Abstract
An automatic guidance device for a self-powered cargo-moving vehicle is bolted directly over the steering column of the vehicle and is operated by a vehicle-borne sensor which follows a magnetic wire path, the guidance system having an automatic, sensor-directed mode, a manually operated power steering mode, and a manual override mode in which the guidance device is effectively disconnected and steering is undertaken by a direct mechanical linkage with the vehicle steering column.
