Definitions

  • the present invention may be framed in the garden cleaning field, specifically, in grass maintenance. More particularly, the object of the invention refers to an autonomous robot model of the spider type for cutting the grass and capable of adapting to terrain unevenness,
  • Edwin Beard Budding invented and patented the first lawnmower machine. That mower required a completely manual operation as well as human propulsion that made a blade rotate inside a cylinder for cutting all the grass in its path. As years have gone by, techniques have been improved and new technologies have been created allowing a lower human effort and more efficiency.
  • the present invention provides an autonomous lawnmower robot with a wide range of cleaning coverage and which adapts to the terrain unevenness.
  • a first aspect of the present invention refers to an autonomous robot lawnmower of the spider type comprising: - a central body and
  • robot central body is divided into three sections:
  • - upper section comprising a solar panel and a power plug connected to a battery, and a central processor intended for managing the decision making tasks through an algorithm.
  • Intermediate section comprising an electric motor and a set of sensors configured for collecting information of the surrounding area.
  • a cutting system configured for cutting the grass.
  • the electric motor is configured for moving the legs of the travelling system and the cutting system.
  • the robot comprises four articulated legs attached to the central body.
  • the robot comprises, at the lower section of the central body, a second set of sensors for collecting information of the surrounding area.
  • the cutting system comprises metallic blades or knives. In another preferred embodiment of the invention, the cutting system comprises cutting wires.
  • the cutting system comprises a cutting rotational roller.
  • the robot of the present invention as it has been described has autonomous mobility and allows cutting the grass in uneven surfaced terrains.

Abstract

La présente invention correspond à un robot destiné à tondre le gazon, totalement autonome, se présentant sous la forme de pattes d'araignée, si bien qu'il permet un déplacement sur des surfaces inégales et le réglage du système de coupe en fonction du terrain. Il comprend : une batterie alimentée par un panneau solaire ou de l'électricité, un processeur central destiné à gérer des tâches de prise de décision par l'intermédiaire d'un algorithme, des capteurs latéraux et inférieurs pour collecter des informations, un moteur entraînant les pieds pour le déplacement et le système de coupe.
