Kids with disabilities can teach this robot how to play 'Angry Birds'
As a way to help children dealing with cognitive and motor-skill disabilities, researchers from Georgia Tech have developed a rehabilitation tool that pairs a robot and an Android tablet. To demonstrate this system in action, the research team used Angry Birds to let kids teach the humanoid how to play Rovio's popular game. Essentially, the robot is smart enough to learn by simply watching each move the child makes while flinging those birds toward the iconic green pigs. "The robot is able to learn by watching because it knows how interaction with a tablet app is supposed to work," writes project leader Ayanna Howard, a professor at Georgia Tech. "It recognizes that a person touched here and ended there, then deciphers the information that is important and relevant to its progress."
CNN wants to prove that drones are safe for news reporting
Stunning video footage like that from a recent tornado in Arkansas (see below) shows the potential for drones to radically change journalism. However, it's illegal to operate them in the US, especially near a disaster or accident scene -- which has prompted a new research project from CNN and the Georgia Institute of Technology. The aim is to figure out which type of equipment, personnel and safety measures would be needed to safely operate news-gathering drones in US airspace. While such UAVs would no doubt give media outlets like CNN improved coverage, they'd often end up in close proximity to crowds, emergency personnel and even rescue aircraft. That means US regulators might be reluctant to approve them for reporting -- even though they've already authorized lower-risk activities like pipeline inspection. CNN's group hopes to show the FAA that it can be made safe for journalism, likely so that it won't be frozen out when new drone regulations are finally announced.

High-tech gloves can teach you Braille even if you're distracted
It looks like a team of Georgia Tech researchers is in the business of making wondrous, high-tech gloves -- their most recent one, for instance, can teach you Braille even if you're doing something else. Similar to the piano-teaching glove they designed years ago, this new pair has vibrating motors on each knuckle that buzz in different patterns to correspond with preset Braille phrases. To test how well the gloves work, they asked volunteers during an experiment to play a game for 30 minutes while the motors buzz along with audio cues. When the subjects typed the phrases after half an hour, the researchers found their answers to be mostly accurate, with some even getting perfect scores.
It's not just you: Terms of Service agreements really are confusing, study finds
You know that page with a check box you haphazardly agree to on the way to signing up for various online services? The one with the hundreds (or thousands) of words of legal mumbo jumbo? Yeah, we do the same thing -- it's okay. It's because those pages, the Terms of Service, are boring, lengthy, and probably meaningless. Right? Right?! Not necessarily. And a new study from Georgia Tech of the "top 30 social and fan creation sites" (from Facebook to Daily Motion) backs that up. Well, first things first: yes, Terms of Service agreements really are difficult to read. Of the 30 sites surveyed, an average reading level of college sophomore was required for comprehension of the TOS. To put it another way, around 60 percent of working age adults in the US (25 - 64) don't understand what they're agreeing to. "It is likely that users may not know what rights they are granting," the study says.
Researchers teach smartphones to recognize your activity, lock out everyone else
Swipe patterns, passwords and fingerprint scanners are useful for keeping that mobile device locked down from the outside, but what happens once that code is cracked? Well, cybersecurity researchers at Georgia Tech have developed LatentGesture that continuously monitors gadgets for intruders based on taps and swipes. If the system detects any use patterns that vary from the observed user profiles, it locks the device down. "The system learns a person's 'touch signature,' then constantly compares it to how the current user is interacting with the device," said College of Computing assistant professor Polo Chau.
This robotic prosthesis gives drummers a third arm
For many drummers, losing part of an arm could represent a career-ending tragedy. Not Jason Barnes, however. Georgia Tech professor Gil Weinberg has built a robotic prosthesis that not only restores much of Barnes' musical prowess, but effectively gives him a third arm. The wearable offers direct control of one drumstick using bicep muscles; a second, automated drumstick monitors Barnes' timing and plays in sync at a customizable pace, creating a sound that ordinary humans can't match. As you might imagine, the robotic arm has advantages for metal and other musical styles where complex drumming is essential. However, Weinberg also sees uses for the technology in other fields -- astronauts and surgeons could perform complicated tasks in harmony with robots, for example. You can catch a brief demo of Barnes' augmented skills in the video below, and you can check it out in person at Kennesaw State University's Robotic Musicianship Demonstration on March 22nd.

