This document describes a smart luggage carrying robot that uses a Raspberry Pi. The robot is designed to help customers at supermarkets and hypermarkets by allowing them to scan items as they shop to avoid long checkout lines. It uses a camera and Raspberry Pi to identify when a customer's membership card is inserted, allowing the cart to function as a smart cart for scanning items. The robot then follows the customer around the store as they shop. When done, it provides a total for their purchases to avoid waiting at the checkout. The document discusses the hardware and software used to create this smart luggage carrying robot.
