Jacketed hamsters demonstrate movement-powered nanogenerators
Imagine this -- one day, with enough steroids, your pet hamster actually could power your home by just running on its wheel. Georgia Tech researchers have discovered ways to "convert even irregular biomechanical energy into electricity," and it's demonstrating the finding by showing off jacket-wearing rodents that are game to run. According to the institution's Zhong Lin Wang, the minuscule nanogenerators "can convert any mechanical disturbance into electrical energy," which theoretically means that power can be driven by simple, irregular mechanical motion such as the vibration of vocal cords, flapping of a flag or the tapping of fingers. As with most of these university discoveries, there's no telling how soon this stuff will be pushed out to the commercial realm, but at least they've found something to keep the rats busy during the off hours.

Researchers tout new 60GHz RF chip for high-speed wireless transfers
It's not the only group toying around in the 60GHz frequency range, but a team of researchers from Georgia Tech's Georgia Electronic Design Center seem to be a bit further along than most, and they say that their new 60GHz RF chip could pave the way into a whole host of new, speedier wireless devices. Apparently, the chip is the first 60GHz embedded chip designed for multi-gigabit wireless use, and the researchers have already pushed it to some pretty impressive lengths, reaching speeds of 15Gbps at a distance of 1 meter, 10Gbps at 2 meters, and 5Gbps at 5 meters, while also maintaining the lowest "energy per bit" to date. What's more, while it's been flying a bit under the radar, the industry group Ecma International has already announced a new standard for chips capable of sending RF signals in the 60GHz range, which is apparently expected to be published as an ISO standard later this year.[Via Electronista]
Digitally Assisted Billiards makes everyone a pool shark
There's cheating, and then there's out-thinking the room. Georgia Tech's own Justin Needham and Matthew Straub are clearly headed for great things, as their Digitally Assisted Billiards is reason enough to give these guys a degree in our eyes. Using an array of low-end kit -- just an eBox 2300 embedded computer, Logitech webcam, 4- x 3-foot mirror, a VGA projector, pool table and a few extenders -- the two were able to concoct a system for visually displaying the expected trajectory of all possible shots based on the location of the balls still on the slate. For a much better idea of what we're hinting at, check the demonstration video after the break.[Via Hack-A-Day]
Researchers create wirelessly-powered robot swarm
Wireless power has come a long way from Nikola Tesla's early ruminations on the matter, and it looks like some researchers from Duke and Georgia Tech are now taking the idea to its logical, robot-powering conclusion. While their setup (thankfully) isn't yet able to power robots beyond the confines of the Q L-C resonator-equipped table, it does appear to work remarkably well in that limited proof-of-concept, with five bots each equipped with a non-resonant pickup coil able to follow a path around the table, or simply sit still to recharge their batteries. They were even able to power an LED light with the system for good measure. Natually, they eventually hope to expand the system to power larger swarms of robots and do away with the need for batteries altogether. Yeah, that's a good idea. Head on past the break for a video.
Researchers rework tongue-based communication
It turns out that the tongue isn't tied to the spinal cord (had we paid better attention in Bio101, we'd have known that), which goes a long way towards keeping it unimpared in the event of spinal cord injury. A team at Georgia Tech is developing a tongue-based apparatus for disabled people that, which not as elegantly packaged as the GRAViTONUS device we've seen earlier, fashions a pointing device from a small tongue-mounted magnet and sensors near the cheeks. The team has promised interactivity way beyond what can be done with "sip and puff" input methods; think "mouth replaces mouse" and you've got the idea. Hopefully Mavis Beacon tongue-typing and the incorporation of haptic feedback won't be far behind.
Goodbye, virtual environments. Hello, real environments.
With all the talk about virtual environments (virtual world is, after all, something of a misnomer), what if you could use the real environment and bring the virtual to you? That's been the fundament of Augmented Reality for some time, and the core of many a spirited discussion -- the overlaying of information, images, representation onto what we perceive of the real world. Information about products, places, people, directions to destinations. What about games? What if you could layer a gamespace into your physical environment? Or a non-game virtual environment, like Second Life, for example? The Escapist's Howard Wen talks to Blain MacIntyre, Associate Professor at the Georgia Institute of Technology who has been one of several researchers there hacking on the Second Life viewer, adding Augmented Reality features to the software. Are you a part of the most widely-known collaborative virtual environment or keeping a close eye on it? Massively's Second Life coverage keeps you in the loop.
SnoMote robots could autonomously explore Antarctic
We've seen a couple robotic efforts to explore the Arctic and the Antarctic, but they've all been remotely-operated -- unlike the SnoMote, a new bot being developed at the Georgia Tech that can navigate itself around ice and snow. Packs of the mini-snowmobile-based SnoMotes can negotiate with each other and "bid" on locations to investigate, and navigate by classifying microscopic fissures in the icy terrain. The bots haven't made it to the Antarctic yet, but they're apparently handling simulations quite well, and the plan is for teams of 40 to 50 of the $10,000 machines to wander the ice collecting data points for climate change models. Sure sure -- and the next thing you know, the Antarctic is the flashpoint of the revolution. Good plan, guys.
