Lightweight Exoskeleton Gives Paraplegics New Legs

SAN FRANCISCO A Berkeley company on Thursday introduced a battery-powered exoskeleton to get paraplegics out of their wheelchairs and walking on their feet.

Called eLEGS, the exoskeleton consists of a robotic frame controlled through crutches. The crutches contain sensors; putting forward the right crutch moves the left leg, and vise versa. The eLEGS battery can enable a user to walk for one day before it needs to be recharged, according to the products developer Berkeley Bionics. (See video below.)

With every step I feel more confident, and its truly liberating, said Amanda Boxtel, a paraplegic for 18 years who demonstrated the eLEGS exoskeleton at a press conference Thursday. Im usually in a wheelchair and 4 feet tall, staring up at peoples nostrils. Now Im able to look at the world.

Exoskeletons wearable, artificially intelligent bionic devices have primarily been developed for military usage to enhance soldiers strength and endurance in the battlefield. In the medical industry, doctors are also studying exoskeleton applications to assist the physically disabled.

The implications of exoskeletons in the health field go beyond giving paraplegics robotic legs. They could also teach people to learn how to walk on their own again. Currently, rehabilitation centers use much larger, stationary and extremely expensive devices to assist with temporary walking. (Wired.coms Tim Carmody points out that Getting time on these devices is like getting telescope time for an astronomer.)

Being able to walk with an exoskeleton enables users to do rehabilitation anywhere and anytime and that could be especially beneficial to people who are recently injured, Boxtel says in the video below, because they can begin load-bearing rehabilitation exercises while they still have the muscle memory for walking.

Theres huge therapeutic benefits for this device that will then become a preventative measure in the long term because our bodies are meant to be walking upright and moving, Boxtel said.

Berkeley Bionics based the eLEGS exoskeleton design on Lockheed Martins Human Universal Load Carrier (HULC) exoskeleton, a system designed to help military soldiers traverse through rough terrain without injuries.

Berkeley Bionics modified the HULC to make the eLEGS extremely user friendly with a Velcro strap, backpack-style clips and shoulder straps; anybody should be able to slip it on and off in a minute or two. The eLEGS will fit most people between 5′ 2″ and 6′ 4″, weighing 220 pounds or less, and Berkeley Bionics said it was especially important to make the exoskeleton thin, lightweight and very quiet when operated.

Today Im going to rekindle a hope among [those with] spinal cord injuries, said Eythor Bender, CEO of Berkeley Bionics. [eLEGS] will help people to get out of wheel chairs, stand up, walk, sit down and do other things as we develop it forward.

The eLEGS will initially be available at select rehabilitation centers starting July 2011, according to Bender.

The company also plans a mobile version of eLEGS for home use. People will be able to strap it on in the morning and use to walk around as they go about their days, according to CEO Eythor Bender.

I added pics. The technology seems to work quite well. I should watch the vids on the link page.

EDIT: The vids won't load for me for some reason.

Now, if there were only some way to conceal it and lose the crutches...

Give 'em 5-10 years.

Note, my lighthearted jab at the design was not meant to take away from the fact that technology can do some marvelous things!

Still quite early days, the basics are there, it shouldn't be too much of an engineering chore to get it slimmed down a bit

Why are presentations like this always done on a stage in a darkly lit room?

Perhaps this thread should be labeled "NSFW"

EDIT: Now I get it. At first I thought people in your office were laughing. It's the subjects of the pic that are loling.

Because it makes everything much easier to see. If everything was bright, it would be hard to make out what is happening on stage. When everything is dark and the light is concentrated on in one small spot on the stage, it is much easier to differentiate what is happening.

The looks on their face,I can only imagine how they feel.Its kind of ironic how a designed killing machine can be used in a whole opposite direction.

Anyone else see what I see?

I had the same thought last night. I'm not anti-military, but just the same......

I still can't DL the vids from wired.com, but YouTube has something similar:

Very cool
