New NASA Robot Could Help Paraplegics Walk

I hate to be a pessimist, but it's my understanding that there's no real technological hurdle that needs overcoming in terms of getting a strength-assist exoskeleton.

Sure, some fine tuning. You know, making sure that it doesn't break the user's bones and all that. But nothing too technically complicated.

It gets slightly more complicated if you're wanting a pure machine-brain interface rather than it being controlled through some other arrangement. But we've seen stuff like this already. The brain adapts well to new stimuli, and I'm sure somebody will get all the kinks worked out of that at some point not too far away.

The problem, as far as I'm aware, is with the power source. Battery technology has been stuck at roughly the same point for decades now. The weight to power-concentration ratio just isn't there.

So unless this story is actually about Nasa figuring out coke-bottle-sized cold fusion, then (unfortunately) go read this post's subject line.
