This paper presents the design and development of an autonomous fire-fighting robot equipped with flame detection, obstacle avoidance, and fire extinguishing capabilities. Presently, the fire-fighting robots are operated by humans without complete automation. The robot employs flame sensors to detect fire in multiple directions and ultrasonic sensors to navigate obstacles. It utilizes servomotors to control a water-spraying nozzle for extinguishing fire in a predefined smooth motion. A track-belt drive system provides mobility for operation in diverse terrains. The robot is powered by an Arduino Uno microcontroller, with modular components such as a water pump, DC motors, and sensors for efficient functionality. Experimental results demonstrate the robot’s ability to autonomously detect fire, navigate toward it, and extinguish it, making it a viable solution for fire suppression in hazardous environments.
