Abstract
An apparatus for cutting grass comprising: a lawn mower equipped with wheels and one or more blades for cutting grass; a perimeter cable delimiting a cutting area; a management device for generating an electrical signal (ES) in the cable; a recharging base. The lawn mower further comprises a control unit equipped with: sensor to detect the electrical signal (ES); a memory to store a maximum value (Vmax) and a minimum value (Vmin); a calculation module to determine, for intensity of detection, a target value (Tv) that is non-null and comprised between the maximum (Vmax) and minimum value (Vmin), the target value (Tv) being different from a preceding target value; an operative module to command the wheels so as to move the lawn mower in such a manner that the sensor detects the electrical signal (ES) at an intensity equal to the target value (Tv).
