Abstract: This paper presents the design and fabrication of a rocker bogie mechanism based fire fighting robot developed for rescue and firefighting operations in hazardous environments. The proposed system is capable of traversing uneven terrains, climbing obstacles, and suppressing fire using a remotely operated water spraying mechanism. The rocker bogie suspension system provides enhanced stability and mobility over rough surfaces where conventional wheeled robots face operational difficulties. The robot is powered using direct current geared motors controlled through a wireless communication system. A water pump and nozzle arrangement are integrated to extinguish fire effectively in industrial, residential, and disaster affected areas. The chassis is fabricated using mild steel and lightweight materials to achieve sufficient strength and maneuver-ability. The performance of the system is evaluated based on terrain adaptability, obstacle climb-ing capability, motor torque, and firefighting efficiency. The results indicate that the developed robot reduces human risk during firefighting operations and provides reliable movement in diffi-cult environments.
