Cutting Edge

A humanoid robot has been deployed to a supermarket in Japan to help senior shoppers with their grocery purchases.

The modified version of the Robovie II robot developed by Japan's Advanced Telecommunications Research Institute International, or ATR, is working as a temporary shopping assistant at Apita-Seikadai supermarket in Kyoto until March. It's another experiment to test the viability of advanced personal robots in everyday situations.

Robovie can wirelessly receive a list of items selected beforehand by the customer, carry the shopping basket, and make recommendations about what to buy.

In the video below, the robot slowly follows a … Read more

Iraqi insurgents have reportedly intercepted live video feeds from the U.S. military's Predator drones using a $25.95 Windows application that allows them to track the pilotless aircraft undetected.

Hackers working with Iraqi militants were able to determine which areas of the country were under surveillance by the U.S. military, The Wall Street Journal reported Thursday, adding that video feeds from drones in Afghanistan also appear to have been compromised.

Meanwhile, a senior Air Force officer said Wednesday that a wave of new surveillance aircraft, both manned and unmanned, were being deployed to Afghanistan to bolster "eyes in the sky" protection … Read more

Earlier this week I had the very awesome opportunity to attend the first flight of the Boeing 787 Dreamliner in Seattle. This is usually Daniel Terdiman's beat, but knowing that I'm a huge airline geek, CNET let me take a break from cell phones to cover the first flight. Daniel wrapped up the event with blogs and great photos of the take-off and landing--I helped by shooting the take-off video--but I also had the opportunity to visit the Dreamliner Gallery.

The gallery, which is located in Everett, Wash., just near Paine Field where the 787 was … Read more

Let's say you find a lump somewhere and decide to go in for an exam. And let's say there was a little box to check that allows you to get a shot that targets and kills cancerous cells right then and there, no surgery, no waiting, and possibly no radiation or chemo therapy down the road. Would you check the box?

Since time matters when it comes to cancer, the creation of a single nanoparticle--traceable in real time via MRI--that tags and zaps cancer cells all in one procedure has a team of researchers raising their eyebrows in … Read more

The clever folks at MIT have developed a smart wheel that could give bicycle riders a 21st century boost.

Unveiled Tuesday at the Copenhagen Conference on Climate Change, MIT's new Copenhagen wheel is trying to do its part to help the environment by making bike riding easier and more enjoyable.

The wheel's battery can store energy as you step on the brakes and then return that power back to help you climb a hill or boost your speed. A sensor inside the hub measures your effort when you ride. As you pedal forward, the sensor tells the wheel's electric motor to give you a boost. When you hit the brakes, the motor regenerates, slowing you down and recharging the batteries. The goal behind this design is to encourage people to bike farther distances, relying less on gas-guzzling transportation.

"Over the past few years we have seen a kind of biking renaissance, which started in Copenhagen and has spread from Paris to Barcelona to Montreal," said Carlo Ratti, director of the MIT Senseable City Laboratory and the Copenhagen Wheel project, in a statement. "It's sort of like 'Biking 2.0'--whereby cheap electronics allow us to augment bikes and convert them into a more flexible, on-demand system."

Beyond giving you an energy boost, the wheel has other secrets in its bright red hub. Using sensors and a Bluetooth connection, the wheel can talk to an iPhone mounted on the handlebars. Through an iPhone app, you can check your speed, direction, and distance traveled. The wheel can also monitor traffic conditions and smog and even keep track of your bicycling buddies.

The Copenhagen wheel embeds all the required electronics inside the hub, so no other gadgets need to be added to the bike frame. A special spoking method devised by the team also lets you install the hub on any rim.

Any existing bike can be retrofitted with the wheel. In fact, the MIT team sees it as a plug-and play-device, one that any bike owner should be able to easily install as a back wheel.… Read more

Have you noticed how many times bullets miss their mark in the movies?

If you need to shoot a bank robber, Sean Bean, John Malkovich, or even an ugly looking two-dimensional chap on a distant target, it seems as if it's very much a hit-or-miss affair.

This, believes professor Timothy Kraft of the University of Alabama, Birmingham, is because no one has re-thought the basic principles of a pistol sight for a hundred years.

Kraft, who happens to rather enjoy shooting and is good at it, dedicated some of his finest mental armory to solving the problem. As he describes it on the university's site, … Read more

Japanese robot maker Kokoro, best known for its Actroid line of ultra-lifelike androids, will make robot clones of people in a special limited-time offer.

The New Year promotion is being offered via select department stores in Japan. People willing to pay about $225,000 can have themselves recreated in robot form, with their robot clone having exactly the same face, hair, eyes, and body.

Kokoro will also model the buyer's voice, facial expressions, and upper-body movements to create the most lifelike doppelganger possible.

The Actroid and Geminoid androids are powered by a quiet air servo system that moves their … Read more

Not so long ago, large, numerate brains got together to create a mathematical formula for choosing the right wife.

Not content with satisfying the need for perfection in human relationships, mathematicians have now dedicated themselves to creating equations for the perfect relationship with the physical world.

Yes, according to the Telegraph, a British math professor has created a formula for successfully slipping your car into a parking spot.

You might think this a trivial pursuit. You'd be right. However, Vauxhall Motors, which participated in this useful experience, claims that 15 percent of hardy Brits say that the the biggest … Read more

A certain American Airlines 757 pilot gave me and a couple of hundred others a very hard landing this week.

So my jaw finally began to cease chattering when I discovered NASA is beginning to work on dropping flying things from the sky to see if perhaps the impact can be absorbed.

NASA's Web site told me that it dropped a helicopter from 35 feet in order to see whether an expandable honeycomb cushion that NASA calls a "deployable energy absorber" could minimize damage to life, limb, and even nervous systems.

The MD-500's landing gear did … Read more
