Can't help but think of Snake's bionic arm. This looks amazing!
I wonder if the feedback from the prosthesis is able to to be fed back to the nervous system so that those who use it can feel through it

There's no reason it couldn't eventually be done although stuff like that is still very much a work in progress, but there's other considerations that are worth mentioning. That arm needs a power source, and where are you going to get that? I sincerely doubt the current (horrifying) methods of siphoning power from the human body could power that arm now or in the foreseeable future, so you'll need to be hauling a likely very hefty power system of some sort for any reasonable battery life.

Make a hand crank generator and put it in the robot hand. Unlimited power.
Why replace the human hand? Why not make it better? If I ever lost a hand, I would want one with two disposable thumbs on each side and 7 fingers which can bend back completely.

You mean opposable? Unless you want thumbs you can just eject from the hand at will.
Holy shit, it look like Deus ex human.

I want a mechanic middle finger that can go-go-gadget out of my hand

sub dermal heat collection or extremely small turbines powered by blood flow

Oh whoops.
I mean, why not both?

Tiny nuclear power generator. Then go all out and build an ironman suit.
Or just a USB port somewhere. Or even better, a dynamo in the elbow, so by using your other arm you can just bend and straighten out the prosthetic arm for a while until it charges the batteries a bit.

I know you're probably not being serious, but small nuclear reactors are generally impossible.
Nuclear reactors heat up water to make steam which drives a turbine that generates electrical power.
How would you fit all of that in an arm, and how would you keep the radiation from killing you within hours?

I know :(
How about you put it all on a big trailer and tow it behind you with your prosthetic super legs™. The ironman suit would obviously contain the radiation. The people around you would be in trouble though...
In reality the best thing you could do is a battery pack good enough for 10-20 hours of operation with universal charging options like charging it while in your car through the 12 volt socket, or through inductive charging. Just the motion of you moving around with one of these prosthetic arms on could be used to charge it but I don't think it would produce anywhere near enough power to be useful for driving high torque motors.
Honestly there really isn't a viable way to power these things long term, yet. Perhaps in the future they will be advanced enough where we can use nanobots to generate power in the bloodstream through chemical reactions, heat or flow of the blood like katbug suggested earlier.
Im still waiting for electrically actuated artificial muscles. Once that is out of the way replacing limbs can become a lot easier and probably more power efficient.

We already have several ways to do that, including [URL="http://www.utdallas.edu/news/2012/11/15-20871_Wax-Filled-Nanotech-Yarn-Behaves-Like-Super-Strong_article-wide.html"]carbon nanotube/paraffin muscles[/URL].
I'm currently applying to be an Ammo Tech and to hopefully end up in EOD, not even passed selection yet and there's a robot lining up to take my job :v
How come we can't make something that uses the same amount of energy as our arms use
[QUOTE=damnatus;48086951]How come we can't make something that uses the same amount of energy as our arms use[/QUOTE]
Living beings are much more complex and some of that complexity is what makes our arms more efficient compared to current robotics, I guess.
I would love to see it being used on a person. You can build the best arm in the world but it's not much better than a hook if you can't control it properly.

Coming from an actual engineering working in developing new projects and automation the answer might just be "no". It's entirely possible that depending on the power draw of that arm that there's no way to power it right now while maintaining reasonable battery life and weight. Batteries have been holding back mobile technology to such an extreme that it's easily one of the biggest bottlenecks that exists today.
It's very cool to have such a detailed robot hand but honestly there's a very harsh reality in engineering: batteries have an energy density, and until someone improves them you can't help that. The answer of course isn't "this is impossible" it's just "this is impossible [i]restrained by the technology we have available now[/i]". If I had more information on the power consumption under typical use cases I could give a more in depth explanation of what kind of power unit you'd need, how much it would weigh, etc but as it is I can only guess aside from the fact that moving an object of x weight requires at least a certain amount of energy.
Projects get proposed all the time and shot down because somewhere along the way it comes to a point where someone says "well, we can't get a power system on there small enough to meet requirements with long enough battery to meet requirements" or "well, we can't get a camera on there that can capture with the resolution we need at the speed we need". Of course there's also the ultimate bugbear of project design: there's a part that meets all the requirements except for cost, it's too expensive for the product.

Makes me wonder, will there be a time when robot arms become so good, some people might wanna replace their perfectly fine arms with robot ones?
[QUOTE=Nikita;48110246][url=http://i.imgur.com/hi1pPWg.jpg]There is a solution but you might not like it.[/url][/QUOTE]
Yeah that's not really a solution so much as the problem itself but, you tried :v:
I guess an arm you need to plug in to use is better than no arm though. [sp]Plus you'd still need a (likely quite beefy) transformer and supply system to carry it around even if you needed to plug it in. Think laptop charger brick but for an industrial grade robot arm[/sp]

Then the trans-humanism debate starts. And that is one debate that will get 1000% ugly in record time.
