Abstract
A system including a boundary wire and a charging station loop. The boundary wire makes a loop in the charging station that is narrower than and crosses the charging station loop. A return signal is received from a control unit commanding a robotic mower to return to the charging station. The robotic mower is controlled to follow the boundary wire until the charging station loop is detected. The robotic mower then follows the charging station loop until detection of a crossing between the charging station loop and the boundary wire loop. The robotic mower follows the charging station loop a first distance, and then moves in a direction straight forward for a second distance. When the robotic mower has moved the second distance it is turned a predefined angle towards the charging station and follows the boundary wire loop until reaching a charging position.
