Hyundai Motor Group has developed the new Vest EXoskeleton (VEX), a wearable robot created to assist industrial workers who spend long hours working in overhead environments. The VEX enhances productivity and reduces fatigue of industrial workers by imitating the movement of human joints to boost load support and mobility. The wearable vest has a polycentric axis—combining multiple pivot points with multi-link muscular assistance—to function, eliminating the need for a battery.
