Artificial Intelligence, real-life applications

Like many of the students around them, robots at Carnegie Mellon University are constantly learning -- learning how to think, how to move, and how to be more like humans. "It's sort of this wonderland of innovation," says 60 Minutes producer Nichole Marks in the video above. "Everywhere you go, every corner of the campus, there are robots -- robots in the hallways, robots picking things up, robots talking to you." Marks and correspondent Charlie Rose visited the Carnegie Mellon campus in Pittsburgh while reporting their two-part story on artificial intelligence, or A.I., for this week's episode of 60 Minutes. What they found in the old steel town was a glimpse into the future, says Rose.
