Patent attributes
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 calculation step of using the target stiffness, the target trajectory, angular velocity of the target trajectory, and angular acceleration of the target trajectory to calculate a torque command value; a determination step of determining whether each of the driving force command values is a value 0 or greater; a change step of performing at least one of a change of increasing the target stiffness and a change of reducing the angular acceleration; and a driving force command value calculation step of using the target stiffness and the torque command value to calculate each of the driving force command values.
