Title (EN) CABLE-DRIVEN FOUR-BAR LINK LEG MECHANISM
(FR) MÉCANISME DE JAMBE DE LIAISON À QUATRE BARRES ENTRAÎNÉ PAR CÂBLE
Abstract:
(EN) A leg mechanism includes an articulated leg system (100), a passive device (130) and a cable (134). The articulated leg system (100) has a leg portion (128). The passive device (130) is coupled to the articulated leg system and is configured to apply a first force to a portion thereof. The cable (134) is coupled to the articulated leg system (100) and is configured to apply a second force, in opposition to the first force, to a portion thereof. When the cable (134) is drawn away from the articulated leg system (100), the second force moves the leg portion (128) in a first direction. When tension is released from the cable (134), the passive device (130) exerts the first force so as to move the leg portion (128) a second direction that is opposite the first direction.
(FR) L'invention concerne un mécanisme de jambe comprenant un système de jambe articulé (100), un dispositif passif (130) et un câble (134). Le système de jambe articulé (100) comporte une partie jambe (128). Le dispositif passif (130) est couplé au système de jambe articulé et est conçu pour appliquer une première force à une partie de celui-ci. Le câble (134) est couplé au système de jambe articulé (100) et est conçu pour appliquer une seconde force, en opposition à la première force, à une partie de celui-ci. Lorsque le câble (134) est tiré à l'opposé du système de jambe articulé (100), la seconde force déplace la partie jambe (128) dans une première direction. Lorsqu'une tension est libérée du câble (134), le dispositif passif (130) exerce la première force de manière à déplacer la partie jambe (128) dans une seconde direction qui est opposée à la première direction.
