Automated Cafeteria System for Efficient Food Serving

The restaurant is now gaining more importance in terms of automation. The usual procedure used for food ordering in restaurants is a manual process. It involves the waiters noting down the menu from customers, transferring the orders to the kitchen, serving the menu and finally preparing bills. This process even though looks simple, is prone to human errors while note making and delays involved. So the customers end-up with unsatisfactory service. Considering this fact and with an aim to improve efficiency and reduce errors in conventional food ordering system, new technology is introduced to automate the process. The ordering process is made simple through which the customer can order the food item from the table itself. It consists of Mobile App and LCD display to order the food item and to display the ordered food item to the customer respectively. The ordered food item will be transferred to the kitchen using the Bluetooth Module. The serving process consists of food serving conveyer belt which is used to serve the foods to the customer depending upon their order. The conveyer belt uses arduino microcontroller for programming. The cost of the ordered food item will get added up and the total bill amount will be shown to the customer and it will be sent to the billing counter. Website will also be created for the restaurant.
