The application of ultrasound in the guidance system (of an AGV)

The use of ultrasound instead of radio waves for the guidance system for an automated guided vehicle (AGV) is proposed because it takes a very long antenna to discriminate between the detected radio waves. An onboard microprocessor-based controller has been implemented. The system function, software, and hardware organization of the AGV are described, and experimental data and error analysis are presented. The proposed concept was tested or a small electrical car. A primitive mathematical model is also proposed.<
