Miniscule robotic drones might be the future, but they’ve been tricky to get off the ground. Until now, any wing-flapping insect robot had to have a power source, making it too heavy to lift off with its tiny wings. Now, however, researchers at the University of Washington have found a way to transmit power to a flying robotic insect (lovingly dubbed RoboFly) via laser, obviating the need for a separate power supply.
