We know there are many different kinds of robots and people want different robots to do different jobs. Suppose you are a robot scientist and you are going to design a robot pet. What kind of robot do you want to design? What can your robot do? Please look at the three questions in the chart in Activity 5. Think them over. I’ll ask one to present his or her robot to the class. Let them think for a while. Then ask one good student to present his or her design to the class. He or she may say like this. I am going to invent a robot dancer. It will look like a very pretty girl. I hope my robot can dance to different kind of music. When people are tired and want to listen to some music, my robot can perform dancing while the music is on. And my robot doesn’t need any other kind of power except the sound of the music. Then ask the whole class to discuss their robots in groups of four and fill in the chart with the information about the robots. Ask one or two students to present their designs to the class. If time permits, get students to make drawings of their robot pets or other robot ideas. Sample answers
