 The ELEG exoskeleton is a novel semi-passive lower limb exoskeleton designed to provide assistance for workers performing long-term static squatting tasks. It uses motorized tuning of the assistive squatting height to maximize its effectiveness. Additionally, it incorporates inertial sensors and an electromagnetic switch to measure the tilt angle of the thigh and adjust the squatting height respectively. Experimental results showed that the exoskeleton reduced muscular activity and had no significant impact on the normal gait of users during walking. Overall, the ELEG exoskeleton has the potential to be effective in reducing muscular strain on long-term continuous squatting activities.
