A motion compensated apparatus that can be used as a sleeping platform, stabilizer. The discomfort and danger of a moving surface associated with a ship at sea is well known. The motion of such a surface causes considerable distress in humans and animals. Servos can expand and contract to position the upper portion of the assembly at various angles with respect to the lower portion and to cancel accelerations caused by pitching and rolling. The servos can be controlled by a control system that is driven by a set of motion sensors or a gyro. The sensors or gyro sense the instantaneous position of the deck with respect to an absolute level virtual reference plane. The control system continuously adjusts the apparatus to remain parallel to the absolute level plane. The system contains a quick enough response to track the fast motion encountered on a ship to yield a smooth and comfortable ride according to control system principles. The sensors may comprise accelerometers, gyros, ring gyros, or other methods of sensing the deviation of the deck or platform from a reference level plane.
