Abstract

A motion sensing remote control device including a motion sensing module, a calculation unit, a motion setting unit, a transmit unit and a receiving unit is disclosed. The present invention controls a remote control car to perform various motions by sensing the user'"'"'s gestures. The motion sensing module senses and converts the gestures into a voltage signal for the calculation unit to perform calculation. The motion setting unit generates a corresponding command based on the calculation result of the calculation unit, and transmits the command to the remote control car through the transmit unit and the receiving unit such that the remote control car executes the received command to perform the corresponding motion specified by the user.
