post Inventors develop transistor to change color of any surface, your face notwithstanding

Filed under: Gadget Reviews — admin @ 9:04 am

Color shifting has been a pipe dream for about as long as alchemists have claimed their studies to be legitimate, but now a brilliant team from the New University of Lisbon can finally say a breakthrough has been found. Essentially, these inventors have conjured up a transistor that changes the color of practically any surface (paper, glass, plastics, ceramics and metals, just to name a few). For what it’s worth, this same team already has quite a bit of display cred, as it has developed technology currently used within Samsung panels. With the help of a few good men and woman at the University of Texas at Austin, the team was able to register for a patent right here in the US, and with any luck, they’ll be giving OLEDs and e-paper a run for their money before we can snap our fingers twice and run around the block. Check a video (narrated in Portuguese) after the break.

post Hunt begins for most scenic spots

The wisdom of crowds is being tapped to map the most scenic parts of England, Scotland and Wales.

Modelled on the HotOrNot website, ScenicOrNot presents visitors with snaps of rural and urban locations rather than people.

The presented images are rated on a one to 10 scale and the site aims to create a map of "scenicness".

The pictures are drawn from a database of 200,000 each of which is representative of 1km square of land.

Picture perfect

ScenicOrNot is a project of Mysociety, an organisation set up with the aim of increasing the transparency of democratic institutions through the development of online tools.

The goal is to use the data generated by user ratings to produce a map of "scenicness".

Speaking to Radio 4’s PM programme, Tom Steinberg director of Mysociety, said he was drawn to this method of collecting data because HotOrNot style rating systems are "incredibly sophisticated clever ways of doing online polling".

As the images are randomly presented to users it is much harder to manipulate the results. "You can’t besmirch places you don’t like", Mr Steinberg said.

Although the exercise is billed as a game, it has a serious side. Numerous policy decisions are influenced by whether or not a place is commonly regarded as scenic, because of this Mr Steinberg said the new data generated by the project would be made "open so that anyone can re-use it and play with it later on".

The site’s FAQ also states that the data will be used for a "secret project", though Mr Steinberg was not prepared to reveal what that would be.

The photos displayed on ScenicOrNot are sourced from images submitted to Geograph.org.uk a site that collects user generated, geographically representative, photographs and information for every square kilometre of Great Britain and Ireland.

The images vary in quality and Mr Steinberg is aware of the risk that ratings may reflect the skill of the photographer not the landscape.

"We encourage people quite strongly to discount any aspect of photographic skill," he said.

A limited number of latest results are posted on ScenicOrNot’s "leaderboard". For the moment it appears that unspoilt countryside is viewed as particularly scenic; by comparison the modern built environment seems to do relatively poorly.

Jon Wright, a senior case worker at the 20th Century Society, which aims to "safeguard the heritage of architecture and design in Britain from 1914 onwards", said he was intrigued by the project.

Mr Wright added that that urban areas and those of classically beautiful parts of the country are very different in character. He said: "Those views should be judged on their own terms."

The data could also be used to reveal places that are not scenic. Mr Steinberg said he was uncomfortable with highlighting the least lovely places in Britain.

He said: "Can you imagine how you’d feel if someone said to you of the 217,000 square kilometres in Britain you’re in the worst one"

post Robots of the future unveiled

April 28th, 2009

Filed under: Technology — admin @ 9:04 am

The World, WGBH Boston

Experts predict that an ageing world population and continuing global military conflicts will be the two main drivers of robot design and function in the coming years.

Speaking at the Robo Business 2009 Conference and Expo in Boston, Tandy Trower, the general manager of Microsoft Robotics, noted that in the next 40 years, the number of pensioners - those aged 65 and over - is set to increase by two billion worldwide.

With that ageing will come the need to help families and other caregivers cope with decreased mobility and chronic diseases such as Parkinson’s and Alzheimer’s.

Mr Trower said that robots could have a "profound impact" when it comes to helping seniors communicate with family members and each other, or reminding someone to take their medications.

