Firstly, it's too bad the military-industrial climate in the US means that the first "application" of such technology is towards "the soldier of the future". I see such a "strength-enhancing" technology as more useful in contexts like warehouse management, replacing forklifts, rather than soldiering, where I'd think that "small, quick and light" would be virtues. As mentioned in other comments, "helping old people" is how they think of this kind of thing in Japan. (Though it makes me laugh to think about a grandfather type wearing such a gigantic exoskeleton to do the groceries..)
Anyways, the real point of my post was to think about safety issues. Every time I see exoskeleton technology, it makes me think about the fact that acceleration-based positive feedback control has a tendency to "explode" if you're not very careful. I'd be afraid of putting such a suit on for fear of it ripping my arm off if something malfunctioned. What kind of safety restrictions are in place on this thing?
By positive feedback, I mean: In a typical control situation, you'd have sensors that can tell you, 'hey you're pulling really hard on the arm right now and there is a lot of resistance, so stop.' However in this case, I'd imagine the logic is more like 'hey you're pulling really hard on the arm right now, and there is a lot of resistance, meaning the guy needs more help, so pull harder!'
