In this study, a dual operated firefighting robot was designed, fabricated and analyzed. The robot can be operated in both RC and automatic modes. The robot consists of three different types of system units- fire detection system, extinguishing system and communication system. The fire detection system uses flame sensors for detection of fire. The extinguishing unit consists of fire extinguisher cylinder mounted on the robot which can be controlled by the user through a remote. . The fire extinguisher is operated with the help of a relay circuit. The whole set up is controlled and monitored by the main controller or microprocessor. Using a belt drive enables the robot to climb stairs. The main chassis consists of 400mm*390mm aluminum profile. Four motors, each of 60 rpm, are used which provides adequate thrust for motion. The power supply for the functioning of robot is provided by a 12V, 7 AH battery. The compact design of the firefighting robot enables it to enter small or narrow space with ease. More over the dual operation ability of the robot helps to increase the overall efficiency of the robot.
