The Effort To Create an 'Iron Man' Type Exoskeleton
Nerval's Lobster writes: Tony Stark, as played by Robert Downey, Jr., is the epitome of suave wit—but without his metal shell, he's just another engineer who's made good. The exoskeleton is a technology platform that, while young, is gaining traction in industrial, medical and military circles. For several years, the U.S. Special Operations Command has been working on a Tactical Assault Light Operator Suit, or "TALOS," that would provide "provide [infantry with] comprehensive ballistic protection and peerless tactical capability," in the words of Gen. Joseph Votel, SOCOM's commander. Meanwhile, several companies—including Raytheon, Ekso Bionics and US Bionics—are working on products that could help the disabled become more mobile, or allow warehouse and other workers to handle physical tasks with greater efficiency and safety. That means people who specialize in robotics, artificial intelligence, and other areas have an increasing opportunity to get involved. According to Homayoon Kazerooni, president of Berkeley-based US Bionics and a professor of mechanical engineering at UC Berkeley, control and software engineers are the leads in developing these next-generation products. Although he can't estimate the ultimate size of the market for these intelligent exoskeletons, Kazerooni describes the industry as "fast-growing, but infant," with "very diverse uses" for the suits. Just don't expect the aforementioned suits to allow you to fly or blow anything up anytime soon.
Much like the movie, it's all about the energy source, the mechanics are a solved problem already.
The mechanics of how to keep a man from being turned to jelly when the suit gets tossed into a nearby building by the Hulk have been solved?
Seriously, though, there will never be an exoskeleton as maneuverable and fast as the Iron Man suit, since there is no way to protect the occupant from mistakes that cause sudden deceleration. Even a fast turn could be deadly.
Given the unpredictability in a military or search and rescue situation a power source would be problematic. In an industrial situation a tethered power source might be more practical and allow the operator better precision in a more timely manner than remotely controlled.
