A robotic work tool system () for defining a working area perimeter () surrounding a working area () in which a robotic work tool () is intended to operate. The robotic work tool system () comprises a boundary definition unit () comprising at least one position unit () for receiving position data; and at least one controller () for controlling operation of the boundary definition unit (). The controller () being configured to receive, from the position unit (), position data while the boundary definition unit () is moved around the working area () to define a preliminary working area perimeter (). The controller () is further configured to identify, based on the received position data, a geometry of the preliminary working area perimeter () approximately corresponding to a predefined geometry; and to adjust the identified geometry to define an adjusted working area perimeter (), wherein the identified geometry is adjusted to correspond to the predefined geometry.

Robotic work tool system, and method for defining a working area perimeter

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