This article describes a routing and tracking of an automatically guided vehicle (AGV) in which the guide path used by the vehicle will be put down in phases. The host processor software design allows for update of the guide path definition through a utility interface without basic software modification. Vehicle control includes contention solution, status tracking and dead reckoning maneuvers. The AGV is used to move the product from one manufacturing operation to the next. It uses a reflective chemical guide path in conjunction with an optical sensor on the AGV. At key points along the guide path are four-inch spurs that are placed at a right angle to the track. These spurs are placed in groups to form unique binary number location codes (L-code) that are read by the optical sensor.
