PURPOSE:To stop an unmanned traveling car at a fixed position high accurately by forming loop-like detecting points on the prescribed position of a guide wire for guiding the traveling by deforming a part of the wire. CONSTITUTION:The guide wire 2 for guiding the traveling of the unmanned traveling car 1 is laid on the traveling course like a closed circuit and a high frequency power supply 3 is connected to the guide wire 2. Each of plural detecting point loops 4 for detecting ground positions is formed on a prescribed position of the guide wire 2 like the same loop by deforming a part of the guide wire 2. The unmanned traveling car 1 is provided with a steering device 5 on its front body, a driven wheel 6 steered by the device 5, a driving device 7 on its rear body, and a driving wheel 8 driven by the device 7, and always detects the guide wire 2 by a pair of steering coils 9 arranged on the center part to execute automatic traveling. In addition, a pair of position detecting coils 10 for detecting said detecting point loops 4 are arranged on the left side of the body. Consequently, voltages are induced in respective coils 10 in accordance with the distance between two sides 4a of the loop 4 and the traveling car is stopped on the fixed position through a control device. |
