Listen and read the email from an engineer at Powell Technologies again. What will be the main role of the autonomous, serial robot?

Listening

Listen to a telephone conversation between two engineers. Choose the correct answers.

       1 What is the dialogue mostly about?

A fixing a serial robot

В the main uses of serial robots

С designing and building a serial robot

D the main function of an enabling device

       2 What is the problem with the robot?

A the pendant is not moving correctly

В the mathematical calculations are incorrect

С the enabling device will not activate

D the actuators aren't working properly

Listen again and complete the conversation.

E 1: So, Lisa What’s wrong with your 1 _____ ______?

E 2: Its 2 _____ aren't responding. Do you have any advice?

E 1: Well, in my experience, the 3 ______ _______is often the problem.

E 2: I checked that. The enabling device turns on properly. But the actuators don't respond when you move the

pendant.

E 1: Okay. And all your mathematical calculations are correct?

E 2: They are. I checked the 4________ _________ twice.

E 1: 5 ____ _____your equality constraints? What’s

the value of those?

E 2: I set them to seven.

       Speaking

With a partner, act out the roles below based on Task 7. Then, switch roles.

USE LANGUAGE SUCH AS:

What's wrong with your serial robot?

The enabling device turns on properly.

I checked the dynamic model twice.

Student A: You are an engineer. Talk to Student В about: • problems with the robot • calculations • equality constraint

Student B: You are having problems with your robot. Answer Student A's questions.

 

Writing

Use the conversation from Task 8 to fill in the notes.
