Abstract
A method for using an obstruction detection device, residing on an automated conveyance vehicle, as an input device for supplying a plurality of predetermined control codes to a controller for the vehicle. Each code is related to predetermined vehicle behavior regulated by the controller. Such codes are used for commencing forward movement, commencing backward movement and stopping the vehicle. Furthermore, included within the collection is a subset of codes to be input exclusively by maintenance personnel. That is, the codes within the subset are highly unlikely to occur in the normal course of vehicle operation.
