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.

Abstract: A device for supporting and adjusting a mirror in a laser-robot system including a plurality of mirrors which reflect a laser beam in succession along a predetermined path to a head for emitting the laser beam includes a mirror-holder, a member which supports the mirror-holder for rotation about a center of rotation which lies on the reflecting surface of the mirror, and a mirror adjustment unit with first adjustment means for rotating the mirror holder about a first axis which passes through the center of rotation and second adjustment means for rotating the mirror-holder about a second axis which intersects the first axis perpendicularly at the center of rotation.
