Abstract
A robotic work tool () comprising a controller () and at least one magnetic sensor () arranged to sense a magnetic boundary signal emitted by a boundary wire, and a first magnetic guide signal emitted by a first guide wire (), wherein the controller () is configured to: detect an at least partial crossing of the first guide wire () from a first work zone to a second work zone, determine an operating status and if the operating status indicates that a crossing is allowed, allow the robotic work tool to cross the first guide wire () to the second work zone, and if not, control the operation of the robotic work tool so that the first guide wire () is not crossed.
