Fire Fighting Robot

Autonomous fire-response robot that detects flame direction and activates a water pump.

Overview

This mobile robot detects a flame source, moves toward it, and activates a small water pump or extinguisher mechanism. It demonstrates sensor-based navigation, fire detection, motor control, and emergency-response automation in a compact robotics build.

Implementation details

Firmware

Firmware reads flame sensor direction, drives the robot toward the source, stops within range, and activates the pump output.

Power

Battery supply powers motors and pump separately from logic to reduce voltage dips.

Components / BOM

Arduino UNO, Flame sensor array, Motor driver, Water pump, Battery pack

Engineering challenges

False triggering, pump power draw, and motor control near the flame source were the main issues.

Solutions

Used directional flame sensing and separate pump/motor control stages.

Results & metrics

Demo prototype shows detection and extinguishing workflow.

Future improvements

Add thermal sensing, better nozzle targeting, obstacle avoidance, and fireproof mechanical design.
