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: An AGV and guidance system for transporting material between at least two pickup and delivery stands. The AGV has a chassis for carrying objects. A computer processor is supported by the chassis for controlling and monitoring AGV operation. An interactive display is connected to the computer processor and mounted on the chassis for displaying status, current assignment and diagnostic information relating to AGV operation.

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.
