A Self-Moving Shopping Trolley Autonomously Following Customers with Automated Billing System

A shopping center is a place where customers regularly go to purchase and pay for their items. Consequently, the number of commodities sold must be calculated to create the customer's bill. It is therefore exhausting to wait in queue for the billing of all things. Also, minor collisions often occur due to human error, while more serious accidents occur due to trolleys with loaded products, children, and other customers. The proposed solution aims to eliminate these accidents by using smart trolleys that can keep track of the customer and make the calculation for billing system. The purpose of this project is to design and build a motorized, automated shopping cart prototype that can follow customers while also having the intelligence to steer clear of obstructions. This feature has made it possible to examine how to implement the broad capability of following customers around a mall. The shopping cart in an intricate mall would be able to avoid obstacles if they were present. Besides that, through designing an automated billing system to make the customers no need to wait in line for scanning of the product items. The project is based on board technology from Arduino Uno, as well as some modules and sensors such as GSM module, RFID reader module, Ultrasonic sensor, and database that come together to form an intelligent shopping cart. The customer purchases the item and adds it to their cart. The RFID detector scans each item when it is added to the basket and updates the mall's database. With the assist of the Arduino Uno board. The final bill will appear on the cart itself when you're done purchasing through using LCD Screen and the total bill will be sent to the cashier management using GSM module. This cart does more than just minimize the requirement for human labor by moving itself. The Arduino Uno board and ultrasonic sensors that track a person through the mall enable this cart's self-moving feature. The batteries and motors that drive the shopping cart are located at the bottom of the cart.
