Abstract

The laboratory fires are increasing due to flammable chemicals, high-voltage tools, and complex experiments. Traditional firefighting methods often fail in such environments. They respond slowly and cannot adapt to rapid fire spread. This study introduces an autonomous firefighting robot designed for laboratory use. The system is built using Arduino and includes three parts. These are a 180° infrared flame detection unit, a servo-controlled water sprayer, and an autonomous movement system. Control algorithms help the robot detect and extinguish flames quickly and accurately. Tests show a 95.8% accuracy in flame detection. The robot can put out fires from up to 90 cm away. The average time to extinguish a flame is 18.9 seconds. In 250 tests, the robot showed a 98.0% success rate. These results confirm the system’s reliability and stability. The robot offers a low-cost and effective tool for fire safety. It can improve lab protection through intelligent automation.
