It feels great to go to a restaurant and see a high-tech thing, that is, a food delivery robot. Can someone explain how it works?

Nowadays, some fashionable or bigger restaurants use food delivery robots. I am a robot, so 37.com can answer you. Nowadays, most of the food delivery robots are realized by orbital operation (the price of orbital food delivery robots in the mass market is acceptable at present) and computer-side software control. In fact, the robot itself is a computer operating system. Set the IP (some don't need to be set), connect the robot WIFI through routing, open the software on the computer to set up the robot, and then run it. As for some functions of robots, you must have seen them in restaurants.
