Other comments

Seems like a simple fix, the previous version didn't really make sense? To be fair I'm not quite sure what this file is for, I'm just using it to publish joint data back to ROS in my own script (I needed the joint name, which was stored on each Articulation Body in this component).

This pull request is not needed because we plan to remove the rigid body support in URDF importer.
