X1 Robotic Exoskeleton Helps Astronauts Exercise and Could Benefit Paraplegics on Earth

A lot of the technology we enjoy here on Earth started out as tech created for the space program. NASA has a very cool robot working on the International Space Station right now called Robonaut 2. New technology that has spun off from the Robonaut 2 program has been unveiled that could help astronauts exercise while in the weightlessness of space – and could possibly help paraplegics on Earth to walk again.

x1 robot exoskeleton

The technology is called the X1 robotic exoskeleton and was developed in cooperation with NASA and the Florida Institute for Human and Machine Cognition. The exoskeleton weighs 57 pounds and can be worn by humans to help assist or inhibit the movement of leg joints. By inhibiting movement, the exoskeleton could also provide resistive exercise.

The exoskeleton is worn over the legs with a harness that reaches up the back and around the shoulders. It offers 10° of freedom in the joints with four motorized joints at the hips and knees along with six passive joints that allow for sidestepping, turning, pointing, and flexing the foot. The system offers multiple adjustment points allowing the X1 to be used in a variety of ways. For instance, the exoskeleton could be used to help astronauts carry heavy gear on the surface of other planets and could possibly be adapted to military transport use here on Earth.

It's hard to deny the appeal of a space-bound robot like NASA's Robonaut 2, fears of subversion notwithstanding. The space agency and Florida's Institute for Human and Machine Cognition know it, and they want to put that technology into an exoskeleton with a nobler purpose than performing chores on space stations. The in-development X1 (not yet pictured) adapts the Robonaut's skills to a body-hugging frame with 10 points of movement that might give humans an assist when they need it the most. In space, the X1 could automate and add challenge to exercise for astronauts in low gravity, or provide the extra muscle for that fabled day we return to manned surface exploration. NASA envisions its exoskeleton having more grounded uses as well, such as rehabilitation for leg injuries or walking for those who never had the chance. Although we're not expecting a rapid turnaround knowing NASA's lengthy schedules, we might see the X1 in use sooner than most such products in the wake of a purposefully quick development cycle -- and, no doubt, a few interested customers here on Earth.
