Abstract[English]
The present disclosure relates to a robotic lawn mower (1 ) comprising a body (3), at least two drive wheels (5a, 5b), a drive motor arrangement (7a, 7b) drivably connected to the drive wheels (5a, 5b), and at least one swivelable wheel (6) adapted to swivel around a swivel axis (ax1 ). The robotic lawn mower (1 ) further comprises a control unit (21 ), adapted to control the operation of the robotic lawn mower (1 ), and an offset rotatable grass cutting disc (12) having an offset rotation axis (ax2). The offset rotation axis (ax2) is arranged at a first distance (d1 ) from a longitudinal center plane (LCP) of the robotic lawnmower (1 ). The robotic lawnmower (1 ) comprises a guard (13) covering at least a portion of the offset rotatable grass cutting unit (12), where the guard (13) is attached to a pivot axle (ax3) and arranged to pivot with the pivot axle (ax3) in dependence of a travelling direction (D1, D2, D3) of the robotic lawn mower (1 ).[French]
La présente invention concerne une tondeuse à gazon robotisée (1) comprenant un corps (3), au moins deux roues motrices (5a, 5b), un ensemble moteur d'entraînement (7a, 7b) relié en entraînement aux roues motrices (5a, 5b), et au moins une roue pivotante (6) conçue pour pivoter autour d'un axe de pivotement (ax1). La tondeuse à gazon robotisée (1) comprend en outre une unité de commande (21) conçue pour commander le fonctionnement de la tondeuse à gazon robotisée (1), et un disque de coupe d'herbe rotatif décalé (12) ayant un axe de rotation décalé (ax2). L'axe de rotation décalé (ax2) est disposé à une première distance (d1) d'un plan médian longitudinal (LCP) de la tondeuse à gazon robotisée (1). La tondeuse à gazon robotisée (1) comprend une protection (13) recouvrant au moins une partie de l'unité de coupe d'herbe rotative décalée (12), la protection (13) étant fixée à un axe de pivotement (ax3) et conçue pour pivoter avec l'axe de pivotement (ax3) en fonction d'une direction de déplacement (D1, D2, D3) de la tondeuse robotisée (1).
