Robots are the crystallization of our human wisdom and are developed and produced to serve us. There are several kinds of restaurant service robots, such as delivering food, delivering food, ordering food, welcoming guests, cooking and washing dishes. See which one you need. Take scout food delivery robot as an example. The earliest single-layer trays could only simply deliver food. Later, there was a dining car in front, which could not only deliver food, but also communicate with people, respond to physical contact and sing. Send 80 kg of vegetables at a time, at least 6 dishes, and you can bring soup and vegetables. In other words, simple, repetitive and complicated tasks can be done by robots.
