I would like to have a smart robot that can do plenty of the things for me. For example, it can clean my room and make the bed, keeps everything in order. I hope it will be programmed to do homeworks without making mistakes. In that way, I can turn to it wherever I need help with my study. Beside, it can take care of my little brother, who often bothered me much. Then I can have more free time to do what I'm fond. It doesn't matter much whether it is shaped like, but it must be able to communicate with me and understand its feelings. How wonderfully life will become with such a magic robot!
