Artificial sense of touch gets smarter, lets robots really feel

Artifical 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.

The Engadget Show 43: Music with John Vanderslice, Black Milk, Dan Deacon, Pandora, Sub Pop and more!

These days, music and technology are inexorably linked — from creation and recording, to distribution and discovery, it’s hard to imagine a song reaching our ears that hasn’t made its way through some electronic filter. Being the huge music nerds we are, we figured we’d use our April episode to explore the state of the music industry in 2013 and the roles technology has played in its successes and failings. This month, we start things off with a visit to Santa Cruz, where UCSC professor emeritus David Cope has spent decades developing classical music composing computer programs, work he began after one particularly bad bout with writer’s block. We also stop by Seattle’s Experience Music Project, where we speak to curator Jacob McMurray about the role technology has created in building a better music museum.

Next up, we’ve got a trio of interviews with artists who are using technology to very different ends in the creation and distribution of their music. John Vanderslice is the founder and proprietor of San Francisco’s Tiny Telephone, one of the last remaining analog-only recording studios in a world increasingly dominated by Pro Tools. He’s also a successful musician in his own right, who recently opted to eschew the traditional record label model for the release of his two new Kickstarter-backed albums. Hip-hop producer and emcee Black Milk, meanwhile, has taken to recording and producing recordings in his Dallas apartment. We discuss his crate digging, love of analog tools and the role of YouTube and Shazam in his production. And we meet up with indie electronic music Dan Deacon outside of LA’s Natural History Museum to talk about his live rig and innovative iPhone app.

What about radio stations, you ask? We pay a visit to Jersey City’s WFMU and Santa Monica’s KCRW, two of the most prominent freeform stations in a space dominated Clear Channels and internet and satellite radio, to discuss the importance of human curation and embracing the same technology that has spelled the end of so many of their peers. We’ve also got interviews with Seattle’s Sub Pop Records, music criticism site Pitchfork and California record store Amoeba, plus trips to music app developer Smule, internet radio pioneer Pandora and the legendary Moog factory. All that plus another installment of “John Roderick: Famous Prognosticator” and art by cartoonist Jim Rugg.

Oh, and we’d be remiss if we didn’t remind you that today is the last day to vote for us in the Webby Awards! In the meantime, check out the full show, after the break.

Hacked AP Twitter reports White House bombing, causes brief dip in Dow

Hacked AP report of White House bombing causes brief dip in stock market

You might have noticed that the AP’s Twitter account was hacked this afternoon and spread a report of a bombing at the White House. That yet another Twitter account was hacked isn’t the interesting part, it’s the immediate (if brief and shallow) plunge that the financial markets took. We don’t really need any further reminders of the power of social media, but it’s hard to ignore this particularly stark demonstration of the real-time effects. In this hyper-connected environment a breaking news tweet that was only live for a few minutes and, in retrospect, contained many glaring clues to its falsehood, caused the Dow Jones Industrial Average to drop to 14,567, from 14,697. Now, that only represents a roughly 1-percent drop, and it lasted only about as long as the tweet itself — the markets quickly bounced back and stabilized. But it is a firm reminder that virtual events can have significant real world consequences.

Watch live: Orbital Sciences’ Antares rocket to lift off on test flight (update: success!)

Watch live Orbital Sciences' Antares rocket to lift off on test flight update success!

SpaceX may be the only private outfit currently shepherding cargo to the International Space Station, but Orbital Sciences, which is the second party in NASA’s Commercial Orbital Transportation Services effort, is taking a step towards its own ISS resupply missions. Today, the firm’s Antares rocket will undergo its very first test flight, taking off from the space agency’s Wallops Flight Facility on Wallops Island, Virginia. Liftoff is slated for sometime between 5PM and 7PM, with an 80 percent chance of favorable weather, as opposed to the 45 percent odds and high-altitude winds that foiled its initial attempt yesterday. To watch Antares embark on its maiden voyage, hit the jump for a live video feed.

Update: Antares blasted off at a hair past 5PM and successfully separated from its mock payload. The live stream has wrapped up, but we’ll slot in a video of the launch as soon as we get ahold of one.

Update 2: NASA just posted its footage of the rocket taking off, and we’ve placed the video after the break for your viewing pleasure.

