Abstract[English]
A compensation device (100) is arranged to provide assistive forces at an operator's hip joint in a passive lumbar exoskeleton (10). The compensation device (100) includes an assistive torque assembly (102) with a thigh link (104) that is rotatably connected. The assistive torque assembly (102) features a torque output mechanism (106) that moves an elastic mechanism (112) and includes an assistive regulation device (108) configured to preload a specific level of assistive torque supplied by the elastic mechanism (112). The torque output mechanism (106) contains an angular offset mechanism (114) that adjusts the angular engagement of the assistive torque, along with a torque profile modifier (115) that modifies the rate of deflection of the elastic mechanism (112). An exoskeleton (10) includes the compensation device (100), such that the compensation device (100) is configured to be worn by an operator through a physical human–robot interface (pHRI) (14).[French]
Un dispositif de compensation (100) est aménagé pour fournir des forces d'assistance à l'articulation de la hanche d'un opérateur dans un exosquelette lombaire passif (10). Le dispositif de compensation (100) comprend un ensemble couple d'assistance (102) avec une biellette de cuisse (104) qui est reliée rotative. L'ensemble couple d'assistance (102) comprend un mécanisme de sortie de couple (106) qui déplace un mécanisme élastique (112) et comprend un dispositif de régulation d'assistance (108) conçu pour précharger un niveau spécifique de couple d'assistance fourni par le mécanisme élastique (112). Le mécanisme de sortie de couple (106) contient un mécanisme de décalage angulaire (114) qui règle la mise en prise angulaire du couple d'assistance, conjointement avec un modificateur de profil de couple (115) qui modifie la vitesse de déviation du mécanisme élastique (112). Un exosquelette (10) comprend le dispositif de compensation (100), de telle sorte que le dispositif de compensation (100) est conçu pour être porté par un opérateur par l'intermédiaire d'une interface homme-robot physique (pHRI) (14).
