Abstract: A docking station for use with an autonomous tool comprising a docking module for detachably receiving the autonomous tool and a guiding module arranged to guide the movement of the autonomous tool towards the docking module, wherein the autonomous tool, upon termination of the movement, is received by the docking module at a predetermined position and orientation. The present invention also discloses an autonomous lawn mower having a docking module and a guiding module and a method of guiding an autonomous tool towards a docking station.
A docking station for use with an autonomous tool (100) comprises a docking module (200) for detachably receiving the autonomous tool (100) and a guiding module (210) arranged to guide the movement of the autonomous tool (100) towards the docking module (200), wherein the autonomous tool (100), upon termination of the movement, is received by the docking module (200) at a predetermined position and orientation (400). An autonomous lawn mower has a docking module (200) and a guiding module (210). A method is applied to guide an autonomous tool (100) towards a docking station.-

Abstract: A navigation system for use in an autonomous tool, comprising a plurality of anchors disposed separately on a terrain each arranged to emit an electromagnetic signal; a signaling module including a signal receiver arranged to receive the electromagnetic signal, wherein the signaling module is connected to the autonomous tool arranged to move on the terrain; and a processor arranged to process the electromagnetic signal received by the signal receiver so as to determine a physical distance between the signaling module and each of the plurality of anchors. The processor is further arranged to determine a current position of the signaling module with respect to a reference position on the terrain based on the determined physical distances and map data of the terrain associated with a position of each of the plurality of anchors. The present invention also discloses a method for controlling an autonomous tool.
