It was five feet 129 and had a big face. It was easy for me to use it. With the help of the robot, I could have lessons just like my classmates. I could also take a photo of my 130 and give it to the teacher. What’s more, my classmates could talk to me easily. After a few days, my robot became 131 at school. Everyone wanted to talk to me or ask me some questions on my 132 . I could do many things just like any other student.
