ABSTRACT:
An articulated joint, for example in a robot arm, has a braking device which can brake movement in the joint when desired, so that forces transmitted across the joint are not transmitted through the mechanism which moves the arm. The braking device has an annular expandable, for example tubular, element which is positioned between concentric facing surfaces on either side of the joint, i.e. on the arm and on the part of the robot to which the arm is articulated. Hydraulic pressure can be applied to the expandable element to cause it to expand and lock together the concentric surfaces.
