US Patent 8453987 Pan and tilt systems

Pan and tilt systems are provided. Pan and tilt systems illustratively include a pan hobby servo motor having a splined output shaft. The splined output shaft rotates about an axis of rotation. In an embodiment, an angular position of the splined output shaft is controlled based at least in part on a coded input signal and an external potentiometer. A pan auxiliary gear is illustratively rotatably coupled to the hobby servo motor splined output shaft. The pan auxiliary gear has an axis of rotation that is approximately parallel to the splined output shaft axis of rotation. In an embodiment, a tilt system is functionally engaged to the pan auxiliary gear such that rotation of the pan auxiliary gear is translated to the tilt system.
