EPFL's printing technique hides one image behind the other
Remember those holographic cards that give off different colors when you tilt them a certain way? Well, in the video below the fold, the École Polytechnique Fédérale de Lausanne demos metallic cards similar to those, except they're much, much cooler. The institute has developed a printing technique that prints two images together, and to see the second picture, you merely need to rotate the photo. One card in the video, for instance, looked like it was the image of a gray umbrella, but when rotated 90 degrees, it showed a rainbow-colored one instead.
Mind-controlled robot gives the disabled a taste of home
Brain-controlled robot limbs have already helped the disabled gain some mobility, but full-fledged robots have proven elusive: how do you use thoughts to steer a free-roaming machine? Swiss researchers think they have the answer. They've developed a mind-controlled telepresence robot that lets those with motor disabilities travel when it would otherwise be impractical. It's ultimately a laptop on a pedestal, but it uses clever semi-autonomous software to take the hard work out of controlling where the robot goes. You only have to don an EEG-based cap and imagine moving your hands or feet -- the robot plots a path based on your commands, and avoids obstacles all on its own.
Brain simulation breakthrough reveals clues about sleep, memory
The Blue Brain Project is a vast effort by 82 scientists worldwide to digitally recreate the human brain. While still far from that goal, the team revealed a breakthrough that has already provided insight into sleep, memory and neurological disorders. They created a simulation of a third of a cubic millimeter of a rat's brain. While that might not sound like much, it involves 30,000 neurons and 37 million synapses. In addition, the simulated level of biological accuracy is far beyond anything so far. It allowed them to reproduce known brain activities -- such as how neurons respond to touch -- and has already yielded discoveries about the brain that were impossible to get biologically.
ICYMI: Bro-saving weight bench, 4-gram robot and more

A 4-gram robot can move two different ways: As an inchworm, or by flicking itself in the air with flippers that get a charge from a mild electric current. And an art project made of a 3D-printed top uses eye tracking sensors and software to let the wearer know when he or she is being stared at by responding with movement.
4-gram 'Tribot' shows off heat-activated high jumping
At the École Polytechnique Fédérale de Lausanne (EPFL), a laboratory that specializes in origami robots has created one that was inspired by the inchworm. The tiny 4-gram machine called "Tribot" can crawl, jump seven times its height and then resume crawling without any resting period in between. Since Jamie Paik's team at the Reconfigurable Robotics Laboratory couldn't use typical bulky motors to create a light and foldable machine, they had to use titanium and nickel "shape memory alloy" to build actuators and springs for it. Tribot crawls by heating those memory alloy parts with an electric current -- the heat makes its limbs "remember" or pop back to their original shape after expanding. In the video below, you can watch the researchers discuss both Tribot and the other origami robot they're developing, a four-limbed "Crawler."
Researchers develop multifaceted insect eyes for UAVs
A team of researchers from the Laboratory of Intelligent Systems at the Swiss Federal Institute of Technology (EPFL) have developed a tiny new set of electronic eyes for drones that are based on the multifaceted peepers of insects. These eyes are built specifically for the next generation of very small surveillance UAVs -- like that origami quadcopter EPFL developed earlier this year -- and operate very differently than the conventional cameras currently employed. Insect eyes aren't capable of generating a high spatial resolution (that is, the number of pixels you can pack into a single image) so they instead rely on quickly reacting to changes in how light reflects or objects appear as the insect moves. The new camera works the same way.
ICYMI: 3D-printed art, a Pac-Man satellite and more

Switzerland's EPFL space agency realized its old cubesats were cluttering up space so it came up with a hungry hippo of a satellite that should start gobbling up its smaller kin by 2018. And an architect hacked a 3D printer with LEDs and is creating beautiful paintings with light.
Tiny palm-top UAV folds itself up like an origami quadcopter
Tiny quadcopters that fit in the palm of your hand have been around for a few years now, but very few of those drones can also fit in your pocket; what with their easily snapped rotor spars. However, a pair of researchers from the Swiss Federal Institute of Technology recently unveiled a clever and unique mini-UAV design that keeps the rotors safely tucked away until it's ready to fly.
