  AUTONOMOUS FIRE EXTINGUISHROBOT
• 2.
  Abstract • The principlesused in this design are such that enable our robot to be extended to a more robust system to be used to combat actual fires in residential or commercial settings. • The main requirement of this project is to create a robot that is fully autonomous. • This means that once the robot is started by the user, it navigates, searches for, and extinguishes the fire on its own, with no assistance or input from the user.
• 3.
  • In orderto reach this goal, we made many critical decisions on motors, sensors, fire extinguishing mechanical parts and general design for our robot. • Lastly, we wanted our robot to not only accomplish these requirements, but also be able to do so quickly and accurately.

  Literature Survey • Arduino:Arduinois a hardware and software company that designs and manufactures single board microcontrollers. • The Arduino language is merely a set of C/C++ functions that can be called from your code. • The microcontroller used is ATmega328. • It has 14 digital input/output pins (of which 6 can be used as PWM outputs),6 analog inputs,a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button.

  • L293D motordriver IC:A motor driver is an integrated circuit chip which is usually used to control motors in autonomous robots. Motor driver act as an interface between Arduino and the motors. These ICs are designed to control 2 DC motors simultaneously.
• 8.
  • Servo motor(SG90):ServoMotors are used in applications where very high precision motion is required like assembly robots, computer numeric controls etc. • Servo can rotate approximately 180 degrees. (90 in each direction)
• 9.
  • IR Firesensors:These types of sensors are used for short range fire detection and can be used to monitor projects or as a safety precaution to cut devices off / on. • This unit is mostly accurate up to about 3 feet. • The sensor basically detects IR (Infra Red) light wavelength between 760 nm – 1100 nm (nano meter) that is emitted from fire flame.
• 10.
  Working • The mainbrain of this project is the Arduino, but in-order to sense fire we use the Fire sensor module (flame sensor). • When fire burns it emits a small amount of Infra-red light, this light will be received by the IR receiver on the sensor module. • So, we place three such sensors in three directions of the robot to sense on which direction the fire is burning.
• 12.
  • We detectthe direction of the fire we can use the motors to move near the fire by driving our motors through the L293D module. • When near a fire we have to put it out using water. • Using a small container we can carry water, a 5V pump is also placed in the container and the whole container is placed on top of a servo motor so that we can control the direction in which the water has to be sprayed.

  Conclusion In this projectwe aim to reduce the effect of fires accidents which usually start from small flame, therefore people life and money would be saved. The robot can successfully find fire and reach it without running into obstacle.
