Autonomous Control of Lower Limb with Prosthetic Part for Paraplegic Individuals through Voice

D. Priyadharshini, R. Subhasree

Abstract


The prosthetic part of powered lower-limb orthosis that is intended to provide gait assistance to spinal cord injured (SCI) individuals by providing assistive torques at both hip and knee joints.. A custom distributed embedded system controls the orthosis with power being provided by a lithium polymer battery which provides power for one hour of continuous walking. Data collected during walking indicates a high degree of step-to-step repeatability of hip and knee trajectories and an average walking speed of 0.8 km/hr. The electrical power required at each hip and knee joint during gait was approximately 25 and 27 W, respectively, contributing to the 117 W overall electrical power required by the device during walking.
