Abstract:
This overhead traveling vehicle system comprises: a rail guided cart that moves in a first direction when a traveling unit travels on a pair of first rails, and that moves in a second direction when the traveling unit travels on a pair of second rails; and a cart controller that controls the rail guided cart. The pair of first rails and the pair of second rails are provided with position recognition marks. The rail guided cart is disposed to face the position recognition marks, and has four position recognition sensors that are disposed to face the position recognition marks. The cart controller derives, on the basis of position information acquired by the position recognition sensors, a deviation amount between a predetermined position in a cell and a stop position of the rail guided cart.
