I am trying to install object_manipulation package for ros hydro (which I installed from source) on ubuntu 13.10. To do that I downloaded the source of package from github link and tried to run following command in the downloaded folder:
sudo /opt/ros/hydro/bin/catkin_make_isolated --install --install-space /opt/ros/hydro
However I am getting following error:
Traceback (most recent call last):
File "/opt/ros/hydro/bin/catkin_make_isolated", line 12, in
from catkin.builder import build_workspace_isolated
ImportError: No module named catkin.builder

Hi all,
I'm currently working on a camera driver and I was wondering if any of the ideas I list here are even possible:
Group some dynamic_reconfigure parameters into groups or "boxes" so that the end user can see that those parameters are related. Ex: Acquisition params, Trigger params, White balance params...
Add tooltips or a info box whose content changes when the mouse hovers a particular parameter in the dynamic reconfigure gui.
And I've seen in the tutorials that it's possible to have more than one config file in one ROS package. If the package contains more than one node, then the relationship is easy: one cfg file for each, but could it be possible to have more than one cfg file in the same node? Therefore, could I "group" the parameters I want in different cfg files and show them as a tree in the dynamic reconfigure gui?
I tried groups (even with prosilica_camera example) in dynamic_reconfigure but whenever I open the GUI to see the params, reconfigure_gui crashes:
$ rosrun rqt_reconfigure rqt_reconfigure

the tooltip / info box idea seems useful enough. Maybe you could open an issue on github for future reference.

Hi,
I have been using the individualMarkers node from the ar_track_alvar package successfully. With the individualMarkersNoKinect however, the detected markers are about 5 cm 'below' the right location. Apparently this depth data based improvement is important: if I comment out the
int ret = PlaneFitPoseImprovement(i,
m->ros_corners_3D, selected_points,
cloud, m->pose);
line in the individualMarkers code, I get a similarly large error.
Is that really the best accuracy you can get without using the depth data?
I am using a close range primesense camera with markers not more than 1 meter away from the camera. The marker size is 7 cm.
When using the individualMarkersNoKinect node, I use the following topics:
/camera/rgb/image_raw
/camera/rgb/camera_info
Thanks for any feedback,
Bert

In the meantime, I did a calibration of the rgd camera (using http://wiki.ros.org/camera_calibration) and that improved the 2d based tracking accuracy. The errors are now < 2 cm in the direction from the camera to the marker location. Depending on the camera quality and the calibration quality, I assume now that's the best possible...

i am using hector_slam with laser data of kinect but when i move kinect to create map the map jumps, and does not create a compleate map.
tnx for your seggestions.

Hello,
I'm trying to build ROS from source. The system I am using is:
Ubuntu 13.10
ROS groovy desktop-full
I used this guide to build the system: [I have no karma to post the link]
Ubuntu is a fresh install from disk.
Compiling went well, except that the dependency on the libyaml parser was not solved, I installed those packages and it worked, however when trying to build the collada_parser packages, I get the following error:
kempenaarjj@ce011:~/ros/catkin_ws$ cd /home/kempenaarjj/ros/catkin_ws/build_isolated/collada_parser &&
/home/kempenaarjj/ros/catkin_ws/install_isolated/env.sh make -j2 -l2
[100%] Building CXX object CMakeFiles/collada_parser.dir/src/collada_parser.cpp.o

make[1]: *** [CMakeFiles/collada_parser.dir/all] Error 2

The collada packages I got installed on the system(either via the rosdep dependency command or by manually using apt-get:
kempenaarjj@ce011:~/ros/catkin_ws/build_isolated/collada_parser$ dpkg --get-selections | grep -v deinstall | grep coll
collada-dom-dev install
collada-dom2.4-dp install
collada-dom2.4-dp-base install
collada-dom2.4-dp-dev install
Also a dae.h is present on the system:
kempenaarjj@ce011:/$ find -name dae.h
./usr/include/collada-dom2.4/dae.h
I already found that there were tickets regarding this in the bug tracker, however they do not state a fix.
Which dependency do I need to install here in order to make this package work?
Regards,
Jan Jaap

I have a similar problem on OSX 10.8. dae.h is installed by homebrew in /usr/local/include/collada-dom2.4 [EDIT] never mind, it looks like I just add to re-run CMake for it to find the collada-dom-config.cmake

Hi all,
I am digging deep in this forum, but I'm getting lost. I am using ROS Groovy and receiving a sensor_msgs::PointCloud2 from a depth_image_proc nodelet and I want to process it using PCL 1.7. None of the solutions found in this forum are working for me, i.e., I miss some function prototype of toPCL, fromROSMsg, etc. functions.
I would like to do something like:
void CloudViewerPlugin::pointcloudCallback(const sensor_msgs::PointCloud2::ConstPtr& msg) {
pcl::PointCloud<pcl::PointXYZ> cloud;
pcl::PCLPointCloud2 pcl_pc;
pcl_conversions::toPCL(*msg, pcl_pc);
pcl::fromPCLPointCloud2(pcl_pc, cloud);
or
void CloudViewerPlugin::pointcloudCallback(const sensor_msgs::PointCloud2::ConstPtr& msg) {
pcl::PointCloud<pcl::PointXYZ> cloud;
pcl::fromROSMsg(*msg, cloud);
but I found no function prototype to do this.

Can you try to directly subscribe to a pcl pointcloud? There might be some pcl_ros magic going on that allows you to do so.

Hi Christian,
I already tried that solution, but:
/opt/ros/groovy/include/ros/message_traits.h:121: error: ‘__s_getMD5Sum’ is not a member of ‘pcl::PointCloudpcl::PointXYZ’
on the subscribe line
(I'm following http://wiki.ros.org/pcl_ros)

Sorry, I hadn't #included the right files, however, now there are two errors:
/opt/ros/groovy/include/pcl_ros/point_cloud.h:176: error: no matching function for call to ‘createMapping(std::vector<sensor_msgs::PointField_std::allocator<void > >&, pcl::MsgFieldMap&)’
and:
/opt/ros/groovy/include/ros/serialization.h:134: error: ‘struct pcl::PCLHeader’ has no member named ‘deserialize’
Comment by Rufus on 2020-04-12:
I believe your second option fromRosMsg is only available fron Kinetic onwards

can we choose package to be tested? currently catkin_make test tests all test code under src directory, but I'd like to check only specific packages, in order to save time.

Greetings!
I am soon starting up my new hobby project: a SLAM-robot with no clear goal yet (part from navigation). All the parts have arrived but I need some advice regarding what stack to start with, as I do not want to assemble all software components from scratch. I will start of by presenting the list of hardware.
CPU-board: Hardkernel ODROID-U3
Controller board: Arduino plug-in board for ODROID-U3
Motors: Two pretty fat stepper motors
Stepper motor drivers: Two L298N based stepper motor driver boards
Sensor: Microsoft Kinect
The robot will be assembled on a frame built of sheet aluminium together with a 360º turning nosewheel and airplane wheels for the stepper motors. The Kinect sensor will be mounted on the top of the aluframe.
Now there are several issues that I need to address and I hope that the ROS community can help me with some of them or at leaste provide som useful suggestions.
The ODROID officially supports releases of ubuntu 13.10 and up. As I understand the latest Ubuntu officially supported by ROS is 13.04. Obviously there is a gap here and I have the options of installing a non-supported OS on the ODROID, or compiling ROS from source - I am not very impressed by any of those two solutions. Another option is to run Android but I have a bad feeling about that since it seems very experimental.
I do not want to build my application from scratch as this is a waste of time imho. What I need to figure out is which pre-assembled stack to use in order to get as close as possible to my particular setup. I'd be happy if the only thing I'd actually need to implement in code is the stepper motor interface on the arduino.
What is the recommended workflow for developing the robot application? SSH in and have the build environment located on the ODROID? Cross compile on a PC?
Finally, I am interested in some cool applications for the robot. I.e. vacuum cleaner, spy etc.
Let's get this discussion started!
/Simon

What are implications of catkin_add_env_hooks and Windows? Do they just get ignored, with the intent that they're mainly there to provide window-dressing stuff like tab completion?

Hi,everyone!when I was setting up my robot for navigation ,I followed the navigation tutorial like this .But when I roslaunch the move_base.launch ,I ran into an error.It says ,
You must specify at least three points for the robot footprint,reverting to previous footprint.
I know maybe something is wrong with costmap_common_params.yaml setting "footprint:[[x0,y0],[x1,y1]...[xn,yn]]".But I donot know how to solve the problem.Can anyone help me ???
I add the costmap_common_params.yaml:
obstacle_range: 2.5
raytrace_range: 3.0
footprint: [[x0, y0], [x1, y1], ... [xn, yn]]
inflation_radius: 0.55
observation_sources: laser_scan_sensor
laser_scan_sensor: {sensor_frame: base_laser, data_type: LaserScan, topic: scan, marking: true, clearing: true}

Ok,I add my costmap_common_params.yaml to the question. Maybe I should fill in x0,y0,x1....xn exactly. But I donot know what footprint and inflation_radius means in this file and how much it matters to the algorithm. I have read the tutorial,but canot catch the point .Can you help me?

