Abstract
An actuator and a robot are capable of properly adjusting the compliance of the motions of links in response to external forces according to an environment or application. The actuator sets a drive command angular velocity on the basis of a desired motor angular velocity, which is the resultant angular velocity of a desired link angular velocity and a desired driven angular velocity. The component of the desired link angular velocity included in a resultant desired velocity imparts stiffness to the motion of a link, while the component of the desired driven angular velocity included in the resultant desired velocity imparts flexibility to the motion of the link. Thus, the balance between the stiffness and the flexibility of the motion of the link is adjusted by adjusting the resultant ratio between the desired link angular velocity and the desired driven angular velocity.
