In this paper, a technical method of reducing torque load of exoskeleton device, with using of a gravity compensator based on a torsion bar, for human leg joints, is proposed. Design and structure analyses and also performance test were performed to estimate and to measure the characteristics of the torsion bar. On the basis of design and structure analysis, a new light and compact exoskeleton device has been developed. For the purpose of lightening and optimizing thickness of the links, FEM analysis has been performed.
