3. RObOT
• Robot is a system that contains sensors,
control systems, manipulators, power
supplies and software all working together
to perform a task. Designing, building,
programming and testing a robot is a
combination of physics, mechanical
engineering, electrical engineering,
structural engineering, mathematics and
computing.

4. Why fiREfighTER RObOT ?
• robots decrease the need for firefighters to get
into dangerous situations.
• the load for fire fighters reduced.
• it is impossible to extinguish fire and rescue
many victims at a time in a huge disaster.
• They may be remote control machines.
• The vehicles can reach positions that
firefighters cannot, such as petrochemical
complexes and huge warehouses fire.
• a robot can function by itself .

5. iNTROduCTiON
• This is movement based robot. It used to sense
the fire and spreads the water over that
direction.
• In this, we use RF communication to
communicate between robot and control room
that is placed in a remote place.

6. SpECifiCaTiONS
• Made from fire-resistant ceramic-fiber
compounds, silicon elastomer,polyaramid
fabric.
• Can sustain up to 138 kpa.
•
• The robot is equipped with tanks of water
and powdered fire extinguishing agents.

7. Fuel Source Class of Fire
Type of Extinguisher (Extinguishing
Agent)
Ordinary combustibles
(e.g. trash, wood, paper, cloth)
A Water; chemical foam; dry chemical
Flammable liquids
(e.g. oils, grease, tar, gasoline,
paints, thinners)
B
Carbon dioxide (CO2); halon; dry
chemical; aqueous film forming
foam (AFFF)

D
Dry powder (suitable for the specific
combustible metal involved)
Combustible Cooking
(e.g. cooking oils; animal fats,
vegetable fats)
K
Wet chemical (Potassium acetate
based)

8. hOW dOES iT WORk?
• Stays balled-up until its sensors pick up a fire
within a radius.
• Self-guided by intelligent feelers, infrared and
heat sensors.
• Has six legs to navigate itself through and
around obstacles

10. Software and Hardware
requirementS
Software Tools:
•WINAVR to compile the source file and generate
the hex code.
•ATmel to programmer the microcontroller
Hardware Tools:
•AVR(advanced virtual RISC) Microcontroller
•IR Sensor
•DC motors
•Pump

11. motor driVer
•L293D is a typical Motor driver or Motor
Driver IC which allows DC motor to drive on
either direction. L293D is a 16-pin IC which
can control a set of two DC motors
simultaneously in any direction. It means that
you can control two DC motor with a single
L293D IC.
•The L293d can drive small and quiet big
motors as well.

12. Cont.
Concept
•It works on the concept of H-bridge. H-bridge
is a circuit which allows the voltage to be
flown in either direction. As we know voltage
need to change its direction for being able to
rotate the motor in clockwise or anticlockwise
direction, hence H-bridge IC are ideal for
driving a DC motor.

13. PumP
A pump is a device that moves fluids (liquids or
gases), or sometimes slurries, by mechanical
activity. The power, P, required by the pump:
where ΔP is the change in total pressure
between the inlet and outlet (in Pa), and Q, the
fluid flowrate is given in m³/s.

14. ir SenSorS
• Infrared red(IR) light is electromagnetic
radiation with longer wavelengths than
those of visible light, extending from the
nominal red edge of the visible spectrum at
700 nanometers (nm) to 1 mm. This range
of wavelengths corresponds to a frequency
range of approximately 430 THz down to
300 GHz. Most of the thermal radiation
emitted by objects near room temperature
is infrared.
• IR sensors can measured heat and detect
motion of objects.

15. microcontroller
• The micro controller is the most important of
the design – acts as the brain for robot
• Interfaces all sensors and motors
• Contains all code for robot operations

16. effectorS
• Effectors are the means by which robots
manipulate the environment and give the
signals.
• End effector is the device at the end of a
robotic arm, designed to interact with the
environment.

17. ROBOT CONTROLLER:
• The controller is the part of the Robot which
operates the mechanical arm and maintains
contacts with its environment. This device is a
combination of hardware and software which
enable it to carry out its assigned tasks.

19. wORKING OF FIRE FIGHTING
ROBOT
• The robot along with two sensors moves in all the
directions from its mount position. When the flame or
high temperature point is detected, the Robot motion
will stop automatically and indicates fire has been
detected.
• Then the Signals from the sensors are sent to the
computer terminal and it activates the fire preventive
system.

20. ROBOT DEPLOyED IN FIRE
DEPARTMENT
•Monitor nozzle vehicle
•Reconnaissance robot
•Underwater robot
•Rescue robot

21. MONITOR NOZZLE VEHICLE
• The vehicles can reach positions that
firefighters cannot, such as petrochemical
complexes and huge warehouses fire.
• Which is used in small tunnels that
firefighters cannot enter.
• The vehicle is carried by a fire engine with a
robot controller.
• The robot moves with a double pair of
crawlers.
• Its camera turns following the monitor
nozzle.

22. RECONNAISSANCE ROBOT
• The robot is equipped with a manipulator,
two TV cameras, infrared camera, gas
detector, thermal camera.
• The manipulator has 6 degrees of freedom
and the robot moves with four crawlers
• Utilizing the manipulator and crawlers, the
robot can open doors and enter hazardous
rooms.
• The robot looks like a radio-controlled car
with a camera and detectors.

23. uNDERwATER SEARCHING ROBOT
The ole type robots are equipped only
cameras for searching new type has sonar and
thermal sensors in addition.
•The robot is used for searching victims in
fire.
•The searching area is just near coast, in port
of a big city, or in river. The water is not clear
in many cases, so the TV camera is not useful
for searching rather.
•Therefore the sonar is very necessary for the
robot.

24. Minimization of
– financial loss
–a threat to a human life
To detect the exact direction of the fire source.
• Capability of sensing accurately with increased
flexibility
• Low cost in the long run
• Reliable and economical
ADVANTAGES

25. Limitations
•Many believe it will be a better scout than
firefighter.
•Cannot leave outside for long
periods of time due to power supply.
•It is not meant to put out large fires.
•Doesn’t predict nor interfere with operator’s
thoughts.

26. appLication
•Can be used in Server rooms for immediate action in
case of fire
•Can be used in extinguishing fire where probability of
explosion is high. For e.g. Hotel kitchens, LPG/CNG gas
stores, etc.
•Every working environment requiring permanent
operator's attention. -At power plant control rooms. -At
captain bridges. -At flight control centers.

27. FUtURE scopE
• The development of sensor networks and
the maturity of robotics suggests that we
can use mobile agents for tasks that involve
perception of an external stimulus and
reacting to the stimulus, even when the
reaction involves a significant amount of
mechanical actions. However, there has
been research on many of these pieces in
different contexts, e.g., coordination among
mobile agents, techniques for detecting and
avoiding obstacles. It will be both
interesting and challenging to put all this
together into a practical, autonomous fire-
