Revision history [back]

This is a shortcoming in the robot model loader code as well as a design flaw in the IK plugins API that we recently addressed.

(1) The RML reads joint limits from ~/robot_description_planning/joint_limits (note the private namespace!) and does not fallback to move_group/robot_description_planning/joint_limits.

(2) ttbomk all IK plugins except for the KDL plugin currently parse the URDF themselves and do not implement the new API yet. In this case the IK plugins would have to lookup and apply the limits on their own model and I don't think anyone does that.

A tested patch for (1) is very welcome in the MoveIt repository.

I believe most plugin maintainers would be happy to get contributed patches for (2) too.
