Here is another wearable robot designed to take load off of industrial workers. Hyundai Motor Group developed the vest-type wearable robot (VEX) for overhead tasks. It imitates human shoulder joint and doesn’t need any battery. The idea is to use this wearable robot to reduce fatigue and improve productivity of workers.
VEX weighs only 2.5kg and is worn like a backpack. Here is how it works:
The user places their arms through the shoulder straps of the vest, then fastens the chest and waist buckles. The back section can adjust in length by up to 18 cm to fit a variety of body sizes, while the degree of force assistance can be adjusted over six levels – up to as much as 5.5 kgf. The wearable vest with the polycentric axis combines multiple pivot points with multi-link muscular assistance to function without battery.
