Abstract

A camera stabilizing support apparatus includes motorized "x-y translation" of one or more components of the camera equipment, such that no mechanical forces are imparted to the overall system which would adversely affect the angular position of the gimbaled mass, synchronous control of the motion of lower masses of the camera stabilizing support apparatus so that both dynamic and static balance is preserved throughout the range of motion, and an adjustable gimbal mechanism which serves to isolate the system'"'"'s equipment support from the support arm extending from the operator'"'"'s body harness which provides both coarse and fine location adjustment, and provides positive self-centering for these gimbal locking elements so that no clamp distortion occurs.