Is it possible to install an overlay in the same install space as an underlay? For example, if I have a base install from source in /opt/ros/hydro, it might be convenient to extend it with additional packages in an overlayed workspace instead of augmenting the original workspace (which for the desktop-full install has about 250 packages on hydro). If those additional packages are merely dependencies (i.e. I don't intend to modify them) and not specific to one project, installing them on top of the underlay in /opt/ros/hydro would be convenient.

Hello everyone,
I am receiving a pointCloud2 type messages by subscribing to a topic, in my code. Now I need to build an octomap from this. I am currently using Groovy and Octomap libraries for ROS Groovy.
I have gone through the documentation of octomap, but couldn't retrieve much from that. The function octomap::insertPointCloud() is somewhat close to my requirement.
Is there a way to create an octomap using this API for the callback being received ? And can I eventually write an octomap-file to the disk using some function ?
I have gone through few threads like this also but not able to get a concrete idea.
http:// answers.ros.org/question/89906/how-to-generate-an-octomap-from-a-point-cloud-with-hydro/
I'd be grateful if someone can point me to an example code for the same or the order we need to follow to achieve this ?
Thanks.

Hi All,
I'm sure I've seen that rviz has a virtual joystick plug-in. Any idea where I might find it (Publishing twist messages)? Looked around rviz/these answers and google and it doesn't seem obvious. (Unless I'm imagining things of course! :) )
Many Thanks

I have created a simple but functional/complete node for frontier exploration using the hydro costmap_2d layers, but I'm unsure how 'mature' something should be before I should be releasing it.
I thought it was a huge pain that 'explore' was unmaintained, and all the other exploration packages were coupled to larger stacks.
I've ad-hoc tested it pretty thoroughly, and would like to squeeze out some time in a month or so to implement some proper tests and documentation, but for now I'd just like to get the code out there and find out if anyone else is interested in using, contributing, pointing out glaring mistakes, or suggesting functionality.
Is this ready to be released into the wild via bloom?

Hi, I just wanted to know if there is some example on getting sonar and bumper data from a pioneer3dx using p2os, I can't find anything. I thought it was like getting pose data but now I think it's nothing like that. Can you help me?
It seems like p2os does not offer access to bumper data, but is it possible in any way?
Thanks in advance.

Hi all,
I have a question regarding the usage of ar_pose with kinect.
So, what I did so far. I rosmake the ar_pose node and to make everything run I execute the following commands:
roslaunch openni_launch openni.launch
(for kinect)
and
roslaunch ar_pose ar_pose_single.launch
In the list of topics I have /ar_marker, /world and topics related to the camera. I tried choosing different topics for fixed and target frames as well as for camera topic. I am getting an image from the camera, but the target (I use standard pattHiro.pdf mentioned in ros wiki for ar_pose) is not recognized.
I also tried changing options for my kinect in launch file, but without success.
Here is the content of the launch file for ar_pose:

I want to integrate a state machine using the smach libraryto my robot but when I tried running the first tutorial I got this error message/
ImportError: No module named smach/
On the documentation page I found no installation instructions. Does smach come standard with groovy and I am importing wrong or does it need to be install it separately when using groovy?

I followed the tutorial here => wiki.ros.org/navigation/Tutorials/RobotSetup/TF on the TF (sorry my karma doesn't allow me to post link) and I had those lines at the end of the make file
add_executable(tf_broadcaster src/tf_broadcaster.cpp)
add_executable(tf_listener src/tf_listener.cpp)
target_link_libraries(tf_broadcaster ${catkin_LIBRARIES})
target_link_libraries(tf_listener ${catkin_LIBRARIES})
Then I used catkin_make that compile without a problem but when I use
rosrun robot_setup_tf tf_broadcaster
I have in my terminal this
[rosrun] Couldn't find executable named tf_broadcaster below /home/ros/catkin_ws/src/robot_setup_tf
After a few search it appears that the file is actually situated here
/home/ros/catkin_ws/devel/lib/robot_setup_tf
I can launch it manually and it's working perfectly, it just that I can't understand why it's there and not in the src folder of the robot_setup_tf. If someone could explain to me.

Recently, I discovered a process on my ubuntu that was eating away at both processor time and memory, 18% and 10% respectively. Avahi-daemon and I got rid of it along with pulseaudio. It seems to me that there is no need for avahi-daemon which is a zeroconf derivative in itself. If this process caused issues, isn't well maintained, and eats up precious resources then why is it being utilized in ROS? All the way to Hydro, I see zeroconf. I read the discription provided by the ROS wiki, and checked Archlinux for zeroconf and avahi. I still don't see what purpose it serves because I don't see it being a dependency for anything other than ros-hydro-turtlebot-bringup.
What purpose does zeroconf and avahi serve when the amount of resources it consumes is detrimental in a resource scarce scenario such as most robot systems, e.g. 7-DOF manipulators, vision-based path planning/navigation, etc?
I am trying to understand what, why, and how of this package/stack. I feel like it should be deprecated.

Hello,
I have some Javascript code that uses rosbridge_suite (Hydro debian install under Ubuntu 12.04) and roslibjs (latest version) to read in a parameter value from the rosbridge server and then set its value in a form field. It seems I don't understand the timing of when the parameter is read or the sequence in which Javascript functions are executed (or both) because I'm not getting the result I expected.
My code (included below) does the following:
sets a default value for the parameter
reads the parameter from the rosbridge server and, if not null, overrides the default value
sets the value of a form field to the parameter value
What I see on my form is that I always get the default value, not the value from the parameter server. If I put some log statements in my script, I see that the form value is getting updated before the parameter value is read via roslib even though the roslib code comes first. I am also verifying that the value is being read from the parameter server correctly.
Here now is the relevant snippet:
var maxLinearSpeed = 0.2;
// Create a Param object for the max linear speed
var maxLinearSpeedParam = new ROSLIB.Param({
ros : ros,
name : '/maxLinearSpeed'
});
// Get the value of the max linear speed paramater
maxLinearSpeedParam.get(function(value) {
if (value != null) {
maxLinearSpeed = value;
console.log(maxLinearSpeed);
}
});
var formElement = document.getElementById('maxLinearSpeedDisplay');
formElement.innerHTML = maxLinearSpeed;
So if I set the value of the maxLinearSpeed parameter to 0.5 on the rosbridge server, then run my script, I always see the default value of 0.2 in the form field labeled 'maxLinearSpeedDisplay' instead of 0.5 as I expected. Yet the statement console.log(value) above displays the correct value of 0.5.
Any idea what I am doing wrong?
Thanks,
patrick

Hello all,
I'm trying to read values from base_link frame in order to get my robot's coordinates with the following code:
tf::TransformListener listener;
tf::StampedTransform transform;
try {
listener.lookupTransform("/base_link", "/odom", ros::Time(0),
transform);
} catch (tf::TransformException ex) {
ROS_ERROR("%s", ex.what());
}
However, all I get is an error.
[ERROR] [1394401426.907398394,
36.516000000]: Frame id /base_link does not exist! Frames (1)
I can visualize base_link in rviz or read it's values on terminal using rostopic echo so I'm pretty sure it exists.
Any help is much appreciated.

Hi,
Which would be the recommended quadrotor for using hector_slam. I am currently trying the nicely documented tutorial : hector_quadrotor ( link ) . I was wondering on which all quadrotor everyone is using the hector_slam package.
While looking for this answer, I came across these links:
http://answers.ros.org/question/9101/which-quadrotor-has-the-best-ros-support/
http://answers.ros.org/question/12412/autonomously-flying-quadrotor/
http://wiki.ros.org/MikroKopter/Tutorials/shared_control
http://wiki.ros.org/Robots#UAVs
http://www.ros.org/news/robots/uavs/
I could not figure out which quadrotor was used for development and testing of Hector SLAM. So with my finding, my best option (might be only) would be Ascending Technologies Pelican. Has anyone tried using Hector SLAM on Pelican ?

