Video: MIT robofish set to snoop the deep seas
MIT has been at this robotic fish lark for a long, long time, and its latest iteration is a true testament to all the effort and energy put in. The first prototype, 1994's Robotuna, was four feet long and had 2,843 parts driven by six motors, whereas the new robofish is no longer than a foot, carries one motor and has exactly ten components, including the flexible polymer body. The hardy and relatively inexpensive drones can be used as substitutes for AUVs in tight spaces, inhospitable environments and the like, but their earliest adopters are likely to be supervillains in need of surveillance bots for their moats.

ROS: a common OS to streamline robotic engineering
The biannual International Joint Conference on Artificial Intelligence has this year shed light on a new effort to standardize robot instructions around a common platform, so that designers won't have to "reinvent the wheel over and over" with every project. Presently, robot design is undertaken in an ad hoc fashion, with both hardware and software being built from scratch, but teams at Stanford, MIT and the Technical University of Munich are hoping to change that with the Robot Operating System, or ROS. This new OS would have to compete with Microsoft's robotics offering, but the general enthusiasm for it at the conference suggests a bright future, with some brave souls even envisioning a robot app store somewhere down the line.

Found Footage: Control an unmanned aerial vehicle with an iPhone
What does a former US Navy F/A-18 Hornet pilot do with her time now that she heads MIT's Humans and Automation Lab? The short answer is "really cool stuff," and the long answer is even better. During her tenure as a pilot, Professor Cummings became frustrated with the Hornet's cockpit. "I spent whole time complaining - who was the moron who designed this thing?" she told Wired. At MIT, she and her students were inspired to consider a replacement for the huge controllers that US soldiers use to operate Raven unmanned aerial vehicles. Just six weeks and $5,000 later, they launched a working test flight of a small robotic crafted controlled by an iPhone. The app they've created relays GPS coordinates to the robot, which then travels from origin to destination on its own. Wired notes that the phone in the video is not jailbroken and the app in question was created like any other. It's very cool indeed. Now if they could only design something to get my kids to the bus stop on time.
Glass leaves sweat to generate electricity, get nervous in public situations
Researchers at the University of California, Berkeley, the University of Michigan and MIT have created glass "leaves" with networks of veiny channels filled with water. The smallest channels extend all the way to the edges of the leaf, where open ends allow water to evaporate, which draws water along the central stem of the leaf -- at a rate of about 1.5 centimeters per second. The glass leaves have been wired for electricity by adding metal plates to the walls of the central stems and connecting them to a circuit. Researchers then charge the plates and the water inside the stems creates two conducting layers separated by an insulating layer, which acts as a capacitor. The waterflow is then periodically interrupted with air bubbles, and every time a bubble passes through the plates a small electrical current is generated -- about 2 - 5 microvolts per bubble. The team thinks that on a large scale, artificial trees could be use to generate large amounts of energy entirely through evaporation.
MIT's Bokode tech calls out zebra stripes, QR codes for battle of barcode supremacy
Since barcodes are the sign of the devil (must be true, we read it on the interwebs) it's no surprise that everyone wants to replace 'em. QR codes have been quite popular, allowing people and companies to tag their stuff with colorful decals filled with bits and bytes, and of course RFID tags are still going strong, but a team of researchers at MIT has come up with something better: Bokode. It's effectively a tiny little retroreflective holograph that is just 3mm wide but, when a camera focused to infinity sweeps across it, the Bokodes become clear and appear much larger, captured in the video below. In this way they can contain "thousands of bits" of data and, interestingly, show positional information too, meaning the camera knows where in 3D space it is in relation to the tag. This, of course, has hundreds of potential applications ranging from grocery shopping to augmented reality, and should lead to new and exciting ways for scholars to interpret/misinterpret Revelations.

DIY wearable computer: now you don't have to go to MIT to look like a total nerd in public
We admit it: despite our general disregard for the benefits of higher education, we've always harbored deep jealousy for those incredibly intelligent jerks at MIT's Media Lab, traipsing around Massachusetts in their incredibly great wearable computers. Well, now that a MicroPCTalk forum member has built his very own wearable computer from a few spare parts lying around the house, we can finally put aside those futile dreams and get to work on our very own nerd-badge-of-honor. Mr. Fiveseven808 took a VAIO UX, Myvu Crystal wearable display, a bevy of Bluetooth peripherals and a iDEN i425 handset for connectivity. Sadly, his UX has since died, but there's more UMPC where that can, and those elitist MIT types can't keep us down forever.[Via SlashGear]
Video: MIT working on rapid recharging for electric vehicles
MIT's electric vehicle prototype may be a long way off from being completed, but if we let that stop us from discussing EVs, we might never talk about them. The headline ambition of the elEVen project is a full recharge within 10 minutes, which would eliminate somewhere between four and ten hours of waiting. Speedwise, the Electric Vehicle Team is aiming for a 100 mph top speed from a 250-horsepower / 187 kilowatt AC induction motor, and a not unheard of 200-mile cruising range. To achieve their rapid juicing aim, the students will strap 7,905 lithium iron-phosphate cell batteries from A123Systems to a gutted 2010 Mercury Milan Hybrid body. The batteries' low internal resistance is what makes things possible, but further hurdles, such as finding a sufficiently powerful energy source, would have to be overcome before any sort of widespread use may occur.

