Robovie-II, the Robot That Helps You Buy Groceries

The ease and variety of online shopping enabled by the first dot-com explosion cast technology as the killer of in-store retail. But in Japan, with its aging population and unique consumer culture, technology facilitates grocery shopping, in the form of retail assistance robots like Robovie-II. Part of a larger network of sensors and wireless devices, Robovie provides assistance to elderly shoppers making their rounds.

The process begins at home, with the user entering their shopping list into a specialized mobile device. When the shopper arrives at the store, the robot senses the device and greets the user. Then the robot follows the shopper around the store, carrying the load, reminding the shopper of the items on the list, and recommending additional products to pick up.

At present, the system remains in the testing phase, with robot helpers assisting elderly shoppers at Apita-Seikadai supermarket in Kyoto, Japan, through March of next year. To see Robovie in action, check out the video below.

Holiday Deal: Japanese Store Sells Custom Robot Lookalikes

Just plunk down $225,000 at a Japanese department store and get your own robot twin

Japan's obsession with robotics has led to one of the ultimate sci-fi fantasies (or nightmares): life-size robots customized to look like you and speak in your own voice. The department store Sogo & Seibu wants to deliver that dream to any interested customers starting as soon as next month, but first it plans to test the waters by making this an exclusive two-robot deal. If more than three buyers show interest in having robotic doppelgangers, a lottery system kicks in.

Each robot twin is made of silicone and will only be able to move its upper body. So unlike Dwight of The Office, you won't have to request a six-foot extension cord that prevents the robot from chasing you.

The new lookalike bots come courtesy of robot-manufacturer Kokoro, which has showcased its androids at past robot expos. In this case, buyers can also supply their own recorded voices to ensure that their robot twin comes armed with witty repartee.

This still seems a far cry from the freaky fembots of the revisionist Stepford Wives and Austin Powers, not to mention the classic Metropolis. So as long as you have $225,000 to spend for an "actroid," feel free to knock yourself out -- if boredom takes over, you can always stuff the robot into a Santa suit.

Video: Wild Grouses Enticed into Mating With Sexy Fembot

It could happen to you

One of America's strangest mating rituals, the chest-puffing, squeaking dance of the sage grouse, is getting closer attention, thanks to a pretty little fembot.

The sage grouse, which is sort of like a more interesting type of chicken, has long captivated scientists as well as tourists because, of its elaborate mating habits. A group of researchers have infiltrated the grouse world using a custom-designed "fembot" -- a robotic bird on wheels with a camera nestled in her breast.

During breeding season, males gather in open areas called leks, which can be found throughout most of the rural West. The males puff their chests, strut like peacocks, and make throaty whistling sounds, all in an effort to attract females, who walk around the lek and survey the goods.

Gail Patricelli, an animal behaviorist at the University of California-Davis, is now reviewing four mating seasons' worth of video recordings captured by a fembot she designed, according to Science Nation, a National Science Foundation publication.

The fembot is basically half a sage grouse body attached to a small audio recorder, a microphone and a camera. Scientists use a remote control to roll her out on a small train track set up on the lek. Like the creepy feminina machinas in Austin Powers, a little bob of the head is enough to get the males' attention. Their ensuing fights and bizarre displays are then caught on film.

Part of the reason the fembot is so successful is that male sage grouses are particularly randy, hoping to mate with as many females as they can, as often as possible. The female grouses are the picky ones, blowing off most suitors. Researchers estimate only about one in 10 male sage grouse mate in a given season. The ones who do mate are veritable prairie players -- Patricelli told Science Nation that the top male in her study mated 47 times in one season.

Sage grouse studies could provide a model to better understand the evolution of animal communication, Patricelli said.

"It helps us understand the evolution of very basic behaviors like social skills and social interactions and two-way conversations, and how these evolve by the process of sexual selection," she said.

Darpa's Cyborg Insect Spies, Now Nuclear-Powered

When you write for Popular Science, it's easy to become desensitized to wild and crazy future tech. To wit: When I first heard that Darpa wanted to develop cyborg insects to carry surveillance equipment, I thought "ok, cyborg insect spies are pretty cool, but not blowing me away."

Then today, Cornell researchers working on the program unveiled a prototype transmitter for the cyborg bugs that runs on radioactive isotopes. Nuclear powered cyborg insect spies? Ok, now you have my attention.

