Intelligent robots, as a technology containing considerable multi-disciplinary knowledge, are almost accompanied by artificial intelligence. Intelligent robots are becoming more and more important in today\'s society. More and more fields and positions require intelligent robots to participate, which makes the research of intelligent robots more and more frequent. Although it is still difficult for us to see the shadow of intelligent robots in our lives. But in the near future, with the continuous development and maturity of intelligent robot technology. With the unremitting efforts of many scientific researchers, intelligent robots will surely enter thousands of households. Better serve people\'s lives and make people\'s lives more comfortable and healthy.
