Man sends robotic arms with his brain

In an accident the American Les Baugh got lost both arms. But now he can for the first time in forty years again pick up a cup. He has a first: the first he armprotheses simultaneously control his brain
Researchers at the Johns Hopkins Applied Physics Laboratory in the US state of Maryland have been working for ten years in technology to the brain. through the nerves prostheses can control. This summer could subject their Baugh using this technology two armprotheses simultaneously control.

Surgery and ten days training
Baugh has undergone surgery to the nerves that once his arms and hands were aiming to reactivate. Next, the scientists examined the brain patterns emerged when he thought of certain arm movements and which nerves were activated thereby, allowing the robot arms could be programmed in this way. After a ten-day training Baugh could move various objects. “I am, in fact, than the computer,” said Baugh

Now:. Two arms simultaneously control
New on the technology of the Johns Hopkins Applied Physics Laboratory is existing nerves are reactivated and used as control of the robot arm. Baugh is the first to be able to control simultaneously for two robot arms, and thus to translate complex brain signals to intuitive movements. Scientists are excited: Baugh learned much more movements than scientists had anticipated and also the rate at which Baugh learned the moves was higher than expected

Only available in lab
Baugh, the prostheses currently used only in the lab. It takes him quite a lot of time to all the joints in his shoulders, elbows, wrists, hands and fingers to get exactly the right position. But the technology will make the next five to ten years much progress, promising scientists. Baugh:
