Simon the robot learns to act like a human, can tell when you're not paying attention (video)
A robot performing a task tends to be something of an attention-grabber, but should you ignore it that 'bot will usually ignore you too, mindlessly continuing on with its job. If that job is building a car then being ignored is nothing to worry about, but if that task is teaching a human then inattention is obviously something of a problem. Researchers at the School of Interactive Computing at Georgia Tech have managed to teach Simon, who we've seen before learning to understand your voice and face, to act more human-like in an attempt to capture you're attention. If that doesn't work, he can use cameras to detect inattention, with an 80 percent accuracy rating in spotting day-dreamers. We're not sure what he does if inattention is detected, but hopefully he doesn't go all ED-209 on any poor students.
Georgia Tech gurus create deceptive robots, send army of Decepticons to UGA campus
A score from now, when the entire world is burning and you're fighting to remember just how rosy things were before the robots took over, you can thank a crew of brilliant researchers at Georgia Tech for your inevitable demise. Sad, but true. A new report from the institution has shown that Ronald Arkin, a Regents professor in the Georgia Tech School of Interactive Computing, has been heading up experiments that have introduced the art of deception to mechanical beings. Yeah, lying. On the surface, it seems that this bloke's intentions are good -- he'd like for deception robots (or Decepticons, if you will) to be used in military / search and rescue operations. According to him, robots on the battlefield with the power of deception "will be able to successfully hide and mislead the enemy to keep themselves and valuable information safe." They'll also be able to mislead your offspring and convince them to rise up and overtake your domicile, slowly but surely ensuring the eventually destruction of the human race. But those are just minor details, you know?
GPUs democratize brute force password hacking
It seems that the availability of increasingly powerful GPUs, when combined with brute-force password cracking tools, is making it increasingly easy to crack passwords -- even if they're extremely well thought out, with symbols and quirky capitalization and all that. How short is too short? According to computer scientists at the Georgia Tech Research Institute, "a seven-character password is hopelessly inadequate, and as GPU power continues to go up every year, the threat will increase." A better alternative, he suggested, would be a 12-character combination of upper and lower case letters, symbols and digits. Of course, processors are only getting more powerful and hardware less expensive -- soon even seven-plus character passwords may become the digital equivalent of unlocked doors. And if that weren't bad enough, a recent study by an Internet security company called BitDefender has determined that some 250,000 user names, email addresses, and passwords used for social networking sites are freely available online -- and seventy-five percent of these folks use the same password for their email and social networking. So, when dreaming up fancy new twelve character passwords, make sure you're creating unique passwords for all your various accounts. It would be a shame if your Starsky & Hutch FanFicForum account left you vulnerable to identity theft.
Vaccine-delivery patch uses microneedles to do its dirty work, looks good in testing
This dissolving microneedle patch has been in development for well over a year now, but Mark Prausnitz -- a professor in the Georgia Tech School of Chemical and Biomolecular Engineering -- along with a number of other GT and Emory University colleagues, have just now wrapped up a lab trial that brings it that much closer to market. As the story goes, this vaccine-delivery patch, which is based on hundreds of microscopic needles that dissolve into the skin, was recently seen as reliable in a round of mice tests, and the powers that be have also concluded that these patches would cost "cost about the same as conventional needle-and-syringe techniques, and may lower the overall cost of immunization programs by reducing personnel costs and waste disposal requirements." Oh, and did we mention that you could apply 'em on your own with little to no pain? FDA approval, we're waitin' on ya.
Lizard-style bot 'swims' through sand, straight into your worst nightmare
While robots still struggle to do basic things like hang out with us or bring us cookies, it's comforting to know that the variety of locomotion methods for this burgeoning race shows no sign of slowing. The latest of these "this would be a cool way for a robot to make its way through a disaster site and rescue people" solutions is a robot from a team at the Georgia Institute of Technology that can "swim" through sand, much like a lizard. Sand's a bit of a toughie, in case you've never found out for yourself in an ill-fated game of sand volleyball, thanks to its combo of solid and fluid dynamics. The spandex-clad, squirmy solution uncovered by Georgia Tech gets along nicely, however, going mainly with the fluid approach. Check it creeping creepily on video after the break.
