Summary: This study proposes a new method to solve the kinematic hyper redundancy problem in posture control of a robotic arm with redundant degrees of freedom. By controlling strategic points along the arm, the method guides the overall motion of the arm towards the target posture. The method is capable of safely and accurately tracking target postures that are significantly different from the initial posture.
