This document describes the design and development of a range control fire extinguishing system in the form of a robotic system. The robotic system uses various sensors including flame sensors and ultrasonic sensors, along with an Arduino microcontroller, motor driver, water pump and other hardware to detect and extinguish fires autonomously. When a fire is detected by the flame sensors, the robotic system will navigate to the location using its motors and extinguish the fire by pumping water through its nozzle system. The system aims to provide a safer way to fight fires compared to human firefighters entering dangerous fire conditions. The document discusses the hardware and software implementation in detail and concludes the smart robotic fire extinguishing system is capable of effectively detecting and extingu
