2. ABSTRACT Automatic Fire Extinguisher Robot is a Hardware based model used to automatically extinguish the fire during fire accidents. We use Ultrasonic sensor to make our robot detect obstacles which helps it to work automatically. The fire sensor in the robot will sense the fire and starts fire extinguishing when there are fire accidents. In case of fire accidents, anyone can control the robot remotely by interfacing it to the mobile via blue-tooth module.

3. I NTRODUCTION A n a utomatic Fire Extinguisher Robot can be defined as a h ardware based model which is used to automatically extinguish the fire during fire accidents. The robot consists of Arduino uno microcontroller which acts as the heart piece of the robot.This robot also consists of ultrasonic sensor, motor driver , wheels ,bluetooth module, fire sensor and fire extinguisher. The robot can be operated automatically or remotely . User end communicates with the robot by interfacing the robot with bluetooth module. The ultrasonic sensor in the robot helps the robot work automatically. The commands are sent to the robot via bluetooth module and they are received by Arduino uno microcontroller if the robot is being controlled remotely. Whenever the fire is detected by the fire sensor ,fire extinguishing will be implemented unil the fire is completely extinguished.

5. E XISTING SYSTEM A Fire Extinguish ing Robot is a robot which can detect fire and perform fire extinguishing until there is no more fire. Previous systems were designed to detect the fire and alert people. Those robots used to alert people either by sending notifications or displaying a message on LCD or by implementing buzzer whenever the fire is detected. The existing robots do not perform fire extingushing. Previously robots were controlled manually via bluetooth module or using RF transmitters and recievers. Therefore the distance of operation was limited. And also resulted in bulky models. Less efficient microcontrollers were used in most of the existing systems.

6. PROPOSED SYSTEM This robotic vehicle has ability to substitute the fire man in case of any fire accidents . The robotic vehicle is specifically designed to identify the fire and extinguish the fire up on detection. This robot can manoeuvre automatically or can be controlled remotely by inerfacing the robot to mobile via bluetooth module. We use Ultrasonic sensor to make our robot detect obstacles which helps it to work automatically. The fire sensor in the robot will sense the fire and starts fire extinguishing when there are fire accidents. In case of fire accidents, anyone can control the robot manually by interfacing it to the mobile via blue-tooth module. This helps us to control the robot manually and perform fire extinguishing manually thereby increasing the efficiency of the robot.

8. HARDWARE COMPONENTS ARDUINO UNO Arduino uno is a micro controller board based on Atmega328. It has 14 digital input/output pins(of which 6 can be Used as PWM out puts), 6 analog inputs . Atmega328 is a 8 bit micro controller with 32KB flash memory , 2kb SRAM , 1 kb EEPROM.

9. Bluetooth HC-05 It can act as both master and slave that is can control other devices and process as master. It can also act as a slave i.e as a communication hub that is center which connects different networks. It is of 10meters range. S peed of data transfer is 3mbps.

10. FIRE SENSOR It uses infrared flame flash method and can work through a coating of oil, dust, water vapor etc Spectrum range- 760nm- 1100nm Detection range- 1 meter

11. ULTRASONIC SENSOR The Ultrasonic transmitter transmits an ultrasonic wave, this wave travels in air and when it gets objected by any material it gets reflected back toward the sensor this reflected wave is observed by the Ultrasonic receiver. Practical Measuring Distance: 2cm to 80cm Operating Frequency: 40Hz Measuring angle covered: <15°

12. L298N MOTOR DRIVER has four input and out pins has double H bridge drive chip pulling ENA & ENB high will make the motors spin pulling ENA & ENB low will stop the motors input voltage is 12V

13. SERVO MOTOR A servomotor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration. operating voltage : 5V has a highest torque limit of 4.1kg

15. SOFTWARE DESCRIPTION ARDUINO SOFTWARE (IDE) : The Arduino IDE is an open-source software, which is used to write and upload code to the Arduino boards. Here, IDE stands for Integrated Development Environment. A software driver called  boot loader  is pre-installed in the flash memory of the Atmega328 microcontroller, which makes it compatible with Arduino IDE. The program or code written in the Arduino IDE is often called as sketching. The sketch is saved with the extension '. ino .'Thus through this software we can code for the robotic movements and also for the sensors interfaced with the arduino board.

16. RESULTS Total kit gets on when power supply is given. All the LEDs represent that each device is ON and ready to perform its task.

17. f - forward movement of the robot b - backward movement of the robot l - robot turns left r - robot turns right n - nozzle of fire extinguisher gets open s - robot stops a - robot will be set to automatic m After we interface our mobile with bluetooth on robot , commands are given from an app called ‘ arduino bluetooth controller.’ The following commands make robot move in different directions.

18. If fire is detected, the fire extinguisher will move to the direction where fire is detected and extinguishes the fire. Servo motor placed under the extinguisher helps in the movement of the extinguisher. And servo motor connected to the nozzle of the extinguisher will help the robot open nozzle and perform extinguishing.

19. ADVANTAGES It is a four wheeled robot specifically designed to identify the fire and it also extinguishes the fire up on detection. This robot can maneuver automatically or can be controlled remotely. The fire sensor in the robot will sense the fire and starts fire extinguishing when there are fire accidents. In case of fire accidents, anyone can control the robot manually by interfacing it to the mobile via blue-tooth module. This helps us to control the robot manually and perform fire extinguishing manually thereby increasing the efficiency of the robot.
