Abstract
A method for providing destination and vehicle function information to an AGV comprises the steps of providing one or more stationary dynamically codeable passage transducers (5) at predetermined spaced-apart points along an AGV path (220). The AGV path (220) is provided with a separate guidance wire (W1, W2, W3) or other guidance system. Each of the transducers (5) has a digital readable instruction set representing instructions to the vehicle. A transducer reader is provided on each AGV (200) for reading the instruction set of each transducer (5) as the AGV (200) proceeds along path 220 past the transducer (5) in reading relation. The instructions read are interfaced with the control system of the AGV (200) to provide a predetermined AGV (200) response. Additional steps in the method permit reprogramming of each transducer (5) by a reader/writer (129) on each AGV (200) to provide different instructions to a following AGV (200) and also a way of determining priority of movement between two converging AGVs (200).
