PURPOSE:To prevent a malfunction due to the soil of a sensor and to improve the reliability for control method of an unmanned truck, by providing a sensor at a place near a rail track and at the same time detecting the distance traveled for the unmanned truck to make the truck perform a prescribed operation. CONSTITUTION:An unmanned truck 2 is driven with control along a rail track 1 in accordance with a predetermined program. The sensors 6 are set at a place near the track 1 and detected by a step detector 5 provided to the truck 2, and said program is actuated to drive with control the motors of the front wheel 3 and rear wheel 4 of the truck 2. In addition, the truck 2 contains a traveled distance detector 7 to store the distance between sensor 6. Thus the detector 7 detects the distance traveled even if the detection is impossible with the sensor 6. In such a way, the above-mentioned program is accurately actuated. |
