Title:

SYSTEM AND METHOD DOCKETING A ROBOTIC MOWER

Document Type and Number:

WIPO Patent Application WO/2019/153133

Kind Code:

A1

Abstract:

The present invention relates to a method and a system for docketing a robotic mower (2) with a charging station (11), the system comprises, a boundary wire (4) and a charging station loop (10) wherein the boundary wire makes a loop (4a) in the charging station (11) that is narrower than and crosses the charging station loop (10). A return signal is received from a control unit (22) commanding the robotic mower (2) to return to the charging station (11). In response thereto, the robotic mower (2) is controlled to follow the boundary wire (4) until the charging station loop (10) is detected. The robotic mower (2) then follows the charging station loop (2) until a crossing between the charging station loop (10) and the boundary wire loop (4a) is detected. Thereafter, the robotic mower (2) is controlled to follow the charging station loop (10) a first distance, and then continuing to drive the robotic mower (2) in a direction straight forward for a second distance. When the robotic mower (2) has moved the second distance it is turned a predefined angle towards the charging station (11) and controlled to follow the boundary wire loop (4a) until a charging position is reached.
