Abstract: The present disclosure relates to an implement carrier 1 comprising an implement carrier body 3 driven by a driving arrangement 5 and configured for connecting alternatingly with at least a first 7 and a second 9 implement. The implement carrier further comprises at least one sensor module 11 adapted for scanning at least a portion of the area surrounding the implement carrier 1 and a connected implement 7, 9, such as containing ultrasound sensors and the like. A moveable sensor module arm 13 is provided, having a proximal end 15 connected to the implement carrier body 3, wherein the sensor module 11 is arranged on the sensor module arm at a distance from the proximal end 15. This allows for a flexible placing of the sensor module11 with regard to the implement carrier 1.

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.
