Comparative analysis of energy saving effect of passive exoskeleton designs

Abstract

Nowadays, exoskeletons have a wide range of application in many fields. Among various types of exoskeletons, passive exoskeletons have become a major development field in exoskeleton device due to their lightweight and simple structure characteristics. This study provides an analysis of an ankle passive exoskeleton and a full lower limb passive exoskeleton design on their respective energy-saving effect during walking. The two selected designs both represent common approaches within the fields of ankle and full lower limb exoskeleton. Through a comparative evaluation of the structures and energy-saving methods of the two designs, the study validates the effectiveness of both designs. Drawing from the characteristics of the designs and comparative analysis, the study discusses the performance and limitations of both designs and outlines potential improvement and applications of both designs. Base on the analysis and the findings, the study aims to contribute to further advancement of passive exoskeleton design and offers some suggestions for its development.
