ABSTRACT:
There is described a wrist for an industrial robot, comprising three wrist elements rotatably supported relative to each other around respective rotation axes which are coplanar and mutually inclined, which leave a space inside thereof free for passage of supply cables which are to be connected to the tool secured to the robot wrist. The latter has a front flange for coupling the tool and a plurality of radial outlets for the above mentioned supply cables, so as to allow for the use of a tool coupling flange having a simplified structure.
