ABSTRACT:
A multi-directional positioner for moving one element relative to another element wherein a socket in a housing receives a ball with a rotating fit with a portion of the ball projecting outwardly of the socket and being connected to one element and the housing being connected to the other element. An arcuate groove in the socket extends in a plane passing generally through the center of the ball and receives an electrically actuated power unit which is pivotally connected to the side of the ball. An arcuate groove in the outer surface of the ball extends in a plane passing generally through the center of the ball and perpendicular to the groove in the socket and receives an electrically actuated power unit which is pivotally connected to the adjacent portion of the housing. The power units are energized singularly and/or jointly to impart relative movement between the ball and the housing.
