<p>Robot wrist comprising a plurality of mutually rotatable tubular parts arranged in series with each other and a tubular member (2), such as an tool attachment, said member (2) being rotatable mounted to one (1) of said parts and, via a tubular gear, being driven by a separate motor. According to the invention said motor (10,11) has a tubular rotor (11) which, along with said tubular gear (4,5,15,12), is concentrically arranged with said tubular member (2) to form a channel for supply and/or communication means. The robot wrist exhibits a great orientation capacity in space while having at the same time a relatively small diameter, which enables the insertion of the part (1) into confined spaces.</p> |
