform with low processing power.
I only need two topics: /rgb/image_rect and /depth_registered/image_rect. Is there a way to only publish those topics in order to speed up the processing time?
Thanks,

Update: 3 images one with after set position issued. One with global map on, one with global map off, and the gazebo image of the simulation.
Update: setting the static map parameter to false in the global_costmap yaml file and the blue map line disappears. Not sure why since the static map is blank. Turning off the Global Map panel (topic: /move_base/global_costmap/costmap) in rivz also makes the blue line go away.
Update using a the light blue crescent map shape is coming from
nav_msgs::OccupancyGrid topic /move_base/global_costmap/costmap. When I toggle the global panel off this line disappears. Not sure what this line represents. Robot still runs backwards in both rviz and gazebo if DWA is on.
When I run with the local cost map parms below my robot in rviz and gazebo run backwards and it plots no local (green) path. The aqua blue dots seem to be map related while the red dots are laser. Note they seem to have different orientations. But why?
global_costmap:
global_frame: /map
robot_base_frame: /base_link
update_frequency: 30.0
publish_frequency: 30.0
static_map: true # note setting to false removes blue line
width: 20.0
height: 20.0
origin_x: -10.0
origin_y: -10.0
local_costmap:
global_frame: /odom
robot_base_frame: /base_link
update_frequency: 10.0
publish_frequency: 10.0
static_map: false
rolling_window: true
width: 16.0
height: 16.0
origin_x: 0.0
origin_y: 0.0
when I run with
static_map: true
rolling_window: false
my robot runs forward and does display a current local path. These are the only changes I make to get this results. Static map can be set to false here and as long as DWA is false also it will move forward.

What release are you running?
Comment by David Lu on 2013-10-25:
Also, the blue dots are your laser scans, and they are where you expect them to be?
Comment by rnunziata on 2013-10-25:
I am running the latest hydro and gazebo 1.9. The blue dots do not make since to me...since the laser is pointing in the opposite direction. The active laser scan are the red dot and cresent line above the yellow goal arrow. The blue dots are maybe the map data but why are they on the other side.
Comment by dornhege on 2013-10-29:
You have displayed global costmap and shown the local costmap parameters. Can you check global costmap parameters.

Odd. Can you give a zoomed out full resolution version of just the data from /move_base/global_costmap/costmap and whatever whatever your laser scan is?

Comment by rnunziata on 2013-11-01:
Hold on...I believe my static map was not as clean as I thought on second inspection. dots so small you can hardly see them in GIMP Image editor. The map was probably bad orientation to begin with. Sorry to waist you time.

Hi,
I'm programming in c++ and I use catkin. I wanted to work with amcl node. But since it's not catkinised yet, I had to use the gmapping node. I followed the tutorial from here:
http:// wiki.ros.org/ catkin/ Tutorials/ using_rosbuild_with_catkin
to get this node. I did each step. Now I want to run the node with the command
$ rosrun gmapping slam_gmapping
scan:=base_scan
but it doesn't work, see the error message :
[rosrun] Couldn't find executable
named slam_gmapping below
/home/pauline/ros_ws/gmapping/gmapping
(I found the command to run it in here http:// wiki.ros.org/ gmapping)
I don't understand because I did
$ rosmake gmapping
and it was successfull. Am I missing something here ??
Thanks for your help

I'm currently writing a node that uses a 3rd party library. This library listens for multi-cast data streaming on port 1001. The problem I'm running into is that it requires root privileges to bind to this port (or any port <= 1023).
There isn't anything I can do to change the port number that I'm aware of, and (a) I don't want to have to run the node as root, especially since this node is likely gong to be distributed, and (b) as far as I can tell running the node as root isn't possible even if I wanted too.
Does anybody know what I might be able to do to listen to port 1001 from within my node?

Pioneer P3-DX
Hi,
I have two simple questions about the settings on pioneer mobile robot
Question 1:
The pioneer robot is giving a beep when it does not recieve any command from the joy stick. It does not give a beep when it receives commands to move. Could any tell how to change these beep settings ?
Question 2:
I have to press a push button on the top of Motors to start the pioneer after reset. Is it possible to not press the push button and yet get the pioneer mobile robot to move ?