Greetings!
I am soon starting up my new hobby project: a SLAM-robot with no clear goal yet (part from navigation). All the parts have arrived but I need some advice regarding what stack to start with, as I do not want to assemble all software components from scratch. I will start of by presenting the list of hardware.
CPU-board: Hardkernel ODROID-U3
Controller board: Arduino plug-in board for ODROID-U3
Motors: Two pretty fat stepper motors
Stepper motor drivers: Two L298N based stepper motor driver boards
Sensor: Microsoft Kinect
The robot will be assembled on a frame built of sheet aluminium together with a 360º turning nosewheel and airplane wheels for the stepper motors. The Kinect sensor will be mounted on the top of the aluframe.
Now there are several issues that I need to address and I hope that the ROS community can help me with some of them or at leaste provide som useful suggestions.
The ODROID officially supports releases of ubuntu 13.10 and up. As I understand the latest Ubuntu officially supported by ROS is 13.04. Obviously there is a gap here and I have the options of installing a non-supported OS on the ODROID, or compiling ROS from source - I am not very impressed by any of those two solutions. Another option is to run Android but I have a bad feeling about that since it seems very experimental.
I do not want to build my application from scratch as this is a waste of time imho. What I need to figure out is which pre-assembled stack to use in order to get as close as possible to my particular setup. I'd be happy if the only thing I'd actually need to implement in code is the stepper motor interface on the arduino.
What is the recommended workflow for developing the robot application? SSH in and have the build environment located on the ODROID? Cross compile on a PC?
Finally, I am interested in some cool applications for the robot. I.e. vacuum cleaner, spy etc.
Let's get this discussion started!

Hi everyone,
what do I have to do to add custom message types for use with rosmatlab by TU Darmstadt?
I tried to add a new directory called msg in workspace/src/rosmatlab/rosmatlab and placed a file called Num.msg inside of it. But examining the appropriate CMakeLists.txt file, I noticed all message being included with the function add_mex_messages followed by the message name in paranthesis.
So does anybody know how to solve this?
[Edit 2014-03-12]
Okay I now created a new package outside of the rosmatlab workspace and defined a new message type there. Then I compiled it to make it accessible by the ROS system itself. Then I added a add_mex_messages() statement to the CMakeLists.txt in the rosmatlab workspace and a <build_depend /> tag in the package.xml to refer to that package containing the new message type. When I compiled the rosmatlab workspace with these settings everything went well, until cmake claimed a non-existent header file referred to by the C-MEX file of my message type. In fact the header file doesn't exist at all and I'm wondering why it hasn't been generated by rosmatlab or whatever if everything else has been generated. I'm sorry, if it is obvious to all of you, but it is neither documented nor obvious to me, so if anyone has anything to say about this topic, please let me know! Thanks in advance.
Greets,
Roberto

Newbie warning. If this is a stupid question, please be patient. :-)
I have installed ROS Hydro. I have run through all the beginners tutorials ... so I have created publisher nodes, subscriber nodes, message types, services, and clients. I have also worked through most of the Gazebo tutorials, so I feel like I understand how to write software on my robot and how to test that software using the simulator. But I have not come across anything yet about human operator graphical interfaces.
What is the robot development community typically using to create their operator GUIs and how do those GUIs typically communicate with the robot? I have not found anything on this topic, so I'm assuming that there are no tools bundled with ROS to help me with this part of my robot software suite.
Any help is greatly appreciated. Thanks in advance.

When specifying the machine-tag for a ros-node in a launch-file one is principally able to run a ros-node on any reachable machine in the network that is configured for ros. Do I get this right? If yes, I am wondering about the following questions:
How does this work when I developped the code for my node on machine A and I execute it on machine B. Somehow, the binary must be transmitted, doesn't it?
What happens, if machine B contains a conflicting older version of the same node, which version will be executed?
Given the case that a team of programmers develops ros-nodes on different machines and all nodes are finally executed using a launch-file on another machine - let's name it master-machine - that runs the roscore:
Although they merge their changes using a VCS and this could theoretically be checkout and built on the master-machine in advance of every execution of the launch-file, is there a possibility to simply update the code on the master-machine (e.g. using roscp)?
(the wiki told me to include this: http://wiki.ros.org/ROS/Tutorials/MultipleMachines)

Is there a way to have catkin_make print all warnings? I am using Jenkins to test the builds of packages under Ubuntu 12.04 and ROS Hydro. I would like to track all the warnings from the packages and need to have those printed out. The best solution for me would be a command line argument rather than editing existing CMakeLists.txt files to add a definition for -Wall. I've found that the first time I build packages the warnings are printed but after the first build the warnings are suppressed.
I have looked at the output of catkin_make --help and none of the --cmake-args or --make-args seem to do what I want.

Comment by dornhege on 2014-03-10:
Do you want gmapping to use pitch/roll or do you want to get pitch/roll estimates out of gmapping. In either case: gmapping is set up to be a 2D algorithm.
Comment by Yuichi Chu on 2014-03-11:
I use gmapping to create 2D map.But the ground is not flat.So I think maybe I need to publish roll and pitch and I want gmapping to use the data.I am confused about whether I should use a node to publish roll/pitch in some format like message or I only need to add pitch/roll to TF frames.
Comment by Yuichi Chu on 2014-03-11:
In other word, how can I let the gmapping know that there is roll/pitch data to use?Thank dornhege for your attention.Would you give me some advices?

Hi,
I want to use dynamic_reconfigure in one of my nodes, however, one of my parameters is actually a variably-sized array of doubles. Can dynamic_reconfigure support variably-sized arrays, or does it only handle name-value pairs and structures?
Would a service with custom message type be a better solution for setting the array?
Thank you for your help.

It seems that my turtlebot is not working right with amcl. I don't know what it is. Rviz shows my map, and turtlebot, and even what I think is feedback from the laser. (There are colorful clouds of light around what I suspect is the solid objects in the lasers path). I can also use my '/initalpose' publishing node to publish a starting position for the robot. This seems to work. I can watch rviz and see the robot move to a new position (...if I publish to /initialpose repeatedly).
I cannot get any response when I send the robot goal coordinates. I have tried '/move_base_simple/goal' and I have written code that sends coordinates to '/move_base/goal', that code using the Move Base Action Subscribed Topic. For me nothing works. My thoughts are that maybe the robot isn't localizing for the first time when I tell it where it is. Maybe there's a setting in amcl that adjusts the level to which the room map must match the laser scan in order for the initial localisation to take. Could this be? Does anyone have any clues about this??
EDIT: Here's more info. this is my rapp interface file. Maybe I've messed that up.
publishers:
- scan
- /tf
- tf_changes
- /tf_changes
- map
- amcl_pose
- move_base/TrajectoryPlannerROS/global_plan
subscribers:
- mobile_base/commands/velocity
- initialpose
- /initialpose
- move_base_simple/goal
- /move_base_simple/goal
- move_base/goal
- /move_base/goal
- /move_base/goal/goal
services:
- save_map
- rename_map
- delete_map
- publish_map
- list_maps
I can also post rapp files and launch files. Looking at the interface file, I don't know when to include a leading '/' slash when identifying topics.

there is no error message on the laptop, and there's none on the computer on the robot, at least not a visible one. I looked in the .ros/log/ folder and under the topic 'app_manager-application-amcl' there was nothing. Is there somewhere else I should look?
Comment by Ken_in_JAPAN on 2014-04-03:
Your problem seems to be same as one I have experienced. In my case, the problem is to forget to write a IP_Address of workstation in /etc/hosts on my turtlebot2 PC. So, I could move my turtlebot2 with Rviz. That means turtlebot2 couldn't receive goal message without IP_Address of workstation.
Comment by jihoonl on 2014-04-03:
can you start app manager with --screen option? it should log out app manager output via terminal.

This question is related to http://answers.ros.org/question/64702/overlaying-multiple-catkin-devel-spaces-at-the-same-time/ but it seemed better to ask separately than to hijack that thread.
I'm using catkin as a build tool from source. Basically, I want to have a base workspace that just contains catkin so that I can chain workspaces from there by using the setup.bash file. However, every catkin package (including catkin itself) depends on catkin_pkg. Since we are using catkin_pkg from source as well, I was hoping to be able to manually point to the catkin_pkg python files while configuring the catkin workspace, and have those files available in chained workspaces as well.
I tried the following to "build" catkin:
export PYTHONPATH=/path_to_custom_install_dir_for/catkin_pkg/src:$PYTHONPATH
cmake .. (with appropriate build and install dirs set)
make
But, when I source the setup.bash file that is created, the PYTHONPATH only has catkin, not my custom path to catkin_pkg.
Am I misunderstanding what about "the environment in which it was created" is pulled in when sourcing the setup file? Or, is there a smarter way to set up catkin + catkin_pkg from source in user-space? (I don't want to install it via apt-get or pip).
EDIT based on comments below:
Say I have workspaces A, B, C.
Now I:
add catkin_pkg to my PYTHONPATH
source ws_A/devel/setup.bash (PYTHONPATH now has both catkin_pkg and the ws_A stuff)
build ws_B.
In a new terminal, I source ws_B/devel/setup.bash, and then try to build ws_C.
Should I expect to see catkin_pkg on the PYTHONPATH in the new terminal? I think that's what I'm doing now, but the catkin_pkg that was on the PYTHONPATH when building B doesn't get passed along through the setup.bash. It's fine if the answer is "that doesn't work", I just want to be sure before I pick a different design.

