    Abstract: A pan and tilt drive system for an electrically powered device includes a housing in which an elongated shaft is rotatably supported, which shaft is rotatably driven about a shaft axis by a pan motor. A receptacle is coupled to the shaft and disposed to pivot about a tilt axis which tilt axis is perpendicular to the shaft axis. A tilt subsystem is provided to facilitate tilt motion of the receptacle about the tilt axis. The tilt subsystem includes a tilt motor, a tilt coupling and a tilt rod. The tilt coupling is coupled between the tilt motor and the tilt rod, while the tilt rod is coupled between the tilt coupling and the receptacle. Actuation of the tilt motor effects linear translation of the tilt coupling in a direction parallel to the shaft axis, thereby causing the tilt rod to tilt the receptacle about the tilt axis.
