🔍 Project Overview

This project is an Autonomous Fire Fighting Robot designed to automatically detect and extinguish fire in small environments such as rooms, laboratories, warehouses, and industrial areas. The system is built using an Arduino Uno, flame sensors, DC motors, a servo motor, and a water pump mechanism.

The robot continuously monitors its surroundings using multiple flame sensors placed at different directions (left, right, and forward). When fire is detected, the robot automatically moves toward the flame source and activates the extinguishing system.

A servo motor rotates the water nozzle while the pump sprays water to suppress the fire. Once the fire is extinguished, the robot stops and resumes monitoring the environment.

⚙️ How It Works (Short & Simple)

🔎 Fire Detection

Three flame sensors detect fire in different directions:

• Left sensor
• Right sensor
• Forward sensor

These sensors send signals to the Arduino Uno.

---

🤖 Robot Navigation

Two DC motors controlled through motor driver pins allow the robot to move:

• Forward
• Left
• Right
• Stop

The robot moves toward the detected flame direction.

---

🎯 Target Alignment

If the forward sensor detects fire, the robot moves straight toward the flame source.

If the left or right sensor detects fire, the robot turns in that direction.

---

💧 Fire Extinguishing System

Once the robot reaches the fire source:

• The water pump activates.
• The servo motor rotates the nozzle.
• Water is sprayed across the flame area.

This sweeping motion increases the extinguishing coverage.

---

🛑 Fire Suppression Complete

When the fire is extinguished:

• The pump turns OFF
• The servo returns to center position
• The robot stops and resumes monitoring
