Abstract[English]
An upper-limb exoskeleton (100) includes a compensation device (102) and a control system (104). The compensation device (102) has an elastic mechanism (112) configured to generate assistive torque about a joint rotation axis (A1). An active regulation system (116) comprising a servomotor (136), a worm gearbox (142), and a cam (158) modifies a distance between a first bracket assembly (126) and a second bracket assembly (128) to preload assistive torque. A selector system (114) adjusts the compensation device (102) between an unlock mode (167), a lock mode (169), and a transparent mode (171). The control system (104) computes and regulates assistive torque via a microcontroller (202) using open-loop current control and receives commands from a remote controller (118). The method and system provide adaptive control of assistive torque, enabling real-time adjustment, mode switching, and torque computation for ergonomic support during upper-limb exertion.[French]
L'invention concerne un exosquelette de membre supérieur (100) comprenant un dispositif de compensation (102) et un système de commande (104). Le dispositif de compensation (102) comporte un mécanisme élastique (112) conçu pour générer un couple d'assistance autour d'un axe de rotation d'articulation (A1). Un système de régulation active (116) comprend un servomoteur (136), une boîte de vitesses à vis sans fin (142), et une came (158) modifie une distance entre un premier ensemble support (126) et un second ensemble support (128) pour précharger un couple d'assistance. Un système de sélection (114) règle le dispositif de compensation (102) entre un mode de déverrouillage (167), un mode de verrouillage (169) et un mode transparent (171). Le système de commande (104) calcule et régule un couple d'assistance par l'intermédiaire d'un microcontrôleur (202) à l'aide d'une commande de courant en boucle ouverte et reçoit des instructions provenant d'un dispositif de commande à distance (118). Le procédé et le système fournissent une commande adaptative de couple d'assistance, permettant un réglage en temps réel, une commutation de mode et un calcul de couple pour un support ergonomique pendant l'effort d'un membre supérieur.
