Title (EN) IMPROVED REDUCTION OF WHEEL TRACKS FOR ROBOTIC LAWNMOWER
(FR) RÉDUCTION AMÉLIORÉE D'EMPATTEMENT D'UNE TONDEUSE À GAZON ROBOTISÉE
Abstract:
(EN) A robotic lawnmower system comprising a robotic lawnmower (100) and a signal generator (240) to which a cable (250, 260) is to be connected, the signal generator (240) being configured to transmit a signal (245) through the cable (250, 260). The robotic lawnmower (100) comprises: a sensor (170) configured to pick up magnetic fields generated by the signal (245) in the cable (250, 260) thereby receiving the signal (245) being transmitted and a controller (110). The controller (110) is configured to follow the cable (250, 260) at a distance by determining a received signal quality level and adapting the distance at which the robotic lawnmower (100) is following the cable at according to the determined signal quality level.
(FR) L'invention concerne un système de tondeuse à gazon robotisée comprenant une tondeuse à gazon robotisée (100) et un générateur de signal (240) auquel un câble (250, 260) doit être connecté, le générateur de signal (240) étant conçu pour émettre un signal (245) par l'intermédiaire du câble (250, 260). La tondeuse à gazon robotisée (100) comprend : un capteur (170) conçu pour capter des champs magnétiques générés par le signal (245) dans le câble (250, 260), ce qui permet de recevoir le signal (245) qui est émis, et un dispositif de commande (110). Le dispositif de commande (110) est conçu pour suivre le câble (250, 260) à une certaine distance en déterminant un niveau de qualité de signal reçu et en adaptant la distance à laquelle la tondeuse à gazon robotisée (100) suit le câble selon le niveau de qualité de signal déterminé.
