Exoskeleton for the human arm, in particular for space applications
First Claim
1. An arm exoskeleton for acquiring data representative of the movements of arm joints of a human body and/or exerting torques to said arm joints, the exoskeleton comprising a sleeve for wearing on at least one arm of a human person so as to provide a moving system of exoskeleton joints, said sleeve comprising a first subassembly “
- shoulder exoskeleton”
having at least six exoskeleton joints associated with a shoulder joint of said human body, a second subassembly “
elbow exoskeleton”
comprising at least four exoskeleton joints associated with an elbow joint of said human body, and a third subassembly “
wrist exoskeleton”
comprising at least six exoskeleton joints associated with a wrist joint of said human body, and actuating units for controlling said first, second and third subassemblies, such that said first, second and third subassemblies are mechanically dissociated so as to be capable of being controlled individually by said actuating units.

Abstract
The invention relates to an arm exoskeleton comprising a moving system of joints placed in parallel with the joints of the human arm, the exoskeleton comprising a shoulder exoskeleton, an elbow exoskeleton, and a wrist exoskeleton. In all, the exoskeleton has sixteen joints providing sixteen degrees of freedom. A support worn on the torso of a human operator comprises a rigid front plate and a rigid back plate. The shoulder exoskeleton has its proximal end fixed to the front plate, whereby the front plate provides a fixed reference for all movements of the exoskeleton, and the wrist exoskeleton is fixed to a rigid glove worn on the hand of the operator. Active joints are controlled by flexible cable tendons bridging the exoskeleton, said tendons themselves being actuated by control units disposed on the rigid back plate. Inflatable cushions prevent the wrist exoskeleton and the shoulder exoskeleton from moving relative to the arm of the operator. The invention is applicable in particular to remotely controlling a robot in space.
