More Information
Summary:A method for use in a robotic work tool (100) arranged to operate in an operational area, the robotic work tool comprising a memory configured to store a location of at least one object, a distance sensor (195), a navigation sensor (185) being based on signal-reception and a controller, the method comprising:determining a location of the robotic work tool (100) utilizing the navigation sensor (185);determining that a shadowed area is encountered, wherein navigation utilizing the navigation sensor is not reliable; and in response theretonavigating utilizing the distance sensor based on detecting at least one object and a distance to the at least one object utilizing the distance sensor (195), the stored at least one object and the location of the robotic work tool (100).
