Abstract
A sensor that detects the boundary between a first, relatively higher surface, such as the un-mowed vegetation and a second, a relatively lower surface, such as the mowed vegetation, and a controller for steering the semi-autonomous or autonomous vehicle along detected boundary. The boundary between the two surfaces is detected using a plurality of non-contact distance measuring sensors aligned in same direction, and processes these distance measuring sensors for determining the distance sensors that measure said first relatively higher surface and the distance sensors that measure the second relatively lower surface.
