Abstract
A rail-guided vehicle system includes a detectable portion in front of a carrier at a predetermined position in a traveling direction and detectable by an obstacle detector, and a controller to determine a state of the obstacle detector based on a detection result of the detectable portion by the obstacle detector. The detectable portion is movable to advance into a travel space of the carrier at a time of inspection to check operation of the obstacle detector and to retreat from the travel space of the carrier at a time of passage when the carrier passes through an advance position of the detectable portion.
