This project demonstrates how to build a fire-fighting robot using Arduino. The robot is designed to autonomously detect fire (using a flame sensor) and extinguish it (using a water pump or similar mechanism). It’s a great way to learn about integrating sensors, motors, and robotics using the Arduino platform.
- 🔥 Flame Detection: The robot uses a flame sensor to detect fire sources.
- 🤖 Automatic Movement: The robot moves toward the detected fire.
- 💦 Extinguishing Mechanism: Once the fire is detected, the robot triggers a water pump to put it out.
- 🛑 Obstacle Avoidance: The robot can avoid obstacles while navigating toward the fire source.
- Arduino UNO: The main controller for the robot.
- Flame Sensor: Used to detect fire or heat sources.
- DC Motors with Motor Driver: Provides movement control.
- Water Pump or Solenoid Valve: For the extinguishing mechanism.
- Ultrasonic Sensor (optional): For obstacle detection and avoidance.
- Chassis: The physical frame for the robot.
- Power Supply: A battery pack to power the robot and components.
- Jumper Wires: For connections between components.
You can view the full circuit diagram for connecting all the components to the Arduino here.

- Connect all the components as per the circuit diagram provided in the link above.
- Make sure the flame sensor is correctly connected to the analog input pin of Arduino.
- The motors should be connected to a motor driver, and the water pump should be connected to the digital pin of the Arduino.
- Install the Arduino IDE (if not already installed).
- Open the Arduino IDE and upload the code to your Arduino board.
- Ensure that the necessary libraries (if any) are installed in your IDE.
- Power up the robot and place it in an environment with controlled fire.
- The robot should autonomously detect the fire, navigate toward it, and activate the pump to extinguish it.
- You can adjust the fire detection threshold in the code by modifying the value
500to suit your environment. - The movement and pump activation can be customized by changing the motor pins and logic in the code.
- Motor Not Running: Check the wiring and ensure the motor driver is properly powered.
- Flame Sensor Not Detecting: Make sure the sensor is placed in the right position and is facing the flame.
