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 method for use in a robotic work tool system () comprising a server () and a robotic work tool () arranged to operate in an operational area () based on a satellite navigation sensor (), wherein the method comprises: receiving () one or more safety boundaries (--) and storing these in a safety map (A-) of the operational area (), receiving () one or more zone boundaries (----) and storing these in a zone map (A-) of the operational area (), and operating () according to the one or more zone boundaries (----) and the one or more safety boundaries (--), wherein the one or more zone boundaries (----) are related to an operating schedule and the one or more safety boundaries (--) are related to safety concerns for the robotic work tool () and wherein the method is characterized in that the one or more zone boundaries (----) are received by the server () and in that the method further comprises confirming () the one or more safety boundaries (--) on location in the operational area () prior to operating () according to the one or more safety boundaries (--).
