Abstract

La présente invention vise à permettre à un opérateur de régler facilement une valeur de temporisation d'un temps de veille déclenché par un verrouillage, pour chaque action lors de la mise en œuvre d'un apprentissage autonome d'un robot. Un mode de réalisation de la présente invention concerne un dispositif d'apprentissage de robot comprenant : une unité de création de tâches (102) qui crée des tâches, chaque tâche se présentant sous la forme d'informations associées à une action mise en œuvre par un robot relativement à un objet cible, sur la base d'une entrée de fonctionnement effectuée par un opérateur, et qui définit dans chaque tâche des informations associées à un premier point, qui est un point de passage avant qu'un point cible de l'action ne soit atteint, et/ou à un second point, qui est un point de passage après que le point cible a été atteint ; et une unité de réglage de verrouillage (115) qui définit une valeur de temporisation d'un temps de veille pour amener l'activité du robot à se mettre en veille lors de l'atteinte du premier point et/ou du second point définis dans la tâche, sur la base d'une entrée de fonctionnement effectuée par l'opérateur.
