A robotic work tool system () comprising a robotic work tool (), the robotic work tool () being configured to determine () that the robotic work tool () has entered a state of limited movement; determine () an exit path; and exit () the state of limited movement by navigating the exit path.

Exit path determination for a robotic work tool

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.
