A new type of flying robot is so tiny and lightweight — it weighs about as much as a toothpick — it can perch on your finger. The little flitter is also capable of untethered flight and is powered by lasers.
This is a big leap forward in the design of diminutive airborne bots, which are usually too small to support a power source and must trail a lifeline to a distant battery in order to fly, engineers who built the new robot announced in a statement.
Their insect-inspired creation is dubbed RoboFly, and like its animal namesake, it sports a pair of delicate, transparent wings that carry it into the air. But unlike its robot precursors, RoboFly ain't got no strings to hold it down. Instead, the miniature bot uses a lightweight onboard circuit to convert laser light into enough electrical power to send it soaring. [New Flying Robots Take Cues From Airborne Animals]

However, the cell doesn't store energy; the circuit must be within range of the fixed laser to generate power for the robot to take off, and once its cell moves beyond the laser's reach, RoboFly's flight is over.
Tiny, highly maneuverable robots like RoboFly could quickly flutter into crevasses where bigger aerial drones simply wouldn't fit. One possible task for future versions of RoboFly could draw even more inspiration from flies — particularly, their talent for tracking down "smelly things," study co-author Sawyer Fuller, an assistant professor in the Department of Mechanical Engineering at the University of Washington, said in the statement.
"I'd really like to make one that finds methane leaks," he said. "You could buy a suitcase full of them, open it up, and they would fly around your building looking for plumes of gas coming out of leaky pipes. If these robots can make it easy to find leaks, they will be much more likely to be patched up, which will reduce greenhouse [gas] emissions."
