Abstract: A robotic work tool system (200) for defining a working area (205) in which a robotic work tool (100) is subsequently intended to operate. The robotic work tool system (200) comprises a robotic work tool (100), at least one controller (210) and at least one memory (220). The robotic work tool (100) comprises at least one sensor unit (170) configured to collect sensed input datawhile the robotic work tool (100) is driven around the working area (205) to preliminarily define a perimeter around the working area (205). The at least one controller (210) is configured to establish a preliminary working area perimeter (250). The at least one memory (220) is configured to store a perimeter adjustment function and instructions that cause the at least one controller (210) to adjust the perimeter of the working area (205) by applying the stored perimeter adjustment function to the established preliminary working area perimeter (250)and thereby produce an adjusted working area perimeter (260).The perimeter adjustment function is based on the collected sensed input data corresponding to terrain features.

Abstract: The present disclosure relates to a method for a robotic work tool system (220). The method comprises receiving (S100) a request for assistance from a first outdoor robotic work tool (100a) that at present is not operational and acquiring (S200) position data for the first outdoor robotic work tool (100a). The method further comprises controlling (S300) a second outdoor robotic work tool (100b) to move towards the position of the first outdoor robotic work tool (100a), and controlling (S400) the second outdoor robotic work tool (100b) to acquire camera images of the first outdoor robotic work tool (100a) using a camera device (171).

Abstract: A method (100) of providing a current position estimate of a first robotic tool (r1) of a robotic tool system (1) is disclosed. The robotic tool system (1) comprises the first robotic tool (r1) and one or more second robotic tools (r2, r2', r2''). The method (100) comprises the steps ofoutputting (110) a beacon signal/signals (Bs) from the one or more second robotic tools (r2, r2', r2''), receiving (130) the beacon signal/signals (Bs) at the first robotic tool (r1), andproviding (150) a current position estimate of the first robotic tool (r1) based on the received beacon signal/signals (Bs). The present disclosure further relates to a robotic tool (r1, r2, r2', r2'') and a robotic tool system (1) comprising two or more robotic tools (r1, r2, r2', r2'').

Abstract: A self-propelled robotic lawnmower (1) is disclosed comprising a lawnmower body (3) and a number of lawnmower support members (5, 5', 6) configured to support the lawnmower body (3) by abutting against a ground surface (2) in a first plane (P1) during operation of the robotic lawnmower (1). The robotic lawnmower (1) further comprises a first cutting unit (11), a second cutting unit (12), and a control arrangement (21) configured to control operation of the first and second cutting units (11, 12) based on whether the robotic lawnmower (1) is propelled in a forward moving direction (fd) or in a reverse moving direction (rd) of the robotic lawnmower (1).