Comment by William on 2014-03-10:
That is the case, the PYTHONPATH will not be preserved by the setup file. The setup file will add any underlaid workspaces in your environment to your PYTHONPATH, but if catkin_pkg is not installed into one of these "underlays" then it will not get set by the generated setup files.

Is there anything in the logs that it mentions? Have you tried running the same command by hand?

Sorry, I couldn't understand, what do you mean by hand?
Comment by Mechatronics on 2014-03-10:
My updated code worked, But I couldn't find images, they are not in .ros
Comment by ahendrix on 2014-03-10:
Rather than running those commands as part of a launch file, try running each command via rosrun and examining the output.
Comment by Mechatronics on 2014-03-10:
I am following this tutorial
http://wiki.ros.org/rosbag/Tutorials/Exporting%20image%20and%20video%20data
Comment by ahendrix on 2014-03-10:
I suspect you're not seeing any images because there aren't any images in your bag file on the topic you've specified. You should be able to see which topics are in your bag file, what their types are, and how many messages were recorded on each topic by running rosbag info on your bag file.

Hi all,
I am fairly new to ROS and Gazebo and I apologize if this question seems easy in advance.
So, I basically want to implement a path planning algorithm by simulating a scenario in "ROS-Gazebo" and I am using "ROS Hydro-Gazebo 1.9" distributions. My algorithm assumes that the robot is omni-directional i.e., it can move in both x and y coordinates, independently. As I have found out, "pr2" and "care-o-bot" are two robots that offer omni-directional motion. The only feature that I need from them is the omni-directional wheels and other features such as laser, arm, etc. are not needed. I would also need to get the odometry data.
Problem: I am not aware of any control plugin or library to control and move the "pr2" in "ROS Hydro-Gazebo 1.9". I am able to bring up the "pr2" in "Gazebo" using "roslaunch" command. But I cannot control it and move it around. To give an idea of what I want, in another case I am able to control a pioneer2dx using a differential drive controller plugin (libgazebo_ros_diff_drive.so). I wonder if such a thing exists for "pr2". If not, is there any other solutions to my problem?
I would greatly appreciate any helps towards finding a solution for my problem.
Thanks,
Ali

Hello all,
I followed the tutorial on stage for simulating one robot but in the stage stack there is not such file as a stage.rviz. Only a stage.vcg which according to the error prompted is the old extension file.
Where can I find the stage.rviz I can't see to find it anywhere.
Second, I have a URDF file for my robot. How can I load it in Stage using Rviz ? I know that Rviz is going to use it if I launch joint_state_publisher and launch the robot_state_publisher node with my URDF in argument. But will it works if I use that command ?
roscd stage
rosrun rviz rviz -d `rospack find stage_ros`/rviz/stage.rviz
I would try it myself but I just can't find a stage.rviz to load and try for now. I just don't really quite see how to combine everything here. What I want to achieve is to use a stage world for the simulation in Rviz as I want to design a path finding robot. I just want to give him some sort of "world to play with".
Thanks a lot.

Hello to all!
A few months ago, I connected Arduino to ROS fuerte using rosserial without problems. However, now I'm trying to reproduce it in ROS groovy and I always get the same error.
I am working with Ubuntu 12.04, ROS Groovy, Arduino 1.0.5, rosserial-groovy-devel and both Arduino Uno and Arduino Mega.
I do these commands:
Window 1:
sudo ./Arduino/arduino
Open Hello World example.
Select Controller Arduino Uno/Mega.
Select Serial Port /dev/ttyACM0.
Load code.
Window 2:
roscore
Window 3:
sudo chmod a+rw /dev/ttyACM0
rosrun rosserial_python serial_node.py /dev/ttyACM0
And I get this error:
[INFO] [WallTime: 1394533587.406466] ROS Serial Python Node

REP 103 defines the standard for rotation representation as quaternions, but the covariance matrix associated to it is given in terms of fixed axis rotations. In my work, I use quaternions directly for attitude estimation and obtain covariances in terms of the quaternion parameters.
How can I convert these covariances to the convention used by ROS, so they can be published appropriately?
PS: I have searched ROS Answers and found a few discussions briefly addressing this topic, but usually referring to external documents or additional packages. I think it would be useful to have a single definitive reference for this here, so that implementations don't depend on the reader's interpretation of what is expected.

Hi,
I am using ROS hydro on Ubuntu 12.04.
After using the command "rosrun image_view extract_images _sec_per_frame:=0.01 image:={IMAGE_TOPIC_IN_BAGFILE}" I'm having an error when executing"ffmpeg -r -b -i frame%04d.jpg .avi" The thing is I am not seeing the sequence of images after I play the bagfile.I ran "rosbag info" to obtain the topic in the bag file but when I run "rosrun rqtgraph rqtgraph" the /extract_image frame node is there all by itself.
When I follow the tutorials on http://wiki.ros.org/rosbag/Tutorials/Exporting%20image%20and%20video%20data I get an error "[FATAL] [1394583654.335465840]: Error opening file: play".After replacing play by "--clock" or just removing "play" everything seemed to go just fine but there are no frames*.jpg in /home/.ros.
I feel like I'm lacking something.Can anyone help?

Hi all,
I am simulating gmapping in Gazebo with my Turtlebot. I have attached an Hokuyo laser on my (virtual) turtlebot and want to use this for gmapping instead of the virtual kinect laser.
The problem I have is that the virtual Hokuyo returns measurements at its maximum range. E.g. it would return a circle of measurment points of it would be placed in an empty world. Gmapping uses these measurements as if obstacles are detected there. This completely messes up the scan matching process, as it tries to match everything with the non-existent circular wall.
If I use the Hokuyo on my real robot, it only returns true measurements, i.e. if it cannot detect something at a certain angle, it will not return any data point (as if the distance seems infinite).
How should I adapt my virtual Hokuyo to not return data points when it has not detected anything at its max range?
Or alternatively, is there any way to adapt gmapping to cope with such measurements (which less elegant I think, as the difference between simulation and real experiments persists in other fields of measurement usage)?
Please see the screenshots attached: rviz clearly shows the 'circular non-existent' walls. I have only turned around in circles for this screenshot. If I would also move around with the robot, the scan-matching trouble becomes clear. I also have these issues (but to a lesser extend) when using it in a gazebo indoor building world (willowgarage world).
Gazebo world (with laser visualized):
rviz result:
Any help would be very much appreciated.
Regards,
Koen
UPDATE:
A slight addition to my comment on dornheges answer: the maxRange can probably better be omitted, as skipped/missing measurements lead to the conclusion that certain space is empty, although the robot cannot actually see this. See for example the explored space outside of the room in the screenshot... Clearly, the robot couldnt know this: it is based on the assumption that no measurment equals free space.
Does anybody know a nice way to still use this 'space is free if nothing is measured' feature, without running into this glitch (i.e. make it robust against skipped/missing/erroneous measurements)?

I'm trying to contribute a package to ROS. This is the error that jenkins.ros.org gave back:
/usr/bin/ld: cannot find -llapack
collect2: ld returned 1 exit status
I'm assuming that this is a dependency that needs to be added with a rosdep rule in the manifest. So, I've added the following line to package.xml:
Is this correct?

