Abstract
An automated guided vehicle (AGV) control system which is compatible with existing guidewire systems providing both guidewire and autonomous navigation and communication between a central controller and each vehicle. Autonomous vehicle navigation includes update markers which may be spaced well apart, such as fifty feet. Inputs from linear travel encoders from the vehicle's drive wheels, position measurements from the update markers, and bearing measurements from a novel angular rate sensing apparatus, in combination with the use of a Kalman filter, allows correction for navigation and guidance errors. The control system comprises high frequency two-way data transmission and reception capability over the guidewires and via wireless communications. Novel navigation algorithms are used to select and calculate a non-linear path to each next vehicle waypoint when the vehicle is operating in the autonomous mode. The non-linear path comprises an initial direction equal to the heading of the vehicle as it enters the path and a waypoint heading defined as part of the message received from a central control system which controls travel of each vehicle in the system.