"Even just having robots do lightweight transport of objects from one room to another, whether it’s grandma’s knitting or a cup of coffee, could be tremendously valuable."

This is not as far away as you might think, judging by some of the robots wandering around the Expo.

Robosoft, a French company, was showing off robuLAB10, a proof-of-concept robot that has been specifically designed to follow and assist an elderly person in their own home.

It comes equipped with a touch-screen computer, a voice interface, and special robot navigation software developed by Silicon Valley’s SRI International.

"The market for home-centric robots that provide assistance to the elderly is one of our priorities," says the head of Robosoft, Vincent Dupourque.

The company said it hopes to have large-scale deployment of such eldercare robots in the next three years.

Mr Trower noted that the Japanese might beat them to it.

Toyota, he pointed out, is developing an entire line of "assistive robots" and has plans to put them in car showrooms by 2010.

By then, predicts the Japanese Robotics Association, the global market for service and personal robots will reach $17bn (£11.4bn).

Robowar

However, the growing market for military robots dwarfs that figure and it showed on the Expo floor in Boston, where just about every company with a booth was touting what its robot could do on the battlefield.

Robots are, of course, already making an impact in warfare.

In Iraq, the US military is using robots to help defuse improvised explosive devices. In Afghanistan, tele-operated robots, not soldiers, are being sent into caves to scout for enemies.

"But what will the robot-inhabited battlefield of the future look like" asked retired Vice Admiral Joseph Dyer in a keynote address.

Vice Admiral Dyer thinks about this question quite a bit as he now serves as president of the government and Industrial Robots Division at iRobot, one of the leading suppliers of robots to the US military.

"Very integrated and very unmanned," was his answer.

"You’re going to see ships that arrive on foreign shores, that put in unmanned underwater systems to do anti-submarine warfare and clear mines.

"And then those systems will carry ground robots ashore, and will launch unmanned aerial vehicles. It’s going to dramatically reduce what would have been required of special operations folks."

Talon robot

And yes, Vice Admiral Dyer predicted, armed robots will be part of that picture, although they should not be autonomous. He argued that a soldier should always remain in control.

In fact, remote-controlled armed robots are already in the pipeline. Qinetiq, which supplies a line of robots to the US military and law enforcement agencies, refit its TALON model with a weapon.

"Certainly the soldiers in the field that recognise its value," said Ed Godere, head of the Technology Solutions Group at Qinetiq.

"But we always want a soldier in the loop, making those life-and-death decisions that a robot could never make."

Sentient

Robot autonomy, and its accompanying ethical dilemmas, is only one of the big issues facing robotics companies.

The other is a much more practical concern - power.

Walk the Expo floor in Boston, and you were sure to see people constantly plugging in their ‘bots, or regularly swapping out batteries.

These power concerns are changing the way people design their machines.

"Power consumption is one of our most difficult design considerations," said Brain Zenowich, who works for Barrett Technology.

"We designed our robot from the ground up, so that it would draw as little power as possible, knowing that the battery technology is going to take many, many years to catch up."

Mr Zenowich was demonstrating the company’s robotic arm and hand system, which allows a user to remotely manipulate objects and carry out tasks.

The new twist is that the user does not just see what he or she is doing, but also feels what the arm and hand are feeling.

"If it encounters an object along the way, you can know that, you can feel that," Mr Zenowich said.

"It gives you that much more freedom and flexibility to accomplish a task, when you have visceral, force-feedback from the robot."

Segway robot

One of the main selling points, he noted, is that the arm is able to run for almost a full day on just one lithium-ion battery.

Like just about every company at the Expo, Mr Barrett sees multiple markets for its ‘bot.

It is currently in service at hospitals in the US, helping doctors perform knee surgeries. But the company says a "ruggedised" version might be able to help soldiers remotely defuse roadside bombs.

And the market of the future for a robotic arm system with torque sensors and force control

"We went to an expo in Italy, and we had one guy come up to us and say ‘this would be perfect for making my shoes,’" Mr Zenowich said.

"That’s something we would never think of."
