Abstract

La présente invention concerne un appareil d'articulation de robot utilisant des câbles et un système d'articulation de robot modulaire utilisant des câbles. L'appareil d'articulation de robot selon la présente invention comprend : un cadre principal; un module d'articulation disposé de façon rotative sur le cadre principal pour déplacer une articulation; des premier et second câbles ayant chacun une extrémité reliée au module d'articulation; un premier module d'entraînement de câble relié à l'autre extrémité du premier câble pour tirer sur cette dernière de telle sorte que le module d'articulation tourne dans le sens horaire; et un second module d'entraînement de câble relié à l'autre extrémité du second câble pour tirer sur cette dernière de telle sorte que le module d'articulation tourne dans le sens antihoraire, les premier et second modules d'entraînement de câble tirant sur les premier et second câbles, respectivement, pour contrôler la rigidité des mouvements d'articulation du module d'articulation au moyen de la tension créée par les premier et second câbles, et correspondant aux premier et second modules d'entraînement de câble s'entraînant dans les directions opposées, le module d'articulation déplace une articulation dans le sens horaire ou antihoraire en raison de la puissance de traction de l'un quelconque parmi le premier câble et le second câble. En conséquence, un mouvement dans l'articulation peut être généré par structuration d'une articulation au moyen d'une combinaison de tensions de deux fils de câble, comprenant le premier câble et le second câble formant une paire, et la tension appliquée au module d'articulation permet à la rigidité d'articulation structurelle d'être contrôlée.
