                      1.  Have you used a voice assistant like Alexa, Siri or Google Assistant? What did you ask it to
                          do?

                      2.  Do you remember what a machine or robot needs to work properly?

                     You have learnt about robots in the previous class. In this chapter, you will learn

                     about robots that help us every day and make our lives easier. Let’s learn about
                     robots.

                            WHAT IS A ROBOT?

                     A robot is a machine that can be programmed to do tasks on its own. Robots can

                     be small, like the ones that clean floors or very big, like the ones that build cars in
                     factories. Some robots can move, talk and solve simple problems. People create
                     robots to help with jobs that are too hard, boring or unsafe for humans.

                                       Suppose you have an AI device that could make dreams based on your wishes.
                                       What types of dreams would you choose to experience?

                                                                                                     Robot Wonders     97