Georgia Tech's Tongue Drive wheelchair proves quicker than traditional breath controls
Georgia Tech researchers believed that tongue-controlled devices could help the disabled, and now they have solid proof. A new study shows that the school's wearable Tongue Drive System lets the paralyzed control wheelchairs three times faster than they would using an ordinary breath-based approach. The speediness is due to TDS' intuitive design, Georgia Tech says -- wearers use a magnetic piercing in their tongue as a joystick, which is both faster and more logical than puffing into a straw. It's subtler, too, as wearers don't block their faces with as much equipment. Trials have so far been limited to hospitals and labs, but the findings pave the way for real-world tests. Eventually, Georgia Tech hopes for widespread use that improves tetraplegics' mobility -- and gives them more control over their lives.
Nanowire sensor converts pressure into light, may lead to super-sensitive touch devices (updated)
Outside of pen input, pressure sensors don't get much love these days. However, Georgia Tech has just built an extremely accurate sensor that could give pressure-based devices their due. When a user pushes down on the new invention, its grid of zinc-oxide nanowires emits light that's captured by fiber optics underneath at a very sensitive 6,300DPI. The combination of high resolution with light-speed responsiveness could lead to touch surfaces that capture far more detail than we're used to. While computing interfaces are clearly prime candidates for the technology, Georgia Tech also sees potential uses in pressure-based fingerprint readers and even devices that simulate touch with skin-like behavior. We've reached out to the school for more information regarding its long-term plans, but it already anticipates improving the sensors with more efficient manufacturing techniques. Take a closer look at the sensor after the break. Update: We've since had a chance to follow up, and we're told that commercialization is likely five to seven years ahead.
Apple says iOS 7 will patch exploit that lets rogue chargers install malware
Recently, Georgia Tech researchers discovered an unusual way to attack iOS: a third-party charger with a hidden computer can install malware when an iOS device is plugged in and unlocked. That won't be an issue for much longer, however, as Apple has confirmed that iOS 7 beta 4 and future releases contain a fix. While the company hasn't said what that solution is, Georgia Tech's Billy Lau says that the new OS can tell when it's plugged into a computer instead of a charger -- there shouldn't be any rude surprises. The dependence on an iOS 7-based fix could leave many users vulnerable until the fall, although the hardware-specific nature of the exploit means it's unlikely to be a major concern.
AT&T to open Foundries in Atlanta and Dallas that focus on home automation, device-to-device tech
AT&T launched its first Foundries primarily as mobile app incubators, but the carrier is switching focus tonight: it just unveiled plans to open more hardware-oriented Foundries in Atlanta and Dallas. Most Atlanta-based projects will expand AT&T's Digital Life home automation service, with connected cars and U-verse also receiving a boost. The Dallas Foundry complements an existing presence in the city, but will pay attention to the internet of things and other forms of machine-to-machine chatter. In either circumstance, collaboration will be key. The Atlanta location will sit right next to Georgia Tech, while hardware makers at the new Dallas office can get software help at the original Foundry one floor down. The two new locations won't open until a few months from now, but the Foundry program's healthy track record suggests that patience will be a virtue for interested developers.
Artificial sense of touch gets smarter, lets robots really feel
The verdict's still out on whether or not androids dream of electric sheep. But their ability to feel? Well, that's about to approach levels of human sensitivity. We're of course talking about the sense of touch, not emotions. And thanks to work out of Georgia Tech, tactile sensitivity for robotics, more secure e-signatures and general human-machine interaction is about to get a great 'ol boost. Through the use of thousands of piezotronic transistors (i.e., grouped vertical zinc oxide nanowires) known as "taxels," a three-person team led by Prof. Zhong Lin Wang has devised a way to translate motion into electronic signals. In other words, you're looking at a future in which robotic hands interpret the nuances of a surface or gripped object akin to a human fingertip and artificial skin senses touch similar to the way tiny hairs on an arm do. What's more, the tech has use outside of robotics and can even be levereged for more secure e-signature verification based on speed and pressure of a user's handwriting. And the best part? These sensors can be manufactured on transparent and flexible substrates like the one pictured above, which allows for various real-world applications -- just use your imagination. Pretty soon, even robots will have the pleasure of enjoying the touch... the feel of cotton and maybe even hum that jingle to themselves, too.
