Abstract

See full text

A robotic mower navigation system has a plurality of landmark tags sequentially spaced along or inside a boundary wire. Each landmark tag has a unique identifier. The robotic mower has a detector for detecting the landmark tags, and a vehicle control unit having memory storing data for each of the landmark tags including the unique identifiers, a departure angle and a distance from the landmark tag to another non-sequential landmark tag. The vehicle control unit determines the shortest route to a specified destination based on the stored landmark tag data.
