Hello,
I try to tune PID parameters for a hand model. When I used the gazebo plugin [1] SetPositionPID and SetPositionTarget, I cannot control the some of the joints which are jittering(vibrating).
However, If I use ros_control package [2] with same PID parameters, there is no jittering on the model. More specifically, I am using position_controllers/JointPositionController with ros_control package.
Why there is differences between Gazebo Plugin and Ros control package ? How can I adapt the behavior of ros_control package into the gazebo plugin?
Thank you
