Title
(EN) ROBOTIC WORK TOOL, SYSTEM, AND METHOD FOR OPERATION THEREOF
(FR) OUTIL DE TRAVAIL ROBOTIQUE, SYSTÈME ET SON PROCÉDÉ DE FONCTIONNEMENT
Abstract
(EN)
A method for operating a robotic work tool (1) comprising a sensor for detecting a boundary wire (3) demarcating a work area (2). The method comprises the steps of detecting (9) at least a partial crossing of the boundary wire (3), allowing (12) a crossing of the boundary wire (3) by an offset, switching (8) between a first offset setting and at least a second offset setting of the work tool (1) based on one or more events (7). A robotic work tool (1) comprises a controller for controlling the operation of the robotic working tool (1). The controller is configured to: control the work tool (1) to operate within the work area (2), determine whether the work tool (1) crosses the boundary wire (3), allow a crossing of the wire (3) by the offset, and switch (8) between at least two offset settings stored in the work tool (1).

L'invention concerne un procédé de fonctionnement d'un outil de travail robotique (1) comprenant un capteur pour détecter un fil de délimitation (3) délimitant une zone de travail (2). Le procédé comprend les étapes consistant à détecter (9) au moins un croisement partiel du fil de délimitation (3), permettre (12) un croisement du fil de délimitation (3) par un décalage, commuter (8) entre un premier réglage de décalage et au moins un second réglage de décalage de l'outil de travail (1) sur la base d'un ou plusieurs événements (7). Un outil de travail robotique (1) comprend un dispositif de commande pour commander le fonctionnement de l'outil de travail robotique (1). Le dispositif de commande est conçu pour : commander le fonctionnement de l'outil de travail (1) à l'intérieur de la zone de travail (2), déterminer si l'outil de travail (1) franchit le fil de délimitation (3), permettre un croisement du fil (3) par le décalage, et commuter (8) entre au moins deux réglages de décalage stockés dans l'outil de travail (1).
