The main aim of this project is to build a firefighting robot. The Robot can be moved in all the four directions (front, back, left and right). The robot is designed in such a way that there is no requirement of manual attention towards it. This project makes use of four fire sensors which we place the four sides of the robot to detect the fire. Water motor long with relay is uses to spray the water if the sensor detects the fire. Here relay works as a switch to ON/OFF the water motor. DC motors long with l293d motor is uses to moves the robot. The Arduino Uno is a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which 6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB connection, a power jack, an ICSP header, and a reset button. It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable or power it with an AC-to-DC adapter or battery to get started. The controlling device of the robot system is Arduino UNO Microcontroller. Microcontroller reads the data from fire sensors and decides the direction and operates the DC motors connected to it accordingly. The system also controls the fire extinguisher when the fire was detected, this robot will move towards the fire and spray the water to stop the fire. To perform this intelligent task, Microcontroller is loaded with a program written in embedded ‘C’ language.
