Abstract: A fire fighter run into risky situations while extinguishing fire and rescuing victims. In contrast, a robot can function automatically or can be controlled from a distance, so that firefighting and rescuing activity could be executed by using a robot instead of putting fire fighters at risk. This robot uses gear motors, microcontroller, sensors, RF controller and an extinguisher. Microcontroller acts as the brain of the robot. Fire Fighting Robot continuously monitors the temperature of four temperature sensors fixed at four sides of the robot and if presence of fire is found to be true, the robot moves in the direction to which the temperature is relatively high among the four sensors and puts down the fire with the extinguisher. As the fire sensors sense the fire, it sends signal to the microcontroller via a comparator circuit. As soon as microcontroller receives the signal an alarm sounds. Also a predetermined message will be sent to the fire station using GSM modem. After sounding the alarm microcontroller drives the robot towards fire place. As the robot reaches near the fire source, the extinguisher is turned on and the fire is extinguished. Also any obstacle in its path can be detected by means of an ultrasonic wall detector. If the robot gets blocked or trapped in any situations inside a room, the robot can be externally controlled by using an RF controller from outside.
