Ten residents of Tokyo, all of them paralyzed, spent several weeks in November and December working as waiters at an establishment called DAWN Café. Except they weren't actually there in person. Instead, they did their serving and order taking using the 4-foot-tall OriHime-D robot, which they controlled from their homes. Those with the most severe paralysis can direct the waiter bots using only simple eye movements. The pop-up restaurant, which could become permanent in 2020, shows just how far robotic technology has come.
