Here is another wearable robot designed to take load off workers and increase their productivity. Hyundai Motor Group developed vest-type wearable robot Vex that assists human workers by imitating human shoulder joint:
At 2.5kg, VEX weighs 22-42% less than competing products and is worn like a backpack. 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 VEX is expected to go into commercial production in December.
