A prosthetic or robot part (10), comprising a base (12), a proximal (14) and a distal (16). The proximal (14) is mounted on the base (12) so as to be rotatable thereabout in a given sense. The distal (16) is mounted on the proximal (14) so as to be rotatable thereabout in the same sense to effect a gripping action of the prosthetic or robot part (10). The proximal (14) and the distal (16) are rotatable in the opposite sense to release the grip. One part (34, 36) of a drive (32) of the part (10) is pivoted to the base (12) about a base pivot axis. Another part (38) of the drive (32) is pivoted to the distal (16) about a distal pivot axis. The distal (16) is also pivoted to the proximal (14) about the said distal pivot axis. Thus the proximal (14), the distal (16) and the said another part (38) of the drive (32) are all pivotable relative to one another about the said distal pivot axis. |
