An autonomous fire-fighting robot built using Arduino Uno, designed to detect and extinguish fires with minimal human intervention. Developed as part of the CSE461: Introduction to Robotics course project at BRAC University, Spring 2024.
This project explores the integration of robotics in emergency response systems, focusing on fire safety. The robot uses multiple flame sensors to detect fires and then navigates towards the fire to extinguish it using a water pump, guided by a servo-controlled nozzle. The entire system is built on the Arduino Uno microcontroller platform and mounted on a 4WD chassis.

- L298N Dual H-Bridge Motor Driver
- Servo Motor (SG90)
- Submersible Mini DC Water Pump (3V)
- 9V Battery & Holder
- Breadboard and Jumper Wires
- Passive Buzzer
- Detection: Flame sensors identify fire and determine its direction (left, right, forward).
- Navigation: Based on sensor input, motors are controlled to navigate toward the fire.
- Extinguishing: Once near the fire, the water pump activates, and the servo motor sweeps the nozzle to distribute water effectively.
- Feedback: A buzzer sounds as an alert mechanism during operation.
Initial Setup:
- Fully charge the battery.
- Fill the water reservoir.
- Place the robot at a strategic starting point.
Operation:
- Robot actively scans for fire using flame sensors.
- Upon detection, it navigates and extinguishes the fire autonomously.
Maintenance Tips:
- Clean sensors and chassis regularly.
- Check battery level and water reservoir.
- Store in a cool, dry place when not in use.
Safety Precautions:
- Prevent water contact with the electronics.
- Supervise during operation.
