ABSTRACT:
A robot wrist is built up of three rotatable tubular wrist parts arranged one after the other, the axes of rotation of the first and the second part intersecting each other and the axis of rotation of the third part intersecting the longitudinal axis of the third part. Three mirrors are arranged inside the wrist, so that a light beam arriving along the axis of rotation of the first part passes unrefracted through the wrist irrespective of the rotary positions of the three wrist parts. The wrist enables processing by laser of workpieces with no restriction of the orientation capacity of the wrist.
