Abstract: In accordance with the present invention, there is provided an automatic guided vehicle (AGV) with a movable chassis and information processor mounted on the chassis for controlling AGV operation. A data storage mechanism in the form of a replaceable PROM is connected to the information processor for storing data representative of AGV operating instructions, such as safety procedure instructions, a facilities map, traffic control instructions, load handling instructions, diagnostic procedure instructions, speed control instructions and the like.

Abstract: A system for allowing an automatic guided vehicle (AGV) to move from a first guided area to a second guided area across an unguided span that separates them. A first guidance structure such as a buried cable is displaced from a second guidance structure. A communications and traffic controller is connected to each of the first and second guidance structures. Also connected to the communications and traffic controller is a transponder for signalling when an AGV is leaving the first guided area.
