Bio-mimetic control for whole arm cooperative manipulation

This paper studies modeling and bio-mimetic control of a 3D 8-dof whole arm cooperative manipulation system using sensitive skin. The control law is designed based on integration of voluntary movement and reflex considering the system's redundancy. The voluntary task for holding the object is realized by impedance control at four contact points with the object using the contact force information from the sensitive skin. The reflection on the other hand is introduced as a regulation problem of the direction between the points of end-effectors and elbows. We then investigate the exact solutions for the combined motion and their solvable conditions. The validity of the proposed method is investigated by numerical simulations
