Amoeboid Robot Moves Autonomously Without Centralized Brain 38

Posted by Soulskill from the let's-build-something-creepy dept.
An anonymous reader sends this excerpt from MIT's Technology Review: "A new blob-like robot described in the journal Advanced Robotics uses springs, feet, 'protoplasm' and a distributed nervous system to move in a manner inspired by the slime mold Physarum polycepharum. ... Researcher Takuya Umedachi of Hiroshima University has been perfecting his blob-bot for years, starting with early prototypes that used springs but lacked an air-filled bladder. ... Umedachi modeled his latest version on the 'true' slime mold, which has been shown to achieve a 'human-like' decision-making capacity through properties emerging from the interactions of its individual spores (abstract). Slime molds appear to have general computational abilities, and you've probably heard that they can solve mazes."

Reinventing the Clapper With a Knock-Based Home Automation Controller 92

Posted by timothy from the scratch-friend-and-enter dept.
An anonymous reader writes with a snippet from Hack a Day: "Clap On! Clap Off! was super awesome when The Clapper came out in the mid-eighties. Now [Mathieu Stephan] is trying to make the concept much more functional. He put together a controller that lets you knock on walls to control things around the house. It's called the Toktoktok project and uses small boxes to receive user input and control items like lamps and computers." As the project website points out, Stephan is keeping the project intentionally open.

Meet The Man Who Designed a Tablet Computer 15 Years Before the iPad 374

Posted by timothy from the flat-and-functional dept.
Doofus writes "The Washington Post has a profile of Roger Fidler, who 'invented' the tablet computer in the 1990s, while working as a visionary for newspaper firm Knight-Ridder. He is now embroiled in the Apple/Samsung legal war, as an expert witness. Fidler admits that other prior art influenced him, such as the tablets being used as computing devices in 2001: A Space Odyssey. Prior prior art."

When a Robot Becomes the Life of the Party 36

Posted by timothy from the perfect-for-next-mother's-day dept.
theodp writes "The rich are different; the geek rich are different-er. The WSJ's Emily Glazer reports that when Richard Garriott de Cayeux threw a costume party the night before his wedding in Paris, his 82-year-old mother — too frail to travel from her Las Vegas home — still dressed up as an Indian princess and attended the party using a $9,700 personal-presence robot from Anybots Inc. At the wedding reception the next day, Mama Garriott shook her robootie on the dance floor, encircled by kids and family. Telepresence robots aren't just for the likes of Sergey Brin anymore — companies like VGo, Xaxxon, Willow Garage, and iRobot have introduced personal-presence robots that range in price from $270 for a simple model to $50,000 for a machine that allows doctors to diagnose illnesses remotely. And, as an old NY Times article noted, they can also make fine Robot Overlords."

Third-Generation Apple TV Lands With a Thud 222

Posted by timothy from the that-dog's-not-so-shaggy dept.
DeviceGuru writes "Although generally overshadowed by the iPad 3 debut, Apple also introduced the third incarnation of its Apple TV streaming media players this week. Sporting a revamped icon-based UI, the third-generation Apple TV doesn't add much to its predecessor beyond a truly-HD 1080p video output mode. Although Apple TV is still not supported by an Apple Apps Store plug-in apps ecosystem, its new UI (available as a free update for 2nd-generation Apple TVs) does seem to imply that this capability is coming soon. Meanwhile, Roku is gearing up for a $50M IPO, so this cord-cutting story is far from over."

The Lytro Camera: Impressive Technology and Some Big Drawbacks 220

Posted by timothy from the light-field-of-dreams dept.
waderoush writes "The venture backers behind Lytro, the Silicon Valley startup that just released its new light field camera, say the device will upend consumer photography the way the iPhone upended the mobile business. This review takes that assertion at face value, enumerating the features that made the iPhone an overnight success and asking whether the Lytro camera and its refocusable 'living pictures' offer consumers an equivalent set of advantages. The verdict: not yet. But while the first Lytro model may not an overnight success, light field cameras and refocusable images are just the first taste of a revolution in computational photography that's going to change the way consumers think about pictures."

Nanowire Forests Use Sunlight To Split Water 56

Posted by Soulskill from the just-have-to-keep-the-nanosquirrels-away dept.
An anonymous reader sends this excerpt from IEEE Spectrum's Nanoclast blog: "One of the fundamental problems with fuel cells has been the cost of producing hydrogen. While hydrogen is, of course, the most abundant element, it attaches itself to other elements like nitrogen or fluorine, and perhaps most ubiquitously to oxygen to create the water molecule. ... Now researchers at University of California, San Diego have developed a quite different approach to mimicking photosynthesis for splitting water molecules by using a 3D branched nanowire array that looks like a forest of trees. ... The nanowire forest [uses] the process of photoelectrochemical water-splitting to produce hydrogen gas. The method used by the researchers, which was published in the journal Nanoscale (abstract), found that the forest structure of the nanowires, which has a massive amount of surface area, not only captured more light than flat planar designs, but also produced more hydrogen gas."

Teaching Robot Learners To Ask Good Questions 93

Posted by Soulskill from the why-must-you-kill-all-humans dept.
garthsundem writes "I disagree with this article's opening line: 'Within a decade, personal robots could become as common in U.S. homes as any other major appliance.' Haven't we been promised this since the 50s? But I'm fascinated by the rest — how do you teach humans to teach robots? Or, more precisely, how can you teach robots to teach humans to teach robots? The idea that designers can put a flexible platform in a robot, allowing users to determine functionality, is pretty interesting. The lead researcher for this project said, 'People are not so good at teaching robots because they don't understand the robots' learning mechanism. It's like when you try to train a dog, and it's difficult because dogs do not learn like humans do. We wanted to find out the best kinds of questions a robot could ask to make the human-robot relationship as 'human' as it can be.'"

