We are developing exoskeleton robots to realize human shoulder motion assistance for the physically weak. In this paper, we propose controller adjustment for the controller of the exoskeleton robot for human shoulder motion assistance. Motion assistance in the entire movable range of the exoskeleton is realized with a few teaching motion patterns using the proposed controller adjustment. Muscle activity (electromyography) during shoulder motion and motion error between desired user shoulder motion and the measured assisted shoulder motion are evaluated.

В середине 2004 года японцы намерены начать продажу первых коммерческих экзоскелетов — силовых роботизированных костюмов HAL-3. Эти машины создавались, в первую очередь, для инвалидов. Но и военные с интересом посматривают в сторону этой новинки.

An active ankle-foot orthoses (AAFO) is presented where the impedance of the orthotic joint is modulated throughout the walking cycle to treat drop-foot gait. During controlled plantar flexion, a biomimetic torsional spring control is applied where orthotic joint stiffness is actively adjusted to minimize forefoot collisions with the ground. Throughout late stance, joint impedance is minimized so as not to impede powered plantar flexion movements, and during the swing phase, a torsional spring-damper control lifts the foot to provide toe clearance. To assess the clinical effects of variable-impedance control, kinetic and kinematic gait data were collected on two drop-foot participants wearing the AAFO. For each participant, zero, constant, and variable impedance control strategies were evaluated and the results were compared to the mechanics of three age, weight, and height matched normals.We find that actively adjusting joint impedance reduces the occurrence of slap foot allows greater powered plantar flexion and provides for less kinematic difference during swing when compared to normals. These results indicate that a variable-impedance orthosis may have certain clinical benefits for the treatment of drop-foot gait compared to conventional ankle-foot orthoses having zero or constant stiff-ness joint behaviors.
