[CNN] Paraplegic College Student Walks With Exoskeleton - Page 2

post #11 of 18
In my opinion the idea of using servos located on the joints is the big obstacle for exoskeletons.

Because essentially the bottleneck is with how much power can a servo exert while online occupying an area of very small volume.

There are two directions I see this tech going. One is electroactive polymers which contract when an electrical charge is passed through them (this technology is the inspiration behind the crysis nanosuit). That way you can bundle them into fibers like your muscles and then just construct them so they literally function like the muscles in the pilot's body.

The second is servos which are located in the back and use wires to manipulate arms and legs, by moving the servos to the back of the suit you can make larger and more powerful servos. But they still hit the wall when it comes to size and power efficiency.

A possible third is a hybrid between the other two, use muscular bundles of electroactive polymers attached to the servos on the back, increasing the total strength capacity of the suit tremendously. But it would also be relatively power hungry.

The tech is amazing, and I'm glad such technology is coming out. But let me be the first to say this kid was the wrong choice.

I understand you should be forgiven for your mistakes and yadda yadda, but how about a victim of a drunk driver getting the chance to walk again instead of a drunk driver?

This is coming from a kid with a DUI. My stupidity could have cost myself or someone else their life, and I can tell you right now the only reason why this is a tear jerking story instead of one of uprage is because he managed by the grace of god not to hit someone else on the road and kill them.

I have been thinking about this kid all day. I at first was "o.O your choice of candidate is a self-inflicted DUI victim?" but I thought about his quality of life. Its a prison sentence that is more than likely never to be parolled, figuratively speaking of course. Had he injured someone walking down the road, like a mother, then he deserved it of course, but he didn't. I have to look at the facts of this case. He apparently is graduating with Honor's from Berkeley.

I suppose, that in his case being related to the school (this was a Professor of the University's design) it was probably a fitting move. There were possibly physical attributes that had to have been met, such as upper body strength, or height, or how much motor function he still did have. There could have been vast reasons this one kid was picked up.

I do agree, there are plenty of members of society who are way more deserving and we will probably see some of them getting something like this in the future, but as this was just the beginning, I think that it was pretty nice of the school.

I think these arguments about whether the kid was "deserving" or not are distracting from the important part of the story, the exoskeleton. Everyone has made at least one big mistake in their life and while there may well have been a more deserving person I don't its OCN's place to make that call.

Anyway, pretty cool, we need some real advances in battery technology before these things will be practical.

I do agree, although this thread probably won't get much more traffic, lets keep it on topics smile.gif

it's not like MIT is any more prestigious than Berkeley. If anything, Berkeley has a greater amount of resources than MIT due to the sheer number of high quality professors there. UCB has around double the staff of MIT if I'm not mistaken.
