The document describes a smart firefighting robot that uses IoT technology. The robot can detect fires automatically using sensors, stream video of the fire site to authorities, and spray water from hoses to extinguish the fire. It is designed to reduce risks to human firefighters by allowing remote or autonomous control. The robot uses components like an ESP32 camera, fire sensor, motor driver, water pump and Arduino board to carry out its functions.

3. Introduction
The IoT fire-fighter robot helps to extinguish fire efficiently.
The robot is in the environment where the fire occurs and it
is connected to the authority. Authority is some people who
are monitoring the environment. All these are connected
through Internet of Things (IoT). IoT is the interconnection
of objects via Internet and enabling them for communicate
each other [1]. Here IoT enables better communication
between robot and authority. Authority can view the
environment through the robot and they can take
appropriate action for extinguishing the fire

4. Motivation
 Fire fighters face risky situations when extinguishing fires
and rescuing victims, it is an inevitable part of being a
fire fighter.
 In contrast, a robot can function by itself or be controlled
from a distance, which means that fire fighting and
rescue activities could be executed without putting fire
fighters at risk by using robot technology instead.
 In other words, robots decrease the need for fire fighters
to get into dangerous situations.

5. Objective
To detect the fire automatically.
To spray water in fire until the fire off.
To live stream the fire condition in mobile or pc.
To spray water and detect fire from multiple side.
To carry water with robot.

6. Methodology
The construction of robot is designed such that the Fire
detection and automatic Water spray in fire using two
hose pipe.
The robot detect the fire automatically.
After that by its own the robot able be spray water in fire.
Control the robot using mobile
A Camera is for streaming the condition of fire.

8. ESP32-CAM is a low-cost ESP32-based
development board with onboard camera,
small in size. It is an ideal solution for IoT
application, prototypes constructions and DIY
projects. The board integrates WiFi, traditional
Bluetooth and low power BLE , with 2 high-
performance 32-bit LX6 CPUs.

9. The flame sensor of a furnace is a safety device
that detects whether the equipment is producing a
flame and burning gas. Located in front of the
burners, it's a rod that juts out where the flame
comes out of the burner. It's always on the
opposite side of the ignitor as well.
The L298N is a dual H-Bridge motor driver
which allows speed and direction control of two
DC motors at the same time. The module can
drive DC motors that have voltages between 5
and 35V, with a peak current up to 2A.

10. Servo motors or “servos”, as they are known,
are electronic devices and rotary or linear
actuators that rotate and push parts of a
machine with precision. Servos are mainly used
on angular or linear position and for specific
velocity, and acceleration.
The Arduino Nano is a small, complete, and
breadboard-friendly board based on the ATmega328
(Arduino Nano 3.x). It has more or less the same
functionality of the Arduino Duemilanove, but in a
different package. It lacks only a DC power jack,
and works with a Mini-B USB cable instead of a
standard one.

18. Conclusion
Nowadays, the concept of fire-fighter robot is very common. But this
IoT fire-fighter robot solves some issues in the existing fire-fighter
robots. They are both autonomous and controlled. It has a
monitoring system to know the fire and people who stuck in the
environment. Also the monitoring system can be implemented as an
Android application. The robot helps other fire-fighter men by giving
them a safer path to fire. Because lots of fire-fighter men have lost
their life while saving other’s life. Using the robotic arm in the robot,
it can pick up the people who stuck in there for help. This IoT fire-
fighter robot can be implemented as in the form of drone. Using the
application of artificial intelligence, the robot can be trained to find
fire type and to choose appropriate extinguishing methods. For
some large fires like forest fire, the extended version of this robot
helps to extinguish the fire in a large amount. So, nowadays the
relevance of this robot is increasing.