I have lots of problems rebuilding hydro too. One hint, try to run brew install for all necessary libraries and programs. I basically had to almost rebuild everything. The problem now is how to build vtk and pcl.
Comment by Hansg91 on 2013-10-24:
Did you run brew upgrade ? Or did you remove stuff from brew and reinstalled them?
Comment by William on 2013-10-24:
I think you need to relink everything, I haven't updated yet, but I have heard that libc++ is now the default rather than libstdc++, which is likely to cause problems (I have not confirmed that). If you run into specific compile errors like with KDL, I would suggest filing tickets directly against them.
Comment by William on 2013-10-24:
That's re-linkedit, not brew link.
Comment by Hansg91 on 2013-10-24:
What do you mean relink everything? I mean I understand, but how do I do that?
Comment by William on 2013-10-24:
I think the easiest way is to uninstall and reinstall.
Comment by Hansg91 on 2013-10-24:
I was afraid you'd say that :(, I will give it a shot
Comment by Artem on 2013-10-24:
William is right about libstdc++, that was the issue. I did brew uninstall and then brew install for most of the packages. William have you updated hombrew pcl? As far as I remember your formula was pulling binaries? Now it has to be compiled :(
Comment by William on 2013-10-24:
@Art the binary for pcl in Homebrew should be specific for mountain lion, you'll have to build it from source, which should be possible with the --build-from-source option to brew. I'll try to get a new bottle as soon as possible.
Comment by Hansg91 on 2013-10-24:
I am now also stuck at compiling PCL through brew. It seems to need some functions in vtk which do not exist. Is there perhaps a version mismatch? ps. I had to disable some python cmake settings for vtk for it to compile and had to enable VTK_USE_SYSTEM_TIFF.
Comment by Hansg91 on 2013-10-24:
Seems pcl1.7 was not ready for vtk6: https://github.com/PointCloudLibrary/pcl/issues/199

I built fully functional PCL after applying a few patches. The source files can be found here https://github.com/Lenskiy/pcl

I Already have the PCL installed, with vtk5. What packages should I reinstall to get orocos_kdl working? @William
Comment by William on 2013-11-22:
@Bruno Normande Not sure, I still have not upgraded to 10.9 myself.

Hi folks,
how are things like AMCL, gmapping and odometry combined?
We're building a robot that will be capable of localizing itself within its environment by using a fixed triangulation system (called beacons). This system tells the robot its X and Y coordinates within the map. So the robot knows its current position pretty well.
Orientation however is measured by a gyroscope. Its angular velocity value is integrated over time to extrapolate the robots orientation. It most likely will be drifting.
Besides the gyroscope/accelerometer the robot will also have access to rotary encoders which measure the distance that its wheels will drive.
And the third thing the robot will likely get is a laser scanner. However there might be other moving obstacles in the range of the laser.
Now, how could we combine pretty well known absolute localisation with laser scan, drifting orientation and odometry by means of AMCL and gmapping?
Thanks a lot!
Cheers,
Hendrik

In roscpp we can use the ROS_*_THROTTLE(..) macros, but rospy doesn't seem to have anything like that.
Any suggestions as to what would be the most elegant / pythonic way of achieving something equivalent in rospy?

You should add how you configured your costmaps, especially their origins and staticness.

I have modeled an environment using a CAD software. I would like to convert this CAD model into .xml format so that the ROS recognizes it. Suggestions would be helpful.

I am working on some forked code that is setup for tf and on my BeagleBone Black I only have tf2. I have most of the code working but it is erroring out on sendtransform with
TypeError: sendTransform() takes exactly 2 arguments (6 given)
I am not sure what to change to the new format. I haven't found a way to get the recipe to cross compile tf. But in the long run it would be better to convert over.
I am working on base_controller.py on my github account FriedCircuits\Ros_Arduino_bridge
(can't post links yet)
Any help to convert it to tf2 would be great. I haven working on this for weeks on the BBB and I am pretty close to having something functional.
Thanks!

Hello.
I need to use a modified version of the prosilica camera driver in Ros Hydro. I have followed the tutorials and I have set up an overlaying catkin workspace with rosbuild. Everything seems fine, but when I try to build the package, all I get is a lot of messages saying the packages are marked with a ROS_NOBUILD flag and I cannot wonder why.
The output of rosmake is:

[ rosmake ] No package specified. Building ['prosilica_camera']

Finally I have managed to build the package with make and adding a Makefile with the following line:
include $(shell rospack find mk)/cmake.mk
But I cannot install it, or use it from the location of the workspace, so I have to manually copy the files in the ROS_ROOT.
Any idea about how to build it with rosmake?
Any idea about how to install o use the package compiled with make, without manually moving the files to ROS_ROOT?

Hi all!
I've just followed this tutorial to create an offline mirror of the ROS Wiki and API, but the API is only populated with diamondback and independent API folders. Where have Fuerte, Groovy and Hydro gone? It there something wrong with the mirror scripts or the website?
in folder roswiki/doc I've executed
$ ls -lah

After installing OSX 10.9, PCL does not build anymore. There were a few compilation and linking problems related to VTK 6.0, that I resolved somehow see this discussion.
Now there is a compilation error

there seem to be some differences in the protocol
see
http://support.robotis.com/en/product/dynamixel_pro/communication/instruction_status_packet.htm
and
http://support.robotis.com/en/product/dynamixel/communication/dxl_packet.htm
however, on the dynamixel pro communication site robotis states
Dynamixel protocol 2.0
Previously both Dynamixel and Dynamixel PRO implemented a different protocol. TO verify protocol version please refer to both instruction and status packet.
unfortunately i couldn't find any information if the ros-dynamixel package will support the pro servos

Since this isn't actually ROS related, you might do better with the pr2-admins mailing list.

