  • 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).

  • Patent number: 12464978
    Abstract: A method navigates a robotic mower (2) by means of a wire (4, 8). The robotic mower (2) comprises at least one sensor (12, 14). The method comprises controlling the robotic mower (2) to exit a parking position at a station (11), wherein in the parking position the robotic mower (2) is at least partially arranged at an inside of a loop (10) of the station (11), determining that the robotic mower (2) has moved further outside of the loop (10) by detecting at least one signal of the loop (10) by means of the at least one sensor (12, 14), detecting at least one signal of the wire (4, 8) by means of the at least one sensor (12, 14) and controlling the robotic mower (2) to straddle along the wire (4, 8).

  • Publication number: 20230085538
    Abstract: The disclosure provides a robotic mower and its path planning method, system and device. The method includes controlling the robotic mower to exit the charger station until it is outside the loop of the charger station and continue to move for a random distance; and controlling the robotic mower to search the boundary wire or guide wire, wherein the boundary wire is pre-laid at the edge of the working area of the robotic mower, the guide wire is pre-laid in the working area of the robotic mower; the robotic mower is controlled to move by following the boundary wire or guide wire until a predetermined target distance is traveled. With the disclosure, tracks generated when the robotic mower exit the charger station along a fixed path can be avoided, and the damage to the lawn or vegetation can be reduced.

  • Publication number: 20230071262
    Abstract: A robotic mower and a path planning method, system and device are provided and the method includes controlling the robotic mower to exit a charging station, controlling the robotic mower to find a boundary wire or guide wire, where the boundary wire is pre-laid on the edge of the working area of the robotic mower, and the guidance line is pre-laid in the working area of the robotic mower, controlling the robotic mower to follow the boundary wire or guide wire to move until it reaches the predetermined position. With the disclosure, tracks generated when the robotic mower exit the charging station along a fixed path can be avoided, and the damage to the lawn or vegetation can be reduced.
