Fire accidents cause severe damage to life, property, and the environment. This paper presents a fire detection and automatic extinguisher car system that integrates sensors, embedded control, and robotic mobility. The system detects fire using flame, smoke, and temperature sensors and autonomously navigates toward the fire source to extinguish it. Wireless communication enables real-time alerts and monitoring. Experimental evaluation shows that the proposed system achieves fast response, accurate detection, and effective fire suppression while reducing risks to human firefighters.
