Abstract
A freely programmable multi-axis articulated manipulating arm unit having arm elements disposed along different longitudinal axes especially for use as an industrial robot is provided with a drive system and a brake system for each of individual rotational or translational axes; the drive systems belonging to the rotational or translational axes of the manipulating arm unit are each provided with a hydraulically actuated locking brake which functions in a play-free manner, when in the operating braking state. Each of these brakes fixes adjacent arm-elements with respect to each other. Said adjacent arm elements are able to move about the rotational axes relative to each other when the said brakes are not operative. The arm elements are fixed directly in every position, that is, without the use of intermediate elements.
