Abstract: The present disclosure relates to a robotic working tool system comprising a robotic working tool (1), and a navigation arrangement enabling the robotic working tool to navigate within a working area (3) defined by a working area boundary (13). A recording unit (62) is used to establish at least first and second sub-areas (21-47), defined by closed perimeters. A mapping unit (60) is used to provide the working area to the robotic working tool (1) as a composite area (49, 51) with a closed perimeter, which is defined by the union of said first and second sub-areas (21-47).

Abstract: A robotic work tool system (200) for defining a working area perimeter (105) surrounding a working area (150) in which a robotic work tool (100) is intended to operate. The robotic work tool system (200) comprises a boundary definition unit (300) comprising at least one position unit (175) for receiving position data; and at least one controller (210) for controlling operation of the boundary definition unit (300). The controller (210) being configured to receive, from the position unit (175), position data while the boundary definition unit (300) is moved around the working area (150) to define a preliminary working area perimeter (110).

Abstract: A robotic work tool (100) comprising a chassis (110) and a body (120). The robotic work tool (100) further comprises at least one input unit (170, 180) for receiving input data relating to an operation of the robotic work tool (100), and at least one collision sensor arrangement (140) for detecting a direction of a movement of the chassis (110) with respect to the body (120). The movement is indicative of a collision. The robotic work tool (100) further comprises at least one controller (130) for controlling operation of the robotic work tool (100). The at least one controller (130) is configured to receive, from the at least one input unit (170, 180), said input data relating to the operation of the robotic work tool (100). The at least one controller (130) is further configured to adapt a collision threshold based on said input data relating to the operation of the robotic work tool (100).

Abstract: A robotic work tool system (200) for redefining a work area perimeter (150) surrounding a work area (105) in which a robotic work tool (100) is subsequently intended to operate. The work area perimeter (150) comprises a plurality of boundary segments (155,160). The robotic work tool system (200) comprises at least one boundary detection unit (170) configured to detect a position of a boundary segment (155,160) of the work area perimeter (150). The robotic work tool system (200) further comprises at least one controller (110,210) configured to determine if a detected position of a boundary segment (155,160) is closer than a threshold distance to a safety perimeter (330). The at least one boundary detection unit (170) is not allowed to cross the safety perimeter (330).
