ABSTRACT:
A method and an apparatus for producing rapid movement and smooth braking and a precisely defined final position of a movable robot arm. For moving the robot arm from a first operative position to a second operative position the robot arm is first driven by a rapidly rotating motor until it comes close to its second operative position, at which time a slowly rotating motor with an associated coupling takes over the drive and reduces the driving speed of the robot arm progressively. When the robot arm reaches its final position a brake is actuated so as to clamp said robot arm.
