Abstract
A robot includes a yielding element for mechanically coupling first and second arm segments of a robot arm. A motor moves the second arm segment relative to the first arm segment. A sensor determines a relative position of the first arm segment in relation to the second arm segment and outputs a position sensor signal representing the relative position. A control unit controls the motor in accordance with the position sensor signal such that the first arm segment is moved into a desired relative position in relation to the second arm segment, when no external force is applied to the robot arm, and when an external force is applied to the robot arm, the motor generates a counterforce which depends on the deviation between the actual and desired positions. The control unit has a predetermined time constant so that changes in the external force are substantially absorbed by damping elements.
