Honda says brain waves control robot

In a step toward linking a person's thoughts to machines, Japanese automaker Honda said it has developed a technology that uses brain signals to control a robot's very simple moves.

In the future, the technology that Honda Motor Co. developed with ATR Computational Neuroscience Laboratories could be used to replace keyboards or cell phones, researchers said Wednesday. It also could have applications in helping people with spinal cord injuries, they said.

In a video demonstration in Tokyo, brain signals detected by a magnetic resonance imaging scanner were relayed to a robotic hand. A person in the MRI machine made a fist, spread his fingers and then made a V-sign. Several seconds later, a robotic hand mimicked the movements.

Further research would be needed to decode more complex movements.

The machine for reading the brain patterns also would have to become smaller and lighter — like a cap that people can wear as they move about, said ATR researcher Yukiyasu Kamitani.

What Honda calls a "brain-machine interface" is an improvement over past approaches, such as those that required surgery to connect wires. Other methods still had to train people in ways to send brain signals or weren't very accurate in reading the signals, Kamitani said.

Honda officials said the latest research was important not only for developing intelligence for the company's walking bubble-headed robot, Asimo, but also for future auto technology.

"There is a lot of potential for application to autos such as safety measures," said Tomohiko Kawanabe, president of Honda Research Institute Japan Co.

Asimo, about 50 inches tall, can talk, walk and dance. It's available only for rental but is important for Honda's image and has appeared at events and TV ads.

At least another five years are probably needed before Asimo starts moving according to its owner's mental orders, according to Honda.

Right now, Asimo's metallic hand can't even make a V-sign. {Y! News}

Iran: A Rummy Guide

To borrow a phrase used for Iraq, there are 'things we now know we don't know.'Back in June 2002, as the Bush administration started pushing hard for war with Iraq by focusing on fears of the unknown—terrorists and weapons of mass destruction—Secretary of Defense Donald Rumsfeld explained that when it came to gathering intelligence on such threats, "absence of evidence is not evidence of absence." Elaborating, Rumsfeld told a news conference: "There are things we know that we know. There are known unknowns; that is to say there are things that we now know we don't know. But there are also unknown unknowns. There are things we do not know we don't know."Now there's a crisis brewing with Iran. And the same basic problem applies: what is known, what is suspected, what can be only guessed or imagined? Is danger clear and present or vague and distant? Washington is abuzz now, as it was four years ago, with "sources" talking of sanctions…
