Autonomous Food Ordering System in for Food Court

Concept

Customers at a food court use kiosks or mobile devices to browse menus of multiple restaurants. They can order food from different restaurants and specify whether they will dine in or pick up their orders. Once the food is ready, automated delivery robots (or a notification system) can bring the food to the customer's table or notify them to pick it up. Payment can be done upfront or after all food has been delivered.

Core Components

1. Orders Service

Manages food orders placed by customers.

Restaurants Service

Handles restaurant information, including menus and availability.

Payments Service

Manages customer payments and financial transactions.

Delivery Service

Coordinates the robot (or a notification) to deliver food to the customer.

Communication Architecture

• Use event-driven architecture to notify services about the state of food orders (e.g., when orders are placed, when food is ready).
• gRPC APIs to communicate between services.
• Notifications are sent to the customer when their food is ready for pickup or when it's on its way.

Optional Enhancements

• Add real-time tracking of robots delivering food.
• Provide an estimated wait time for food to customers.
• Implement loyalty programs where returning customers can receive discounts or offers.

This system would leverage event-driven architecture to ensure efficient communication between services, much like in the tutorial you're following.
