<p>PURPOSE:To provide the unmanned travel system wherein an unmanned travel vehicle can selects an optional route among plural travel routes and travel by itself along the route. CONSTITUTION:In the unmanned travel system wherein the unmanned travel vehicle travels by itself along a guidance line 12 while detecting it, plural loops L1 and L2 are formed of one guidance line 12 and currents are supplied in the same direction to guidance line parts (parts (b) and (f), and parts (d) and (g)) at a branch point A and a confluence point B. Only one guidance line 12 constitute the loops L1 and L2, so the value of a current flowing through the guidance line 12 is constant and the unmanned travel vehicle can travel along the guidance line 12 by securely detecting the guidance line 12 along the route at all times whichever route the unmanned travel vehicle travels along.</p> |
