Abstract[English]
A method for assigning collision clearance distances for a robot picking up objects in a collision free manner is provided. A virtual environment is simulated that includes representations of the robot, a first workspace that indicates the objects, and a second workspace. A simulated path taken by the robot to pick up a virtual representation of an object from the first workspace and place the object at the second workspace is generated. Based on the simulated path, a first and a second collision clearance distances are received such that the robot avoids a first and a second edge of the first workspace, where the second collision clearance distance is different from the first clearing distance. Based on the simulated path and the first and second collision clearance distances, the robot is controlled to pick up the object from the first workspace and place the object at the second workspace.[French]
L'invention concerne un procédé d'attribution de distances de dégagement de collision pour un robot saisissant des objets d'une manière sans collision. Un environnement virtuel est simulé, il comprend des représentations du robot, un premier espace de travail qui indique les objets, et un second espace de travail. Un trajet simulé pris par le robot pour saisir une représentation virtuelle d'un objet à partir du premier espace de travail et placer l'objet au niveau du second espace de travail est généré. Sur la base du trajet simulé, des première et seconde distances de dégagement de collision sont reçues de telle sorte que le robot évite un premier et un second bord du premier espace de travail, la seconde distance de dégagement de collision étant différente de la première distance de dégagement. Sur la base du trajet simulé et des première et seconde distances de dégagement de collision, le robot est commandé pour saisir l'objet à partir du premier espace de travail et placer l'objet au niveau du second espace de travail.
