Mike Murphy, writing for Quartz: Ford's cars are getting closer to driving themselves, but they still need humans to build them. And because people aren't quite as durable as robots, it's trying to make those jobs easier by developing a suit with Ekso Bionics that takes the stress out of working long hours on a car assembly floor. Ekes, founded in 2005 in California, builds exoskeletons, essentially robotic assistive systems that people strap into to make walking, lifting, and standing easier. It's worked with the US military to build suits for soldiers. The system Ekso developed with Ford, called the EksoVest, doesn't use any motors to make working on factory lines less stressful, and it's nothing like what you see in movies, as it simply uses hydraulics to redistribute weight so that workers can comfortably raise their arms above their heads for extended periods of time. The suit can be worn by anyone from 5 ft to 6 ft 4 inches tall, and can provide lift assistance up to 15 pounds per arm. Some assembly-line workers at the average Ford plant lift their arms 4,600 times a day -- or about 1 million times a year, the company said.
