Robotic mower and method for controlling a robotic mower

A method for controlling a robotic mower to a predetermined position, by means of a guide wire within an area delimited by a boundary wire, said robotic mower comprising a control unit and at least one sensor, the method comprising:

• detecting, by means of the at least one sensor, a signal from the guide wire,
• following the guide wire at a first distance, wherein the first distance corresponds to a given first signal strength that is sensed by the at least one sensor and wherein the control unit randomly selects the first signal strength each time the guide wire signal is detected,
• detecting by means of the at least one sensor, a signal from the boundary wire,
• following the boundary wire at a second distance, wherein the second distance corresponds to a given second signal strength that is sensed by the at least one sensor and wherein the control unit randomly selects the second signal strength each time the boundary wire signal is detected,
• detecting that the first signal strength from the guide wire falls outside a first predetermined threshold, and
• following the guide wire again.

A robotic mower controllable to a predetermined position, by means of a guide wire within an area delimited by a boundary wire, said robotic mower comprising a control unit and at least one sensor, wherein the control unit comprises a processor and a memory, the memory comprising instructions which when executed by the processor causes the robotic mower to:

• detect, by means of the at least one sensor, a signal from the guide wire,
• follow the guide wire at a first distance, wherein the first distance corresponds to a given first signal strength that is sensed by the at least one sensor and wherein the control unit randomly selects the first signal strength each time the guide wire signal is detected,
• detect, by means of the at least one sensor, a signal from the boundary wire,
• follow the boundary wire at a second distance, wherein the second distance corresponds to a given second signal strength that is sensed by the at least one sensor and wherein the control unit randomly selects the second signal strength each time the boundary wire signal is detected,
• detect that the first signal strength from the guide wire falls outside a first predetermined threshold, and
• follow the guide wire again.
