This robotic insect is the first to fly independently from a power source and potentially is able to help humans find sources of pollution faster and safer than traditional methods.

In time, it could even be used to survey crops, detect wildfires, poke around in disaster rubble searching for survivors and sniff out gas leaks, especially global warming-fueling methane, a powerful greenhouse gas many times more potent than carbon dioxide. Engineers power RoboFly by pointing a laser beam at a photovoltaic cell (blue) above the robot.
