Chapter 4 Worksheet 4.7

Listen to Audio 4.3 Andre is describing his robotic arm. Then, answer the questions that follow.

Good morning, my friends. I’m going to show you what I have created from used materials. I call it “The Robotic Arm”. This arm is made of cardboard, straws, elastic, and strings. With this arm, you can take things without really touching them.

The arm is just like our hand. I can say that it is the extension of our lower arm. We put it on our wrist. There is a piece of elastic to hold the robotic arm. It is designed to follow our hand’s movement. The strings are attached to our fingers so we can move the robotic arm easily. We move the fingers by pulling the strings.

The topic of the talk is ....

• how to make a robotic arm

• creating something from used materials

• a robotic arm

• how to operate a robotic arm

From the text, we can conclude that if we want to move our

right index finger, we should ....

• fasten the elastic on our wrist

• move our all right fingers together

• pull the strings connected to our index finger

• attach the strings correctly
