After decades of research on robots, people feel that there is not much progress, because the application field of robots is mainly not commercial, that is, consumers often have access to knowledge, so the public feels that there is not much progress. Robots should be widely used in industrial fields. Combined with the current artificial intelligence, great progress has been made, such as construction robots, production line robots, outdoor transportation robots and so on. In the future, if robots enter the commercial market, it will give the public a brand-new look.
