3. INTRODUTION
3
A firefighting robot is an autonomous operated machine
designed to assist in extinguishing fire and minimizing
the
risks to human firefighters. These robots are equipped
with
specialized tools, sensors and water hoses to detect and
combat fire in various environments, making them
valuable
assets in firefighting operations.

5. ARDUINO UNO
5
Arduino UNO is a microcontroller board
based on the ATmega328P. 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
6. L298N MOTOR DRIVER
6
The L298N is a popular motor driver IC
used to control the speed and direction
of DC motors and stepper motors. It's
essentially a dual H-bridge, meaning it
can independently control two motors
in both directions.
7. FLAME SENSOR
7
Flame sensors typically utilize infrared
sensors to detect the unique radiation
emitted by flames. When a flame is
present, the sensor detects the
infrared radiation and generates an
electrical signal. This signal is then
processed by the fire detection system
to trigger an alarm or activate fire
suppression measures.
8. SERVO NOTOR
8
Servo motors are used for precise
control of position, speed, and
acceleration in various applications
requiring accurate movement. They are
particularly useful in situations where
you need to rotate an object to a
specific angle or distance with great
precision.
9. MINI DC PUMP
9
A DC water pump runs on a battery,
power supply, or solar panel. These
pumps are small and easy to use. Their
primary use is to circulate, pressurize,
and emulsify liquids. They are
particularly useful in environments
where water is in short supply.
11. WORKING
11
In a Fire Fighting Robot built with Arduino and a flame sensor, the
robot autonomously detects fire and extinguishes it using a water
pump. The flame sensor is a crucial component in this system, as
it detects the presence of fire by identifying the specific
wavelength emitted by flames.
• The flame sensor is sensitive to infrared light emitted by flames.
• As the robot moves, it continuously checks the environment for any heat
signatures.
• When a flame is detected, the flame sensor sends a digital signal (either
HIGH or LOW) to the Arduino microcontroller.
• If a flame is detected, the Arduino registers the signal and processes it to
trigger the next action (navigating to the fire and activating the water pump).
12. CONCLUSION
12
Fire-fighting robot is an autonomous or remotely
controlled machine designed to assist firefighters in
extinguishing fires, performing search and rescue
operations, and navigating hazardous environments.
These robots are equipped with specialized sensors,
cameras, and firefighting tools to detect and combat fires
while keeping human firefighters out of harm’s way.
