CONTROL METHOD OF ROBOT APPARATUS AND ROBOT APPARATUS

A control method of a robot apparatus, the robot apparatus including a link and a pair of actuators, obtaining each driving force command value of each of the actuators, and controlling each of the actuators, the control method including: a torque command value computation step; a change computation step of computing a difference between the joint stiffness command value and a value and performing a computation of subtracting a value from the joint stiffness command value; an iterative step of iterating the computations of the torque command value computation step and the change computation step until the difference converges to a value equal to or smaller than a predetermined value; and a driving force command value computation step to compute each of the driving force command values when the difference is converged to a value equal to or smaller than the predetermined value.
