Abstract

The invention relates to a robot arm with a work arm connected to it, a connector moved by motors for tools, workpieces, workpiece grippers or gripper change systems, whereby the motors are located at the end of the work arm opposite the connector, and are connected by output connections with gear wheels mounted in a swiveling axis of a swiveling head of the connector. To make such a robot arm flexible, and moreover to guarantee that the work arm is rigid, it is proposed that the axes (D,E,P) of rotation of the elements (work arm 2, swiveling head 23, connector 3) intersect at a common intersection point (A).
