ABSTRACT:
Apparatus for controlling the spatial orientation of an angularly displacable working head supported by a base and relative to a given frame of reference. The apparatus comprises a linkage having terminal first and second articulate couplers coupling the working head to the base across the longitudinal axis of the linkage, wherein the first and second articulate couplers are located relative to each other to effectively isolate the working head freely of components of acceleration of the base perpendicular to the linkage longitudinal axis, means for sensing the providing control signals derived from said sensing, the relative angular positions and relative angular velocities between the working head and the linkage, and the existing spatial orientation of the working head relative to the given frame of reference, means for applying torque between the working head and the linkage and between the linkage and the base responsive to the derived control signals to control the spatial orientation of the working head relative to the given frame of reference.
