Abstract: A method for use in a robotic work tool system (200) comprising a server (240) and a robotic work tool (100) arranged to operate in an operational area (205) based on a satellite navigation sensor (175), wherein the method comprises: receiving (410) one or more safety boundaries (220, 220-1, 220-2) and storing these in a safety map (120A-1) of the operational area (205), receiving (420) one or more zone boundaries (220-3, 220-4, 220-5, 220-6) and storing these in a zone map (120A-2) of the operational area (205), and operating (440) according to the one or more zone boundaries (220-3, 220-4, 220-5, 220-6) and the one or more safety boundaries (220, 220-1, 220-2), wherein the one or more zone boundaries (220-3, 220-4, 220-5, 220-6) are related to an operating schedule and the one or more safety boundaries (220, 220-1, 220-2) are related to safety concerns for the robotic work tool (100) and wherein the method is characterized in that the one or more zone boundaries (220-3, 220-4, 220-5, 220-6) are received by

Abstract: A robotic work tool system (200) comprising a robotic work tool (100) comprising at least one body part (140, 140-1, 140-2, 140-3) and at least one navigation sensor (170, 175) being configured to receive a control signal (225, 235), wherein at least one of the at least one navigation sensor (170, 175) is arranged on the at least one body part (140, 140-1, 140-2, 140-3). The robotic work tool (100) being configured to determine that said control signal (225, 235) is not reliably received and in response thereto rotate at least one of the at least one body part (140, 140-1, 140-2, 140-3) comprising at least one of the at least one navigation sensor (170, 175) in a first direction to attempt to regain reliable reception of the control signal (225, 235).
