Torque Reduction Method for Redundant Manipulator

Journal of Robotics and Mechatronics, 1999
Redundant manipulators are used to avoid collisions and conduct motion in which all manipulator links avoid the obstacle in work space. The manipulator changes position by adjusting a redundant degree of freedom, simultaneously, but joint torque saturates and error at the end point increases with the number of components.
