        abstract = {The growing adoption of automation and embedded systems has significantly transformed modern retail environments by enabling intelligent solutions that enhance operational efficiency and customer convenience. Traditional shopping trolleys rely entirely on manual handling and centralized billing, which often results in physical strain, longer waiting times, and reduced shopping comfort, particularly for elderly and differently abled users. This paper presents the design and implementation of a smart shopping trolley based on the Arduino UNO microcontroller that is capable of autonomously following a customer. The proposed system integrates ultrasonic and infrared sensors to detect human presence, estimate distance, and maintain a safe following range during operation. A motor driver module is employed to control DC gear motors, allowing smooth and controlled movement of the trolley without the need for external device connectivity or complex infrastructure. Sensor data are continuously processed by the microcontroller to generate real-time control decisions, ensuring stable motion and basic obstacle avoidance. Experimental results demonstrate that the developed system effectively reduces manual effort while improving user comfort and mobility within retail spaces. Owing to its low-cost components, simple control architecture, and scalability, the proposed smart shopping trolley provides a practical and reliable solution for enhancing customer experience and supporting automation in modern retail environments.
Aim: The primary aim of this project is to design a cost-effective, Arduino UNO-based smart shopping trolley that autonomously follows customers using ultrasonic and infrared sensors. This system minimizes physical strain for elderly and differently-abled users by eliminating manual pushing, while ensuring safe navigation and reliable obstacle avoidance in retail environments.},
