  What is a Fire Fighting Robot? A fire fighting robot is an autonomous or remotely operated machine designed to detect and extinguish fires without human assistance. These robots are equipped with sensors to identify flames or smoke and use extinguishing agents such as water, CO₂, or other fire suppressants to control and put out the fire. Powered by a microcontroller, advanced models can automatically locate the fire, navigate toward it, and efficiently extinguish it. In this project, we’ll learn how to create a DIY Arduino-based Fire Fighting Robot . This robot will use flame sensors to detect fire, BO motors with a motor driver to move toward the fire, and a mini water pump to spray water and extinguish it. Materials Required Arduino UNO Flame Sensors (3 units) Servo Motor (SG90) L293D Motor Driver Module Mini DC Submersible Pump Small Breadboard Robot Chassis with 2 motors and 2 wheels Small Water Can (for the water tank) Connecting Wires...
