The present disclosure is related to a method for docking an autonomous mobile robot. A first effective area is determined A first effective boundary is determined from the one or more first boundaries of the first effective area. An optimal point on the first effective boundary is determined. The autonomous mobile robot is controlled to move to the optimal point. The steps are repeated to make the autonomous mobile robot reach the vicinity of the charging station. The optimal point may be determined from one or more candidate optimal points. Each candidate optimal point defines a respective second effective area centering on the candidate optimal point and overlapping with the first effective area to form a respective overlapping area. The respective overlapping area associated with the optimal point is smallest among the respective overlapping areas associated with the one or more candidate optimal points.
