SKIRMISHER

Harnessing the electrical impulses of sight, scientists have built a robot guided by the brain and eyes of a moth.

As the moth tracks the world around it, an electrode in its tiny brain captures faint electrical impulses that a computer translates into action.

The moth, immobilized inside a plastic tube, was mounted on a 6-inch-tall wheeled robot. When the moth moved its eyes to the right, the robot turned in that direction.
