Zusammenfassung:	A method for charging a self-propelled robotic work tool (1) in a charging station (4), comprises the steps of: the robot (1) navigating towards a charging position in the charging station (4), and sensing an attaining of a predetermined charging position of the robotic work tool (1) in the charging station (4). A charging position sensor (6a) and a sensed feature (6b) are arranged in the self-propelled robotic work tool (1) and the charging station (4). A charging procedure is initiated once said charging position is attained, and the sensor (6a) detects the sensed feature (6b) in a contactless manner.A system includes a charging station (4) and a robotic work tool (1), which each comprises one of a sensor (6a) and a sensed feature (6b), respectively, as well as first and second charging means (5a, 5b). The sensor (6a) and sensed feature (6b) are arranged for contactless detection.A robotic work tool (1) for use in the system comprises a charging position sensor (6a), a chargeable battery, and a charging means (5a).