Hi all,
I wonder in which frame the interactive_marker.pose field is expressed? It seems relative to interactive_marker.header.frame_id but even considering that hypothesis, I get a strange behaviour. Let me explain...
I'm writing an application were several parts of furniture (leg, back of a chair...) are represented in RViz has interactive markers.
Each part is relative either to the world or to another part and all of them publish their transform with a TransformBroadcaster. view_frames gives:
view_frames result http://cjoint.com/14ma/DClneaiqh6K_view_frames.png
It seems that InteractiveMarker.pose designates the coordinates of the IM with respect to the frame InteractiveMarker.header.frame_id so when I set a new frame_id for an existing object I recompute the InteractiveMarker.pose with respect to the new frame_id, so that the pose doesn't move in the world frame. This works well, the new coordinates are computed with respect to the new frame thanks to a tfListener and there are correct.
When I move the parent frame with RViz, the child frame also moves because the pose of the child doesn't change with respect to the parent and this is exactly want I want.
Except that, when I click on the child object it's suddenly teleported elsewhere. I have disabled all callbacks for the Interactive Marker, so the server does that on its own But I don't know why. The transformation applied to the object is not random, it is exactly the transformation from its parent to the world.
Here is as exemple, I start with the interactive marker "leg1" at x=0 y=0 z=5 with respect to /world. I set it relative to /sitting which is at 0 0 -1 with respect to /world. The coordinates of "leg1" with respect to the world are computed by a tfListener and are 0 0 6, so I give these coordinates to leg1.pose.position = (0, 0, 6). Then when I click on "leg1" without moving it, it's teleported to 0 0 5 relative to /sitting, and if I click again 0 0 4, 0 0 3, and so on.
[ INFO] [1394553885.833971573]: leg1 is at 0 0 5 relative to /world
[ INFO] [1394553885.834646868]: [callback] leg1 set relative to sitting which is at 0 0 -1 relative to /world
[ INFO] [1394553885.848262357]: leg1 0 0 6 relative to /sitting
[ INFO] [1394553885.845737564]: [callback] leg1 is clicked (but not moved and no code is executed)
[ INFO] [1394553886.719846935]: leg1 0.10338 0.06199 6.96599 relative to /sitting (so almost 0 0 7)
It sounds like I forgot to set a "frame_id" somewhere to avoid the server to apply this automatic pose transformation. But I don't know where because if I server->get("leg1") the frame_id is actually set to "sitting".
I have been tearing my hear out on this issue for one week, but it's still unsolved and I don't know what to do with that :( I hope my explanations are understandable.
All clues are welcome, many thanks by advance for your help.

For our robot we had a Gazebo model built in SDF. The real robot has two unpowered omniwheels. In the SDF model, these omniwheels were modelled as a ball joint: a sphere with the radius of the omniwheel and two axes of rotation around the X and the Y axis. This worked perfectly and allowed the robot to move freely in simulation as it does on the real robot.
SInce we are now trying to integrate with MoveIt, the need has risen to use URDF instead of SDF. However, the revolute2 joint type is not supported by URDF, for reasons unclear to me. The alternative that is usually suggested is to use two chained revolute joints by the use of a virtual link.
First of all, the virtual link needs physical properties: if it does not have a part with a element, it will just be completely omitted by gzsdf. What physical properties can I attribute to a non-existing virtual joint?
Then, if I just make up some value for mass and set up the joint to have 2 chained axes of rotation, it kind-of works. But not completely, and not equal to how the revolute2 joint did. The problem is that whenever a movement is initiated in a direction that does not align with one of the two chained axes of the omniwheels, it will behave like a caster-wheel: it will move sideways a bit until it is in the appropriate orientation. This means unpredictable movement that does not occur on the real robot. This also did not occur when using the revolute2 joint types in Gazebo.
So now I'm stuck. I really do not feel like maintaining an SDF and an URDF version of the model. However, URDF seems to have discarded revolute2 as a valid joint type (even if it is directly supported by the SDF format to which it converts, which is the only thing that I want as the only thing that matters here is avoiding the friction or imbalance by fixing or leaving out the omniwheels).
One possible, but very complex method would be to make an accurate model of the omniwheels and add a separate joint for each roller. However, this would result in an additional 40 joints (2 2-layered wheels with 10 rollers) and I doubt this will be beneficial for the performance of Gazebo.
Any insights on how to fix this would be greatly appreciated.

Hello everyone,
I'm using ROS with a non-Ubuntu linux distribution and hit unexpected bugs quite regularly.
This is my newest discovery and it would be great to see this fixed one way or the other:
rosbuild automatically links all libraries of modules listed in manifest.xml to rosbuild targets.
This is obviously bloated, but it's fine in ubuntu, because they decided to make their gcc linker default to
--as-needed instead of the official --no-as-needed and only reachable libraries are actually linked.
Normally, this is not even a severe bug, but only adds more unwanted links.. However,
gazebo decided to add a /usr/lib/gazebo-X.Y/plugins/ folder for some of their libs and this folder is only
added to LD_LIBRARY_PATH when gazebo is actually used. In my case, we have a launch-file-only dependency
to gazebo. This adds a lot of gazebo libs to all binaries of the module, but doesn't add the gazebo environment at build time. Without --as-needed this produces a linking error because the gazebo libs require libs in gazebo's plugin folder.
Long story short(er):
It seems like at least rosbuild assumes that gcc uses --as-needed which is a non-official default.
Although I don't think these severe linking errors would appear with catkin, I'd say catkin assumes this as well
(and it does make sense to do that!). Otherwise people should probably be more careful when using
the catkin_LIBRARIES variable.
Is it possible to officially add this LDFLAG to the standard cmake framework for rosbuild/catkin?
-- EDIT --
I ask this question here instead of talking to a ROS package manager directly, because I got absolutely no idea
in which package this would have to be added. Any ideas?

Comment by ahendrix on 2014-03-11:
I'm confused; are you using rosbuild or catkin?
Comment by v4hn on 2014-03-11:
The module which produces the gazebo error I explained is based on rosbuild.
But the underlying problem of heavily overlinking things built within ROS also applies
to catkin. There, one uses catkin_LIBRARIES, which usually gives you more
than you need for a single target in a larger module.

Dear ROS Supporters,
Is there developer documentation for TCPROS connection header probe attribute for discovery?
Thanks,
Aaron
I believe probe was used by rossrv for introspecting service type information that is not available via the XMLRPC API. This made me wonder what else is not documented. I've been working on a Java client for over a year, and this sort of information would of been like gold. My client did discovery of service types via an auto-generated shell script that is not platform independent, and required the user to manually run the script, then import the discovered data to the client.
This data trace was performed in February 2014 on the latest version of ROS.
The changelist at the following URL mentioned the probe... http://wiki.ros.org/ROS/ChangeList/1.2
The following is the Hex of a Wireshark data trace:
410000000e000000736572766963653d2f737061776e0700000070726f62653d311400000063616c6c657269643d2f726f7373657276696365080000006d643573756d3d2a
The following is printable text of the above hex string:
service=/spawn
probe=1
callerid=/rosservice
md5sum=*

Hi!
I'm trying to to use threading in RosAria.cpp, but I need to compile the cpp file using:
"g++ thread.cpp -pthread -std=c++11 -Wl,--no-as-needed". How can I force rosmake to include the parameter "-pthread -std=c++11 -Wl,--no-as-needed" when compiling?
I need to thread this way because I'm using cin to ask for user input, and the other thread needs to check sensor inputs and control the robot based on this. Cin is blocking/waiting for user input and can therefore not run on the same thread AFAIK.

You could also create a client node that gets the user input and perform the control, rather than modifying the rosaria driver node.

Hi,
I'm using turtlebot on ROS electric on ubuntu 11.04.
The openni-dev package was recently updated from version 1.1.0.41~natty to 1.3.2.1-4~natty2.
After this update, the openni.launch process gives the error "No device connected.. Waiting for devices to be connected". Its not able to initialize.
I tried to downgrade the openni-dev version using the command:
"sudo apt-get install openni-dev=1.1.0.41~natty", but it says that the version was not found. I have also tried replacing the entries in the source.list files for apt to "old-releases.ubuntu.com", but it still didn't work.
Any help would be appreciated.
Thanks.

Hello all!
I am studying slam in a real indoor environment using a Pionner robot and a hokuyo laser. After getting a map i can see if the data association is correct or not but i would like to compare analitically the whole process. Gmapping has a publisher with the entropy over the robot pose. Does anyone do anything with the entropy? I´m trying to study the values of the entropy but it use to be constant.
In case i not use the entropy, is there an easy way to get values of the uncertainty of the position?
Thanks in advance
Regards

Hello all,
I have 2 robots erratic robots in gazebo and I want them to have approximately the same orientation. I am trying following piece of code but it doesn't seem to have any effect on my robot's rotation.
tf::TransformListener listener;
tf::StampedTransform transform;
try {
listener.waitForTransform("/odom", "/base_link", ros::Time(0),
ros::Duration(3.0));
listener.lookupTransform("/odom", "/base_link", ros::Time(0),

What do you mean "doesn't seem to be working"? Does it give a compilation error? Does the pose end up in the wrong place? How are you sending these transforms to gazebo?
Comment by SpiderRico on 2014-03-12:
Updated my question. Hope it's more clear now.
Comment by atp on 2014-03-12:
I think that you have to broadcast the transform again. Have a look at the "Writing a tf broadcaster" tutorial.

Hello. I'm now working on navigation stack in hydro. I want to use a global costmap to implement a new algorithm for path planning. So I created a node and subscribe to /move_base/global_costmap/costmap which is nav_msgs::OccupancyGrid type. The problem is this node receive costmap only one time when it come up and never update. In rviz everything is fine. Any idea ?

