This document describes the design of a firefighting robot. The robot uses an RF transmitter and receiver to control a microcontroller that operates motors, sensors and a water pump. It aims to extinguish fires autonomously. The key components are an 8051 microcontroller, IR sensors to detect heat, a motor driver to control movement, and a water pump for fire suppression. The robot's design allows it to locate and douse fires remotely without endangering human firefighters.
