Abstract: A computer controlled transport system for carrying materials, such as semiconductors, to various work stations at spaced apart locations within a common facility. The system comprises a routing controller, a monorail track extending past the work stations and consisting of a plurality of modular track sections. The track sections are interconnected to one another by at least one routing module, such as a turntable, transfer station, etc., to establish plural paths along the track. Plural cars are provided for supporting the materials and carrying them along the track. The cars are battery powered. The system also includes plural control modules located adjacent the track at spaced locations. Each car is individually identifiable and includes control circuitry and communication circuitry. Each of the control modules also includes control circuitry and communication circuitry. The control modules are connected to the routing controller by a local area network.
