The underlying concept is based on an independent joint control strategy. The joint angles of each actuator are controlled by a cascaded position controller with an inner velocity and a motor-current loop. Strain measurements on each link are fed back to the input of the velocity control loop at the preceding joint. Additionally a zero-vibration input shaper filters the command signal.
