Abstract
The present invention relates to a method (300) and a system (100) for navigating a robotic garden tool (202) based on one or more operating parameters for subareas (210-218) within the working area (204) and a current location of the robotic garden tool (202). The working area (204) is provided with a signal source (104) corresponding to which a sensor unit (106) is provided in the robotic garden tool (202) for detecting the one or more signals (102) from the signal source (104). The robotic garden tool (202) may include a low-accuracy positioning device (110) for providing co-ordinates of various subareas (210-218) and at any given instant, an approximate location of the robotic garden tool (202). The robotic garden tool (202) further includes a processor means (114) for comparing the coordinates of the subareas (210-218) and the approximate position of the robotic garden tool (202) to determine a current location of the robotic garden tool (202) in the working area (204).
