Full-blown automation may be the future of manufacturing, but we’re not there yet. While some machines have taken over the more painstaking tasks on the factory floor, humans still play a vital role in the production line. But often, it isn’t easy work. Tasks typically require being on one’s feet, and some even involve making repetitive arm motions up to 4,600 times a day or one million times a year. Now, some 75 EksoVest Exoskeletons, built by Ekso Bionics, have been distributed to employees at 15 Ford factories across the world. The exoskeletons don’t have motors, or even batteries, but provide “passive assistance” in the form of arm support from five to 15 pounds. By giving more arm support the higher a person reaches, the device takes strain off of the arm muscles.