Hi, We have a Velodyne Lidar (HDL-32E)(equipped with IMU) that I am trying to start with it. we have gathered UDP positioning packet(port 8308) which includes gyroscope, accelerometer and temperature measurements. I have a few questions:
1- Should all gyro measurements be negative? (mine are)
2- We get 6 accelerometer measurements (ACC1x, ACC1y, ACC2x, ACC2y, ACC3x, ACC3y). I expected to have 3 acceleration measures. How can I get these 6 to 3 x-y-z accelerations?
3- We get 3 temperature measures? why 3? do they differ?
I really appreciate your help.

I have no access to that device and no experience with it. Maybe others can help.
Comment by joq on 2013-10-25:
Appendix B in the 32E manual does have some diagrams and hints: http://velodynelidar.com/lidar/products/manual/63-9113%20HDL-32E%20manual_Rev%20E_NOV2012.pdf .
Comment by Michiel on 2014-07-28:
I have the same question 2, how can I get the 3 x-y-z accelerations from these 6 measurements? You already figured it out?
Comment by Heikki on 2015-12-04:
In order to get the orientation and accelerations out of these 6 measurements, you should use some IMU algorithm. For example this: http://dx.doi.org/10.1155/2015/503814 and it has source code available here: https://github.com/hhyyti/dcm-imu
Comment by joq on 2015-12-04:
Note: there is now an experimental velodyne_gps_imu package in github. It's currently in the gps_imu branch, not yet merged into master. Anyone who tries it, please comment on pull request #53

By custom I mean, it's just an iRobot Create with a kinect mounted on it. The laptop that I plan to use has the following specifications -
Intel® Core™2 Duo CPU T9400 @ 2.53GHz × 2
32bit, 4GB Ram, Graphics - Intel integrated graphics controller
Ubuntu 12.04
By primary aim is to be able to run some path planning algorithms based on real time data from the kinect.
So which version of ROS would you say is more stable for this work?

Can some one please provide steps to configure the server side (ROS) and any details which needs attention on the polyscope touch screen interface.
Any help in this regard will be good. Thanks in advance.

Are you able to ping your robot?
Comment by MKI on 2013-10-27:
Hi Shaun, Yes, I was able to ping the robot, I defined the Robot and My PC to have static IP addresses. Robot is configured listen on port 30000. When I launch ur5.launch, I get warning msgs stating that, I have not configured the calibration offsets for joints. Awaiting your response, Thank you.

I want to display a map on android tablet. I have a gapping node which publishes a "map" topic. To display it I followed make_a_map tutorial from android apps, that can be found on rosjava github. Unfortunately instead of displaying a map, application crashes due to out of memory problem. What am I doing wrong? How can I access OccupancyGrid message and display its content on my tablet?
Map info taken from rostopic echo map_metadata:
resolution: 0.0500000007451
width: 4000
height: 4000
My tablet is Samsung Galaxy note 10.1 which has 2GB RAM, 1,4 GHz quad core CPU and runs on Android 4.1

How large is your map? I suggest you edit your question to include the map metadata info (e.g. rostopic echo /map/info ) as well as maybe some details about what type of tablet you are displaying on. Out-of-memory issues might be completely reasonable with a large map and a low-memory device.

thank you for your comment. I edited my question.

I'm not sure what's causing this but catkin_make ignores dependencies for one or two of my packages.
The package x_competitor_layer depends on the message generation of x_eth_interface. I've added this dependency in
package.xml (build_depend and run_depend)
CMakeLists.txt (x_eth_interface in find_package as well as x_eth_interface_generate_messages in add_dependencies)
of x_competitor_layer package.
But still catkin_make doesn't build x_eth_interface_generate_messages first and keeps complaining about a missing header file. I can solve this problem manually by calling catkin_make x_eth_interface_generate_messages first. But catkin should be able to solve it on its own, shouldn't it?
So what could possibly have gone wrong? What might be missing?
Thanks guys!
Cheers,
Hendrik

Maybe it's a different problem, but have you tried to call catkin_make, a few times in row?

Yepp, I have. Sadly to no avail.

Please provide a minimal rosinstall file for your workspace (or point to repos containing the code in question) which allows to reproduce your issue.

I'm totally a beginner in ROS & Robotics .. I have installed ROS Hydro and set up my workspace + sandbox.
then i started to create enclosure_escape package with 3 dependencies
$ roscd
$ cd sandbox
$ roscreate-pkg enclosure_escape roscpp kobuki_msgs geometry_msgs
now I have to create my c++ code in src folder .. lets say enclosure_escape.cpp
which contains the following code ..
//include libraries
#include <kobuki_msgs/BumperEvent.h>
#include <geometry_msgs/Twist.h>
#include <ros/ros.h>
//define the bumperCallback function
void bumperCallback(const kobuki_msgs::BumperEvent bumperMessage)
{
ROS_INFO("bumper hit. value = [%d]", bumperMessage.bumper);
}
//ROS node entry point
int main(int argc, char **argv)
{
ros::init(argc, argv, "turtlebot_test_node");
ros::NodeHandle n;
ros::Subscriber bumperSubscriber = n.subscribe("/mobile_base/events/bumper", 100, bumperCallback);
ros::Publisher velocityPublisher = n.advertise<geometry_msgs::Twist>("cmd_vel_mux/input/teleop", 1);
//create a Twist message to publish the velocity
geometry_msgs::Twist velMessage;
velMessage.linear.x = 1.0;
velMessage.angular.z = 0.0;
//publish the message
velocityPublisher.publish(velMessage);
ros::spin();
return 0;
}
now the Question comes .. how to run this on turtlebot simulator?