Recyclable organic solar cells: a clean fuel future made possible by trees
You don't have to know Shel Silverstein to know that trees are exceptionally giving. They're responsible for our homes, paper, air, furniture and, now, energy -- the "clean" kind, that is. Researchers from the Georgia Institute of Technology and Purdue University have jointly devised a patent-pending method to build organic solar cells using plant-derived substrates. Known as cellulose nanocrystal substrates (or CNC), these solar cells benefit from being truly disposable, eliminating the waste that results from the use of alternative materials like petroleum or glass. The CNC-made cells are not only transparent enough to allow light to pass into an embedded semiconductor, but they also dissolve when submerged into water, thus earning the esteemed recyclable distinction. Although this is undoubtedly a breakthrough for clean energy tech, it's by no means a near-future reality. Apparently, current cells can only yield a 2.7-percent conversion efficiency rate, which falls far below the 10-percent threshold met by rival fabrication methods (i.e., petroleum and glass). So, there's still significant work to be done before the team can improve production and achieve parity with those less "recyclable" options. Until that time, consider this a comforting reassurance that a clean fuel era is well within reach.
SuperPop Project develops game for children with motor skills impairments, aided by Microsoft's Kinect (video)
The tools available to therapists tasked with helping children with motor skills impairments improve their range of motion are definitely helpful. But the Human-Automation Systems Lab at Georgia Tech is looking to make said tools even better (specifically for those with cerebral palsy) with the SuperPop Project. With the use of a Kinect and display -- two items that may already be in many homes -- what children will see as a game is actually helping to build upper-arm motor function. The setup is fully customizable on the back end, which allows the therapist to tailor sessions to each patient and to his or her individual progress. During the course of play, the software tracks the coordinates of the user's joints, collecting loads of data for analyzing progression / regression and the like during the course of the rehabilitation. Head on past the break for a quick look at the setup in action.
Access4Kids input device allows disabled children to control touch-centric tablets (video)
The innovation world at large has been crafting ways for handicapped individuals to interact with computers for years on end, but the issue of tablets has created another predicament entirely. How do you enable someone to masterfully control a touch-centric device, when the mere act of touching is a challenge? Ayanna Howard, professor of electrical and computer engineering at Georgia Tech, and graduate student Hae Won Park have created Access4Kids, which is described as a "wireless input device that uses a sensor system to translate physical movements into fine-motor gestures to control a tablet." In essence, it enables individuals with limited mobility to pinch and swipe, and the group has had success thus far with providing greater accessibility to flagship programs like Facebook and YouTube. Moreover, custom-built apps for therapy and science education are cropping up, with the existing prototype utilizing a trio of force-sensitive resistors that measure pressure and convert it into a signal that instructs the tablet. A child can wear the device around the forearm or place it on the arm of a wheelchair and hit the sensors or swipe across the sensors with his or her fist, providing an entirely new level of interaction for those with cerebral palsy, traumatic brain injury, spina bifida and muscular dystrophy. The goal? Once it's honed, to get it out of the lab and made "into a commercial product." Head on past the break for a video look.
Deceptive robots mimic squirrels and birds for potential military use
The military has come up with a multitude of ways to utilize robotics, from bomb disposal and recon bots to Avatar-like surrogates. But a robot that takes its cue from squirrels and African birds to deceive its enemies is decidedly novel territory. Researchers from Georgia Tech, who are also working on a MacGyver bot with AI smarts, are making inroads into developing just such a robotic trickster. The Office of Naval Research is funding the project, which is led by Professor Ronald Arkin. He discovered that squirrels often deceive competing squirrels by visiting fake stash locations while their real acorn collection lies elsewhere, and have developed a robotic model that utilizes the same strategy. The programmed deceptive behavior was successful, as demonstrated in the video after the break. Another lesson from nature is from the African babbler, a species of bird that flocks and crowds around a predator without actually attacking it, with the assumption that it'll back away from the harassing mob. Based on their simulations, the team concluded that deception of this sort is often the right move when pushed against the wall, especially in military operations. "Being honest about the robot's abilities risks capture or destruction," said Arkin. However, he recognizes there is a real ethical quandary when it comes to deceptive robot behavior -- do we really want robots that can lie to us? It's a question that conjures up memories of Battlestar Galactica and brings chills down our spine. Here's hoping we can restrain the robotic deception to the good of mankind.
