Abstract

This paper presents an assistive lower-limb exoskeleton (ALEXO) for active walking assistance. The mechatronics design covering mechanical design, sensors selection and motor controllers are introduced. A 2-link model is built for dynamic analysis control purposes, upon which a trajectory tracking control method based on an improved computed torque control is proposed. This control method was tested with sensor data acquired from walking trials of a healthy subject, which validated the design and gait control of this exoskeleton.