Behold the first photo of light in both wave and particle forms
You've likely read in a textbook before that light behaves both as a particle and a wave at the same time. Scientists had previously seen it behave one way or another, but it's only now that someone finally found a way to photograph light as both in a single picture since Einstein proposed its dual nature in the early 1900's. In order to photograph light, a team of scientists from the Ecole Polytechnique Federale de Lausanne (EPFL) used a novel technique and an electron microscope so powerful, there are only two in the world.
Flexible spinal cord implants will let paralyzed people walk
Doctors dream of helping the paralzyed walk through implants that stimulate their spinal cords, but current technology makes that impossible; these stiff, unnatural gadgets usually end up damaging or inflaming nervous tissue over time. Swiss researchers may have just solved this problem once and for all, though. Their bendy e-Dura implant combines flexible electrodes (made of platinum and silicon microbeads), cracked gold electronic tracks and fluidic microchannels to deliver both electrical impulses and chemicals while mimicking the spine's movements and avoiding friction. Paralyzed rats in lab tests could both walk again after a few weeks and keep wearing their implants after two months.
Motion-detecting nanosensors could help find life on other planets
Much as we'd love to discover grey aliens with warp drive technology, any extraterrestrial life we're lucky enough to find will likely be pretty basic. But the chemical detection methods used by space probes like Curiosity or Philae are hit-and-miss -- they can't actually tell if something is alive or not. Scientists in France have developed a new nanosensor that may help: a simple cantilever with a laser motion sensor that can accept about 500 bacteria. As long as they're alive, the cells will cause minute vibrations on the cantilever, which are captured by the lasers as a sign of life. After scientists kill the cells, the signals stop.
Researchers have created an oscillator that could silence the mechanical watch
You're running late to a meeting, glaring at your wrist in disbelief that it's fifteen minutes past the hour. Are you really that late? Lifting the watch to your ear you hear the all-too familiar tick of its internal mechanisms. Yes, it works -- and you are indeed late. This scenario could soon be a thing of the past, mostly because the mechanical watches of tomorrow may not tick at all. Researchers at École Polytechnique Fédérale de Lausanne have created a new, silent oscillator that could potentially be used to make watches with fewer mechanical parts.
Scientists build a robot arm that catches objects in the blink of an eye
Humans are good at catching fast-moving objects -- just ask any baseball fan. Robots typically lag behind, however, which is why the École Polytechnique Fédérale de Lausanne (EPFL) has developed a robot arm with the reaction time needed to catch just about anything. After learning the basic concepts by imitating human behavior, the machine uses its cameras to predict the path of a flying object and grab it in less than five hundredths of a second -- roughly as fast as it takes you to blink. It can even adapt to objects whose center of gravity is likely to shift around, such as a half-full drink bottle.
Swiss scientists create catbot: a robot that runs like a cat (video)
Someone call MIT's researchers and tell them their terrifying cheetah robot has a long-lost teensy sibling in Switzerland. Developed in the laboratories of the École Polytechnique Fédérale de Lausanne, the "cheetah-cub robot" is a four-legged metallic critter modeled after a house cat. The scientists focused on designing legs that can move like our feline friends', paying particular attention to their stability while moving on uneven surfaces. While it has a long way to go before it becomes a graceful daredevil, it's a fast little bugger that can run seven times its body length in one second. The researchers hope their creation gives rise to more robots for exploration and search-and-rescue missions in the future -- a far more noble goal than some cat-owners' dream to have their pets' pictures land on the front page of Reddit.
