Title: Servingbot operating system combining CCTV footage
Inventor: LEE KI HYUN
IPC: G06Q20/18
Filed: 2020-08-20
Abstract: The present invention provides an unmanned food ordering and distributing system using CCTVs, installed in most stores, in a serving bot operating system. When an unmanned ordering machine show menus to a customer, the customer selects one of the menus. The selected menu is transmitted to a terminal (for example, a tablet personal computer) provided in the kitchen, and an order number and the menu are recorded thereon. At the same time, the order number and the menu are recorded on a serving bot terminal. When the customer who has placed the order goes to an empty table and sits down, CCTVs in a store track the movement of the customer and recognize the identification number of the table through image analysis or character recognition on the identification number of the table on the table, and send a corresponding table number to the terminal in the kitchen. The identification number is written in the order number previously assigned to the terminal in the kitchen and the serving bot terminal. When cooking is complete, if the customer operates a complete button on the order number on the terminal in the kitchen, the serving bot moves to the kitchen. When the order number, menu, and table number displayed on the serving bot terminal are checked in the kitchen and food is loaded thereonto, the serving bot moves to the table and distributes the food. Therefore, the unmanned food ordering and dispensing system can further strengthen unmanned food ordering and distribution using the serving bot.
