Most robots are made out of metal. You can program a robot to walk and hang off of things. They can be used for many things. I think that basically anything that can move and is not human is like a robot. Some robots run on batteries or light. You have to test them to see if you programed them wrong or right. We just had a discussion about the Wizard of Oz and the Tin Man. He is made out of tin but is not a robot. What do you think? Leave your answer in the comment section below.