Hi all,
I have started to write some unittests in Python for my nodes and I would like to use existing tests as a model.
I have some experience with GTest (a little less with Python's unittest) but I had never tried to integrate my tests with ROS. Some questions for which I did not find answers in the documentation are: what kind of things should be tested in rostest level? parameters? subscriptions? the code itself? And how are these usually tested? For instance, are the parameters loaded in the rostest launch file or in your Python/C++ code? Even more, how Node-Level and Code-Level tests should be integrated?
I am looking for tests that could help me with the understanding of these concepts (and that maybe could be used as examples in the unittest's tutorials section).
Edit
To sum up my question, I am looking for examples of python's unittest that could be good candidates to put them in the tutorials section (http://wiki.ros.org/unittest)
In essence these examples should illustrate proper ways of using unittest to test the correctness of your nodes. Eg: loading/setting parameters, initialization, publishers/subscribers, etc.

I'm trying the DWA Local Planner as an alternative for the TrajectoryPlanner. At first it moves heading to the given goal pretty fast. But close to the goal, that is about half a meter which still is quite a distance considering that the whole world of the robot is just a plane of 2 by 3 meters, it kind of stops and keeps like dancing in place.
Here's my parameter dump for the local costmap and the DWA Local Planner. There has to be something wrong...
//edit: Okay, I overlooked an error message coming out of the local planner. Here it is:
None of the 94 first of 94 (94) points of the global plan were in the local costmap and free
What might be causing this error?
Thanks for your help!
Cheers,
Hendrik

I'm trying to install Ros Groovy on Fedora 19, following http://wiki.ros.org/groovy/Installation/Fedora. I already had a couple of problems that I have been able to solve myself. However, I don't know how to fix the following problem.
When running
sudo ./src_wet/catkin/bin/catkin_make_isolated --install -DSETUPTOOLS_DEB_LAYOUT=OFF --source-space src_wet/ -j1
this error
pcl/io/include/pcl/io/vtk_lib_io.h:57:29: fatal error: vtkSmartPointer.h: No such file or directory
appears. However, the find command gives the location of that file as /usr/include/vtk/vtkSmartPointer.h. So, why is this error happening?

Hello, everyone!
It's not a question about ROS, but I think many of you met the same problem. I have been writing code that have a part to solve some complicate geometrical problem. The problem had been solved on a sketch by me and I replaced the solution in the code using variable name according to that I use on the sheet. After few week I have lost my sketch and the solution too.. but when I look at the code I have no idea how I have solved it and that all these variables mean. Comments are useful no so better than variable names. And I really need to solve the problem again to understand how it works.
Perhaps someone knows instruments or practices to do the code more self-documented in this case.
Thanks, Aleksey.

At the moment, I control my Husky robot by using a wireless joypad as described in Husky-ROS tutorial
roscore
roslaunch clearpath_base example.launch
roslaunch clearpath_teleop teleop.launch
Since I need to log some parameters (such as left and right linear velocity, encoders ticks, etc..), I use "rostopic echo" and then I re-direct the output to a text file.
For example, I do as follows:
rostopic echo /clearpath/robots/default/cmd_vel >> log-for-vel.txt
After this, I wrote down a bash script which is able to extract only the desired values from the log files.
Typically, each topic file is something like this:
header:
seq: 778
stamp:
secs: 1380713547
nsecs: 429730892
frame_id: ''
left_speed: 0.34
right_speed: 0.34
left_accel: 0.5
right_accel: 0.5
---
header:
seq: 779
stamp:
secs: 1380713544
nsecs: 735946893
frame_id: ''
left_speed: 0.26
right_speed: 0.26
left_accel: 0.5
right_accel: 0.5
And I just need to extract timestamp and left and right velocity information.
Since this is an intricate solution, I would like to know if there is any smarter solution to log these values in a text files without having to redirect the output for each topic.
What's the best solution for my problem?
I really hope you can help me!
Thank you very much!

Hi all,
I've worked on simulated husky with simulated kinect to create a customize 3d occupancy map, i want to transform the pointcloud frame to map or world frame, but i don't have these frames, just i can translate to odom frame, for creating 3d occupancy map, is it enough or i should add a link in my urdf or any thing else to create world frame ?!
Thank you.

