I still think companies have experimented with devices that induce muscle function by eletrical currents, but because of the liability thrown onto the company dis encourages them to pursue it (imagine if someone got a heart attack).

the dr. that invented it is missing his right arm/hand. i figured he would invent something better than that claw.

This is GREAT news, Horray for science.
Paraplegics everywhere must be jumping for joy!
Oh wait... clapping for joy.

After the last post about the theft of milk, I was expecting something at least a little NSFW... now I`m bummed.

@Angilion, I agree, the basic technology has been around for years but there have been refinements in both materials and in the human/machine interface software which controls the prostheses so that movement is smoother and easier for the wearer to control.

Yep. Every single fecking day. We just get to it before you notice it, normally. Cleaning up now, soz.

The acceleration needed to jump 50` is the same as as it would be for landing. You would have to leave the ground going about 38 mph, and you would land at the same speed. If you could squat 2` to start your jump, you would have to accelerate at about 25Gs to jump 50`. If your legs compressed 2` to absorb the shock of landing, you would again experience about 25Gs. If you and the suit weigh 400 lbs., this would exert a force on the ground of about 10,000 lbs. -- about the same as a UPS truck. This would only last for about 0.07 sec., but it would be enough force to really mess you up. You would need rockets or jets to accelerate you more gradually on takeoff and to brake you more gently on landing.

angilion, it is possible to survive a 50ft fall now. you really have a 50/50 chance of surviving it without any protection. but, there are materials that can decelerate you on impact. this is how stunt men survive long falls. granted, these are usually giant materials and usually balloons, but tell me that sometime in the future we will not find a way to condense this deceleration into some kind of pad that may be attached to the machine. if not, then you could always have built in hydrolics that decelerate you more slowly on impact than the exoskeleton that surrounds your limbs.
but my biggest argument is this: we are fighting about stuff that for now is science fiction anyway, my argument can neither be founded nor unfounded at our current state.

now if they could make one that literally breaks the ground!

Not who, what. You canna break the laws of physics. The only way you can fall 50 feet without breaking is if you can decelerate before you hit the ground. The exoskeleton might be made strong enough to withstand the impact, but the person inside it isn`t. I`m not sure how well you could withstand the take-off force needed to jump 50 feet high, but the force of impact is definitely going to break you. You`d need some kind of repulsor beam to start decelerating you some way off the ground.

I COULD never walk again. no offence to this guy or the company, but there are a lot of paraplegic`s, even t10`s that walk with regular leg braces(non motorized/powered). check out http://parawalk.com/ and http://sci.rutgers.edu/index.php?

angilion, i was kidding man, did you not read the rest of my post? the thing is though, that if they had the ability to have us jump 50ft in the air, who`s to say by that time they will not also have the technology to to cushion the landing to a safe point as well.

I`m a fan of the prototype bionic exoskeleton developed by Raytheon. http://www.youtube.com/watch?v=Nhj3Z9o6t...

It may not change the world with this model, but like the guy said, its a good start.

Not until you mentioned it. I`ve just looked at it on How Stuff Works. Fascinating. Not as cyborg badass as cranial computers and artificial eyes, though.

This reminds me of a bionic hand that worked 95% of the time. It made me wonder... what happened in the other 5%? I hope no one died.

Won`t be long until all of our body parts are replaced by superior bionic versions. Can`t wait.

For badass cyborg stuff, I think you can`t beat the guy with no eyes who can see.

Computers in his brains, jack plugs in his skull, cameras on dark glasses feeding data through the jack plugs into his neural computers, which process it and feed it straight into his brain.

No word of a lie. The researcher who developed the system introduced it at a medical conference with a video of this guy driving a car. The quality of the vision sucks, but it sure beats no vision at all. That was some years back. No doubt it`s better now.

This isn`t an amazing revolution in technology. I doubt if there`s any new technology in it, let alone amazingly revolutionary new technology. Motion sensors aren`t new. Small computers aren`t new. Electric motors aren`t new. Leg braces aren`t new.

Fully functional bionic legs would require a much better understanding of the brain. To get the same functionality as natural legs, you`d need to use the same control system, i.e. your brain. So the system would need to intercept and interpret signals from your brain that would have moved your legs, then move the bionic legs the same way.

You may see that in your lifetime. Not soon, but maybe by the time you`re old.

it doesnt matter if they have leg muscles or not. if their spinal cord is damaged badly enough so that the signal from their brain cant get to their legs, they can`t ever walk again unaided by some type of technology. period.

Which would severely injure or kill you, either from the acceleration or, more likely, from the deceleration when you hit the ground a few seconds later.

The control method is the key difference with this. It`s easy to make a powered exoskeleton that amplifies the strength of a movement (the USA military is testing those now) but far harder when the person can`t make any such movement. Using shoulder movement to control powered exoskeleton legs is an ingenious workaround.

Maybe the woman`s issue is confidence in the kit. You have to move your body as if walking and trust the hardware to move your legs. If it fails, you`re going to fall on your face.

this is really amazing, now what I`m wondering is if eventually they can have different settings so that some how it can give their legs a minor work out so that some muscle can either develop or stay maintained. But this really is amazing I can`t wait to see it go further this is going to change a lot of lives. Go science and money going to good use :)

Now, I`m in support of a Biological approach to fixing these problems over mechanical... but when it`s something like a spinal injury, where a biological cure might not even be possible, it is ingenuity like this that is our future.

Humans can work miracles when they get their act together.

Hm... this may be a radical idea.. but maybe... we should spend less money fighting... and fund this thing.
