Method and system for describing, generating and checking non-wire guidepaths for automatic guided vehicles

Abstract From the Canadian patent

A method and system for controlling the movement of one or more automatic guided vehicles includes a system controller a number of non-wire, automatic guided vehicles (AGV's) and location markers positioned on a floor. The system controller serves as a dispatcher and traffic controller for the system providing, in one embodiment, two way wireless communication to each AGV in the system. Each AVG is equipped with a navigation and guidance system for controlling the AGV's movement along a predefined guidepath. Differential X Y-coordinales from a path point database stored in the system controller are communicated to a given AGV which can then follows the predefined guidepath. communicating …
