VIDEO: Man uses mind-controlled robotic arm

On Thursday, we got a look at video of Eric Sorto - who is paralyzed in his arms and legs - grabbing and drinking his first beer using a robotic arm.

That arm is controlled by his mind.

We have seen similar technology before but this one is controlled by a device implanted in the part of the brain that's responsible for intuitive thought.

The researchers at Cal-Tech and the University of Southern California, say this allows for smoother movement.
