摘要: This paper describes a powered lower-limb orthosis that is intended to provide gait assistance spinal cord injured (SCI) individuals by providing assistive torques at both hip and knee joints. The has mass of 12 kg capable maximum joint 40 Nm with ranges motion from 105° flexion 30 ° extension 105 10 hyperextension, respectively. A custom distributed embedded system controls the power being provided lithium polymer battery which provides for one hour continuous walking. In order demonstrate ability assist walking, was experimentally implemented on paraplegic subject T10 complete injury. Data collected during walking indicates high degree step-to-step repeatability trajectories (as enforced orthosis) an average speed 0.8 km/hr. electrical required each approximately 25 27 W, respectively, contributing 117 W overall device video corresponding aforementioned data included in supplemental material.