EPFL mixes graphene and molybdenite to make very efficient, flexible flash memory
We've seen graphene chips, and we've seen molybdenite chips. What would happen if we combined the two? If EPFL's experimental flash memory is any clue, we might get one of the better blends since chocolate met peanut butter. The chip uses graphene's high conductivity for the memory itself, as well as for electrodes, but stuffs molybdenite in between to rapidly switch electrical states (such as what you'd see in write commands) while using little power. The hybrid is theoretically both faster and more power-efficient than conventional silicon designs, but that's just the start: the extra-thin nature of either material is better-suited to flexible electronics on top of shrinking the chip footprint. If there's anything at this stage that would sour EPFL's dreams of a storage utopia, it's time. There's no immediate mention of commercialization plans for the mutant memory, which could leave us stuck on silicon for awhile.
Swiss bionic hand offers true sensations through the nervous system
Those wearing bionic hands and similar prostheses often suffer a frustrating disconnect when they can touch an object but can't feel it, even if they're using direct neural control. The École Polytechnique Fédérale de Lausanne and allies in Project TIME have developed a hand that could clear that psychological hurdle. The design implants electrodes directly in key nerves that not only allow motor input, but deliver real sensory feedback from the artificial appendage -- including needle pokes, much to the test subject's chagrin. An early trial (seen above) kept the enhanced hand separate from the wearer and was limited to two sensations at once, but an upcoming trial will graft the hand on to a tester's arm for a month, with sensations coming from across much of the simulated hand. EPFL hopes to have a fully workable unit ready to test in two years' time, which likely can't come soon enough for amputees wanting more authentic physical contact.
Drone-maker Parrot invests $7.5 million in two EPFL spin-offs, sets sights beyond toys
Switzerland's EPFL has managed to catch our attention with its various UAV-related activities, and it looks like it's also been the radar of Parrot, maker of the AR.Drones. EPFL announced today that the French company is investing 7.4 million Swiss Francs (or about $7.5 million) in two companies that have been spun out of the institution: senseFly and Pix4D. As you may recall, those two have collaborated in the past, with senseFly providing the camera-equipped UAVs necessary for Pix4D's 3D mapping software. Broken down, the investment works out to 2.4 million Francs put into Pix4D and five million invested in senseFly, the latter of which is enough for Parrot to claim a majority stake company. As for the future, senseFly's CEO says that the deal will give Parrot "access to the expertise and the technology for specialized drones," while Pix4D's CEO says that the investment "reinforces our position as a leader in software for professional drones" and opens up new business opportunities. It also makes it clear, if it wasn't already, that Parrot is getting pretty serious about drones. You can find the official announcement after the break, along with a video from EPFL explaining the deal.
AirBurr micro air vehicle can self-right, take off again (video)
EPFL's been tweaking its eerily floating AirBurr since 2009, and its latest iteration adds four carbon-fiber legs, hopefully ensuring you'll never have to chase after and recover it after a crash. When the seemingly clunky frame crashes, it's that same intentional design that will ensure gravity rolls the device towards its side, allowing the legs to extend out and let the MAV relaunch itself -- even off gravel. Hit up the source link to see how the design has evolved over the years, but before that, see it crash and burn return right after the break.
EPFL's CleanSpace One: clearing up cosmic clutter (video)
Where are Lone Starr and Barf when you need'em? Would that those two (fictional) interstellar handymen-for-hire were real, space agencies like Switzerland's own, could outsource the tricky and costly intergalactic housekeeping that's fast becoming a high-priority. Instead, the famously neutral country is investing 10 million Swiss francs (about $10.8 million USD) into the production of a new breed of satellites dedicated to the collection and destruction of orbital debris. The project, dubbed CleanSpace One, will tackle one of two Swiss-borne, celestial objects -- the SwissCube or Tiasat -- for its initial mission, slated for some time within the next three to five years. While our very own NASA has proposed the use of a laser to redirect these non-operational and potentially hazardous craft, the brains over at EPFL (Swiss Federal Institute for Technology) are in the process of developing a micro-electric propulsion system, in addition to a retrieval mechanism for the unit. So, what'll happen to both this outer space Rosie and her doomed cargo? Well, rather unfortunately, it's a suicide mission, as both are destined for burn-up on re-entry. Yes, it's a rather grim end to an otherwise noble voyage, but such is the price of our scientific spring cleaning.
