ABSTRACT:
A vehicle is guided along a hall by obtaining distances between it and the nearest objects along a plurality of directions, fitting straight lines through the distances to define the walls of the hall, determining its distance from the center of the hall and its angular orientation with respect thereto and directing it to a given point on the center or other line with an angular rotation so that it faces along the center line.
