The self-propelling lawnmower moves across an area surrounded by the boundary wire. By encoding a data frame with a recognition code in an alternating current that is Direct Current, DC-balanced and that is randomly transmitted within a predetermined period of time, by means of the signal generator, to the boundary wire a system robust against interference is accomplished. The data frame burst is received by a sensor and decoded by a control unit in the lawnmower. By comparing the received recognition code with a stored recognition code, the control unit determines that the lawnmower is on the inside of the boundary wire if the received recognition code matches the stored recognition code, and on the outside if the received recognition code matches the inverse of the stored recognition code."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for controlling a self-propelling lawnmower","description":"A method and a system for controlling a self-propelling lawnmower including the self-propelling lawnmower having a control unit and at least one sensor, a boundary wire and a signal generator.
