If you ever watched The Jetsons as a kid, you probably were enthralled by—but also a little skeptical of—the robotic contraptions, holograms, and other crazy-seeming inventions that propelled their lives every day. You can go ahead and suspend that disbelief now, because the next time you visit the hospital, you'll find that the world of the Jetsons is already here. Take, for instance, Gigi, the germ zapping robot that sweeps patient rooms for lingering infectious germs. Gigi, much like Judy from the Jetsons, is operated remotely, blasting a disinfecting ultraviolet light that offers zero chance for any transference of infectious disease.
