Exoskeleton for Resistive Exercise and Rehabilitation

X1 is a robotic exoskeleton developed by NASA Johnson Space Center and the Florida Institute for Human and Machine Cognition (IHMC). Produced using Robonaut technology, X1 was initially designed as a human assist device to allow people with paraplegia to walk again. This video shows a man in a wheelchair using the X1 to stand and walk across a room. NASA is exploring space applications for the exoskeleton, such as amplifying astronaut strength, or even as exercise devices for long duration missions. When used for resistive exercise, the exoskeleton provides real-time feedback. Worn over the legs with a harness that reaches up the back and around the shoulders, X1 has ten degrees of freedom, four joints at the hips and the knees, and six joints that allow for sidestepping, turning and pointing, and flexing the foot.
