Abstract
An automatic guided vehicle travels for a predetermined distance by detecting the distance covered, and thereafter stops when the mark located at the desired stopping point is detected by at least one sensor. Obstacles on the route, and cumulative error therefore have very little influence on the vehicle's travel, so that accurate travel control is obtained.
