Have you ever seen how a robot works? Where did you see it and what

Operations did it perform?

Mr. Kosov, a reporter from the University newspaper, is talking to Paul,

One of the students at this University. Listen to their dialogue and learn

What the students do at the practical classes in robotics.

Mr. Kosov: Paul, I'd like to talk to you. I'm interested in your practical classes in Robotics. Will you tell me about them?

Paul: Certainly. Yesterday we watched how a robot worked.

Mr. Kosov: Really? Had you seen robots before that?

Paul: Well, yes, I had, but only on TV. In reality it's an impressive sight.

Mr. Kosov: What had you done before you started your work?

Paul: Before that we had prepared all the necessary workpieces and tools in our laboratory.

Mr. Kosov: That's very clever of you and in general do you like your practical classes in Robotics?

Paul: Oh, yes. We learn a lot of interesting information about robot engineering and at these lessons we can carry out different experiments ourselves. For example, last time our teacher gave us a task to perform a series of experiments with a gripping device. Mr. Kosov: It sounds interesting. Have you finished your work yet?

Paul: Unfortunately, not yet.

Mr. Kosov: By what time will you have finished it?

Paul: I hope we'll have finished it by 4 o'clock today.

Mr. Kosov: Well, thank you very much. And good luck with your studies.

Paul: Thanks.
