AUTONOMOUS PERSON TRACKING ROBOTIC CART

Abstract

This project focuses on the development of an Autonomous person-tracking robot using embedded electronics and sensorbased navigation. The robot is built around an Arduino Uno microcontroller, which acts as the main controller to process sensor data and control the motors. The system uses an ultrasonic sensor to detect and track a person by maintaining a safe following distance in indoor environments without manual control. IR sensors are mounted on the front and sides of the robot to detect obstacles and prevent collisions, ensuring safe navigation. When an obstacle is detected, the robot either stops or changes its direction accordingly. A 16×2 LCD display is used to show real-time information such as robot movement status and obstacle detection details and tracking updates. The L293D motor driver interfaces the Arduino with DC motors, enabling forward, backward, and turning motions based on the signals from the Bluetooth module and obstacle sensors. The system is designed to maintain a safe following distance, respond dynamically to changes in the environment, and provide immediate feedback to the user. This low-cost, scalable, and reliable robotic cart has potential applications in smart shopping carts, indoor delivery systems, hospitals for transporting supplies, and personal assistance for the elderly or physically challenged individuals