H everyone, I can compile the following code in Xcode but I cannot do the same when using rosmake. Here is my .h file:
#ifndef __AStartAlgorithm__AStarAlgorithm__
#define __AStartAlgorithm__AStarAlgorithm__
#include <iostream>
#include <vector>
class AStarAlgorithm{
public:
AStarAlgorithm();
void astar();
void printmap(std::vector < std::vector<int> >map);
private:
};
#endif /* defined(__AStartAlgorithm__AStarAlgorithm__) */
Here is my .cpp:
#include "../header/AStarAlgorithm.h"
#include <iostream>
#include <vector>
AStarAlgorithm::AStarAlgorithm(){
}
void AStarAlgorithm::astar(){
std::vector<std::vector<int> > map = {{8,8,8,8,8,8,8},{8,0,0,0,0,0,8},{8,0,0,0,0,0,8},{8,0,1,0,0,2,8},{8,0,0,0,0,0,8},{8,0,0,0,0,0,8},{8,8,8,8,8,8,8}};
// printmap(map);
}
/*
void AStarAlgorithm::printmap(std::vector < std::vector<int> >map){
for(int i = 0; i < map.size(); i++){
for(int j = 0; j < map[i].size(); j++){
if(map[i][j] <10){
std::cout << "|"<<map[i][j] << " |";
}else{
std::cout << "|"<<map[i][j] << "|";
}
}
std::cout << std::endl;
}
std::cout << std::endl;
}
*/
I want to print out the vector with the commented out code but the problem at the moment is just initialising the vector. Here is my error in ROS:

Hi there,
I'm trying to integrate RGB-D SLAM with the Hector Quadrotor model simulation on Gazebo. The idea is to launch the model of the quadrotor with a kinect and use the visual data recovered by the simulated camera in the running RGB-D SLAM.
What's supposed to be done so this can function right? What topics should be called in each launched file so can RGB-D SLAM Bcan receive data from the simulated Gazebo Kinect?
Thank you! Best regards

I have tried to do the same thing, i got it working (although there is some issues). It required to resolve all dependancy issues and to migrate some old packages into Hydro distro, if you're still interested I could give a few pointers..
Comment by TSC on 2014-01-08:
Hi there! Off course, I'm still interested. Can you please give me some tips, maybe even post some packages to download and use them on Hydro? So you are able to use RGB-D SLAM and Hector Quadrotor both on Hydro? I will need RGBD-SLAM running on Ubuntu ARM.
Thank you
Comment by rock-ass on 2014-01-09:
Yes i'm able to use them on hydro. I can provide updated source code of rgbdslam package to be able to compile on ROS hydro, i will provide the info today. But you want it on ARM? simulator on arm should be a real pain to setup and probably will be of poor performance
Comment by TSC on 2014-01-09:
The only thing I want for ARM is the RGB-D SLAM package, since I will be using visual stream data for navigation of a real quad. But first I need to put the simulation correctly working on Hydro so that I can make a port of the used algorithms on a Odroid board.
Comment by rock-ass on 2014-01-10:
I posted an answer with link to repo, mark it as answered if it helps :) Let me know if you get any results. i am also working on a quadrotor simulation, only i'm using stereo camera only instead of kinect

I am following this page:
http://wiki.ros.org/groovy/Installation/UbuntuARM
and have it working, but cannot find the install package for navigation.
apt-cache search ros-groovy
does not show up a nav package other than nav_msgs.
So, of course,
sudo apt-get install ros-groovy-navigation
just returns this:
Unable to locate package ros-groovy-navigation
How do I get programs like amcl, move_base, etc. installed?

After taking some time to acquaint myself with the KnowRob system, I'm now in the process of writing my own modules using its functionalities. As a simple starting point, I just want to write an action recipe telling my robot to get to the middle of the room (x=0.00, y=0.00), then just move to another point in the map (x=3.00, y=3.00).
I'm using the move_base module for navigation, and the robot is simulated in an empty room (no semantic map is needed as the space is empty).
CPL is not something I want to look into right now, as my time is limited and I think that system would add a layer of complexity that I don't need right now. I know that the KnowRob team has done experiments using action recipes in the past without using CPL and the cogito system.
In order to implement a working application, I decided to extend the KnowRob ontology with data about action execution on one hand, and to write a simple python module to query the prolog system to actually move the robot on the other hand.
This is the core of my extension to the ontology
> <owl:Class rdf:about="&move;GoToPoint">
> <rdfs:subClassOf rdf:resource="&knowrob;Translation-LocationChange"/>
> <rdfs:subClassOf>
> <owl:Class>
> <owl:intersectionOf rdf:parseType="Collection">
> <owl:Restriction>
> <owl:onProperty rdf:resource="&move;providedByMotionPrimitive"/>
> <owl:hasValue rdf:resource="&move;move_base" />
> </owl:Restriction>
> <owl:Restriction>
> <owl:onProperty rdf:resource="&move;destXValue"/>
> <owl:cardinality rdf:datatype="&xsd;decimal">1</owl:cardinality>
> </owl:Restriction>
> <owl:Restriction>
> <owl:onProperty rdf:resource="&move;destYValue"/>
> <owl:cardinality rdf:datatype="&xsd;decimal">1</owl:cardinality>
> </owl:Restriction>
> </owl:intersectionOf>
> </owl:Class>
> </rdfs:subClassOf> </owl:Class>
I added a MotionPrimitive class, of which move_base is a subclass. Each motion primitive provides a providedByROSAction property: a string containing the name of the appropriate ROS actionlib server. My action recipe is thus simply composed as an intersection of various GoToPoint restrictions.
The robot connects to json_prolog and, on being asked to perform the task, asks for
plan_subevents(move:'MovementTest', SEs)
then queries for the appropriate action primitives and, if it is aware of them, queries for the needed parameters and calls the corresponding servers.
I implemented this approach and it works just fine. I know there are a few minor things that should be fixed (e.g. in the ontology points in space should be represented as properties of a PointInSpace class) but I'm afraid about a major issue that this implementation brings up. Mainly, maintaining both the ontology and the robot executor might become very difficult with the number of action servers getting big. It would obviously be also very prone to errors, as the developers would have to both update one and the other, in two different languages.
Am I proceeding in the right direction with this implementation structure? Am I missing something big? Should I use some other built-in feature I didn't see/notice?

