This advanced project allows a user to control a fire fighter robot equipped with water tank and gun remotely wirelessly for extinguishing fires. For this purpose, the system uses an RF remote for remote operation along with RF receive based Microcontroller circuit for operating the robotic vehicle and water pump. The RF based remote transfers users’ commands through RF signals which are received by the receiver circuit. The receiver circuit now decodes the data commands sent. It then forwards it to the Microcontroller. Now the Microcontroller processes these instructions and then instructions the vehicle motors to run the vehicle in desired directions. It also operates the water pump motor and pump direction motor to spray water based on users’ commands. This allows the user to operate the robot and put off the fire by standing at a safe distance. The robot operates within an 8-meter range of the remote.

3. ABSTRACT
 Determining and extinguishing the fire is a dangerous job for a fire extinguisher.
 To this problem the fire fighter reaches the destination quickly and prevent the fire.
 Due to this fire fighter are constantly at a risk of losing their life.
 Technologies has come to rescue this issue. This paper proposes the technical
solution to this mentioned problem.
 These robots are designed to use in extreme condition whereas humans’
interruption becomes less and robots are using several works.

4. OBJECTIVE
The goal of the fire-fighting robot is to create a wheeled
robot with capabilities to navigate through a specially
designed maze, detect a candle flame (simulating a fire),
extinguish the flame, and return to a designated location
within the maze.

5. INTRODUCTION
 Robotics is one of the fastest growing engineering field of today’s era.
 Robots are designed to remove the humans factor for dangerous work and also for
difficult environment.
 The use of robot is more widely used than ever before.
 The need of fire extinguisher robot is that can detect and extinguish the fire at its
own risk.
 Our aim as a engineers is to design such a device which can automatically detect
and extinguish the fire also aims to reduce the air pollution.
 This robot is design as a wireless controlled operated robot.
 It is a protocol which can move through a model structure, find a fire and extinguish
with the help of the water jet.

S.NO AUTHORS DESCRIPTION
1
• Tawfiqur Rakib
• M. A. Rashid Sarkar
Proposed a fire fighting robot model which consists of a
base platform made up of ‘Kerosene wood’, LM35 sensor for
temperature detection, flame sensors to detect the fire and
a water container of 1 litre capacity which is made up of a
strong cardboard that makes it water resistant. The robot
has two wheels for its movement.

• Nagesh MS,
• Deepika T V
• Stafford Michahial
• Dr M Shivakumar
Proposed a fire extinguishing robot which employs DTMF
(Dual Tone Multi Frequency Tones) technology for the
navigation of the robot and uses a flame sensor for fire
detection that is capable of sensing flame of the wavelength
range 760 to 1100 nm and sensitivity varies from 10cm to
1.5feet.

7. EXISTING SYSTEM
 There are two DC motors used for motions.
 There are the heat sensors used Temperature for
detecting the increase in fire for detection of fire.
 12 V Battery Used.
 DC water pump is used to pump water for
extinguishing the fire.

8. PROPOSED SYSTEM
 This project is the ATMEL, but in-order to sense fire we use the Heat sensors.
 These sensors are used to detect the fire. When fire burns it emits a small amount
of Infra-red light, this light is received by the LDR on the sensor module.
 We will detect the direction of the fire we can use the motors to move near the fire
by driving 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 and a 5V pump is placed in the container
and is placed on top of a servo motor so that we can control the direction in which
the water has to be sprayed.

10. ATMEL MICROCONTROLLER
The AT89S52 is a low-power, high-performance
CMOS 8-bit microcontroller with 8K bytes of in-
system programmable Flash memory.
The device is manufactured using Atmel's high-
density nonvolatile memory technology and is
compatible with the industry-standard 80C51
instruction set and pinout.

11. L293D MOTOR Driver
The L293 and L293D devices are quadruple
high-current half-H drivers. The L293 is
designed to provide bidirectional drive
currents of up to 1 A at voltages from 4.5 V to
36 V. The L293D is designed to provide
bidirectional drive currents of up to 600-mA at
voltages from 4.5 V to 36 V.

12. RELAY
A relay is an electrically operated switch
that harnesses the power of an
electromagnet to either open or close a
circuit, while a switch is a mechanical
device that opens or closes a circuit
physically. Switches can be activated
manually, but relays are typically controlled
by electrical signals.

13. BLUETOOTH MODULE HC-05
The HC05 Bluetooth module is used as
UART serial converter module and can
easily transfer the UART data through the
wireless Bluetooth.
The Bluetooth module has a
Frequency: 2.4GHz ISM band, PIO control
and comes with an integrated antenna
and edge connector.
