1:

but first I’d like to review a basic definition of robot.

2:

So, robots are programmable; they’re controlled by computers.

3:

4:

in other words, robots do work that people can’t do because it’s too dangerous or difficult or don’t want to do, because it’s dirty or dull.

5:

it’s impossible for a person to do a task like this as efficiently as a robot.

6:

robots also perform work that is too dirty or too dangerous for humans.

7:

robots can explore volcanoes, where it’s very hot.

8:

people obviously can’t go into a volcano.

I’ll leave you with that thought.

10:

next time we’ll talk more about the benefits and dangers of living with robots.
