Developments in the measuring of the absolute position of automated guided vehicles

The authors discuss the real-time aspects of the absolute position measurement of an AGV (automated guided vehicle) whose guidepath has been encoded with a pseudorandom binary sequence (PRBS). In particular, the problem of pseudorandom-to-natural-binary code conversion and the resulting improved AGV navigation are discussed. Different approaches to the code conversion process are examined, and a cost analysis of the different approaches is presented.<
