A robotic mower and method for controlling a robotic mower to a predetermined position, by means of a guide wire. The robotic mower includes a control unit and at least one sensor. At least one of the sensors detects a signal from the guide wire and follows the guide wire at a first distance that is randomly determined. The robotic mower follows the guide wire until detecting, by means of the at least one sensor, a signal from a boundary wire and then following the boundary wire at a second distance, which is randomly determined. When detecting that the signal strength from the guide wire falls outside a first predetermined threshold, the robotic mower starts following the guide wire again.
