  • METHOD IN A SELF-PROPELLED ROBOTIC LAWNMOWER AND A SELF-PROPELLED ROBOTIC LAWNMOWER
    Publication number: 20260093267
    Abstract: A method for operating a self-propelled robotic lawnmower that is configured to operate in a pseudo random pattern in a work area may include driving means, processing means, and a camera. The method includes detecting a rough grass patch condition, defined as an estimated ratio of uncut to cut grass in the work area falling below a threshold. Then, a rough grass patch is identified using the camera, and the lawnmower steers towards and processes the identified rough patch.

  • Robotic tool, and methods of navigating and defining a work area for the same
    Patent number: 12185663
    Abstract: A method of navigating a self-propelled robotic tool (14) within a work area (12) defined by a boundary (13) comprises determining a positioning status comprising a position (P) of the robotic tool (14) within the area; based on the determined position (P) of the robotic tool (14), estimating a boundary distance value indicative of a distance (D1, D2, D3) from the robotic tool (14) to the boundary (13); setting a maximum dead reckoning navigation distance based on the boundary distance value; if a new positioning status cannot be reliably obtained, continuing navigating the robotic tool (14) based on dead reckoning; and if no new positioning status of the robotic tool (14) within the area has been reliably obtained upon reaching the maximum dead reckoning navigation distance, executing a safety operation based on having reached the maximum dead reckoning navigation distance.
