A Comprehensive Approach to Design and Implement an IoT-Enabled Intelligent Shopping Cart System with Obstacle-Aware Navigation and Enhanced Customer Engagement for Elevated Consumer Experiences

Abstract

Supermarket shopping is an experience that everyone has in life. This project aims to design an intelligent and userfriendly shopping cart and interactive web page, to elevate the overall customer shopping experience. The shopping cart designed in this project integrates multiple functionalities that allow users to access information about the items within the cart via the interactive web page and exert control over the movement of the cart. While moving, the shopping cart can autonomously detect obstacles in its path and navigate around them. Simultaneously, users can check the total cost of their selected items by reviewing the cart's contents, enabling them to decide whether the cart should continue following them. The project primarily utilizes an ultrasonic module to determine the cart's location and trail a specific customer. The shopping cart employs automatic barcode scanning to identify various products, and the WiFi module facilitates communication with the server via the MQTT protocol, enabling seamless interaction. The fruition of this project serves as a tangible representation of the Internet of Things application, demonstrating how connectivity through the internet enhances people's lives with greater convenience.