Google Works On Kinect-Like Interface For Android 49

Posted by Soulskill from the operating-phones-becomes-more-like-voodoo dept.
bizwriter writes "A patent filing made public last week suggests that Google may be trying to implement a motion-detection interface, like Microsoft Kinect, for portable electronic gadgets. The patent application is for technology that turns a mobile device's camera into a motion-input system. In other words, it could be goodbye to fingerprints and streaks on the front of your tablet or smartphone. Google could incorporate such a feature into Android in general or keep it as a differentiating advantage for its acquisition of Motorola."

Japan's Nuclear Energy Industry Nears Shutdown 267

Posted by Soulskill from the less-power-to-the-people dept.
mdsolar sends this quote from an article at the NY Times: "All but two of Japan's 54 commercial reactors have gone offline since the nuclear disaster a year ago, after the earthquake and tsunami, and it is not clear when they can be restarted. With the last operating reactor scheduled to be idled as soon as next month, Japan — once one of the world's leaders in atomic energy — will have at least temporarily shut down an industry that once generated a third of its electricity. With few alternatives, the prime minister, Yoshihiko Noda, has called for restarting the plants as soon as possible, saying he supports a gradual phase-out of nuclear power over several decades. Yet, fearing public opposition, he has said he will not restart the reactors without the approval of local community leaders."

'Of Course We Are In a Post-PC World,' Says Ray Ozzie 399

Posted by Soulskill from the you-can-pry-my-pc-from-my-cold,-dead-hands dept.
An anonymous reader writes "Speaking at a tech conference in Seattle this week, former Microsoft Chief Software Architect Ray Ozzie had some interesting things to say about the state of the computing industry. 'People argue about "are we in a post-PC world?" Why are we arguing? Of course we are in a post-PC world. That doesn't mean the PC dies, that just means that the scenarios that we use them in, we stop referring to them as PCs, we refer to them as other things.' Ozzie also thinks Microsoft's future as a company is strongly tied to Windows 8's reception. 'If Windows 8 shifts in a form that people really want to buy the product, the company will have a great future. ... It's a world of phones and pads and devices of all kinds, and our interests in general purpose computing — or desktop computing — starts to wane and people start doing the same things and more in other scenarios.'"

Robot Firefighter To Throw Extinguisher Grenades 78

Posted by Soulskill from the not-a-big-step-from-throwing-actual-grenades dept.
S810 writes "Discovery News is running an article about the U.S. Navy developing a robot capable of 'throwing extinguisher grenades.' From the article: 'SAFFiR would need finger and hand coordination to wrestle fire hoses into place or accurately throw extinguisher grenades. It similarly would need the sure-footed balance of a veteran sailor's sea legs to confidently walk the wave-tossed decks of warships. An infrared camera could allow such a robot to see through smoke-filled hallways, and perhaps it could detect the location of fires through gas sensors. The robot's battery is intended to pack enough energy for half an hour of firefighting action.'"

2000x GPU Performance Needed To Reach Anatomical Graphics Limits For Gaming? 331

Posted by Soulskill from the perfectly-photorealistic-rocket-jumps dept.
Vigile writes "In a talk earlier this year at DICE, Epic Games' Tim Sweeney discussed the state of computing hardware as it relates to gaming. While there is a rising sentiment in the gaming world that the current generation consoles are 'good enough' and that the next generation of consoles might be the last, Sweeney thinks that is way off base. He debates the claim with some interesting numbers, including the amount of processing and triangle power required to match human anatomical peaks. While we are only a factor of 50x from the necessary level of triangle processing, there is 2000x increase required to meet the 5000 TFLOPS Sweeney thinks will be needed for the 8000x4000 resolution screens of the future. It would seem that the 'good enough' sentiment is still a long way off for developers."

IBM Optical Chip Moves Data At 1Tbps 127

Posted by timothy from the whooomph-there-it-was dept.
snydeq writes "IBM researchers have developed a prototype optical chip that can transfer data at 1Tbps, the equivalent of downloading 500 high-definition movies, using light pulses, the company said Thursday. The chip, called Holey Optochip, is a parallel optical transceiver consisting of both a transmitter and a receiver, and is designed to handle the large amount of data created and transmitted over corporate and consumer networks as a result of new applications and services. It is expected to power future supercomputer and data center applications, an area where IBM already uses optical technology." User judgecorp links to more coverage, writing "The record was achieved because 24 holes in the chip allow direct access to lasers connected to the chip."

The problem is already nearly fixed, but new jacks need to be sourced for subsequent shipments, so those could be delayed slightly. 'It's inevitable, isn't it — you're freewheeling along perfectly happily and then you get a puncture,' said spokeswoman Liz Upton, apologizing for the delay."

From the article: 'As one of the three big makers of graphics chips for PCs--the other two are Intel and AMD, both of which are longtime Linux Foundation members--Nvidia's increased participation in Linux could be big news for users of the free and open source operating system. Nvidia has long taken a closed approach to Linux drivers for its graphics cards, offering only a proprietary one and declining to participate in the open source Nouveau driver project, which has depended instead on reverse engineering.'"
