Abstract
The present invention relates to navigation of an autonomous vehicle capable of autonomously tracking a route toward a destination. The present invention provides a system comprising the steps of forming a route for an autonomous vehicle with a plurality of information storing elements placed at specific locations in line along a passageway, each beacon storing its own location information on the route, mounting an information retrieving section on the autonomous vehicle so that as the vehicle travels, the information retrieving section comes in sufficient proximity to the information storing elements in sequence, transmitting radio waves between the information retrieving section and information storing element, supplying, through the transmission of the radio wave, electricity from the vehicle to the information storing element to activate it, retrieving, by the information retrieving section, location information from the information storing element that indicates the vehicle's present position, and controlling a moving direction of the vehicle based on this vehicle's position information.
