摘要： 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).
