Firefighting robot

Abstract

The goal here is to design and construct the prototype of a remotely controlled robot capable of extinguishing the fire. The robot consists of DC motors to facilitate the movement of the robot. Two types of extinguishing actions have been employed here. It incorporates a water pump to extinguish the fire. The water pump is immersed in a water tank that is on board. Another type of extinguisher contains a DC motor that actuates a water spray. This is used to mimic a traditional carbon dioxide-based fire extinguisher. The robot can be controlled using radio frequency transmitter. Based on which key is pressed the encode ion the transmitter sends a command to the receiver. The receiver has a decoder with it, which decodes the command and initiates the action to be taken, like rotating the DC motor in a particular direction. The robot works on direct current supplied via a switched mode power supply (SMPS).
