  • Navigating a robotic mower with dead reckoning
    Patent number: 12535820
    Abstract: A method navigates a robotic mower (2) comprising at least one sensor (12; 14). The method comprises detecting (S101), by means of the at least one sensor (12, 14), at least one signal from a wire (8) as a first signal source; controlling (S106) the robotic mower (2) to follow the wire (8) at a first distance (D1) to the wire (8); detecting (S108), by means of the at least one sensor (12, 14), at least one signal from a second signal source; detecting (S109) a second distance (D2) based on the at least one signal from the second signal source; and navigating (S110) the robotic mower (2) along a path determined based on the first distance (D1) and the second distance (D2).