While the bugs can fly under their own power, any electronics added to the lil' sentry for keeping in contact with HQ or other cyborg drones in the swarm need some kind of external power. And a radioactive isotope working as a nuclear battery does the trick perfectly. The isotope in question is Nickle-23, a barely radioactive isotope that doesn't emit enough radiation to harm a human. However, even slight beta-particle emissions are powerful enough to fuel the on board electronics of our arthropod cyborgs for up to 100 years.

For fun, let's see that cyborg moth flight test from September one more time, shall we?

Right now, those electronics only include a 5-milliwatt RFID transmitter. But eventually, the cyborgs will carry a full suite of sensors, and hopefully, since we are talking about nuclear powered cyborg insects going to war, some kind of death ray.

Pneumatic Ball-Levitating 'Bot Preps Produce, Wins at Beer Pong

Using an air jet to make a ball appear to levitate is an old physics lab trick; the air rushing around the ball traps it in a low-pressure pocket. But guiding "floating" balls through an obstacle course of hoops, making asymmetrical objects like apples and water bottles float as carefree as perfect spheres, or launching balls across a room with precision accuracy? That's impressive.

A pair of grad students at the University of Illinois Urbana-Champaign have done exactly that, using a computer to control a gimbaled air-jet system with two degrees of motion to not only "levitate" two different-sized balls at once, but also to make them follow difficult trajectories through obstacles, and even land in a small bucket of water all the way across the room.

Stereo vision cameras keep tabs on the objects, feeding a control algorithm data that allows the jet to keep objects at equilibrium and under control. Oh, and it peels onions. Don't believe us? Check out the video below. It makes your Slap Chop look pretty simple by comparison.

MIT Plans to Rebuild Artificial Intelligence from the Ground Up

After 50 years and countless dead ends, incremental progress, and modest breakthroughs, artificial intelligence researchers are asking for a do-over. The $5 million Mind Machine Project (MMP), a patchwork team of two dozen academics, students and researchers, intends to go back to the discipline's beginnings, rebuilding the field from the ground up. With 20/20 hindsight, a few generations worth of experience, and better, faster technology, this time researchers in AI -- an ambiguous field to begin with -- plan to get things right.

The study of AI is a half a century old, beginning with lofty expectations at a 1956 conference but quickly fragmenting into different specializations and sub-fields. The MMP wants to roll back the clock, fixing early assumptions that are now foundations of the field and redefining what the objectives of AI research should be.

The fundamental problem, it seems, is that the mind, memory and body function both together and separately to solve any number of problems, and the way they work together (and alone) varies from problem to problem. The human mind alone applies various systems and functions to any given problem. Many AI solutions have attempted to solve all the problems with one system or function rather than multiple systems working together as in the human mind, a "silver bullet" approach that hinders real progress.

Likewise, when it comes to memory, researchers have created models that work more like computers, where everything is either one or zero. Real memory is filled with gray areas, ambiguities and inconsistencies, but functions in spite of not always being congruent. MMP researchers also intend to bring computer science and physiology together, forcing computers to work within the confines of physical space and time just like the body does.

The team even proposes discarding the Turing Test, the long-recognized standard for determining artificial intelligence. Instead, MMP researchers want to test for a machine's comprehension of a children's book -- rather than a human's comprehension of another human being -- to gain a better understanding or the AI's ability to process and regurgitate thought.

It's a big-picture approach to a big challenge, and while it's perhaps unlikely that the team can re-imagine AI in the ambitious five-year window they've given themselves, it very well could shore up some of the loose underpinnings of a discipline that has boundless potential to shape a better world (or, for you SkyNet junkies, limitless potential to destroy it). If nothing else, it's a responsible admission from the scientific community that they simply don't have it quite right, that we need to rethink what we think we know.

Climatologists, take notes.

Air Force Admits Existence of Outed Skunkworks Stealth Drone

A U.S. Air Force official provides details on the mysterious aircraft spotted in Afghanistan

A mysterious, unidentified drone that bore strong resemblance to previous stealth aircraft has finally been revealed. The U.S. Air Force confirmed its existence and identity to the Aviation Week last Friday, after photos circulating online had caused much speculation among defense buffs.

