  • Publication number: 20240199080
    Abstract: A robotic work tool system comprising a robotic work tool (100) arranged to operate in an operational area (205), the robotic work tool system comprising controller (110, 240A) being configured to receive (410) a map of the operational area, receive (420) a first temporary boundary (220-1-4), receive (430) a second temporary boundary (220-1-4), and generate (440) a composite boundary (220C) encompassing the first and the second temporary boundaries (220-1-4), wherein the composite boundary (220C) is the boundary (220) for the robotic work tool (100) when operating in the operational area (205).

  • Publication number: 20230195125
    Abstract: The present disclosure relates to a method for controlling an autonomous robotic tool using a modular autonomy control unit. The control unit includes an interface with the autonomous robotic tool and comprises a processor, configured to control the autonomous robotic tool during operation. The modular autonomy control unit transfers a set of test instructions to the autonomous robotic tool, triggering the latter to carry out a set of test actions in response to the test instructions—The modular autonomy control unit detects sensor input in response to the test actions, and computes a corresponding error vector, based on which calibration data is updated. Then, the modular autonomy control unit controls the robotic tool based on the calibration data. This allows a general control unit to be used in connections with several types of robotic work tools.
