Carnegie Mellon's robotic snake stars in a glamour video


We've been pretty into Carnegie Mellon's modular snake robots for a while now, and seeing as it's a relatively sleepy Sunday we thought we'd share this latest video of snakebots just basically crawling all over the place and getting crazy. Bots like these have been getting some serious military attention lately, so watching these guys wriggle into any damn spot they please is at once awesome and terrifying. Or maybe it's just the music. Video after the break.

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.

Carnegie Mellon morphs 'pop-up buttons' onto multi-touch display


While attempts to add feedback to touchscreen displays via vibration and audible tones are laudable, these attempts are nothing by comparison to the tactile euphoria felt at the press of a well-designed button. Still, many of us are willing to sacrifice tactility in order to maximize display sizes on our pocketable or portable devices. Now researchers at Carnegie Mellon have developed touch-sensitive displays with physical buttons that "pop-out" from the surface. CM's prototypes pump air through geometric-shaped holes to create concave or convex "buttons" on a screen covered with a semi-transparent latex -- IR sensors and cameras detect finger placement while a projector cast images (like numbers and graphics) onto the display. It can even sense press-force by monitoring changes in air pressure. Sure it all sounds overly cumbersome until you see the technology demonstrated. For that you can travel to Pittsburgh to count the rivers or just hit the read link below for the video.

Sensor-laden footballs / gloves could run referees right out of work


Dr. Priya Narasimhan, a professor at Carnegie Mellon University, doesn't intend to put a single NFL referee out of work, but there's no doubt that the technology she's tinkering with could indeed have that effect. The prof and her students are developing sensor-laden footballs and gloves, both of which could eventually tell in real-time whether a ball bounced off the ground before being caught or whether a player actually had possession of a ball whilst being piled upon after a fumble. Currently, she's had zero luck persuading a college or professional team to help her experiment further, and we can sort of see why. We mean, it's nice to get every call right in theory, but what fun would sport be without the all-important "Ref, you suck!" chant?

Caterpillar and CMU team up to create world's largest robotic monster truck


We're always hearing about some fantastical, nigh-mythical creation that Carnegie Mellon University is in the midst of cobbling together from spare parts, crazy ideas, and pure, simple genius, so maybe we shouldn't be frothing over the new robotic truck they've partnered up with Caterpillar to create, but this one promises to be the "world's largest." Adapting software CMU used in the DARPA Urban Challenge, the team hopes to end up with fully automated, 700-ton trucks capable of moving up to 42 miles per hour which will be used for mining. The trucks would theoretically reduce costs, increase productivity, and save lives. The Frankenstein-ed vehicles will boast GPS, laser range finders to identify large obstacles, video equipment, and a "robotic driver." The scientists somewhat predictably foresee some (as of now) rather far-fetched consumer applications in cars and trucks over the "next five to ten years," but we're taking that with a few salt grains for now. The trucks aren't ready quite yet but we hear their arrival is imminent, and and we can only imagine that somewhere in the world, Grave Digger is crying to himself.

Update: We've changed the title to reflect the accurate arrangement, which is a teaming up of CMU and Caterpillar, not DARPA. Thanks to the commenter who pointed that out.

Carnegie Mellon brings adhesive arms to the burgeoning pillbot scene


We've seen plenty of pill bots in our day -- most of the dumb little swallowable cameras -- but Carnegie Mellon University isn't messing around with this stuff. The nerds over there have built a remote controlled pillbot with small, adhesive arms that allow it to grip onto internal surfaces. That is to say, your internal surfaces. The pill can view damaged areas, deliver drugs and might eventually be outfitted with a small laser for cauterizing internal wounds. Yes, we just said lasers.

Waalbot, the wall-climbing, gecko-footed robot

Waalbot
Robots do all sorts of things, but climbing walls seems to be a goal engineers can't live without. Meet the Waalbot which is fitted with gecko-like micro fiber feet that can stick to vertical and ceiling surfaces. In addition, the legs are wheeled with three feet that can rotate and cruise over surface curvature and even grab onto other walls at right angles. Unlike other wall-climbing robots, this one is small and light, and given its diminutive size, capacity varies depending on the surface type and size of feet. Using a PIC microcontroller and wireless controls along with batteries, Waalbot is designed to be completely autonomous and untethered.

HandTalk glove speaks your hand gestures... we can see where this is headed


Oooh, now we get it. HandTalk converts hand gestures like sign language into spoken words. Well, don't we feel silly. The device was developed by a group of nerds at Carnegie Mellon, and can track finger and hand gestures with a vocabulary of 32 words in its existing v0.1 model. The signals are transmitted from the glove to a phone over Bluetooth, where the words are converted with text to speech software. Not bad for a bunch of off-the-shelf components, but they could've scored double the nerd points by repurposing a Power Glove for this -- gotta think big picture, people.

