Ever since I was a kid, and I saw one in a cartoon, I’ve been fascinated with exoskeletons. Naturally, esp. as a kid, I was most interested in the ones that could give you superhuman strength. They can be as simple or as elaborate as you want. When I was still a child, I envisioned one that was just a suit of titanium armor with simple pulleys to make the wearer stronger. Then I came up with the idea of adding hydraulics to the limbs of the exoskeleton to make the person stronger still. (BTW, when I was still an adolescent, I thought to myself that probably even the suit of titanium armor by itself might be a “simple” machine, much in the same way that a fulcrum is a simple device. So the suit of armor might make the person a stronger, a little at least 
.)
For the longest time, I have wondered why no one bothered to make an exoskeleton. After all, surely the pulley one would be simple enough to make–and there might be comercial market for it too, who knows. Then more recently I heard that UC Berkley finally did make one–and an elaborate robotic one on top of that. This got me started on thinking of some of my ideas for exoskeletons from my childhood, and after. Actually, one idea of mine seems to also have been taken up by someone: an exoskeleton that protects against bear attack! I kid you not. As a child, probably before this other guy came up with the idea, I thought of using the exoskeleton for superhuman strength and bear attack! I never bothered to get my idea copyrighted, so I guess I can’t complain. But I thought, in the interest of science, I might share some of my original ideas for it…
I have seen this bear attack suit that this Canadian man made on TV. And it does look kind of big and bulky. As a child I envisioned a superhuman/bear-attack suit (that was bulletproof too, BTW) that was sleek and thin. I might be wrong, but I figured this could be accomplished by a kind of 3-D net that resembled 3-D cartesian coordinate system. It is hard to explain in words alone. But basically, I figured that each one of these cells could work together to absorb the shock of a bear attack, etc. Then of course when the bear saw his blows had no effect and you were stronger than him too, he would think twice about attacking humans 
(thus I envisioned these could be handed out to park rangers, etc.). I also envisioned making this 3D netting out of some strong material, like Kevlar.
Well, one more quick note. I recently thought of a good addition to my above idea. More recently I found that it has become possible to make man-made spider silk. As many of you may know, spider silk (literally the thread spun by spiders) is one of the strongest, yet lightest, materials known to man. So, spider silk added to my above Kevlar idea might have all the strength, along with the thin, sleek design I envisioned as a child. As I’ve said, it is tool late for me to copyright any of this. But in the interest of science, I would still like to hear people’s input on my, and their own ideas for exoskeletons 
. As I’ve said, I really think there might be a use and market for these some day.