Hi, i,ve managed to create some bags starting from some carmen log file.
Now i'm trying to use those bags with for gmapping but while rosbag play doesn't show any error, gmapping get stuck at:
update frame 0
update ld=0 ad=0
Laser Pose= 0 0 0
m_count 0
Registering First Scan
so when i try to get the map file using "rosrun map_server map_saver" only a partial map file is given.
While doing this procedure with the bag given in the gmapping from logged data tutorial nothing get wrong.
one of the bags i'm trying to use is this: db.tt/BawU5lXp
Is there a way to check if the bag is suitable for what i'm doing ? what can be the problem ?

Hi there,
Ubuntu 12.04;
Ros Hydro;
C++;
link page on ROS: tf/Tutorials/Writing a tf listener (C++)
phenomenon: When I tried to follow the tutorial to write a tf listener in C++ and catkin_make it, error cannot find Velocity.h in the system.
I searched and found that there is Velocity.h in Groovy. In this page(remove turtlesim velocity and use Twist msg in Github), jihoonl says we should change turtlesimVelocity.h to geometry_msgs/Twist.h.
How should I change the C++ tutorial code in 'writing a tf listener'? I tried to change it properly, but failed. Any suggestion is highly appreciated :)
Thank you very much.

So I'm trying to wrap my head around which node exactly does the control system for moving a specific distance in the Navigation stack (using current velocity from /cmd_vel). I came to the conclusion that move_base is responsible for this, but now I'm wondering: what kind of control system does it implement? How does it know what cmd_vel to publish in order to reach the specific distance it must go? Is it a PID controller or something?
I'm mostly asking this just to make sure that I understand this right... I basically want to make sure that my robot moves to the designated destination in a controlled manner (not just full speed until it reaches target then stops and overshoots)...

Hi,
I have question, on odom and base_footprint, especially when the robot is falling down or 4-legged walking in REP 120.
I assume that humanoid robot did not know about the current waist position, but can estimate orientation from IMU sensors.
does odom correspond to the sensor based orientation and world reference based position of the waist?
does base_footprint respect the sensor based orientation and model based calculation of the height of the waist?
if it is ok, the question is
how do you estimate the position of the odom, from the walking controllers? does that include any sensor data?
does base_footprint does not reflect any sensor data? what's happens if the robot falling down or 4-legged walking mode?

Hi,
I am trying to implement my own rqt plugin with C++. It consist of a QGraphicsView with few QGraphicsItems.
I did it like in rqt_image_view, basically by copying and adjusting the content of CMakeList.txt, package.xml, plugin.xml, setup.py.
However it is build without any errors when I try to launch it I get a message:
qt_gui_main() found no plugin matching "agent_gui"
I have no idea what can I do wrong here. I have included PLUGINLIB_EXPORT_CLASS macro in source file of my class inheriting from rqt_gui_cpp::Plugin, added appropriate export in plugin.xml. Just like in rqt_image_view plugin and the tutorial.
I use ROS groovy and catkin on Ubuntu 12.04 LTS
Thanks in advance, I appreciate any help.

Hello,
When checking for collision in MoveIt! using CollisionResult, one can get the distance to the nearest collision. Is it possible to also have the normal vector along that distance? Basically, I'm trying to get as much collision information as possible before it happens, so direction in addition to proximity would be very useful.
Thanks,
JML

