OK, let's get started. First. I'd like to review a basic definition of robot. Then we'll look at some examples of robots in history. And finally, we'll look at how robots are being used today.
One simple way to define robot is to say it's a machine, a mechanism that can move automatically, or by itself. Many people think a robot needs to look or think like a human, but as you'll see in my examples, that's not always true. Sometimes robots look like people, but not always. OK?
