Cornell’s Ranger robot walks 40.5 miles on a single charge, doesn’t even break a sweat (video)


A few years ago, engineers at Cornell were rejoicing when their Ranger robot set an unofficial world record by walking for 5.6 miles without stopping. Since then, the 22-pound bot has only built up its endurance, to the point where it can now chug along for a full 40.5 miles without a single battery recharge, or an ounce of human assistance. The Ranger pulled off the feat last week, when it completed nearly 308 laps around the university’s Barton Hall running track, over the course of more than 30 hours. Engineers say that their bot’s stamina has a lot to do with its energy efficiency. The Ranger runs on about 16 watts and uses them more sparingly than most of its mechanized brethren. It also saves juice by swinging its legs more liberally than most bipedal walkers, essentially allowing its limbs to fall freely before re-stabilizing itself. The robot’s next challenge, apparently, will be to incorporate automatic steering into its gait, since walking in circles can get understandably dull, after a while. Gallop past the break for the full PR and a video of the Ranger’s latest achievement.

Touch pad prototype works without movement, makes fingertips feel like they’re sliding (video)

This comes from the same touchy-feely Kajimoto lab in Japan that brought us the tactile kiss transmission device and we totally see where they’re going with it: maximum sensation, minimum effort. You only have to exert the gentlest of pressures on this prototype touch pad and it zaps your fingertip with little electrical signals, mimicking the feeling of sliding your finger over a surface. We imagine it’s a bit like the little red pointing stick in the middle of a Lenovo ThinkPad keyboard, for example, but with the addition of “position-dependent data input” to create the illusion that your finger is actually touching different areas of the screen. For now though, if you don’t mind stretching a finger to your old-stylee mouse or trackpad, then check out the video after the break.

Microsoft’s Rock and Rails touchscreen lets you massage your photos with both hands

If you ever get tired of poking away at your smartphone’s screen like a doorbell, you’re not alone. The forward-looking folks over at Microsoft Research have been working away at a new touchscreen system designed pick up on more natural, whole-hand movements, effectively allowing users to break free from the finger-based paradigm that governs most tactile devices. Developed in coordination with engineers at Microsoft Surface, the company’s Rock and Rails interface can detect three basic hand gestures: a balled fist, which holds items on the screen, an extended hand that can align objects (see the cell marked “d,” on the right) and a curved paw, around which users can pivot images (see cell b). This taxonomy opens up new ways for users to crop, re-size or generally play around with their UI elements, though it remains unclear whether the display will trickle down to the consumer level anytime soon. For now, it appears to operate exclusively on the Surface, but more details should surface when the system’s developers release a paper on their project, later this year. Hit the source links to see a video of the thing in action.

Ultra-thin handheld microscope could sniff out skin cancer, forged documents

It may not look like it, but that sleek black thing pictured above is actually a microscope. Designed by engineers at Germany’s Fraunhofer Institute for Applied Optics and Precision Engineering IOF, this little guy boasts a 5.3mm optical length, rendering it slim enough to fit in the palm of your hand, yet powerful enough to deliver images at a scanner-like resolution of five micrometers, over a wide surface area. Fraunhofer’s researchers achieved this balance by essentially tossing out the manual on traditional microscope design. Whereas most devices slowly scan areas and construct images on a piecemeal basis, this handheld uses several small imaging channels and a collection of tiny lenses to record equal sized fragments of a given surface. Unlike conventional scanner microscopes, all of these 300 x 300 square micrometer imaging channels are captured at the same time. With a single swipe, then, users can record 36 x 24 square mm shots of matchbox-sized objects, without even worrying about blurring the images with their shaky hands. The prototype is still two years away from going into production, but once it does, engineers say it could help doctors scan patients for skin cancer more easily, while also allowing bureaucrats to quickly confirm the authenticity of official documents. We can only imagine what it could do for Pac-Man. Full PR after the break.

Flexible PaperPhone wants to get bent out of shape (video)

We love our smartphones (in part) because they’re flexible, in the sense that they are mighty multitasking machines. Researchers from Queen’s University in Ontario Canada, however, want flexible phones in a literal sense — less five-tool player, and more master contortionist. Using a ductile e-ink display and elastic electronic underpinnings, they created a device called the PaperPhone that literally bends to its user’s will. Curling the corners of the device isn’t just for show, either, as folding the phone is how users navigate menus and make calls. We aren’t completely sold on the idea of a bend-based UI, but we’re definitely digging the lithe and lightweight phone form factor. Video of the new flexi-phone is after the break.