Operating System Details:
Ubuntu 12.04 LTS (Precise Pangolin) - ROS Hydro
The following command:
rosrun rviz rviz
Briefly displays the rviz logo, before repeating the following error 100 times:
[ WARN] [1383004708.902971662]: OGRE EXCEPTION(3:RenderingAPIException): Invalid parentWindowHandle (wrong server or screen) in GLXWindow::create at /build/buildd/ogre-1.7.4/RenderSystems/GL/src/GLX/OgreGLXWindow.cpp (line 229)
rviz::RenderSystem: error creating render window: std::exception
And then finally giving up with the following messages:
[ERROR] [1383004708.903200106]: Unable to create the rendering window after 100 tries.
rviz: /tmp/buildd/ros-hydro-rviz-1.10.9-0precise-20131021-0017/src/rviz/ogre_helpers/render_system.cpp:374: Ogre::RenderWindow* rviz::RenderSystem::makeRenderWindow(intptr_t, unsigned int, unsigned int): Assertion `false' failed.
Aborted (core dumped)
I've tried re-installing rviz, which didn't help. Also, I was having the same problem before moving from fuerte to hydro (though a long while back rviz was working fine with fuerte). I suspect it has been an update to rviz or ogre which has caused this problem, but I'm not really sure how to go about attempting to repair it..

I read that download_unpack_build.mk is now discouraged:
https://groups.google.com/forum/#!topic/ros-sig-buildsystem/e027agspX24
and it is now recommended to install them from source or using rosdep.
In the past (fuerte), we have used the tool a lot to download exotic libraries that are not released as ubuntu/debian packages, or don't have a Find*.cmake file, etc. Using the download_unpack_build.mk it was really easy to integrate them in our build system. Especially when we wanted to get a very specific version, and/or patch it to adapt to our needs.
Is there a similar solution in catkin?
I understand that it might cause issues on the build farms, but the packages we are working on are not going to be released.

Under what condition would the PID error vector be greater then the set point vector (command sent). This is happening to me using the gazebo ros plugin. Related question is there a way to turn off the PID process in the plugin to run some test.

Hello all,
I have an application where I am using the turtlebot simulator with move_base for some navigation related tasks. So generally, if a goal is specified, I am assuming the nav stack comes up with a spline for a large set of points that when passed through, take the robot there. If I have my own (sufficiently large) set of waypoints; is there a way to avoid stopping at every waypoint and rather let the robot drive through them like a curve?
Thanks,
Sai

Hi guys,
1)
How do you guys set your initial pose if the origin of map is [0.000, 0.000, 0.000] ?
Simply by estimation or there is a way to let us know the exact point we wanted?
2)
Inside this yaml file(map info) there is this resolution, how does the resolution affect as it changes?

Dear ROS users,
i tried to implement a C++ plugin (lets call it rqt_myplugin) following the tutorial rqt/Tutorials/Writing a C++ Plugin and the rqt_plugin ImageView. I am quite sure, that namespaces and classes are well defined in all necessary files. The problem is, that when i am trying to execute my plugin by running
rosrun rqt_myplugin rqt_myplugin
i get the message:
qt_gui_main() found no plugin matching "rqt_myplugin"
Rqt doesn't show the plugin neither.
Could you explain, how rqt is aware of my created plugin? I thought that it should be enough to source devel/setup.bash.
I am using ROS Hydro and Kubuntu 12.10 32Bit.

Comment by Thomas on 2013-10-28:
Did you add your plugin to your ROS path? I.e. what does rospack find rqt_myplugin return? Did you edit the plugin.xml file properly and doe the name match what your put in rqt_myplugin? Please provide us your current plugin.xml file.
Comment by Thomas on 2013-10-29:
Your plugin.xml seems ok. How is called your plug-in? (I mean the .so file)

I've created my own .msg and can perform "rosmsg show MyMessage".
The question is how can I use it in my C++ code?
I've seen this link that is exactly the same question (http://answers.ros.org/question/31779/how-to-use-a-message-that-i-made/) however I don't really get it all. =(
Why is there a Header header in the .msg file? Is it "standard" to have in a msg?
Where Is the MyMessage.h file saved? How do I create It? I can only find the .msg file. Since I can't find it I cant Include it in the cpp file naturally.
It also states that I should add the line in the manifest. When I do this i get an error saying:
The manifest must not contain the following tags: depend
How can I solve this?
Many Thanks, Patrik

Hi,everyone.
I have a Poineer-3DX robot, the onboard computer system now is Windows 2000. I can connect the robot with my laptop(already installed with ROS hydro and Ubuntu 12.04) through a serial line。
My first question is: whether I should install ROS on the onboard computer? If I have to, how to install? The instruction of the installation is not clear.
My second question is :When I send the command
rostopic pub -1 /RosAria/cmd_vel geometry_msgs/Twist '{linear: {x: 0.1, y: 0.0, z: 0.0}, angular: {x: 0.0, y: 0.0, z: 0.0}}'
to the real robot, it can move, but very slowly even I change the linear x velocity to a bigger value, what's the problem? However, if I run the command to the simulator, the change of the velocity works.
Thank you guys.

Comment by autonomy on 2013-10-30:
This is just a guess (from working with p2os), but the robot may move slowly because somewhere in the params the max velocity value is set to a very small number. Sometimes, with ROS nodes, parameters are not documented well. See if you can find it in the source or if there is one set by the sim.

