Abstract
A device is provided for the automated manufacture of screw connections. A jointed arm robot has an output element and an end link. The output element is arranged on the end link so as to be rotatable around an effector axis (wE). A screwdriving tool is rotatable around the effector axis (wE) by the output element. The device features at least one transmission operatively connected to the output element and the screwdriving tool, and transmits a speed between the output element and the screwdriving tool.