The After Math: Intel’s revenue billions, Android’s active millions and a few new Earth-like planets

Welcome to The After Math, where we attempt to summarize this week’s tech news through numbers, decimal places and percentages

The After Math Intel's revenue billions, finances from ten years ago and 15 million Android activations a day

As we scratch our head and puzzle over the almost-daily financial results for the last quarter, this week’s missive takes a slightly sentimental look at how two tech companies were faring a decade earlier. Is it unfair to compare the yesteryear Nokia to Google? Possibly. But it was the same year that a certain Engadget regular claimed a best-selling album — so it wasn’t all bad. Toshiba also unveiled a new pin-sharp Ultrabook to stand up to Apple’s Retina displays, and NASA continued the search for habitable planets.

DARPA flaunts HD heat vision camera small enough to carry into battle

DARPA thermal camera

Thermal imaging cameras are highly useful tools for military and law enforcement types, letting them see humans inside buildings or land a helicopter in the fog. High-definition models are too heavy for servicemen to tote, however, so DARPA and a private partner have built a 1,280 x 720 LIWR (long-wave infrared) imager with pixels a mere five microns in diameter. That’s smaller than infrared light’s wavelength, allowing for a slighter device without giving up any resolution or sensitivity while costing much less, to boot. Researchers say that three functional prototypes have performed as well as much larger models, allowing them to see through a simulated dust storm, among other tests. If DARPA ever lets such goodies fall into civvy hands, count us in — you can never have too much security.

NASA’s Kepler discovers three potentially habitable planets

NASA's Kepler discovers three potentially habitable planets

NASA’s Kepler telescope has discovered three “super-Earth-size” exoplanets that are close enough to their stars to make them possibly suitable for water. Two of the planets (Kepler-62e and Kepler-62f) orbit a K2 dwarf estimated to be around 7 billion years old. Measuring at two-thirds the size of our sun, this cosmic lantern is orbited by a total of five planets, three of which are too close to be habitable for life. Kepler-69c, the biggest of this newly discovered trio is estimated to be 70 percent larger than Earth and takes 242 days to revolve around its sun-like star Kepler-69. While there’s great excitement surrounding these new findings, this isn’t the first time we’ve spotted a potentially habitable planet. A little over a year ago Kepler discovered Kepler-22b, an exoplanet about 600 light-years away from Earth believed to be covered in liquid. Like their predecessor, NASA has yet to determine if these newfound planets actually have water or a rocky composition. Until then, Ridley Scott might want to hold off on naming them as locations for his sequel to Prometheus.

Electron showers could create the nano-spacesuit of the future

Electron showers could create the nanospacesuit of the future

Historically, whenever man or beast’s been bombarded with massive amounts of radiation the results have either been gruesome or wholly fantastical (see: any superhero origin story). But recent research out of Japan indicates that a barrage of electrons could actually help scientists revolutionize microbiology and, more excitingly, space travel. The experiment, conducted by a team from the Hamamatsu University of Medicine, found that the larvae of fruit flies hit with this electron rush were able to withstand an electron microscope’s hostile vacuum unharmed and even grew to be healthy adults. The results weren’t so rosy for the untreated group which, understandably, suffered a grislier fate: death by dehydration. The magic, it turns out, is in that subatomic spray, as the group treated with an electron shower benefited from a polymerizing effect or, more plainly, a bonding of molecules just above the skin’s surface that yielded a tough, protective nano-layer measuring between 50- to 100-billionths of a meter thick. Finesse that technique some and it’s easy to why one NASA scientist thinks this could lead to the creation of a super-thin “space shield… that could protect against dehydration and radiation.”

The process is still far from foolproof, however, seeing as how an increase in the microscope’s resolution requires an equal boost in radiation — all of which is fatal to the insects. So, in order to go deeper and get a more close-up view of the larvae’s internals, the team’s currently exploring new methods of fabricating these “nano-suits” using an array of chemicals. If you’re wondering just how far-off we are from practical human application, then consider this: the amount of radiation required to form the bonded layer is akin to “sunbathing naked on the top of Everest under a hole in the ozone.” Which is to say, keep dreaming. And get Jeff Goldblum on the phone while you’re at it… we have a promising idea for a Return of the Fly sequel.
