Our subway trains are controlled by tireless robo-drivers. And thanks to the continual miniaturization of electronics and micro-mechanics, there are already robot systems that can perform some kinds of brain and bone surgery with submillimeter accuracyfar greater precision than highly skilled physicians can achieve with their hands alone.

　　But if robots are to reach the next stage of laborsaving utility, they will have to operate with less human supervision and be able to make at least a few decisions for themselvesgoals that pose a real challenge. While we know how to tell a robot to handle a specific error, says Dave Lavery, manager of a robotics program at NASA, we cant yet give a robot enough common sense to reliably interact with a dynamic world.