Georgia Tech researchers developing tricorder-like medical scanner
We've already seen some attempts to create a tricorder-like device, but this latest crack it at by some researchers at Georgia Tech looks like it could well be the closest to the real thing to date -- if it ever turns into an actual device, that is. The big advance with this one, it seems, is the use of a new mosaic narrowband filter, which includes photosensitive pixel sensors that can observe different wavelengths and allow for multispectral imaging. According to the researchers, the filter could also be laminated with standard imaging sensors used in digital cameras, making an all-in-one handheld device possible. That would apparently let individuals use the device to detect everything from the severity of bruises to contamination in food, or even perform remote sensing in mining, to name but a few applications. The researchers still have quite a bit more work to do on it before any of that's possible, however, and they're now seeking collaborative or financial support to further develop the device.[Via Daily Tech]
Laser-guided EL-E robot offers point-and-grab operation, the future
While we're usually content to watch the slow, inevitable progress towards humanoid robots, the researchers behind this EL-E bot might very well be on to something. Instead of making a robot that acts like humans, they've built a robot that chases around the dot made by your laser pointer, and picks up whatever you point at with his crane. Not exactly on the path to replicants, but perhaps that's a good thing -- a bot that can pick up stuff you aim at and bring it to you is much more useful in the here and now. Plus EL-E yells out stuff like "Bob's your uncle" when he completes tasks, and if that isn't progress we don't know what is.
Pocketable gas sensor aims to better understand asthma
Sure, we've got fairly sophisticated methods of curbing asthma attacks, but a new pocketable device could hold the key to unlocking more about the relationship between "asthma symptoms and the air a sufferer breathes." Reportedly, this device could allow researchers to look back after an attack has occurred and see exactly what was happening environmentally beforehand. Gurus at the Georgia Tech Research Institute have already been able to help one individual out, as they discovered a "pollutant pathway" from the volunteer's basement into the living room that was allowing vehicle exhaust and gasoline fumes to infiltrate the house. From here, the creators are hoping to downsize the device even further and make it more sensitive, but we've no idea if the current iteration will ever be used commercially.[Via NewScientist]
Researchers craft new testing device to detect early Alzheimer's
We've heard that the "gold standard" pen and paper test seems to work fairly well at detecting the earliest stage of Alzheimer's disease, but gurus from Georgia Tech and Emory University have teamed up to develop a much quicker method for accomplishing the same. The ten-minute DETECT test utilizes a head-worn visor with a built-in LCD, headphones and a handheld controller, which the patient interacts with as he / she is put through a series of visual and auditory tests that "assess cognitive abilities relative to age," gauge reaction time and measure memory capabilities. Initial tests have purportedly shown it to have "similar accuracy" to the aforementioned pen and paper test (which takes around 90-minutes to administer), and while we've no idea when the device will be available for public use, its creators have already formed a firm (Zenda Technologies) to commercialize it. Finally, a legitimate use for head-mounted displays -- thought we'd never see the day.[Via Wired]
MEMS-based smart fuses could guarantee desired explosions
While we certainly hope the average (read: not GI) jane / joe isn't overly concerned about the rate at which homegrown explosions detonate as desired, we understand the Army's need to have more faith in their own munitions. Reportedly, a new "smart fuse" conjured up at Georgia Tech could soon prevent bombs from experiencing fuse failure by using "semiconductor fabrication equipment to make hundreds of ultra-high precision detonators on a wafer at the same time." In addition to cutting down on the use of toxic heavy metals and increasing the safety of weapon production, the intelligent MEMS fuse will supposedly "incorporate built-in arm and fail-safe mechanisms that virtually guarantee that munitions go off when they should, every time." Weapons that fire when needed -- now there's a concept. [Image courtesy of Rich's Incredible Pyro]
Georgia Tech researchers demonstrate blowable user interface
Although a team from Kent State already whipped up a method for turning one's PC on / off with a simple puff of air, two gurus at Georgia Tech have created a full-blown (ahem) breath-controlled user interface. The low-cost, localized blowable UI -- cleverly dubbed BLUI -- apparently utilizes a built-in microphone along with a C++ application that computes the blowing inputs. Once installed, users can puff on either side of the screen in order to scroll left / right, icons can be selected depending on the fierceness of the puff and games could integrate the technology in to add another level of interactivity. Notably, the duo behind the creation is already investigating how to avoid false positives (i.e. inputs from nature when outside on a blustery day), and while we're not sure how close this stuff is to becoming commercially available (if at all), you can take a look at a videoed demonstration just beyond the break.

