NASA has announced that it’s working on the X1, an exoskeleton that will give users improved mobility and strength. The project, which is the result of a partnership with the Florida Institute for Human and Machine Cognition, aims to help astronauts maintain muscle strength in low-gravity, low-resistance environments, but also hopes to assist paraplegics to walk. It’s one of many exoskeletons we’ve seen over the years — France’s Hercule project is already at an advanced stage — but with the heft of NASA behind it, the X1 looks as though it may have a good chance for success.
