ROBOTIC WORK TOOL SYSTEM AND METHOD FOR DEFINING A STAY-OUT AREA WITHIN A WORK AREA

A robotic work tool system (200) for defining a stay-out area (120) within a work area (150). The stay-out area (120) is an area which is to be excluded from the work area (150) in which a robotic work tool (100) is subsequently intended to operate. The robotic work tool system (200) comprises a boundary definition unit (130) comprising at least one position unit (175) configured to receive position data and at least one controller (110, 210). The controller (110,210) is configured to receive a stay-out area definition trigger signal, which indicates that the boundary definition unit (130) has approached the stay-out area to be defined. The controller (110,210) is further configured to receive, based on the received signal, position data indicating the present position of the boundary definition unit (130) from the position unit (175). The controller (110,210) is further configured to define the stay-out area (120) as an area centered at an offset from the received position data.
