fly robot A team at Harvard lead by Robert Wood has created a fly-like robot that really flies like, er, a fly. It only weighs 60 milligrams. It’s just a start, since it has no onboard power nor can it be controlled (it flies on a tether to keep it straight). But it does fly! Future uses for such flybots (besides the obvious espionage uses) include the ability to fly into areas to detect toxins, etc. Neat.
