Robot Flies

Science often imitates life. Insects are common in the world. Tiny critters crawling and flying about. Now we are genuinely making them. In the very early hours of the morning, in a Harvard robotics laboratory last summer, an insect took flight. Half the size of a paperclip, weighing less than a tenth of a gram, it jumped up a few inches, hovered for a moment on fragile, flapping wings, and then sped along a preset route through the air. It was not science fiction, it was a man made fly.
