I would like to start with moveit_setup_assistant

roslaunch moveit_setup_assistant setup_assistant.launch

1, I have roscd to the moveit_setup_assistant pakage,

but fail to roslaunch .

(at that time ,echo $ROS_PACKAGE_PATH  ---> /root/catkin_ws/src:/opt/ros/indigo/share:/opt/ros/indigo/stacks
)

2, if I do:

 source /opt/ros/indigo/setup.bash

(at that time ,echo $ROS_PACKAGE_PATH  ---> /opt/ros/indigo/share:/opt/ros/indigo/stacks)

then, roslaunch succeeds!

but if I load the urdf file in my workspace( I follow the ros-by-example-2 in Chapter 11), The weird part is, the pi_robot I would like to load just shows the two wheels in the setup_assistant window, it seems that it cannot find my own package Here is the part of error message

"[rospack] Error: package 'rbx2_description' not found
[librospack]: error while executing command"

NOTE:

1, I have add this

source ~/catkin_ws/devel/setup.bash
source /opt/ros/indigo/setup.bash

to the bottom of the ~/.bashrc and I have source ~/.bashrc after this so that when I echo $ROS_PACKAGE_PATH,the result is what I mentioned in the statement 1 above.

2, Below is the error message for 1st statement,

root@ShawnVM:~/catkin_ws/src/moveit_setup_assistant# roslaunch moveit_setup_assistant setup_assistant.launch

3, I wonder if there is something wrong due to using VM? Something wrong with OpenGL driver?

rospack find moveit_setup_assistant

From the error messages you've posted, this is unrelated to you using a VM. Either the nodes (binaries) are really not there, or the search path is not configured correctly.

If you really must build MoveIt from sources, please remember to run

source $HOME/catkin_ws/devel/setup.bash

before trying to

roslaunch moveit_setup_assistant setup_assistant.launch

Note that you'll have to do this every time you open a new terminal (unless you add it to your .bashrc).


Edit:

I have add this

source ~/catkin_ws/devel/setup.bash
source /opt/ros/indigo/setup.bash

to the bottom of the ~/.bashrc But it does not work.

as @mpjansen correctly notes: you generally only want to source a single setup.bash. In this case, source the setup.bash of your own workspace, not the one in /opt/ros/$distro.

And a bit pedantic, but the source-ing probably works fine. Those two lines just don't do what you are expecting them to do (ie: cumulatively add to your ROS package path).


Edit2:

I have done what you said, only

source ~/catkin_ws/devel/setup.bash

And try again, yet it turns out that

ERROR: cannot launch node of type [moveit_setup_assistant/moveit_setup_assistant]: can't locate node [moveit_setup_assistant] in package [moveit_setup_assistant]

To avoid a lengthy process of trying to find out what causes this: can you please make sure you absolutely need to build MoveIt from sources? If not, please install the binary packages (sudo apt-get install ros-indigo-moveit-X), as that will make things a lot easier.

If you do need MoveIt from sources, please tell us exactly how you created, populated and built your workspace.

Also: what is the output of rospack find moveit_setup_assistant, after you have sourced your workspace?

And (to get it out of the way): you have ran catkin_make (or catkin build) after you cloned the MoveIt git repository to your source space, correct?

I edit the post to add a bit more infomation. Hope I get some hints. Thanks

I think you only have to add the one line to the catkin workspace:

source ~/catkin_ws/devel/setup.bash

This bashfile will source the installed environment of indigo itself. Good luck

In official tutorial, it says it would be convenient to do this

echo "source /opt/ros/indigo/setup.bash" >> ~/.bashrc
source ~/.bashrc

Reference to 1.6 Environment Setup, Unbuntu Install of ROS indigo

I follow the tutorial in ros-by-example-2, it says there is bug in MoveIt, so it asks me to apt-get install ros-indigo-moveit-full firslty, and then git clone something, and catkin_make. There is something wrong.

I post catkin_make error question in author's google group and he told me the bug has been fixed, and no need to git clone source package. So I remove the source package, apt-get remove ros-indigo-moveit-full-* , and then reinstall again. finally catkin_make no error.

Here is the solution by Patrick Goebel, author of ros-by-example

Since you had a partially built moveit package in your /root/catkin_ws directory earlier, be sure you first clean out the old stuff before re-running catkin_make:

$ cd ~/catkin_ws
$ \rm -rf devel build
$ catkin_make
$ source ~/.bashrc
$ rospack profile
