Abstract

In this work, an autonomous DIY Fire-Fighting Robot is designed and implemented to detect and extinguish fires without human intervention. The system is built using an ESP-32 microcontroller integrated with infrared flame sensors, ultrasonic sensors, and a motorized platform to identify fire sources and navigate safely toward them. Upon detecting a flame, the ESP-32 processes sensor data to control movement and activates a water pump mechanism to suppress the fire. Obstacle avoidance is achieved through the use of ultrasonic sensing, ensuring collision-free operation. Experimental results demonstrate reliable flame detection, efficient navigation, and timely fire suppression in controlled indoor environments. The proposed system offers a cost-effective, scalable, and efficient solution for enhancing safety in fire-prone areas through autonomous monitoring and response.
