  • Navigation for a robotic lawnmower system
    Patent number: 12648514
    Abstract: A method for use in a robotic lawnmower system comprising a robotic lawnmower arranged to operate in an operational area based on the satellite navigation sensor, determining that the robotic lawnmower is in a satellite shadowed area and in response thereto querying the map application for a reference object, and navigate to the reference object based on the deduced reckoning sensor, determining that the reference object has been reached based on the object sensor and, if so, confirming a new position of the robotic lawnmower, determining that the robotic lawnmower is not in the satellite shadowed area and in response thereto again operate based on the satellite navigation sensor.
