摘要

A wrist (16) for an articulated robot has an operative member (45) which is rotatable about three mutually perpendicular axes (17, 18, 19) and three motor units (27, 29, 46) each of which can cause the operative member (45) to rotate about only one of the three axes (17, 18, 19) without causing any rotation about the other axes.