I'm trying to understand the whole velodyne_driver package and I have several doubts.
I configure the network, connect the Velodyne and I check the data and I I see everything is well connected and configured (using rviz):
roslaunch velodyne_pointcloud 32e_points.launch calibration:=/home/user/32db.yaml
rostopic echo /Velodyne_points
But if I run: velodyne_node, I see it is publishing in /velodyne_packets but I can not see the data because I get an error.
rosrun velodyne_driver velodyne_node _model:=32E
rostopic echo /velodyne_packets
Traceback (most recent call last):
File "/opt/ros/groovy/bin/rostopic", line 35, in
rostopic.rostopicmain()
...
IOError: [Errno 13] Permission denied: '/home/vplaza/.ros/rosdep/sources.cache/index'
1. Is it normal not seeing this data with rostopic echo? Is it because /velodyne_packets is an structure instead of integer values as /velodyne_points ? Is it because /home/vplaza/.ros/ does not exist?
Some rostopic works fine:
rostopic bw /velodyne_packets
rostopic hz /diagnostic
But this one returns the same error as before:
rostopic hz /velodyne_packets
2. Is this error normal in /velodyne_packets?
If I try to change the speed of the Velodyne I dont see the device is changing. I have try with 300 rpm and 10 rpm:
rosrun velodyne_driver velodyne_node _model:=32E _rpm:=300
3. What can I do to change the velocity?
Then I try to execute a velodyne test but I get an error:
rostest velodyne_driver pcap_32e_node_hertz.test
... logging to /home/vplaza/.ros/log/rostest-vplaza-PClinux-6466.log

IOError: cannot create test results directory [/home/vplaza/.ros/test_results/velodyne_driver]. Please check permissions.
4. How should I run the test? Is it because /home/vplaza/.ros/ does not exist?
And also the manual "velodyne_driver" said the driverNodelet does the same process as the node velodyne_node.
5. What's the difference between the node and the nodelet? The topic published is the same /velodyne_packets.
6. If the nodelet is executed with roslaunch with the file nodelet_manager.launch , why the nodelet_velodyne.xml (linked in manifest.xml) shows the file lib > libdriver_nodelet.so instead of the launch file? How does it works?

Hi,
I would like to ask if anyone has got to get the PrimeSense RD1.09 RGBD camera working with ROS when connected to a USB 3.0 port under Ubuntu. Right now I am using ROS Fuerte, Ubuntu 12.04.3 (Kernel 3.8.0-31) but cannot get the camera working on the USB 3.0 port (it does work when plugged into a USB 2.0 port). The camera is correctly recognised if I do lsusb. However, it shows the following error message when executing roslaunch openni_launch openni.launch:

I've got almost the same setup, but using openni2_camera: https://github.com/ros-drivers/openni2_camera
It works mostly like openni_camera, so try that and see if it does the right thing.
Comment by Tinrik on 2014-03-12:
I'm absolutely new to ROS and I only know basically how to use openni_launch, nothing else. I have also installed hydro which comes with openni2-camera. Could you please tell me the commands to use openni2_camera? Thanks :)

?- visualisation_canvas(_).
lights() is not available with this renderer.

How can I improve odom of a robot by a laserscan- what package can i use?I don't have static, global map. I found laser_scan_matcher, but I don't know if it's still supported.
Maybe i should play with dynamic costmap and amcl? or maybe there is sth better?
Thanks in advance

AMCL needs a static map to match against. I've not used laser_scan_matcher but it does look promising, and there's a hydro branch in the source repo. Is using a laser scanner your only option for improving odometry?
Comment by BP on 2014-03-12:
I think it is this option, but maybe i am wrong. What kind of improvement there exist (i know about IMU and this laser-scan-mach)
Comment by jbinney on 2014-03-13:
If you have a cmaera, visual odometry is pretty common (track visual features using cameras). Here's a ROS package that does visual odometry: http://wiki.ros.org/viso2_ros

I've been trying to build ROS Hydro from source on my laptop, running Ubuntu 13.10. However, I keep running into a compile error with openGL.

make: *** No targets specified and no makefile found. Stop.
I've looked up the issue in a more general scope, not focused on ROS, and most of the solutions involved adding a missing symlink (though the most recent posts about a failure to compile with libGLU.so are dealing with Ubuntu 11, so it's not exactly up-to-date), but checking the file locations themselves showed that the symlinks were all there. I also tried purging and reinstalling the openGL drivers, which resulted in the same error.
Thanks!

Edit2: just realized that last time I raised a ticket in github against camera_info_manager, but then the issue got resolved on its own, so I just reopen the ticket. See make verbose output on the link: https://github.com/ros-perception/image_common/issues/23

It looks like camera_info_manager tries to link against camera_calibration parsers: https://github.com/ros-perception/image_common/blob/hydro-devel/camera_info_manager/CMakeLists.txt#L23
Can you add a "message()" to the cmake lists to check the value of ${camera_calibration_parsers_LIBRARIES}?

Another questions is how to use the camera driver to auto configure the image effect when the light / exposure changes? for example, in sunlight and in shade. like when in sunlight, the light gain will be decreased and in the shade, the light gain will be increased

In Hydro, I create a launch file with the following to get data from my attached Kinect:
It publishes a lot of stuff but not "/camera/depth_registered/image_rect". This worked fine with Groovy.

Hello,
Could somebody tell me how could I install the smash-viewer package in ROS-Hydro, please.
I though that the package should be already in the las distribution but I have just installed Hydro full desktop and it isn't there.
I also tried apt-get install ros-hydro-smach-viewer and nothing
Thanks in advance,

Hello,
I know for I have find a question answered where someone was able to make two different version of ROS to communicate with each other. I can't seem to find the question again though.
My computer runs groovy and I have a Pie with Fuerte on it. I'm wondering to which extent I can make then work together as I would like to use my computer for simulation and the Pie on the robot.
If you ask I already tried to install groovy on Raspbian and it fails for libboost being a problem during the ROS install. I'll be willing to try to install groovy again or install Hydro as well if the communication between Groovy and Hydro is better.
Thanks

I launched amcl with turtlebot2, but turtlebot2 doesn't move. I have installed ROS hydro on my PC. When I launched amcl on groovy, my turtlebot2 moved correctly. I checked some topic with rostopic echo command.
/navigation_velocity_smoother/raw_cmd_vel and /cmd_vel_mux/input/navi don't respond.
/move_base_simple/goal outputs values.
/mobile_base/commands/velocity outputs values when I touched bumper sensor.
I launched a following command.
roslaunch turtlebot_bringup minimal.launch (on turtlebot PC)
ssh turtlebot@turtlebot(on workstation)
roslaunch turtlebot_navigation amcl_demo.launch map_file:=/tmp/my_map.yaml(on workstation set to point to turtlebot PC)
roslaunch turtlebot_rviz_launchers view_navigation.launch(on workstation PC)
It has a warn.
[Warn] Waiting on transform from base_footprint to map to become available before running costmap, tf error:
if anybody correctly moves a turtlebot on hydro, I want you to teach me how to move.
and I want any clue to solve this problem.

This alarm was described on costmap_2d_ros.cpp. So, I added footprint to costmap_common_param.yaml.

@Ken_in_JAPAN For the next time, better post additional information by editing your initial question instead of multiple comments (hard to read).

Hi,
we would like to simplify the dependencies installation process using rosdep. It deals easily with debian packages but we would like to use source code from svn too.
In the answer 74404 says that "rosdep is not designed to pull packages from source" but we found ROSAria's libaria.rdmanifest and how they do that, even though it's a bit tricky, we have found a way to use svn. Anyway,
Is there a way to add svn dependencies a bit more cleanly?
We have found out that a tar.gz file is needed in "uri:", how can we get rid of it?
Thanks in advance!