Swarm robots perform classical 'scores' inside Georgia Tech's GritsLab (video)
The folks at the Georgia Robotics and InTelligent Systems (Grits) Lab at Georgia Tech have been hard at work for some time now researching swarm robots. A portion of said work deals with tasks that require a group of hi-tech gadgets to individually reach a location and a specific time -- much like the mobile landing platform that we saw last year. The group is given a "score" and must determine how many of the Khepera robots are needed to meet the goal, assigning specific roles and determining the shortest route to hitting their targets. One particular demo that we saw involved the swarm bots playing a projected piano of sorts to perform a short snippet of Beethoven's "Fur Elise" -- internal cameras, special "hats" and cameras mounted around the room lend a hand in carrying out the assigned duties. Musical performance is just one of the projects underway in the GritsLab. A real-world scenario involves the use of swarm robots for convoy cover. Using Parrot AR.Drones alongside the diminutive machines that we saw in action, researchers are looking at ways in which UAVs can be deployed to investigate and eliminate threats to convoys on the ground. This allows for the convoy to take an alternate route if needed while remaining under the watch of at least one UAV. For a look at the aforementioned classically scored action, jump down past the break to take a gander.
Researchers harness static electricity from your twitchiness to charge batteries
If you're the fidgety type, new research from Georga Tech may one day turn your nervous energy into a fully charged cellphone. The scientists, who previously borrowed piezoelectric power from walking, created static electricity generated from movement between plastic and metal, similar to the way a balloon can be electrified by rubbing it on your hair. The charging area was greatly increased by patterning the surfaces on a nanoscale level, allowing this "tribolectric effect" to be multiplied and converting up to 15 percent of the mechanical energy into electricity (so far). About 50 common materials could be paired to create the material, and a 2 x 2-inch patch could conceivably be worn as an armband and used to charge up a cellphone battery. So far the tech works fine in the lab, but it remains to be seen if real world vibrations can generate enough energy to make it practical. While you're waiting, though, feel free to stock up on coffee.
Georgia Tech receives $900,000 grant from Office of Naval Research to develop 'MacGyver' robot
Robots come in many flavors. There's the subservient kind, the virtual representative, the odd one with an artistic bent, and even robo-cattle. But, typically, they all hit the same roadblock: they can only do what they are programmed to do. Of course, there are those that posses some AI smarts, too, but Georgia Tech wants to take this to the next level, and build a 'bot that can interact with its environment on the fly. The project hopes to give machines deployed in disaster situations the ability to find objects in their environment for use as tools, such as placing a chair to reach something high, or building bridges from debris. The idea builds on previous work where robots learned to moved objects out of their way, and developing an algorithm that allows them to identify items, and asses its usefulness as a tool. This would be backed up by some programming, to give the droids a basic understanding of rigid body mechanics, and how to construct motion plans. The Office of Navy Research's interest comes from potential future applications, working side-by-side with military personnel out on missions, which along with iRobot 110, forms the early foundations for the cyber army of our childhood imaginations.
Insert Coin: Shimi iPhone robot is ready to dance its way out of the lab, into your heart
As soon as we saw Georgia Tech's Shimi, we wanted to how many sleepless nights we'd have to spend waiting for one to proudly display on our desk. And really that's the whole idea behind the iPhone-enabled dancing robot: bringing some sophisticated robotic concepts to the consumer, in an adorable little package. Now the wall-eyed "first musically intelligent robotic speaker dock" has hit Kickstarter, ready to dance its way into reality. When finished, Shimi will feature six-watt speakers on either side of its face and five motors that allow it to dance and turn its head to the best position for optimal listening. Shimi does the latter via facial recognition software, tracking you around the room. The 'bot can also respond to verbal requests like "look at me," and "play Justin Bieber" (their suggestion, not ours). In the future, its creators will be offering up apps for gaming, telepresence and the like, as well as an SDK for developers. The Kickstarter page has a decidedly lofty $100,000 goal to hit by October 10th. Pledge $129 or more, and you get a Shimi of your very own. Check out a video of the 'bot and its creators after the break.
Georgia Tech develops self-charging battery that marches to the owner's beat
One of the last times we saw the concept of a self-recharging battery, it was part of a high-minded Nokia patent whose ideas still haven't seen the light of day. Researchers at Georgia Tech are more inclined to put theory into practice. Starting from a regular lithium-ion coin battery, the team has replaced the usual divider between electrodes with a polyvinylidene difluoride film whose piezoelectric nature produces a charging action inside that gap through just a little pressure, with no outside voltage required to make the magic happen. The developers have even thumbed their noses at skeptics by very literally walking the walk -- slipping the test battery under a shoe sole gives it a proper dose of energy with every footstep. At this stage, the challenge mostly involves ramping up the maximum power through upgrades such as more squeezable piezoelectrics. Georgia Tech hasn't progressed so far as to have production plans in mind; it's nonetheless close enough that we could see future forms of wearable computing that rarely need an electrical pick-me-up.
