Harvard university has been working on tiny flying robots as part of their robobee project. But their latest iteration is incredibly impressive, but figured some of you would find it more interesting since it’s more like a quadcopter now!

I am curious what kind of power they use, the article does not seem to mention

Yes, that is awesome!
My other passions are flyfishing and fly tying. Those little wings flapping in the surface tension just imitating a small mayfly struggling to to get airborne again would make a killer fly pattern.
Great thread
