Those of you who’ve seen The Wolverine , remember that crazy self-adjusting gurney thing that Master Yashida was lying on? That might not be as far off a piece of technology as you’d think. A team of researchers at MIT Media Lab’s Tangible Media Group have created this mind-blowing Dynamic Shape Display with a similar vertical-pixel-grid set-up: Called inFORM , the system provides a fascinating way for one party to physically manipulate objects at the other’s location. It has to be seen in action to be believed: (more…)

MIT’s Dynamic Shape Display is Like a Sandbox in California that You Can Manipulate from New York
Anyone who’s seen James Cameron’s Aliens cannot forget the images of 1.) Ripley in a cargo-loader exoskeleton, and 2.) Vasquez prowling the corridors with that body-mounted machine gun on the swing arm. That was back in 1986; now it’s 2013, and not only have these designs actually come to pass, but they’ve been combined. As we previously reported , Lockheed Martin licensed a company called Ekso Bionics’ technology to develop the HULC , or Human Universal Load Carrier. It’s got the power-assist legs and the body-supported gun mount: While Ekso Bionics is targeting the consumer market, enabling paraplegics to walk again, Lockheed has initially gone military. However, they’re reportedly creating a version of the HULC called the Mantis, for industrial applications. As Bloomberg News reports , The machines may follow a classic arc from Pentagon research project to fixture on an assembly line, similar to the development of lasers, said Paul Saffo, managing director of foresight at investment advisory firm Discern in San Francisco. “The medical devices get the most attention, the military funds it and the first mass application is industrial,” Saffo said in a telephone interview. [Mantis is aimed at] any industry in which workers must hold heavy equipment that can cause fatigue and back injuries…. Mantis has a mechanical extension for a wearer’s arm and absorbs the strain from hefting a grinder or sander, [Lockheed business development manager Keith] Maxwell said. Tests found productivity gains of more than 30 percent, he said, and wearers showed their Macarena footwork to demonstrate the suits’ flexibility. “It turns workers away from being a weightlifter and into a craftsman,” Maxwell said. I’m all for Construction Worker Exoskeletons—as long as the power tools are not integrated, but remain separate objects that you pick up. Because once they start replacing the user’s hands with built-in angle grinders and magazine-fed nail guns, we’re going to have a problem. Last year, I watched a construction worker fight a cabdriver in front of my building; the hack didn’t stand a chance. The last thing I want to see is an angry frame carpenter tramping off the jobsite in one of these things, ready to settle someone’s hash with his Forstner-bit fingers and chopsaw hands. (more…) 
Illinois-based Superior Joining Technologies is “a Woman-Owned Business,” as they proudly point out; for several years they’ve also been the owners of an incredibly bad-ass machine called the Trulaser Cell 7040 , a 5000-watt beast manufactured by Germany’s Trumpf. The Trulaser 7000 series are multi-axis laser cutting and laser welding machines that run off of CAD file input. What can these machines do with metal? A better question is what can’t they do. Observe their sheer majesty: By the bye, while I rate this video highly for the machine’s kick-assery, I still think the cat guy would’ve made this video awesome. (more…) 
It makes such little cents You probably know that the U.S. penny used to be made out of copper, which was once inexpensive. As the cost of copper began to rise, it would have cost more per penny than the penny’s own value, so the U.S. Mint switched over to a zinc alloy. But the price of zinc has been steadily rising since 2005. Which is why U.S. currency is in the absurd situation it is now: A one-cent piece costs about 2.4 cents to make. A penny is 97.5% zinc and 2.5% copper, and that zinc ain’t cheap. The nickel’s got it even worse. This five-cent coin costs 11.2 cents to manufacture. That’s because 75% of it is zinc and 25% is, well, nickel, another expensive metal. Which means that a nickel costs more to produce than every U.S. bill from a one-dollar bill (5.2 cents) all the way up to a C-note (7.7 cents). The money math starts to make a little more sense when we get to the smaller dime (92% copper, 8% nickel), which rings in at a production cost of 5.7 cents. The quarter, which has the same ingredients as the dime, is only a slighly better bargain at 11.1 cents. Clearly the U.S. Mint needs to start researching cheaper alloys or phasing out the penny and the nickel. It’s true that the math is a little more complicated than it would be for pure product manufacturing; for example, while you’d quickly go broke selling a product for $100 that cost $240 to make, currency is a little trickier. The government has an obligation to produce and circulate currency because it enables commerce, so it’s okay if they lose a little in manufacturing costs, as its citizens will theoretically make it back up by creating wealth. But if we don’t do that fuzzy math and look at it in terms of straight production, in 2012 alone the U.S. government lost $58 million dollars just by making pennies. (more…) 
Materials movement sucks, and it’s our job as designers, engineers or craftspersons to learn tricks to deal with it. You’ll put a slight arc in a plastic surface that’s supposed to be flat, so that after it comes out of the mold and cools the surface doesn’t get all wavy; a furniture builder in Arizona shipping a hardwood table to the Gulf states will use joinery that compensates for the humidity and attendant wood expansion; and similar allowances have to be made when joining steel and aluminum, as they expand at different rates when the temperature changes. On this latter front, Honda’s engineers have made a breakthrough that those who work with fabrics may find interesting: They’ve discovered that by creating a “3D Lock Seam”—essentially a flat-felled seam for you sewists—and using a special adhesive in place of the spot-welding they’d use with steel-on-steel, they can bond steel with aluminum in a way that negates the whole thermal deformation thing. Practically speaking, what this new process enables them to do is create door panels that are steel on the inside and aluminum on the outside. This cuts the weight of the door panels by some 17%, which ought to reduce fuel consumption. (Honda also mentions that “In addition, weight reduction at the outer side of the vehicle body enables [us] to concentrate the point of gravity toward the center of the vehicle, contributing to improved stability in vehicle maneuvering,” but that sounds like spin to us.) Unsurprisingly they’re mum on how they’ve pulled this off or what exactly the adhesive is, but they do mention that “these technologies do not require a dedicated process; as a result, existing production lines can accommodate these new technologies.” The language is kind of vague but it sounds like they’re saying they don’t require massive re-tooling, which is a manufacturing coup. Honda’s U.S. plants are the first to get this manufacturing upgrade, and we’ll be seeing the new doors as soon as next month, on the U.S.-built Acura RLX. (more…)
