Ford is partnering with California-based exoskeleton maker Ekso Bionics to trial a non-powered upper body exoskeletal tool called EksoVest in two of the carmaker's U.S. plants. The goal is to lessen the fatigue factory workers experience in Ford's car manufacturing plants. Futurism reports: Designed to fit workers from five feet to six feet four inches tall, the EksoVest adds some 3 to 6 kilograms (5 to 15 pounds) of adjustable lift assistance to each arm. This exoskeleton is also comfortable enough to wear while providing free arm movement thanks to its lightweight construction. "Collaboratively working with Ford enabled us to test and refine early prototypes of the EksoVest based on insights directly from their production line workers," Ekso Bionics co-founder and CTO Russ Angold said in a Ford press release. "The end result is a wearable tool that reduces the strain on a worker's body, reducing the likelihood of injury, and helping them feel better at the end of the day -- increasing both productivity and morale." The U.S. trial, made possible with the help of the United Automobile Workers, has already demonstrated the wonders that the exoskeleton can offer in reducing fatigue from high-frequency tasks. As such, Ford plans to expand their EksoVest pilot program to other regions, which include Europe and South America.
