        NOVA Online | RoboBees to the Rescue

        As colony collapse disorder decimates beehives, scientists at Harvard University are developing mini drones, called RoboBees, to help pollinate our crops. Piezoelectric materials are used to convert electricity into motion to flap the wings, keeping the drones small and light and able to fly. Unfortunately, no one has yet invented a battery small enough or light enough to enable the drones to fly untethered to electric wires. Learn about robot bees in this video from NOVA Online.
