| description | An autonomous machine comprises driving means for moving the machine along a surface of an area, and a navigation system. The navigation system causes the machine to follow a boundary of the area, storing path information on the path travelled by the machine as the machine follows the boundary and compares when the machine has returned to a previously visited position in the area. The navigation system compares the latest section of the path travelled by the machine with information representing a section of the path previously stored in the memory and decides when the new path information and previously stored path information are substantially the same.
La présente invention concerne une machine autonome comprenant, d'une part des organes moteurs servant au déplacement de la machine sur une surface dans une zone, et d'autre part un système de navigation. Grâce au système de navigation, la machine suit une limite de la zone, conserve en mémoire des informations décrivant le parcours de la machine contre la limite, une comparaison lui permettant ensuite de constater qu'elle est revenue en point de la zone où elle est déjà passée. A cet effet, le système de navigation considère la partie la plus récente du parcours de la machine, la compare aux informations décrivant une partie du parcours préalablement conservée dans la mémoire, et constate éventuellement que l'information de parcours récente et l'information de parcours préalablement conservée en mémoire sont sensiblement identiques. |
