Human Following Smart Shopping Trolley

Helping people with physical disabilities to move independently is an important part of inclusive technology, but it is still not fully developed, especially for everyday personal use. This study focuses on a detailed design of a Smart Trolley created for users with mobility challenges, combining smart sensor-based systems and automation to reduce physical strain and improve self- reliance. The system is controlled by an Arduino Uno microcontroller, which manages signals from ultrasonic sensors, Bluetooth and IR tracking modules, and the L298N motor driver to enable semi- automatic motion. The trolley can be operated through several modes, such as voice commands, RFID tags, or a mobile application, allowing the user to move it, control its path, or let it follow automatically. Designed mainly for indoor environments like hospitals, shopping malls, and airports, it can detect and avoid obstacles for safety while staying close to the user. This paper explains the system design, working method, and expected benefits, showing how such assistive equipment can be a practical, affordable, and meaningful step toward improving independence and mobility for physically challenged people.
