The little birdie weighs in at less than an ounce and can fly in a figure eight, moving up, down, left and right. Next steps for its development -- which the researchers say will arrive by 2011 -- include the ability for it to hover mid-air, and have a small camera attached to it. Ultimately, its creators see the robot (which has cost around 2 million dollars to develop) being able to help s
