Abstract

A manipulator for remote handling in a hostile environment 14, has a slave arm 10 comprising an upper arm 30, a forearm 52 and a jaw mechanism 60. The upper arm 30 is pivotally suspended from a shoulder support 20 and is telescopically extendible such that straight line motion of the forearm 52 is readily obtained. In addition the forearm 52 is arranged to pivot relative to the upper arm 30 through the same angle as the upper arm 30 but in the opposite sense such that the forearm 52 maintains a constant orientation when the upper arm 30 pivots. All the motions of the slave arm 10 may be controlled through mechanical linkages from a drive unit 18 situated outside the hostile environment 14, and extending through shielding 13 into the environment 14.
