Michael Gielniak is teaching Simon to move more like a human

As robots get smarter and more capable and make their way from manufacturing assembly lines to a much wider variety of applications, we will be interacting with them in more and more situations. Currently, robots tend to move with jerky, stop/start motions, which can make it difficult for humans, who are accustomed to the fluid and dynamic movements of other humans, to easily recognize what the robots are doing. In an attempt to create robots that can better interact with humans, researchers at the Georgia Institute of Technology are getting robots to move in a much more human-like way.  Read More

Genetically engineered remote controlled animals ... what the? Using inexpensive and widely available technology combined with the latest techniques in optogenetics, researchers at Georgia Tech have created exactly that. Optogenetics is a mix of optical and genetic techniques that has allowed scientists to gain control over brain circuits in laboratory animals. Mary Shelly would be proud – or totally freaked out. But don't expect remote controlled poodles or parrots in your nearest pet store by Christmas, this might be a few years off.  Read More

The robot Cody placed alongside the test subject's bed

While many movies and TV shows would have us believe that hospital sponge baths are only carried out by nurses at either end of the attractiveness spectrum, the reality is no doubt generally somewhere in between. In fact, I’m sure a lot of patients and even more nurses would prefer such tasks were handled by a robot. Researchers at the Georgia Institute of Technology seem to have reached the same conclusion and have developed a robot that can autonomously perform bed baths to keep bedridden patients clean.  Read More

This computer-generated graphic shows a model of the cruise-efficient, short take-off and ...

What's wrong with this picture? If you said the engines are upside down, you'd be wrong. The odd engine placement is part of a cruise-efficient, short take-off and landing (CESTOL) aircraft concept from the Georgia Tech Research Institute which also sees mechanical wing-flaps replaced by high-speed blasts of air to generate extra lift. It's hoped that the development of such craft will make more airports available to fixed-wing jet aircraft by enabling take off and landing at steep angles on short runways, as well as reducing engine noise.  Read More

The SpectroPen could help surgeons see the edges of tumors in human patients in real time ...

Statistics indicate that complete removal, or resection, of a tumor is the single most important predictor of patient survival for those with solid tumors. So, unsurprisingly, the first thing most patients want to know after surgery is whether the surgeon got everything. A new hand-held device called the SpectroPen could help surgeons provide a more definite and desirable answer by allowing them to see the edges of tumors in human patients in real time during surgery.  Read More

Sensors sprinkled throughout the home beam information at a set frequency. Wiring wrapped ...

Smart homes of the future will automatically adapt to their surroundings using an array of sensors to record everything from the building’s temperature and humidity to the light level and air quality. One hurdle impeding the development of such intelligent homes is the fact that existing technology is still power hungry and today’s wireless devices either transmit a signal only several feet, or consume so much energy they need frequent battery replacements. Researchers have now developed sensors that run on extremely low power thanks to using a home’s electrical wiring as a giant antenna to transmit information.  Read More

Robots can perform an ever-increasing number of human-like actions, but until recently, lying wasn’t one of them. Now, thanks to researchers at the Georgia Institute of Technology, they can. More accurately, the Deep South robots have been taught “deceptive behavior.” This might sound like the recipe for a Philip K. Dick-esque disaster, but it could have practical uses. Robots on the battlefield, for instance, could use deception to elude captors. In a search and rescue scenario, a robot might have to be deceptive to handle a panicking human. For now, however, the robots are using their new skill to play a mean game of hide-and-seek.  Read More

Scientists from the Georgia Institute of Technology have documented a major breakthrough in the production of nanocircuitry on graphene, a material that many envision as the successor of silicon for our electronics needs. Using thermochemical nanolithography (TCNL), the team found that the electrical properties of reduced graphene oxide (rGO) can be easily tuned to reliably produce nanoscale circuits in a single, quick step.  Read More

More than 1,000 tons (2.2 million pounds) of titanium devices are implanted in patients worldwide every year with joint replacements one of the more common procedures. Light, strong and totally biocompatible, titanium is one of the few materials that naturally match the requirements for implantation in the human body. Researchers have now developed an improved coating technique that could strengthen the connection between titanium joint-replacement implants with a patient’s own bone. The stronger connection – created by manipulating signals the body’s own cells use to encourage growth – could allow the implants to last longer.  Read More

Georgia Tech's David Roberts with one of the laser testing glass boards

Traditionally, when someone wished to measure the total power delivered by a laser beam, they had to use something called a ball calorimeter. As the laser heated the interior of the ball, temperature readings would be taken. Now, however, a system has been created that utilizes reusable glass boards. It can measure a laser's total energy along with the total power and power density anywhere inside the beam more than one hundred times per second. It should be a boon to developers of high-energy laser weapons, as it will reduce the time required for testing, and get the weapons in the field faster.  Read More
