ABSTRACT:
A system and method for determining the position of an automatically guided vehicle within a workspace is disclosed which operates by detecting sounds generated by beacons placed within the workspace. The time for the beacon sounds to reach the vehicle is measured and a distance to each beacon is determined. From these measured distances and the known positions of the beacons, the vehicle can determine its relative position.