Study finds Roomba owners heart their vacuums, accept flaws
While we greatly appreciate the research done by the fine folks over at Georgia Tech, we can't exactly say that we're shocked to hear that Roomba owners (in particular) actually care about their vacuums. In a study revolving around the intricacies in human-robot relationships, gurus found that "some Roomba owners became deeply attached to the robotic vacuums and that there was a measure of public readiness to accept additional robots in the house -- even flawed ones." Interestingly, the report goes on to state that consumers would be less likely to complain if troublesome / faulty household bots were "emotionally engaging," and considering that some folks were willing to "buy new rugs, pre-clean floors and purchase refrigerators with higher clearances" for their Roomba, we suppose we can't really argue with the findings. Now, robot manufacturers, don't you go ditching quality just 'cause we're pushovers, capiche?[Image courtesy of Halo5]
Standard microphones could detect buried landmines
Sure, there's already a myriad of methods for detecting and safely clearing out buried landmines, but the current options certainly aren't easy on the wallet. Thanks to a recent investigation by Georgia Tech, however, commercially available microphones could actually be used "as near-ground sensors for seismic detection of buried landmines," and if effective, could replace the rather pricey radar-based alternatives most commonly used. Recent trials using microphone data in an experimental model were said to "clearly locate buried inert landmines but exhibit more clutter than images formed with seismic displacement data collected using other techniques," but the excess noise may be worth the trouble if the cost savings prove significant.[Via NewScientistTech, image courtesy of BBC]
Georgia Tech researchers develop gesture-recognizing watch
This isn't the first time we've seen some gesture-based technology come out of Georgia Tech, but it looks like they've made some fairly significant improvements, now touting it not just as a game interface, but as a means to control all your various gadgets. Unlike that previous system, which simply relied on a cellphone camera to track movement, this new system makes use of five infrared sensors to pick up on your gestures, which then get interpreted and sent to the device you're trying to control via Bluetooth. No word when you'll actually be able to do that yourself, of course, although the researches don't seem to see any limits to the technology's potential, even touting it as a means for doctors to control medical devices during an operation.[Via SlashGear]
The sights and sounds of RoboCup 2007
While you've already gotten a taste of the prep work involved at RoboCup 2007, we know a more multimedia-packed perspective of the gala is more likely to quench your appetite for roboto-a-roboto action. From mechanical canines bending it like Beckham to Wiimote-controlled AIBOs, Atlanta is the place to be if you're looking for all things robotic. Best of all, the gurus inside have translated their circuitry and programming skills over to the camera, and a well-stocked Flickr pool and YouTube library are already beginning to form. So go on, give the links below a gander, and be sure to check back as the week unfolds to catch even more of the madness at this year's RoboCup.Read - Northern Bites BlogRead - RoboCup 2007 Flickr poolRead - RoboCup 2007 YouTube library
RoboCup 2007: let the games begin
While we weren't able to get a first-hand glimpse of the mayhem that is RoboCup this time around, a camera-wielding Georgia Tech graduate student was able to do the honors for us all, and snagged quite a bit of impressive footage from the expo. Many of the shots were snapped during yesterday's practice rounds as competitors prepped their gear for battle (which began yesterday), and we must say that the oh-so-athletic Junior Soccer League robots are worth the price of admission alone. Still, even if witnessing robotic contention in person isn't enough to drag you to Atlanta, be sure to click through to get a glimpse of homegrown robotic innovation at its finest.
Augmented reality relationship game plays with your emotions
If you couldn't quite make it to the last Wii marriage counseling session, there's still good news coming from Georgia Tech. Thanks to a group of engineering minds at the university, a new augmented reality game (dubbed AR Facade) is placing you in the center of a marital spat with nearly limitless options. The program apparently runs on a back-worn laptop and utilizes an oh-so-tacky head mountable display, and developers suggest that being placed in the midst of an "interactive drama" allows you to choose sides, attempt to mediate, and basically "define your own way to win" as you try to talk some sense into the flustered couple. Interestingly, there's even talk of bringing such games "onto mobile phones" and into the workplace, but it looks like they've got a bit of hardware trimming to do first.[Via The Raw Feed]
earPod creation could add auditory menus to iPod, DAPs
Rumblings about the layout and design of Apple's iPod scroll wheel in particular have been making the rounds for what seems like ages, but a new development from the Microsoft Research labs could nix the need to pull your DAP out and nearly collide with foreign objects whilst scrolling to a new tune. Aside from the glaring curiousness that stems from a Microsoft-derived project being dubbed earPod, the team has purportedly been working with scientists at the University of Toronto "on software that could make it possible to navigate the menus of gadgets that use circular touch pads with only audio cues." Essentially, touching the scroll wheel would provide audio clips to help you find your way through menus without ever seeing the screen, which would certainly prove useful on screenless DAPs. Currently, the system is quite limited in regard to the number of cues available, but here's to hoping that text-to-speech capabilities can become integrated as well so we can cycle through the thousands of artists and songs without even needing a display.
