Beschreibung
Zusammenfassung:	A robotic work tool system (200) comprising a charging station (210) and a robotic work tool (100), said robotic work tool (100) comprising a position determining device (190) and a controller (210), wherein said controller (210) is configured to determine a current position for the robotic work tool (100) based on the position determining device (190), determine a first distance from the current position to said charging station (210), cause said robotic work tool (100) to travel a predetermined distance or for a predetermined time, determine a new current position for the robotic work tool (100) based on the position determining device (190), determine a second distance from the new current position to said charging station (210), determine if the second distance is larger than the first distance; and if so, cause the robotic work tool (100) to turn towards the charging station (210).