Update: A second video showing the same 3.7-inch display in a wearable computer project dubbed, “snaplet,” has been added after the break.

NVIDIA losing ground to AMD and Intel in GPU market share

NVIDIA may be kicking all kinds of tail on the mobile front with its ubiquitous Tegra 2 chipset, but back on its home turf of laptop and desktop graphics, things aren’t looking so hot. The latest figures from Jon Peddie Research show that the GPU giant has lost 2.5 percentage points of its market share and now accounts for exactly a fifth of graphics chips sold on x86 devices. That’s a hefty drop from last year’s 28.4 percent slice, and looks to have been driven primarily by sales of cheaper integrated GPUs, such as those found inside Intel’s Clarkdale, Arrandale, and most recently, Sandy Bridge processors. AMD’s introduction of Fusion APUs that combine general and graphics processing into one has also boosted its fortunes, resulting in 13.3 percent growth in sales relative to the previous quarter and a 15.4 percent increase year-on-year. Of course, the real profits are to be made in the discrete graphics card market, where NVIDIA remains highly competitive, but looking at figures like these shows quite clearly why NVIDIA is working on an ARM CPU for the desktop — its long-term survival depends on it.

Tactile kiss transmission device finally makes it okay to smooch your computer (video)

They say the vast majority of communication is done physically rather than verbally, but in the realm of technological advances we seem to have rather neglected the transmission of physical contact. Thankfully, there’s always Japan to provide us with off-the-wall innovations, this latest one being a kiss transmission device that will record, relay, and — if you wish it — replay your finest tongue gymnastics. It’s the height of simplicity at the moment, with a plastic implement taking input from one person’s mouth and conveying it to a second box, intended to be gobbled up by the recipient of this techno-affection, who may respond in kind or just sit back and enjoy the thrill of it. The researchers sagely point out that there’s more to be done, as the sense of taste, manner of breathing, and moistness of the tongue are all important aspects of a kiss that have yet to be recreated. Once they do get their kiss transmitter to v2.0, however, they envision a pretty neat market for it in reselling kiss replays performed by celebrities. For now, you can see a celeb-free video demo after the break.

Nanocones make solar cells more efficient, sinister looking

Going green is de rigeur, so the sun is becoming a much-preferred source of power. However, solar cells’ inefficient harvesting of heliacal energies is a major reason they haven’t usurped the power of petroleum. Good thing the big brains at Oak Ridge National Laboratory are looking to change that with nanocone-based solar technology. The teeny-tiny cones are made of zinc oxide and create “an intrinsic electric field distribution” to improve electrical charge transport within solar cells. We aren’t sure what that means, but we do know the prickly-looking design provides a 3.2 percent light-to-power conversion efficiency that’s a substantial improvement over the meager 1.8 percent offered by today’s flat photovoltaics made of similar materials. That’s 80 percent more efficient, and 100 percent more awesome.

SETI suspends search for alien life, E.T. weeps in the silent dark of space

Our progress toward intergalactic fellowship has suffered another blow, as SETI suspended operations of its Allen Telescope Array. Funded by Microsoft co-founder Paul Allen, the array is a collection of radio dishes that scan the skies for signs of life; now it’ll be in “hibernation” mode until 2013, when the institute’s new round of funding begins. SETI hopes to raise $5 million to bring the Array back online before then, while it continues to use other telescopes around the world, including the Hubble Space Telescope. The budget woes are especially bitter given the number of recently identified alien planets – NASA’s Kepler mission found 1,235. If any of them are broadcasting the next Wow! signal, let’s hope it doesn’t fall on deaf earthling ears.

Researchers build synthetic synapse circuit, prosthetic brains still decades away

Building a franken-brain has long been a holy grail of sorts for scientists, but now a team of engineering researchers have made what they claim to be a significant breakthrough towards that goal. Alice Parker and Chongwu Zhou of USC used carbon nanotubes to create synthetic synapse circuits that mimic neurons, the basic building blocks of the brain. This could be invaluable to AI research, though the team still hasn’t tackled the problem of scope — our brains are home to 100 billion neurons, each of which has 10,000 synapses. Moreover, these nanotubes are critically lacking in plasticity — they can’t form new connections, produce new neurons, or adapt with age. All told, the scientists say, we’re decades away from having fake brains — or even sections of it — but if the technology advances as they hope it will, people might one day be able to recover from devastating brain injuries and drive cars smart enough to avert deadly accidents.
