ABSTRACT:
The slave arm (15) in a sealed containment (12 or 210) is arranged to be replaceable by forward displacement by a new arm (115 or 215). The new arm is preceded by an intermediate sealing body (101 or 201) sealed on the new arm by a flexible bag (103 or 203) which is removable into the sealed containment once the new arm is located in the sealed containment. Preferably the sealed containment (12) is spaced from a shield wall (10) to provide an interspace (13) accessible to a protected operator and the linking part (16) of the manipulator has a demountable coupling (24) in the interspace so that the new arm can be inserted from the interspace.
