A remotely operable machine (1) comprises a manipulator arm (17), a machine body (3), and a support (5). The support is disposed between the machine body and the manipulator arm for coupling the arm to the body. The support is movable from one position (D) to another (E) relative to said body so as to provide for variation or extension of the reach of the manipulator arm. The support may be provided by a linkage having an attachment (15) for pivotally supporting the arm, the attachment being pivotally coupled to an extension arm (19) at one end thereof, the extension arm being pivotally coupled to the machine body at its other end. Alternatively, a track assembly for facilitating movement of the support on the machine body may be provided. The track assembly or linkage are configured to allow deployment of the support on the ground adjacent to said body. |
