1. INTRODUCTION

   Fire is one of the most dangerous and destructive hazards, causing significant loss of life, property, and environmental damage. In industrial, residential, and commercial environments, fire accidents can spread rapidly due to flammable materials, electrical faults, and human negligence. Conventional firefighting methods require direct human involvement, which exposes firefighters to high temperatures, toxic gases, and life-threatening conditions. Therefore, there is a growing need for intelligent and automated systems that can reduce human risk and improve fire response efficiency. Recent advancements in robotics and embedded systems have led to the development of autonomous fire-fighting robots capable of detecting and extinguishing fire without human intervention. Many existing systems use microcontrollers, flame sensors, and water-based suppression mechanisms. However, most of these systems rely on conventional power sources, limiting their sustainability and operational time.

   To address these limitations, this paper presents the design and development of a solar-powered automatic firefighting robot. The proposed system integrates an Arduino Nano microcontroller with flame sensors for fire detection and an ultrasonic sensor for obstacle avoidance. A solar energy system consisting of a solar panel, charge controller, and battery ensures continuous and eco- friendly operation. The robot autonomously detects fire, navigates toward it, and activates a water pump to extinguish it.This work aims to provide a cost-effective, energy-efficient, and reliable solution for small-scale fire safety applications such as homes, laboratories, and industrial environments.
