This Cute Little Robot Fly Is The First Without A Wire
Mark Stone/University of Washington
Like an umbrella with a hole in it, you can’t do a whole lot with flying insect robots tethered to power sources.
Tiny airborne robots can sneak into hard-to-reach places that larger drones can’t, accomplishing some of the same goals, like surveillance and detecting trace chemicals like methane in the air. But they can’t do that if they’ve got big old cords sticking out of them.
