PURPOSE:To eliminate a malfunction owing to the soil on the reflecting surface compared with a light reflection system by constituting an unmanned guide carrying device with a truck containing a sensor for metallic matters to control the actuation of a steering wheel and a guide path containing a metallic matter laid on its surface. CONSTITUTION:A sensor 4 which detects a metallic matter 3 on the guide path surface 2 is put on a truck 1. The output of the sensor 4 is amplified, and the direction of a steering wheel is controlled by a servo motor. At the same time, a driving wheel is driven by a motor. Thus the self-traveling is possible for the track 1. The sensor 4 is provided with detection coils 6a and 6b, a resistance, a capacitor, impedance elements 7a and 7b of inductances, etc., an oscillator 8 of several kHz, and an output terminal 9. A bridge is formed with the coils 6a and 6b and the elements 7a and 7b. |
