Advancements in robots have already changed our lives in many ways.  Most of the time you don’t even notice it, but automated robotic systems have added efficiency and speed to countless industries.  Researcher at Cornell University have developed what they say is a first of its kind robot.  They move via laser impulses and are small enough that they are right at home next to microorganisms that already live inside of us. The hope of these tiny robots is that they may be capable of doing things that even a well trained doctor simply can’t. Itai Cohen the Lead author of the study joined Tom on the show.