Pittsburgh museum plans "largest national" robotics exhibition


Heads-up Pittsburgh residents and robot lovers across the universe: an all new exhibition is coming to the Steel City next year, and it's got high, high hopes. The $3.4 million display, which is slated to be "permanent," will be housed in the Carnegie Science Center and go by the not-at-all-puzzling title of "roboworld." The installation is expected to house an "array of mechanized devices," and given that it's being billed as the "largest and most comprehensive nationwide on robotics," we'd say it's got a lot to live up to. Of course, we'll be utterly shocked if it even compares to the now-closed Robot Museum in Nagoya, Japan, but we suppose we'll have to see for ourselves when the doors fling open in Spring 2009.

Shape-shifting magnetic bots take a page out of the Dharma playbook


Research is still in the early stages, but the concept renders are straight out of science fiction. Some friendly folks at Carnegie Mellon University are working towards electromagnetic microscopic bots that cling together and can assume virtually any shape. Down the line that means rapid prototyping, the promise of "claytronics," and the mysterious deaths of plane crash victims, but current examples of the tech are anything but slick. The primary uniting element is that the bots being developed have no moving parts, instead using magnetic forces to pull themselves around in relation to each other. Peep the video after the break for some samples.

Carnegie Mellon's "Crusher" military bot getting $14 million upgrade

Carnegie Mellon's so-called "Crusher" unmanned military vehicle already had quite a bit going for it in its previous incarnation, but it now looks to set to expand its robotized arsenal even further, courtesy of a $14.4 million grant from the Army. According to the university's National Robotics Engineering Center, the updated bot will make use of the "latest suspension, vehicle frame, and hybrid-electric drive technologies to improve upon its predecessor's performance" while also promising to, somewhat ominously, "push the envelope for autonomous and semi-autonomous operation." That the NREC says, should allow the bot to begin working alongside troops in five or ten years, with it initially confined to convoy roles before it puts its autonomous skills to use in "tactical" missions.

DIY'er gets busy with automatic projector calibration


While you may not think a 4+ minute clip involving a monotone narrator, flashes of light and lots of sensors could hold your attention (okay, so maybe that came off a bit more riveting than we'd hoped), we'd bet the one posted after the jump could. The video demonstrates a fairly svelte automatic projector calibration system, which relies on very little hardware (and time) to work its magic. Essentially, the low-cost method utilizes rear-mounted optical fibers wired into light sensors, which can channel gray-coded binary patterns through a USB connection. From there, a PC determines precisely how the projection should be outputted for the target surface to be completely filled with an undistorted image. We know, it's tough to wrap your head around, but all the enlightenment you could ever want (on this subject, anyway) is just a mouse click away. [Warning: PDF read link]

DARPA's Urban Challenge set to roll Saturday with 11 robotic cars


Oh man, can you taste it? That oily titanium tang is the smack of robotic cars set for release Saturday in the DARPA Urban Challenge. The final event pits 11 vehicles in competition for a $2 million first, $1M second, and $500k third place prizes. The 60-mile course at the former George Air Force Base in Victorville CA must be successfully navigated in less than 6-hours while avoiding about 50 carbon-based drivers. Can Stanford repeat their 2005 Grand Challenge victory with "Junior" or will Carnegie Mellon's "Boss" (pictured) bust out a BFG-9000 in swift retribution? Tune in Saturday to find out.

Carnegie Mellon shows off "Scarab" lunar rover

It looks like the moon could soon become a relatively crowded place if even half of all these robots and rovers we keep hearing about actually get off the ground, the latest of which comes to us from Carnegie Mellon University. Dubbed the "Scarab," this four-wheeled bot is equipped with a Canadian-made drill capable of obtaining meter-long geological core samples, which its creators hope could turn up evidence of hydrogen, water or other recoverable resources. While it's appearance would suggest otherwise, the Scarab apparently won't be tearing up the lunar surface if and when it gets there, with it boasting a top speed of just four inches per second. On the upside, it will apparently be able to maneuver over rocky surfaces, and it can anchor itself to the ground to stay in place while drilling. While that would be enough for most folks to call it a day, it seems that project leader William "Red" Whittaker won't be resting on his lunar laurels, as he's also announced that he'll be assembling a team to compete for the Google Lunar X-Prize, which promises $20 million to anyone that can land a privately funded robot on the moon by 2012.

2007 Robot Hall of Fame Inductees: now 75% more real


The Robot Hall of Fame has always struck as a little odd, what with their inclusion of fictional bots, but it looks like the class of 2007 might the one that turns the tide. For the first time in the four-year history of the Hall, the jury of 25 roboticists selected more real bots than fictional -- LEGO Mindstorms (pictured), the NAVLAB 5, the Raibert Hopper, and Mr. Data made the cut this year, making the final score three real to one, uh, television. While you know how we love Mindstorms, and we're glad to see Data finally make it, the two lesser-known inductees also seem pretty trick to us: NAVLAB 5, a robotic Oldsmobile Silhouette, was honored for driving itself from Pittsburgh to San Diego way back in 1995, while the Raibert Hopper one-legged hopper made it for containing the basic tech DNA that underlies all those two- and four- (and more) legged bots we've got running around these days. Congrats to the honorees, and here's hoping the real bots keep it up.
