Hardware based Automatic Fire Extinguisher Robot

A Robot suitable for automatically extinguishing the fire during fire accidents is presented in this paper. The Robot moves in the direction with respect to the fire intensity and avoids self-destruction using calcium silicate boards shielded with, that are capable of withstanding very high temperatures. The principle used, was designed and experimented at a temperature of 300°C. The temperature sensing capability of the robot is varied by heating the Thermocouple ends to a cut-off temperature, above which the robot starts responding to the fire. The Robot finds its applications in Rescue operations during fire accidents, in closed loops such as hospitals and shopping malls, where the possibility for service men to enter the fire prone areas is very less and also during wars to perform rescue functions. The most added advantage of this Robot is that it turns ON automatically as it detects the fire within a distance of 5-10cms, using Thermocouple, and tries to extinguish it by moving in the direction with respect to the fire intensity. The temperature sensor provides a backup to the Thermocouple, if needed in vast circumstances.
