ABSTRACT:
A system for controlling x, y and z directional movement of a point adjacent to the free end of an arm composed of a plurality of interconnected articulated arm segments mounted for movement relative to at least three axes and providing for individual, independent control of movement of the point in any selected one of the x, y or z directions by controllably relatively adjusting the relationships between the segments. The system is particularly suitable for use in equipment when the arm incorporates a boom and stick such as backhoes or the like.
