CONTROL DEVICE FOR ROBOT, CONTROL METHOD AND COMPUTER PROGRAM

A control device for a robot including: a hybrid dynamics calculator calculating joint forces that act on immovable joints and the joint accelerations that are generated at movable joints by performing a hybrid dynamics calculation that includes inverse dynamics and forward dynamics using an auxiliary model in which the actuated joints of the robot having the actuated joints and the unactuated joints are immovable; a forward dynamics calculator calculating the acceleration that is generated by known force that acts on the robot using a main model; a joint force determination unit determining the joint force; and a joint force controller controlling the joint force of each joint of the robot.
