Robo-fly steadies flight with onboard sensor

A fly-sized flying robot doesn't crash and burn thanks to an onboard light sensor inspired by those of live flies and honeybees.

These insects have ocelli — three light sensors that are distinct from their compound eyes — that could help stabilize their upward flight by sensing the horizon or sun. When an ocelli-inspired sensor was strapped aboard a fly-sized robot, the sensor kept the robot steady during a 0.3-second climb, researchers report June 18 in the Journal of the Royal Society Interf...
