[ros-users] trajectory error in simulation / controller parameters

Hello everyone,

I'm a student at University of Stuttgart and work at IPA Fraunhofer with the
We have here some problems with the planned trajectory in simulation. The
actual executed trajectory of the robot arm in rviz differs from the planned
one (display_path (motion_planning_msgs/DisplayTrajectory)). We guess that
it comes from the dynamic model and the chosen controller parameters in the
arm_controller_cob3-1.yaml file
So we're looking for ideas, hints and rules how to choose these parameters
or explanations where the trajectory error could come from.

Thanks in advance for your help!
