  • Anthropomorphic medical robot arm with movement restrictions
    Patent number: 8160743
    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.

  • Method for controlling a robot arm, and robot for implementing the method
    Patent number: 7646161
    Abstract: In a method for controlling a robot arm, which is particularly suitable for use in medical applications, a robot arm (10) with a redundant number of joints is used. A torque acting in at least one joint (12a, 12b) is sensed. By means of a control device, the torque acting in this joint (12a, 12b) is controlled to become substantially 0.
