MOBILE VEHICLE CONTROLLER UTILIZATION OF DELAYED ABSOLUTE POSITION DATA FOR GUIDANCE AND NAVIGATION

A mobile vehicle controller for controlling a mobile apparatus that travels along a commanded path. The mobile vehicle controller has a dead reckoning navigation procedure for navigating the controllable mobile apparatus along the commanded path in response to positions data. The mobile apparatus determines its position and provides the position data. A vision system provides the absolute position to the mobile apparatus. The dead reckoning position data is periodically modifying with the absolute position. The dead reckoning procedure is synchronized with the vision system.
