Hi all!

I have installed moveit! and I have now a little experience with the rviz plugin. My aim is to compare some planning algorithms with two or three scenes, using the pr2 robot. I was able to spawn the pr2 following the tutorials and plan some motions, but after having imported a scene from the "Scene Object" pan, by clicking on the "Import from text" button (like in this tutorial http:\\wiki\Environment_Representation\Rviz, "Importing from Text Files" paragraph), I am not able to tell the planning algorithms to take into account of the collisions with the scene. The movements planned are going through the scene objects...

I didn't find anything in the tutorials, but maybe I wasn't looking the right pages.

Any help about making collisions work also with the environment? Self-collision checking works perfectly...

Thanks in advance!

The problem is that the scene you are editing is actually the one in Rviz, not the one for the planning algorithm (which runs in a separate process). You need to publish the scene you changed (imported geometry to) to the move_group node. This can be easily done by clicking the Publish Planning Scene button in the Context tab of the motion planning plugin frame. From that point on, planning algorithms should use the updated geometry.