Hello,
I have a package that I'm developing in my computer using catkin workspace. To test some network issues, I need run a node from this package in other machines. I read the tutorial "Running ROS across multiple machines" but I don't know how deploy or copy my package to the remote machine. The tutorial uses a "pre-instaled" package (rospy_tutorials). I think it's a common task and should be simple to do.
Thanks

Let's assume I have class cA, which has a node that subscribe from topic and publisher with a "constant" frequency. Class cA is a mamber of class cB.
Where I should put "while(ros::ok())" for publishing purpose? Cose if i put it in constructor it'll bloc constructor of "higher" class (ofc. I can make a function cA::Publish() and run everything further in cB::Publish() or split classes to more nodes and classes, but i am looking for beter solution).
Should I use threads? I have never used them so I don't know if i should. I found this
cant_post_links_http://wiki.ros.org/roscpp/Overview/Callbacks%20and%20Spinning
Is there an easy example?
thanks in advance

I'm trying to launch the navigation stack for the pr2. Here's what I run:
rosrun map_server map_server basement_map.yaml
roslaunch pr2_navigation_global rviz_move_base.launch
(on the robot) roslaunch pr2_2dnav pr2_2dnav.launch
After I launch the 2dnav on the robot, the robot model appears in rviz. After about 10 seconds the red markers for obstacles appear and rviz crashes immediately. Usually it doesn't give an error message but sometimes there's also this message:
*** glibc detected *** /opt/ros/groovy/lib/rviz/rviz: free(): corrupted unsorted chunks: 0x000000000280e750 ***
======= Backtrace: =========
/lib/x86_64-linux-gnu/libc.so.6(+0x7eb96)[0x7fd273539b96]
/opt/ros/groovy
(there's a lot more text, here's the full error message: pastebin.com/ArwKkirr)
Sometimes the message looks similar, but starts with "corrupted double linked list" or "malloc error".
The same thing happens if I launch pr2_interactive_manipulation with navigation enabled (without navigation everything is fine).
I'm using Ubuntu 12.04, Nvidia driver 331 (I also tried it with 304 and with a generic driver, same thing happens).
Update: seems that the problem is caused by GridCells visualization. If I start with a fresh rviz ("rosrun rviz rviz") and add navigation-related topics one by one, rviz crashes after GridCells are added with a non-empty topic (for example, "/move_base_node/local_costmap/obstacles")
Update 2: Another way for rviz to crash turned out to be adding DepthCloud with a non-empty DepthMap topic (for example, "/head_mount_kinect/depth_registered/image").

Comment by demmeln on 2014-04-04:
Just a longshot: are you possibly mixing different ROS versions? Or different versions of boost? Otherwise, could be a bug in the GridCells display and it might be worth filing a bug report.
Comment by sonyaa on 2014-04-04:
Thanks for the suggestion! The versions of ROS and boost are the same on the robot and the machine I'm running rviz from. I've also just discovered one more way to make rviz crash (see update).

I would like to try running a CNC mill using ROS. More specifically I want to use RVIZ to help us visualize a CNC task prior to running it live on the CNC. My understanding is that one of the first step in this process is exporting my robot URDF using the SolidWorks URDF exporter. The exporter seems geared towards exporting revolute joints but doesn't seem to have any functionality to setup linear actuators / prismatic joints. Is this possible? If so what are the steps for specifying a linear actuator? If someone can point me the way I would love to write a tutorial about this.
Here are a couple of example 3 axis gantries that use linear actuators similar to the one I am working with:
GrabCAD: http://grabcad.com/library/damki-cnc-router-1
ShapeOKO: http://3dwarehouse.sketchup.com/model.html?id=f6ed9052b5de9a00dbd8f267ad6945df

Not really an answer, but AFAIK the exporter should support setting up prismatic joints. Not sure about the quality / correctness of the exported URDF then though.

Hi there,
I have installed ros-fuerte-desktop-full. I am trying to built a package that contains opencv code, but I am getting the following error:
Cannot specify link libraries for target "MatObjects" which is not built by this project.
I have added following to CMakeLists.txt
FIND_PACKAGE( OpenCV REQUIRED )
target_link_libraries(MatObjects ${OpenCV_LIBS})
Here is the output of some flags:

I have written a code to subscribe to the /camera/depth_registered/points topic to receive point cloud data from the kinect and then display it on a pcl::visualization::PCLVisualizer viewer.
The problem is that, while successfully subscribed to the topic (as proven using the rostopic info command), the callback function is not actually being executed. I know this because, at the very beginning of the function, I've added a simple print statement confirming, "Entering callback." This statement is never printed. In fact, the while loop (see below) is never exited i.e. the boolean new_cloud_available_flag is never set to true.
Here is the relevant section of the code:
//Including all possible libraries

// PCL viewer //

bool new_cloud_available_flag;
enum { COLS = 640, ROWS = 480 };
PointCloudT::Ptr cloud(new PointCloudT);
void callback(const sensor_msgs::PointCloud2ConstPtr& msg){
std::cout << "Entering callback";
cloud_mutex.lock();
sensor_msgs::PointCloud2 msg0 = *msg; //Changing pointer to actual cloud object
PointCloudT cloud0;
pcl::fromROSMsg(msg0, cloud0); //Converting sensor_msgs::PointCloud2 to PointCloudT
*cloud = cloud0;
new_cloud_available_flag = true;
std::cout << "Converted" << endl;
cloud_mutex.unlock();
}
int main (int argc, char** argv)
{
ros::init(argc, argv, "subscriber_node");
ros::NodeHandle n;
new_cloud_available_flag = false;
ros::Subscriber sub = n.subscribe<sensor_msgs::PointCloud2>("/camera/depth_registered/points", 1000, callback);
// Subscribe to kinect:
std::cout<<"initiate reading\n";
ros::Subscriber sub = n.subscribe<sensor_msgs::PointCloud2>("/camera/depth_registered/points", 50, callback);
// Wait for the first frame:

ros::Time t0 = ros::Time::now();
while(ros::Time::now()-t0 < ros::Duration(0.001));
std::cout<<"waiting for first frame\n";
}
std::cout<<"got first frame\n";

I have two classes, image publisher and image processor. Both classes start internal boost::threads for camera and sensor drivers, image processing worker threads. Both classes take long in their constructor, initializing cameras, sensor (RIIA -> image publisher), self calibration, initializing GPU (image processor).
Both run nice and smooth if they are in separate nodes, where the main just calls ros::init, creates a boost::shared_ptr with class instance, and then ros::spin()s:
int main( int argc, char** argv )
{
ros::init( argc, argv, "name" )
boost::shared_ptr<ImageProcessor> lp_proc = boost::shared_ptr<ImageProcessor>( new ImageProcessor() );
ros::spin();
return 0;
}
Again everything runs nice and smooth in nodes. But both classes heavily interact (exchanging images at 100 Hz) so I'd like to put them in nodelets. I just added an boost::shared pointer to the inheriting class and create the instance in onInit() look like:
class MyNodeletClass : public nodelet::Nodelet
{
private:
boost::shared_ptr<ImageProcessor> lp_proc;
public:
virtual void onInit()
{
lp_proc = boost::shared_ptr<ImageProcessor>( new ImageProcessor() );
}
};
However, if in a nodelet the nodes occasionally crash with memory corruptions, failed service calls, etc. Is there something to be very aware of when putting nodes in nodelets? Or maybe is there a timeout for the onInit until which a nodelet after loading has to get responsive? Might be a problem as my constructors occasionally take quite long?

Hi everyone.
I sincerely apologize if my question sounds stupid or has been answered before (I searched the forum and have read the tutorials but didn't find my answer). I'm currently building a URDF file for our robot using xacro. What I've noticed is that the origin of the frame of reference of every link is in the center of that link. For example when modeling hands, the tf will point to the center of the hand. I wanted to change this so tf frames will represent joints of hands and other parts of the robot, and not the middle of link. How is that possible to do?
Btw the current robot model is:

I am using the app_manager and three rapps. In one, the navigate rapp, I get this message when I try to use a service of my own.
[ERROR] [WallTime: 1394827317.221882] [Client 0] [id: call_service:/app_manager/application/load_map_db:7] call_service InvalidServiceException: Service /app_manager/application/load_map_db does not exist
why would the app manager tell me that this is non existant? I am running hydro on a ubuntu 12.04 system. I'm pretty sure it's there, in the srv folder there's a MapPublish.srv file, and in CMakeLists.txt there's an entry for the srevice in the 'add_service_files' section. Everything compiles right. Other services that Ive written work. What have I done wrong? I thought it was some kind of naming problem, but I think the names I've chosen are somewhat original. Any help would be appreciated. I can add more info if requested.
EDIT 1: My project works like this: I have a turtlebot and I use an internet service to transmit direction info from one computer to another, then through the chrome web browser, websockets and rosbridge server to the turtlebot. I have several services that I've authored that help me out. So far that works. I have also tried to implement amcl and gmapping functions that I try to start and stop remotely. I use the app_manager and three rapps. One rapp is for teleop, one for gmapping, and one for amcl.
I should provide documents showing some of these functions, but the idea is that the rosbridge server stuff tells the app_manager stuff to start and stop different launch files, allowing for this different functionality. This is why my service 'load_map_db' is preceded by the '/app_manager/application/'. What I don't do, is use the rocon launcher. Everything runs on the same port and there's no need to switch (I think they call it flip) from one port to another. I do use the app_manager 'start_app' and 'stop_app'.
I thought briefly that the rosbridge server didn't know about the app_manager navigation services because they weren't started when the rosbridge server was started. This didn't pan out. I restarted the rosbridge server stuff as well as I could in javascript at the time that the load_map_db service was used and there was no change.
I don't understand how some of the services work (like 'list_maps') but this one doesn't. Long ago you could have inserted a control character into a file or file name and not know it. Maybe I have done this? I suspect today's text editors will not let you do this. Below I include some source material.
This is my launch file for the whole program:
<launch>
<arg name="rapp_lists" default="tele_presence/tele_presence_apps.rapps"/>
<include file="$(find tele_presence)/launch/includes/app_manager_rocon.launch.xml">
<arg name="rapp_lists" value="$(arg rapp_lists)" />
</include>
<include file="$(find rosbridge_server)/launch/rosbridge_websocket.launch"/>
</launch>
This is my rapps file:
apps:
- tele_presence/mapping
- tele_presence/navigate
- tele_presence/teleop
This is the interface file for 'navigate':
publishers:
- scan
- /tf
- tf_changes
- /tf_changes
- map
- amcl_pose
- move_base/TrajectoryPlannerROS/global_plan
subscribers:
- mobile_base/commands/velocity
- initialpose
- /initialpose
- move_base_simple/goal
- /move_base_simple/goal
- move_base/goal
- /move_base/goal
- /move_base/goal/goal
services:
- save_map
- rename_map
- delete_map
- load_map_db
- list_map
EDIT 2: Some python:
def init_fn():
global client, db, collection, grid, map_pub, meta_pub
rospy.init_node('turtlebot_db', anonymous=True)
map_pub = rospy.Publisher('map', OccupancyGrid, latch=True)
meta_pub = rospy.Publisher('map_metadata', MapMetaData, latch=True)
rospy.Service('load_map_db', MapPublish, map_load)
rospy.spin()
def map_load(req):
#
global map_pub, meta_pub
#
whole_map = MapWithMetaData()
whole_map = collection.find_one({ 'info.map_id' : req.map_id })
if whole_map == None :
return ['badmap']
##
## SOME BORING STUFF HERE...
##
map_pub.publish(oldmap)
meta_pub.publish(oldmap.info)
#
return ['done']

