Back when I started writing about robots (get off my lawn, by the way), helicopters were big and complicated and dangerous and crashy. It’s kind of amazing that now (or at least, soon, hopefully) you can get a tiny little quadrotor that can stabilize itself in flight for just under $100. Or, to put it another way, for just under $10,000, you could get a hundred of ’em.
