The subject innovation is a mini robot, in order to detect the movement of the possible application objects in various fields such as electronic toys, paste a metal sheet piece on the inner wall of the barrel shape of the device provides power (Vcc), and voltage to the iron balls output (Vout ) couple put in the device, the tubular connecting the wires, the device is moving iron balls are rolling while a configuration that generates the electrical signals while in contact with the metal plate, iron balls have been rolling he dropped a caught and plate in the device while the output voltage (Vout) related to the motion detection unit to detect the movement of the object detected by the signal changes.
The motion detection apparatus according to the present invention, this metal plate is provided on the inner wall of the tubular device which is power (Vcc) is applied to the metal plate; Located inside the barrel of the device output voltage (Vout) of iron bead wire is connected; And wherein the device moves the iron balls the said metal plate and in contact with the metal plate of the power supply (Vcc) is the iron balls through the voltage output (Vout) wires with flows the electric signal is balsaengdoem in accordance with the output voltage (Vout) signal is changed a voltage detection unit for detecting that.
According to the present invention, it is possible to provide a sensor module that can recognize the movement of the object with no time delay. In addition, it is possible to provide a toy, and a game machine capable of providing a wide variety of specific voice (sound) or light relative to the motion of the detected object by using such a sensor module. And, it is possible to provide a device or system that is capable of displaying a specific scene as the detected movement of the object.