Informally dubbed the "Beast of Kandahar," the tailless flying wing apparently is an RQ-170 Sentinel designed to provide recon and surveillance for warfighters on the frontlines. Online photos had shown the drone at a General Atomics Aeronautical Systems's hangar in Kandahar, Afghanistan.

The 30th Reconnaissance Squadron also operates the RQ-170 at Tonopah Test Range -- a location perhaps better known as Area 52 -- under the aegis of Creech Air Force Base in Nevada.

The unmanned aerial system (UAS) comes courtesy of Lockheed Martin's Skunk Works, which has worked on the U-2 and Blackbird spy planes as well as a swimming spy plane for the U.S. Navy. Lockheed had previously displayed a different stealth drone design that bore resemblance to the Reaper drones currently flying missions in Afghanistan.

The Ares technology blog points out that the stealth features suggest a drone meant for tactical operations in support of combat troops, rather than sneaky intelligence-gathering.

Meanwhile, the UK has launched its own call for a laser-toting stealth UAS. We'll let you know when those designs leak out.

Robot Bartender Pours Your Drink Based on Your Tetris Skill

An engineer showcases interactive drink-mixing video games for the upcoming Roboexotica event

Robots, alcohol and video games make one tantalizing combination to put on distant-future Christmas lists. Now geek boozers are in luck: the one-man Nonpolynomial Labs has developed interactive versions of Mario and Tetris that incorporate a robotic bartender to mix up drinks during real-time play.

The interactive games come courtesy of Kyle Machulis, a self-described "mild-mannered engineer" who tackles some decidedly unorthodox garage projects that have included a "Moaning Lisa" sensor-feedback mannequin and a "LifeCycle" that uses an exercise bike to drive virtual vehicles in Second Life. He created "Adult Mario" and "Bartris" to showcase in the upcoming Roboexotica event held in Vienna, Austria, where robots display their cocktail mixing skills.

"Adult Mario" looks like a typical game of Mario Bros., except with a few interactive twists. Jumping on an enemy causes players to receive a small bit of rum in their cup. Grabbing coins adds a small squirt of Coke to the mix. Reaching the end-level flagpole triggers a shaking motion for as long as Mario slides down the pole, and adds an additional kick of rum during that time for good measure.

There are also less "adult" interactive elements, such as fans blowing into players' faces when they run Mario faster through the game.

"Bartris" plays like a normal game of Tetris with falling puzzle blocks, except that brown pieces represent Coke, gray pieces represent rum, and blue pieces represent water. The robotic bartender mixes accordingly.

"So you actually have the chance of making a drink that absolutely sucks," Machulis says in a video.

We also like the different "Bartris" modes, which include "Booze mode" (no water pieces dropped) and "Designated Driver mode" (only water pieces drop). And if you make a drink that's too stiff or too watery for your tastes, you only have yourself to blame -- not like playing with that straitlaced SOBEaR robot.

Robotic Sea-Glider Achieves First Unmanned Underwater Transatlantic Crossing

Cold robotic purpose can apparently break records as well as human fortitude

Charles Lindbergh may have shown human fortitude by flying across the Atlantic in his "Spirit of St. Louis," but now he has robotic company when it comes to transatlantic records. An underwater robotic glider built by Rutgers University students and scientists has achieved the first underwater robot crossing, after traveling beneath the waves for 221 days.

Rutgers researchers joined some Spanish colleagues today aboard the "Investigador" ship to recover the drone, after launching it on April 27, 2009 off the coast of New Jersey. The submersible bot made its 4,591-mile journey at the slow but steady pace of 4 centimeters per second.

Scarlet Knight: There and back again Ā Rutgers University

Named "The Scarlet Knight" for Rutgers sports -- despite its fine yellow appearance -- RU27 technically already claimed its transatlantic record on Nov. 14 after 201 days at sea. But the Rutgers team clinched the accomplishment after recovering the scarlet lady, and reportedly gave her a dose of champagne to celebrate.

Rutgers University alone has a small underwater fleet of up to seven gliders operating off the coast of New Jersey, with one even cruising around the Antarctic. The U.S. Navy has likewise deployed a number of drone submersibles (not to mention sea mammals), and private companies may also soon send out swarms of underwater explorers for oil prospecting.

Looks like Scarlet won't be too lonely the next time she decides to take a dip.
