A Repeatable Motion Scheme for Kinematic Control of Redundant Manipulators.

Computational intelligence and neuroscience Sep 18, 2019
To achieve closed trajectory motion planning of redundant manipulators, each joint angle has to be returned to its initial position. Most of the repeatable motion schemes have been proposed to solve kinematic problems considering only the initial des...
