Abstract: The disclosure provides a robotic mower and a control method, a system and a storage medium thereof. The control method includes: controlling the robotic mower to move to a starting point; selecting a path map from a pre-stored path map set; and controlling the robotic mower to move and work according to the selected path map. The path map set is a path map pre-planned according to different moving angles according to a working area of the robotic mower. With the disclosure, it may ensure that the robotic mower walks along different paths each time it works, thereby avoiding ruts caused by repeated rolling of the working area.

Abstract: A method performed by a robotic garden system for controlling a robotic garden tool (1). The system comprises the robotic garden tool (1), a control unit, and a database. The method comprises the steps of: A. Retrieving a predetermined route (3) for a working area (4). The predetermined route (3) is based on a travel angle (6). The travel angle (6) is an angle extending from a starting point (7). The working area (4) delimits the travel of the robotic garden tool (1). A route data set comprises a plurality of predetermined routes. Each predetermined route has a travel angle substantially being different from all other travel angles of all other predetermined routes. B. Controlling the robotic garden tool (1) to start from the starting point (7) and move along the retrieved predetermined route (3).
