Abstract

An anthropomorphic medical robot arm includes a base end, a first arm element, a base joint coupling the base end to the first arm element, a second arm element, a middle joint coupling the second arm element to the first arm element, a distal functional end, a distal joint coupling the distal functional end to the second arm element, and at least one selectively operable movement inhibitor operable on the base joint, middle joint and/or distal joint so as to restrict the functionally possible range of movement of the robot arm to the range of movement of a human arm.
