ABSTRACT:
An extensible articulated manipulator arm is described in which the distal end is movable in a straight line relative to the proximal end thereof. The articulated arm includes a first arm which incorporates a first parallelogram linkage and a second arm which includes a second parallelogram linkage, the adjacent ends of the parallelogram linkages are drivingly connected to one another whereby rotation of the first arm about the first end support alters the geometry of the first parallelogram linkage which in turn effects a corresponding alteration in the geometry of the second parallelogram linkage, thereby to cause movement of the distal end of the second arm in a straight line relative to the proximal end of the first arm.
