DIY Working Iron man Answered

Here's an idea that someone can use for the robot contest if they want, I would but I just don't have the money.

You buy 4 linear actuators (such as the ones here: http://www.firgelliauto.com/product_info.php?cPath=91&products_id=7

And you attach one to each limb, giving you super strength.

I just don't have like 500 dollars to spend


you know, its funny that you say that, because this summer i am gonna make a suit of armor that i saw off of the video game Technic Pack. i know that i am taking a shot into the darkness but with some modifications, i could turn a fictional suit of armor into an actual nanosuit armor!

I doubt that there's much "new" technology in "Iron man." The powered exoskeleton is quite an old idea. Waldo was a Robert Heinlein short story published in 1942, and is where the term "Waldo" for assorted types of remote manipulators originated.
Starship Troopers, with full fledged military powered armor] was written in 1959.

As you and others point out, relatively high powered actuators are pretty easy to get. Size is a problem (There are over 600 muscles in the human body.) Fine control is more of a problem, and POWER for typical actuators is a BIG problem (along with heat dissipation.)

Most fictional "enhanced humans" have obvious and hilarious mechanics and physics problems long before you get to that level of detail. You've already pointed out the problem with attaching super-powerful things to biological bases, and I always used to crack up when The Six Million Dollar Man would reach up and bend some steel girder DOWNWARD. (for an interesting experience, compare and contrast "The 6 Million Dollar Man" TV series with the book it was based on [http://en.wikipedia.org/wiki/Cyborg_(novel) (Cyborg, by Martin Caidin)].

to be quite honest, I think I can do better than that. To make what they made I think it'd only cost ~800-1000 dollars, to build a better one with super fingers instead of hooks could be made for the same price, but it wouldn't include any armor (I'm not going to go and get shot)

to be quite honest, i dont think you can do better... thats the military, there generally better funded, and more knowledgeable than a teenager.. no offence, i just think the military is better than a kid (including me). just remember how much the suit alone would weigh. those linear actuators have to be pretty strong to lift the metal, plus what its lifting

I'm just saying it looks half... uhhh. butt. They got lazy at the end, putting on a hook instead of fingers. The battery life is no problem, lugging a 20 pound battery pack could power that whole suit for ~2 hours, and with the extra strength it doesn't matter. Years of complex development and programming? That looks like it could easily be configured using even an arduino. Sure, the military is more funded, but that doesn't mean they necessarily do better.

Suprisingly, it's not too hard to get actuators etc easily powerful enough...

I had my own idea similar to this, soemday, except bigger and talking about several tonnes of equipment and actuators capable of lifting 30tonnes..

I might actually build one this summer if I make enough money, at least for one arm as a proof of conecpt.

they sell 400 pound pull ones for only 130$ The only thing that I'd be scared when building one is the strength of the structure. I'd have like steel bars around my arm, but 400 pounds could easily break bone... I think.

Yeah, you know you can break someones arm with three pounds of pressure in the right place? I would suggest something like power assist steering, the amount you try is the amount it assists, iamgine picking up a small item only to throw it half a mile by accident...

what I was thinking was that it has pressure sensors inside, and (being controlled by a micro controller) it always wants to keep you in the center of all the sensors. So as you move the whole system moves with you trying to equalize the sensors and keeping you in the center.

I'd have to have some built in saftey mechanism, biggest fear is that if I grab something that's heavier than me and pull then it'll hurl me into it. My weight only being 100 pounds doesn't help (mind you I'm not weak, put I wouldn't say i'm strong, I'd say I'm ~average strength for someone in our school). Maybe a maximum speed for the actuator to operate? I could just see myself breaking my nose or something like that. Anybody have any ideas for protection for that?

Well, I'd say you can easily enough control the speed of actuators... The other problem would be putting stresses on the body, it would basically need to be able to completely support itself or there'd be falings over going on...

if I do build one, at what extent do i have to build it. Let's say I build one for my right arm, then I have to reinforce my arm with something such as steel, then I have to reinforce my torso. Do I have to reinforce anywhere else, where does all of the pressure go? Another question, how much stronger is a carbon fiber rod compared to a same size steal rod?