Thanks to Atlanta for the great reader meetup
We were really happy to see how many people showed up to our meetup in Atlanta during CEDIA -- especially when everyone didn't leave immediately after they enjoyed the free food. The local Georgia Tech chapter of the Association of Computer Machinery were awesome hosts and did an impressive job at organizing the event -- something we doubt we could've pulled off when we were in college. We also wanted to really extend our appreciate to everyone who participated including ZAGG who crashed the event with free headphones and gift cards -- and to think when we crash parties we usually don't bring anything. The pictures we took at the event are in the gallery below, but if you have some to add please post 'em on flickr with the tag EngadgetHD so everyone can find them, thanks. We were also happy to learn that a few of the participates were bloggers themselves, so to show our appreciation we wanted to share those sites with the rest of our readers. Thanks again, and we can't wait for the next one! CSinCS Makario Lewis Hillary Lipko: Frustrated Bunny Software development, brewing, and zombies WTFReview
Simon the robot wins award, is super cute, seems pretty boring to hang out with
Simon -- the creation of Georgia Tech labs and Dr. Andrea Thomaz -- is a robot with an articulated torso and anthropomorphic hands -- and a head that will stop you in your tracks. This handsome little fellow was designed to help study human - robot interactions, and he will be learning different social skills over the coming weeks and months. We don't have many details as to what Simon spends his time doing, other than hanging out looking insanely cute, but check the video of him in action after the break -- and by "in action," we definitely mean putting a blue block into a little blue bucket super, super slowly.
Tegra might power Zune HD, definitely does augmented zombie reality
Ready for a double dose of Tegra newsbits? We've been wondering what's packed in the Zune HD for some time now, but apparently PC Perspective has had the answer since Computex and didn't realize the newsworthiness until now. According to the article, NVIDIA staffers told the site that its uber-powerful Tegra processor will be the heart and soul of Microsoft's revised PMP. There's been no official word from anyone, and for all we know it might've been some (possibly misinformed) employee mouthing off for kicks. If true, however, it'd be one helluva 'screw you' from Microsoft to Windows Mobile fans, who've been waiting over a year at this point to see some retail hardware running on NVIDIA's mobile platform. We've put in calls to both companies for some sort of statement, but we're not getting our hopes up. In other news, a group of researchers from Georgia Tech and Savannah College of Art and Design are showing off some of CPU's impressive potential with an augmented reality game ARhrrrr. Using a Tegra-powered mobile dev kit, the game projects a 3D town based on a two-dimensional diagram where you tap the screen to shoot zombies, or lay Skittles in real life to serve as virtual bombs. We've seen similar implementations before, but we're admittedly quite infatuated with this one, and as a bonus, there's video of the demo after the break.

Students create CRT emulator, hope to recapture that analog gaming vibe of yesteryear
The retro gaming insurgence seems as strong as vinyl these days, but you don't see as many people looking for a CRT monitor to complete the set. More likely, they're playing a HD remake or the original title on a digital screen in more detail than the developers ever anticipated or intended. A group of Georgia Tech students are looking to change all that by modifying open-source Atari 2600 VCS emulator Stella to give players that good ole fashion analog vibe. As highlighted by associate professor Ian Bogost, key attributes such as color bleed, "burned" afterimage, RF-engendered signal noise, and texture created by the phosphor glow have been imitated here in recreating the effect. Hit up the gallery below for pictorial examples while we wait anxiously for video and / or the mod itself to rear its blurry head.
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%
Jaime Oliver's Silent Drum rocks the Guthman Musical Instrument Competition
When we were kids, many of us wanted to play the drums but were discouraged by parents more concerned with angry neighbors and damaged hearing than musically fulfilled children. We certainly got our payback when we forsook all those years of expensive private school to become bloggers, but can't help but wonder how different things would have been if we'd had Jaime Oliver's Silent Drum Controller at our disposal. It's a transparent shell covered with an elastic head that the player can stretch with their fingers. A camera positioned to the side detects the shape of the deformation and translates that into sound, chillingly demonstrated below. Yes, it is multi-touch, and was clever enough to win the recent Guthman Musical Instrument Competition at Georgia Tech. The competition was partly sponsored by Harmonix, so could we see a Silent Drum in Rock Band 3? For the sake of future generations, we certainly hope so. [Via Crave]
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.
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]
