Thanks a lot for fixing it!

I agree with @ahendrix :)

All,

I would like to add a custom scene to moveit using my own stl file. Is there any documentation on how that works? The only information I found is this. It works as described but when I try to import a stl file I exported from Solidworks, I receive an error saying: unable to import scene

Assimp reports no scene in file:///home/asdf.stl

I looked at the box.stl and it says it was exported using blender but I would like to use Solidworks :(

Any help is appreciated.

Hi all,

I got my own robot into moveit! and added a planar virtual joint between my robots' base_link and odom like described in the PR2 tutorial. I created a group called 'complete' containing this virtual joint and the arm and would like moveit! to plan the driving path as well as the arm joints. When I start moveit! it outputs this error in the terminal

[ERROR] [1364401925.457291185]: Could not initialize chain object [ERROR] [1364401925.457352872]: Kinematics solver of type 'kdl_kinematics_plugin/KDLKinematicsPlugin' could not be initialized for group 'complete'

When I choose 'complete' as planning group in rviz and set the start state to random and press 'Plan and Execute" it works as desired and I can see it move to the goal state. My problem is that the interactive markers appear at the base_link and not the gripper which I think is due to the error posted above. If I use a planning group without the virtual joint, the markers appear at the correct position but moveit does not plan the driving path for obvious reasons.

Any ideas?

Thanks a lot

I followed the tutorial about Segmentation in PCL and wondered what setOptimizeCoefficients does. In the tutorial the only comment is that it is optional and in the documentation I am told to set this parameter if a coefficient refinement is required. I am still not really what that is supposed to mean. Can anybody explain that to me?

Thanks in advance

Hi,

I am using pcd_to_pointcloud from perception_pcl and want to remap the output using a launch file. The problem is that it requires a pcd file as a command line argument which I do not get to work using a launch file. Is there an easy way or should I issue a pull request for a modified node which can also read a pcd file path from a parameter.

Hello world,

I am trying to compile the turtlebot software from source on my gumstix. I do not really have a problem with it, I just want to know if I am doing it the right way, because it is a very slow way. I manually scroll through the dependencies for turtlebot, locate the source and check if I can compile it with catkin. Then I add it to wstool, download the source and catkin_make it. Since compiling on the gumstix is really slow, I am not done yet, but I would like to know if there is a smarter way. Maybe a way to resolve all dependencies and find out which sources are catkinized and which have to be built in the rosbuild workspace? I also did not get PCL to compile :(

Thanks a lot in advance

Hi,

I am trying to install pcl_ros from source on a raspberry pi running groovy. I get this undefined reference when it tries to link bag_to_pcd

according to the PCL forum an undefined reference to pcl::PCDWriter::write means that I did not link against libpcl_io.so

I checked the CMakeLists and it does link against it, so I do not know what the problem is. It would be great if anyone can help

All, I installed ROS at least 4 times from source on different devices over the last month. I still do not really understand the structure behind this procedure. Let's say I want to build the desktop package from source. I would have to initialize wstool using http://packages.ros.org/web/rosinstall/generate/raw/groovy/desktop Then I call rosdep to have all dependencies installed and call catkin_make after that. What I do not see is why OpenCV2 and PCL are downloaded into the src folder and compiled using catkin_make and are not installed with rosdep using prebuilt binaries. Especially when you build on embedded devices, those huge libraries consume a lot of time and space to compile. If there is a reason, please let me know
