Title (EN) COLLABORATIVE ROBOT
(FR) ROBOT COLLABORATIF
Abstract:
(EN) A collaborative robot employs low ratio drives for three or more axes of movement, such as three primary axes. An arm assembly may be mounted to a support for movement along a vertical linear axis, and the arm assembly may include first and second arm links that are each rotatable about vertical axes, e.g., such that the arm links move in a horizontal plane. Low ratio drives may be used for movement along the vertical linear axis and the rotary axes for the first and second arm links. Feedforward and feedback control may be employed to control the movement of the arm assembly and arm links, and feedback torque components may be limited to 25% or less of the maximum drive torque.
(FR) La présente invention concerne un robot collaboratif utilisant des entraînements à faible rapport pour trois axes de mouvement ou plus, par exemple trois axes principaux. Un ensemble bras peut être monté sur un support pour un mouvement le long d'un axe linéaire vertical, et l'ensemble bras peut comprendre des première et seconde liaisons de bras qui sont chacune rotatives autour d'axes verticaux, par exemple, de telle sorte que les liaisons de bras se déplacent dans un plan horizontal. Des entraînements à faible rapport peuvent être utilisés pour un mouvement le long de l'axe linéaire vertical et des axes rotatifs pour les première et seconde liaisons de bras. Une commande prédictive et de rétroaction peut être utilisée pour commander le mouvement de l'ensemble bras et des liaisons de bras, et des composantes de couple de rétroaction peuvent être limitées à 25 % ou moins du couple d'entraînement maximal.
