Autonomous Fire-Extinguishing Robot for Residential Environments

This project aims to design an autonomous robot capable of detecting and extinguishing fires in residential settings upon receiving an alert from a fire alarm. The robot will utilize various cutting-edge technologies, such as infrared (IR) sensors for obstacle avoidance, temperature sensors, and fire detection capabilities. The solution integrates a retrofitted small fire extinguisher and is designed to navigate efficiently using tank treads and DC motors. The project explores multiple extinguishing methods, ensuring effectiveness for small fire scenarios.

  1. Team ί Burning Equalizer Josh Lothian Adam Stanton

  2. Problem Statement The purpose of this project is to design a robot that can autonomously locate and extinguish a randomly placed fire in a residential environment when alerted by a fire alarm.

  3. Modifying Specifications Competition Product Domestic scale Putting out small fire Extinguishing method Unconstrained • Dollhouse scale • Putting out candle • Extinguishing methods • Fan • Water jet • CO2 capsule

  4. Our Solution • Retrofit small size fire extinguisher to robot • IR sensors (for obstacle avoidance) • Tank treads • DC motors • Temperature sensor (type/model unknown at this point) • IR/UV sensors (to locate fire) • Ability to aim fire extinguisher • Microphone

  5. System Diagram Location of fire extinguisher Locations of IR sensors (top view) Design of tank treads

  6. Other Possible Solutions • Four wheels • Ultrasonic sensors (for obstacle avoidance) • Retrofit super soaker • Compressed water cannon
