1. An automated window mechanism for a window having a sliding panel and a frame, the automated window mechanism comprising:
a motor unit coupled to the window; and
a transmission component between the motor unit and the window and being configured to transmit motion of the motor unit into movement of the sliding panel relative to the frame, wherein the transmission component comprises two or more interconnected pieces with a tolerance therebetween;
wherein the motor unit drives the sliding panel in a first direction in response to an instruction;
wherein upon reaching an endpoint, after driving the sliding panel in the first direction, the motor unit retreats from the endpoint by moving in a second direction opposite to the first direction until energy stored in the transmission component is released and the transmission component rests in a neutral position in which the transmission component does not store energy.