Should I add that I am using ROSBRIDGE SERVER? Does anyone follow questions about rosbridge server? I am using v.2, and the tutorial at this site: http://wiki.ros.org/roslibjs/Tutorials/BasicRosFunctionality
Comment by Daniel Stonier on 2014-03-15:
That's a runtime error. Probably it built the .srv quite fine, but the error message there is saying the runtime service does not exist at /app_manager/application/load_map_db does. Use rosservice list to figure out where your service is, or backtrack to figure out why your service did not start
Comment by Daniel Stonier on 2014-03-15:
You might want to add more info about how you're using the rosbridge server. Hard to say whether it is relevant or not given just that information.
Comment by david.c.liebman on 2014-03-17:
I have added my python (which may be the problem) to the original question.
Comment by Daniel Stonier on 2014-03-17:
Is it a case of not having used wait_for_service before calling the service?
Comment by david.c.liebman on 2014-03-18:
how does one 'wait_for_service' with rosbridge server? I googled to no avail.
Comment by jihoonl on 2014-03-18:
hm... seems like wait for service is not supported by roslibjs and rosbridge yet. I have opened an issue in roslibjs repo. We can continue to discuss there.
https://github.com/RobotWebTools/roslibjs/issues/70
Comment by Daniel Stonier on 2014-03-18:
You could probably verify that it is indeed the problem by just putting a sleep of some sorts in your program for n seconds before calling the service. If there's no error, then you know it's just your service client calling the server before it's been constructed on the other side.
Comment by david.c.liebman on 2014-03-19:
yes, in fact a ten sec wait removed the error. (on two tests so far.)
Comment by Daniel Stonier on 2014-03-19:
aha, bingo :)

I am trying to follow the urdf parser tutorial.
My testbot_description package has a /src/parser.cpp file and a /urdf/my_robot.urdf file
Both are identical to the ones suggested by the tutorial page. (I already copied and pasted the code to make sure).
This is my CMakeLists:
cmake_minimum_required(VERSION 2.8.3)
project(testbot_description)
## Find catkin macros and libraries
## if COMPONENTS list like find_package(catkin REQUIRED COMPONENTS xyz)
## is used, also find other catkin packages
find_package(catkin REQUIRED COMPONENTS urdf)
## DEPENDS: system dependencies of this project that dependent projects also need
catkin_package(
# INCLUDE_DIRS include
# LIBRARIES testbot_description
# CATKIN_DEPENDS urdf
# DEPENDS system_lib
)
include_directories(
${catkin_INCLUDE_DIRS}
)
add_executable(parser src/parser.cpp)
target_link_libraries(parser ${catkin_LIBRARIES})
And this is my package.xml:
<package>
<name>testbot_description</name>
<version>0.0.1</version>

Thanks, BennyRe. I just added it. I hope it will help.
Comment by Joao Ferreira on 2014-03-15:
I just realized that when I comment the code that calls for initFile() I get rid of this error and I am able to build my package.
In my parser.cpp , if I keep the
"
if (!model.initFile(urdf_file))
{
ROS_ERROR("Failed to parse urdf file");
return -1;
}
"
the error appears again.

Hi, i am sonny..i am currently working on arduino and with that i am trying to install ROS. While i am trying to run my first basic code on arduino with ROS, the Hello world code in the ros_lib, i am getting an error like below..
In file included from /opt/ros/hydro/include/ros/node_handle.h:31,
from /home/traininghes/arduino-1.5.2/libraries/ros_lib/ros.h:38,
from HelloWorld.pde:6:
/opt/ros/hydro/include/ros/forwards.h:37: fatal error: boost/shared_ptr.hpp: No such file or directory
compilation terminated.
i am unable to verify the code since i don't understand the error.
It will be appreciated if someone please look at this issue and help me to get out of this problem.
Thanks..

Hello,
for some reason I'm unable to install this package, I'm using this command:
sudo apt-get install -y ros-hydro-visp-tracker
and this is the error I'm getting:

What is the error message ? And just in case you misspelled "hydro"

You should edit your question to add that kind of information. It'll be easier for everyone.

thanks, but do you have any idea how to solve the problem ?

It could be that I'm missing something, but does anyone know how to delete an attachment from a wiki page? Clicking the del link on the attachment page of the wiki page takes me back to the wiki page itself with an error admonition at the top stating:
Please use the interactive user interface to use action AttachFile.del!
Clear message
I've found some posts to the moin-user list mentioning this same error message [1], but no solution / work-around I can use.
Any ideas?

I've encountered this error building ROS on OSX. As far as I can figure, this started happening after I upgraded my developer tools to the latest version (5.1):
/usr/local/include/boost/atomic/detail/gcc-atomic.hpp:961:64: error: no matching
constructor for initialization of 'storage_type' (aka
'boost::atomics::detail::storage128_type')
explicit base_atomic(value_type const& v) BOOST_NOEXCEPT : v_(0)
^ ~
/usr/local/include/boost/atomic/detail/gcc-atomic.hpp:932:28: note: candidate
constructor (the implicit copy constructor) not viable: no known
conversion from 'int' to 'const boost::atomics::detail::storage128_type'
for 1st argument
struct BOOST_ALIGNMENT(16) storage128_type
^
/usr/local/include/boost/atomic/detail/gcc-atomic.hpp:932:28: note: candidate
constructor (the implicit default constructor) not viable: requires 0
arguments, but 1 was provided
It looks like this is problem with some of the dependencies for TF or TF2, and is causing a large number of things to fail to build properly.

Hi,
I have installed ros-fuerte-desktop-full and with it opencv got installed. Opencv code is working inside any ros package that I create. However, some times I like to work outside ROS and have Geany installed. I have given the following set build command to geany for compilation
g++ "%f" `pkg-config --cflags --libs opencv` -o "%e"
When I try to build it says:
Package opencv was not found in the pkg-config search path. Perhaps you should add the directory containing `opencv.pc' to the PKG_CONFIG_PATH environment variable. No package 'opencv' found.
My PKG_CONFIG_PATH already contains opencv.pc file. Here is the output of some flags:
#echo $PKG_CONFIG_PATH
/opt/ros/fuerte/lib/pkgconfig: //this path contains opencv.pc
#pkg-config --cflags --libs opencv
-I/opt/ros/fuerte/include/opencv -I/opt/ros/fuerte/include -L/opt/ros/fuerte/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_ts -lopencv_video -lopencv_videostab
#pkg-config --libs opencv
-L/opt/ros/fuerte/lib -lopencv_calib3d -lopencv_contrib -lopencv_core -lopencv_features2d -lopencv_flann -lopencv_gpu -lopencv_highgui -lopencv_imgproc -lopencv_legacy -lopencv_ml -lopencv_nonfree -lopencv_objdetect -lopencv_photo -lopencv_stitching -lopencv_ts -lopencv_video -lopencv_videostab
Any help would be greatly appreciated.
