(PF1)Motion Control of Overactuator Mechanisms with Elastic Elements

In oder to avoid the interference between actuators in overactuator mechanism, we have proposed to add elastic elements in the mechanisms to relax the interference. A new direct kinematics taking account of both of kinematic relation and force balance was established. An optimum control scheme to utilize redundant DOF was also proposed and CP-control while keeping high stiffness of the output link could be achieved.
