  • Operation of a robotic work tool by adapting the operation to weather conditions
    Patent number: 10842074
    Abstract: A robotic work tool system (200) comprising further comprising a charging station (210) and a robotic work tool (100), the robotic work tool system (200) being configured to determine a change in weather and to take preservation action. The robotic work tool may detect the change in weather by detecting an electrical charge buildup in the boundary wire. The robotic work tool may take the preservative action by the robotic work tool (100) distancing itself from the charging station (210).
    Type: Grant

  • Method and system for guiding a robotic garden tool to a predetermined position
    Patent number: 8942862
    Abstract: The present invention relates to a method (400) and a system (100) for guiding a robotic garden tool to a predetermined position. The robotic garden tool includes a control unit (104) and a sensor unit (102) to detect guiding signals. The sensor unit (102) detects a first guiding signal (110) from a first signal source (106) and the robotic garden tool follows the first guiding signal (110) at a variable distance from the first signal source (106) towards the predetermined position. While within a predetermined distance (D) from the predetermined position, the sensor unit (102) detects a second guiding signal (112) from a second signal source (108). Within the predetermined distance (D), the robotic garden tool follows one of the first and the second guiding signals (110 or 112) towards the predetermined position at a pre-configured distance from the corresponding signal source.
