Firefighting Robot with Flame and Gas Detection

Fire hazards pose a serious risk to life, property, and the environment, particularly in industrial, residential, and laboratory settings. Traditional firefighting methods often endanger human personnel due to exposure to extreme heat, toxic gases, and unstable conditions. This project presents the design and development of a Firefighting Robot with Flame and Gas Detection, aimed at improving fire safety through automated hazard detection and suppression. The system integrates an Arduino Uno microcontroller with flame and gas sensors (MQ-2) for real-time monitoring, a Bluetooth module (HC-05) for wireless control, and a servo-driven water pump for targeted fire extinguishing. The three-wheeled chassis, powered by DC motors and controlled via a motor driver (L298N), ensures mobility in confined spaces. Upon detecting flames or hazardous gases, the robot activates a buzzer to alert the operator and initiates the suppression mechanism. The modular design allows for scalability and potential integration of autonomous navigation and advanced imaging systems in future iterations. This work demonstrates a compact, cost-effective, and efficient firefighting solution that minimizes human risk while ensuring rapid and precise fire response in hazardous environments.