New Scientist and MIT track your trash for the good of the planet
On a long enough timeline, all gadgets, white goods, furniture and consumables end up in the trash bin, and the latest tech from MIT is designed to track their subsequent journey from your porch to the great beyond. Partnering with the New Scientist magazine, researchers are hoping that by mapping where garbage ends up, they can awaken that atrophied muscle of environmental awareness in us all. The project will attach SIM cards to particular items of trash, which will beep out their location information every 15 minutes. You might think this somewhat underwhelming -- given all the bells, whistles and bomb-proofing that garbage cans have been adorned with over the years -- but interest appears high enough to justify exhibitions of the project in New York and Seattle starting this September.
MIT researchers weave "flexible camera" out of fiber web
We've seen liquid camera lenses and cameras shaped like an eye, but a group of researchers from MIT's Department of Materials Science and Engineering are now taking things in yet another shape-shifting direction with a so-called "flexible camera" that uses a special fiber web instead of traditional lenses. Those fibers are each less than one millimeter in diameter, and are comprised of eight nested layers of light-detecting materials, which the researchers are able to form using an extrusion process like that used to make optical fiber for telecommunication applications. Once woven into a fabric, the researchers say the "camera" could be anything from a foldable telescope to a soldier's uniform that gives them greater situational awareness. Of course, they aren't saying when that might happen, although they have apparently already been able to use the fiber web to take "a rudimentary picture of a smiley face."
MIT scientists reverse engineer the ear for ultra-broadband, low power RF chip
Researchers at MIT have developed an ultra-broadband radio chip that's faster than any existing RF spectrum analyzer, while consuming 100 times less power. The RF Cochlea mimics the neural signal processing of the human cochlea, which uses fluid mechanics, piezoelectrics and neural signal processing to convert sound waves into electrical signals which travel to the brain. "The more I started to look at the ear," said Rahul Sarpeshkar, associate professor of electrical engineering and computer science, "the more I realized it's like a super radio with 3,500 parallel channels." The team has recently filed for a patent to incorporate the chip in a universal or software radio architecture that will process a broad spectrum of signals including cellular phone, wireless Internet, FM, and other signals. Ultimately, this tech could be used to build a universal radio that could receive a broad range of frequencies. Meet Professor Sarpeshkar in the video after the break.[Via Daily Tech]
Video: CTD's MID concept fits comfortably in freakishly large pockets
Sure, this isn't the sexiest MID render we've ever seen, but it does make for a fun little video. Cambridge Technology Development, known around MIT and environs for fluidic device design, CFD analysis, and a number of other things we know less than nothing about, have designed a collapsible, pocketable PC that they call the Dragonfly. This bad boy can take the form of a flip phone, a straight-up netbook, or it can lay flat, in "table mode," ideal for pen and touch input. Of course, this isn't a real device -- and there's no telling when or if it'll become available. But when it does, how about floating us a review unit? Check 'er out yourself after the break.
Ionic cooling system adapted for laptop use, scalded legs cautiously rejoice
To be totally candid, we can't even utter the word "ionic" without thinking of Sharper Image, but the concept here actually seems like one that just might benefit the public at large... or at least those of us forced to cook our upper legs on a daily basis. San Jose-based Tessera, in cooperation with the University of Washington, has adapted an ionic cooling system for use in everyday laptops. The magic elixir consists of two electrodes, one of which is used to ionize air molecules such as nitrogen, while the other acts as a receiver for those molecules. According to reports, this method can extract around 30 percent more heat from a lap burner than the traditional "fan and more fans" approach. Still, a major obstacle remains in terms of ensuring that the electrodes remain reliable throughout the life of a laptop, but if Tessera has its druthers, some form of the system will be commercialized next year.
New cuttlefish-inspired display tech can change color, eat your pet guppy
Cuttlefish are one of the most intelligent creatures in the sea, able to change their shape and color to escape predators -- but, they aren't smart enough to escape us, and they taste good, so they also go great with risotto. Scientists at MIT, however, decided not to eat their cuttlefish, instead using them to inspire the tech inside a new type of highly-efficient display. The screen is just one micron thick and contains a layer of poly-2 vinyl. Left alone it's clear but, when exposed to an electrical charge, its thickness and reflectivity can be controlled to create color. Just a few volts are required to form an image but, like e-ink, its design means backlighting is not an option. Viewing angles are also quite poor at this point, so this is one display tech that may take a long time to belly up at retail. Master of disguise video after the break.
