On January 5th, students in our school visited Robot World, which we saw a great diversity of robot. It was amazed to find those robots could do a great number of things just like real people, including playing chess, playing piano and drawing pictures. What’s more, the robots were in different kinds and shapes, which made us enjoyable. In addition, that excited me most was the show given by a group of robots. They danced just as if they are dancers on the stage. By visiting Robot World, I have learned a lot of about robots , especial about their functions and shapes. The great human wisdom is so powerful that it make us feel more comfortable live in the world.
