Smart Line Follower Robot Using IoT System

Abstract

This project presents the design and development of a smart line follower robot using IoT system. The robot is capable of autonomously following a predefined path using infrared (IR) sensors, ensuring accurate navigation without human intervention. In addition to line-following functionality, the system enhances security by incorporating a theft detection mechanism. The theft detection module uses sensors such as motion sensors or IR interruption sensors to detect unauthorized access or disturbances. When a theft attempt is detected, a buzzer is activated to provide an immediate local alert. Simultaneously, the system sends realtime alert messages to the user via Telegram, ensuring instant notification regardless of location. To further enhance monitoring, the project includes a live video streaming feature, allowing users to visually monitor the environment in real-time through an IoT platform. This enables better surveillance and quick decision-making during security breaches. The system operates without traditional remote control, relying entirely on autonomous behaviors and IoTbased communication for monitoring and alerts. The main components used in this project include a microcontroller (such as Arduino or Node MCU/ESP8266), IR sensors for line detection, motion or proximity sensors for theft detection, a buzzer for alerts, a camera module for live streaming, motor drivers, and DC motors for robot movement. The integration of these components creates a cost-effective and efficient smart robotic system suitable for industrial automation and security applications. Overall, this project demonstrates the effective combination of robotics and IoT technologies to achieve autonomous navigation, realtime monitoring, and enhanced security without the need for manual remote operation.