MIT BiG: Levine talks life before BioShock
We're here at the MIT Business in Gaming conference this afternoon to watch Ken Levine – who holds the title trifecta of "co-founder, "president" and "Creative Director" at 2K Boston (née Irrational) – take the hotseat in a Q&A format (that, for some reason, is being billed as a "keynote"). No bother – given an opportunity to hear the BioShock developer discuss the current state of the industry (not to mention regaling us backstage with amusing yarns about Strauss Zelnick's protein-centric diet), we took our spot in the front row, laptops at the ready. After an introduction by one of the show's sponsors (get off the stage, bub!) the Q&A was handed over to MIT graduate student Dennis Fu, who peppered Levine with a series of questions inspired by the day's panel topics: digital distribution; in-game advertising; MMO business models; and serious games. Fu stepped right into the deep end, asking Levine "What can you tell us about BioShock 2?" As he's said before, he's keeping himself intentionally in the dark so that he can play it "as a fan." "We're sort of keeping ourselves at a distance," he explained.
CMU researchers control microbots with mini magnets
Pardon the alliteration, but we're excited about the proposition here. For years -- millenniums, even -- scientists have been trying to figure out how to manipulate minuscule devices with magnets, and at long last, we've got a breakthrough in the field. Metin Sitti, an associate professor of mechanical engineering at Carnegie Mellon University, is credited with creating a new control technique that could allow microscopic machines to "one day deliver drugs directly to a sickly cell or a tumor." Essentially, the diminutive bots glide across a glass surface covered with a grid of metal electrodes, and you're just a click away (it's the Read link, just so you know) from seeing a live demonstration on how they can be used to "anchor one or more microbots while allowing others to continue to move freely around the surface." Good times.
Video: robotic marimba player grooves autonomously with jazz pianist
We've seen an orchestra's worth of robotic musicians, but we've yet to see one that integrates this perfectly into a piece without any human intervention. Shimon -- a robotic marimba player created by Georgia Tech's Guy Hoffman (formerly of MIT), Gil Weinberg (the director of the Georgia Tech Center for Music Technology) and Roberto Aimi of Alium Labs -- recently made its stage debut by sensing the music from a piano and reacting accordingly in order to provide complementary percussion. Unlike many alternatives, there's absolutely no delay here. Instead, it analyzes the classification of chords, estimates the human's tempo and attempts to extract features from the human's melodic phrases and styles. What you're left with a robot musician that goes beyond call-and-response and actually meshes with the Earthling's playing throughout. The full performance is posted after the break, and make sure to leave a donation as you exit through the doors on the left.[Thanks, Guy!]%Gallery-51150%
Ken Levine keynoting first MIT 'Business in Gaming' conference
Focusing on riveting hot-button issues like "digital distribution, marketing, and in-game advertising," the MIT Sloan School of Management is kicking off its first ever "Business in Gaming " Conference (BiG) with BioShock magnate Ken Levine as inaugural keynote speaker. We'll be there, Big Daddy statues and permanent markers in tow, and when we're not ogling KennyL we'll likely check out the panel featuring ex-Boston Red Soxer Curt Schilling of 38 Studios speaking about MMO business models. Hey, maybe he'll talk about that game his company's been making for three years! Code-named Copernicus? No? You don't remember that one? Yeah, neither do we.
Wearable blood pressure monitor: portable and fashionable
We've seen some wild ideas when it comes to blood pressure -- including, yes, underpants -- but this newest device, a small monitor attached to the hand, which can be worn 24 hours a day for continuous monitoring, strikes us as having the potential for extreme usefulness. The monitor works differently than regular old blood pressure cuff, using a method called pulse wave velocity, which measures the pulse at two points along an artery. Built by a team of engineers at MIT, this prototype could boast a lot of advantages over monitors, including its portability, its ability to see long-term patterns of rises and falls in pressure, and of course -- you wouldn't have to be at the doctor's office to use it -- which is bound to take a little stress out of the equation. The device is moving toward commercial production and Harry Asada, leader of the MIT team, sees the possibility for monitoring conditions such as sleep apnea in the future as well.
Graphene chip could hit 1,000GHz, make your Core i7 feel totally inadequate
8GHz (with the help of liquid nitrogen) not quick enough? Leave it to the folks at MIT to make sure your zaniest desires are well taken care of. As research forges ahead on graphene, carbon nanotubes and buckyballs (remember those?), gurus at the university have discovered a breakthrough that could eventually lead to microchips that make existing silicon-based CPUs weep. In fact, the research could lead to practical systems in the 500 to 1,000 gigahertz range. The magic all ties back to advancements on a graphene chip known as a frequency multiplier, and while the nitty-gritty of all this is far too complicated for the layperson to grasp, all you really need to know is this: finally, you can rest assured that you'll one day own a chip capable of handling Duke Nukem Forever.[Via InformationWeek]
MIT dreams of fully autonomous greenhouse, will definitely make it happen
You know what's hard to find these days? Consistency and reliability -- in anything, really. But we've learned that when MIT touches something, it not only gets done, but it gets done right. Thus, we're absolutely elated to hear that a few of its students have dreamed up a fully autonomous greenhouse, utilizing real plants, sensors and gardening robots to ensure the greenest, most healthy crop possible. In fairness, we've already seen oodles of robotic plant tending apparatuses, but this is just something special. Thus far, gurus have used "re-imagined versions of iRobot's Roomba" in order to tell what a plant needs and then respond accordingly, and apparently, things have been going quite well early on.