Hello,
I'm trying to properly use Hector slam in simulation using a turtlebot. I'm using ROS hydro and Gazebo 1.9 on ubuntu 12.04. Once I spawned in Gazebo the turtlebot and the world I created, I use this launch file to start hector slam:
<launch>
<param name="/use_sim_time" value="true"/>
<node pkg="rviz" type="rviz" name="rviz"
args="-d $(find hector_slam_launch)/rviz_cfg/mapping_demo.rviz"/>
<include file="$(find hector_mapping)/launch/mapping_default.launch">
<arg name="odom_frame" value="odom"/>
</include>
<arg name="trajectory_source_frame_name" value="scanmatcher_frame"/>
<arg name="trajectory_update_rate" default="4"/>
<arg name="trajectory_publish_rate" default="0.25"/>
<node pkg="hector_trajectory_server" type="hector_trajectory_server" name="hector_trajectory_server" output="screen">
<param name="target_frame_name" type="string" value="map" />
<param name="source_frame_name" type="string" value="$(arg trajectory_source_frame_name)" />
<param name="trajectory_update_rate" type="double" value="$(arg trajectory_update_rate)" />
<param name="trajectory_publish_rate" type="double" value="$(arg trajectory_publish_rate)" />
</node>
<node pkg="hector_geotiff" type="geotiff_node" name="hector_geotiff_node" output="screen" launch-prefix="nice -n 15">
<remap from="map" to="/dynamic_map" />
<param name="map_file_path" type="string" value="$(find hector_geotiff)/maps" />
<param name="map_file_base_name" type="string" value="hector_slam_map" />
<param name="geotiff_save_period" type="double" value="0" />
<param name="draw_background_checkerboard" type="bool" value="true" />
<param name="draw_free_space_grid" type="bool" value="true" />
</node>
</launch>
The slam seems to work when I navigate the robot around, but I'm very surprised by the bad result compared to gmapping. It get lost very easily and the map is very bad. I would like to know if I set up something in the wrong way, or if it depends from the fact that I'm using a fake laser from kinect or maybe that the world in gazebo I created is challenging for hector slam.
EDIT:
If I move the robot only forward/backward the map is correctly reconstructed, but if I make the robot rotate on itself it prints 'SearchDir angle change too large' and it gets totally lost (sometimes it makes position jumps up to 1 meter and more!!).
This is the world I'm using in gazebo:
Many thanks!!

Hello,
I'm trying to adapt the Euclidean Cluster Extraction tutorial from PCL to work with ROS.
I can get the tutorial working as it should, my question is with handling the detected clusters.
My idea was to publish each cluster in a different topic so I can look at them separately in rviz. My question is how can I do that?
Currently I'm creating one publisher as a global variable, and using nodehandle.advertise<sensor_msgs::PointCloud2>() in main() to create a topic and publish on it. This means that I can only publish only one pointcloud through this.
Is it possible to create a number of publishers, unknown at compile time, since I don't know how many objects will be detected, that each publish on a different topic?
How else would you recommend I use/view the vector of PointClouds that get created by the cluster extraction? The tutorial extracts them to files, but I would rather view them in rviz somehow.

I've tried to use my own .msg to send between nodes but I'm having some trouble. I got an answer on It before http://answers.ros.org/question/95406/how-can-i-use-my-own-msg/ but I don not get It to work properly.

add_dependencies(distanceCalc distanceCalc_gen_msg_cpp)
In my case I have projects within my src folder in the catkin_ws, one of them is named distanceCalc and have a folder named msg where the message distanceMessage.msg is placed.
Is there some mistake that I'm making, because when I try to inclide the message with
the line
#include <msg/distanceMessage>
in my cpp file which exists in the src folder in the project distanceCalc I get an error (when trying to perform the catkin_make command) saying
"fatal error: msg/distanceMessage: No such file or directory"?
If this is not enough information to answer the questions please inform me and I will update.

Catkin puts the headers from my custom messages from package1 in
~/ros_ws/devel/include/<package1>/
I want to use them when compiling package2. I am assuming that the CMakeLists.txt for package2 needs a line like
include_directories(
${<WORSPACE_ROOT>}/devel/include
${catkin_INCLUDE_DIRS}
)
but I don't know the correct variable is for the workspace root, ie ~/ros_ws.
The other question is: is there a better way of doing than than manually specifying the top-level include dir?
Here are the CMakeLists.txt files:

which suggests to me that my problem is not with the include directory itself, but something more general with CMake not being able to find stuff. But I have no idea.

Hello dear Community!
Could someone help me with the problem I'm experiencing with Interactive Moveit! markers in rviz with my simple test robot arm.
Please review the link www.youtube.com/watch?v=M1c8A-DfghA and tell me please why I can't change the Goal State with the Interactive Marker? And as you would see from video I can do this through the Planning Tab, setting the random Goal State. What should I do to force Interactive Marker to change the Goal State?
Please help me with this stopper.
Please feel free to ask from me (I do really want find the problem) all that is necessary to help to resolve this problem. I have successfully used pr2_moveit_config tutorial, and Interactive Markers for move groups (like right_arm) out there works fine.
Thanks, Alexey!
