The document outlines the design and implementation of a fire-fighting robot developed by students at North Western University, highlighting its motivation, components, and operational flow. The robot utilizes a flame sensor, microcontroller, and motor systems to detect and extinguish fires autonomously. Future improvements include enhancing the power source and sensor accuracy, as well as integrating a GSM module for connectivity.

3. Fire Protection system
 Industries use fire protection system
 In any critical place such as where blast will be occur human
can’t perform
 Every where human perform fire protection system.
Fire Fighting Robot
 It can perform any where.
 Lower cost robot.
 Where human can’t perform it always be.

8. Results and Discussion
P-7
When the fire causing the robot first detect and move near to
the fire. Water pump starting throw the water and servo motor
moves various angle to spare water every where.

9. Limitation
P-8
1. This system is microcontroller based and therefore must be handling with care to prevent
shifting of the microcontroller. We can add own GSM module for its built-in Wi-Fi network.
2. Its power source is battery base. So, need to develop the strong power source. Develop high
accuracy flame sensor.
3. Sensor range is too short so, need to include high range sensor.

10. Future Work
P-8
1. Replacing the fan by a carbon-di-oxide carrier
2. We can add own GSM module for its built-in wifi network
3. Design its own large power supply unit
4. Develop high accuracy flame sensor

11. Conclusion
1. Here we successfully developed the Fire Extinguisher Robot.
2. Robot detects temperature, smoke and flame at the site where the robot exists.
3. The movement of this robot vehicles is controlled by MCU as per the program..
4. The proposed method is verified to be great beneficial for the security and industrial
purpose.
