Fire Fighting Robotic Vehicle

http://www.edgefxkits.com/
Introduction:
 It is designed to develop a fire fighting robot using RF technology for
remote operation.
 Firefighting is the act of extinguishing fires, i.e.; it sprinkles water on
to fire.
 The robotic vehicle is loaded with the water tanker and a pump which
is controlled by wireless communication to throw water.
 An 8051 series of microcontroller used for the desired operation.
 A firefighter suppresses and extinguishes fires to prevent loss of life
and destruction of property and the environment.
Fire Fighting Robotic Vehicle

Designing the Robot:
 The robotic vehicle consists of the following units:
 A rectangular base to support the whole robot structure, attached to two
wheels for motion.
 A couple of DC motors to provide required movement to the robot.
 A control unit consisting of an RF receiver which receives command
signals from a transmitter unit to control the engine driver and control
the motors accordingly.
 A metal detector circuit along with a buzzer alarm which triggered
once the metal detected.

Working Principle of Fire Fighting Robotic Vehicle:
 The robot vehicle loaded with the water tanker.
 The pump is controlled by wireless communication (RF and Mobile
communication).
 The transmitter end connected to the push buttons.
 Using this pushbutton commands are sent to the receiver and control
moment of the robot like forward, backward, left, right.
 The receiving end three motors are connected to the microcontroller.

 In the home, offices and industries the fire sensors are kept in certain
places, when fire occurs near a fire detector.
 The RF receiver integrated with a microcontroller. When the RF
receiver receives the signals that information is passing to the
microcontroller, the robot is moved towards fire sensors.
 Once the robot reaches the desired location, then the robot stops and
activates the sprayer to that fire.
 After firing the robot, goes to the initial position.

Types of Fire Fighting Robotic Vehicles:
 Home Fire Fighting Robotic Vehicle
 Industrial Fire Fighting
 Forest Fire Fighting

Home Fire Fighting Robotic Vehicle:
 The field action constrained on the current Flore of house. This robot is
using many house hold items catch fire when someone is asleep or
away.
Industrial Fire Fighting:
 Most of the industries are faced fire accidents problems like gas, petrol,
nuclear power plants, chemical industries huge amount of damage and
more number of peoples is dead near surrounding areas.
 This robot has the strength to carry a fire around inside burning area to
supply unlimited water.

Forest Fire Fighting:
 Forest Fires is very dangers. It can be a short time burning large
amount of forest area. Even city fire departments have to deals with
forest fires in the area surrounding city.

Hardware Requirements:
 8051 SERIES MICROCONTROLLER
 PUSH BUTTONS
 RF TX-RX
 ENCODER
 DECODER
 DC MOTORS
 RELAY
 TRANSISTOR
 ROBOT BODY WITH WATER TANK
 RESISTORS
 CAPACITORS
 DIODE
 BATTERY

Software Requirements:
 Keil compiler

Advantages:
 Capability of sensing accurately with increased flexibility
 No line of sight Not blocked by common materials.
 It can pass through solids Longer range
 Not sensitive to light
 Not sensitive to weather conditions

Disadvantages:
 Communication devices mostly use similar frequency, so interference
occurs if the address are not specified.
 High cost.
 Data rate transmission is lower than wired transmission.

 It cannot be work beyond the limit

Applications:
Industries are using RF solutions:
 For monitoring, control, process, inventory tracking, data links and bar
code reading devices.
Consumer products:
 Electronic toys, home security, gate and garage door openers, intercom,
fire and safety systems, and irrigation controllers.
Medical products:
 Patient call and monitoring, handicap assistance device, surgery
communication system, remote patient data logging and ECG monitor.

Conclusions:
 This Project presents a Fire Fighting Robot Vehicle using RF
communication, and it designed and implemented MCU in embedded
system domain.
 Experimental work has been carried out carefully.
 The result shows that higher efficiency is indeed achieved using the
embedded system.
 The proposed method is verified to be great beneficial for the security
purpose and industrial purpose.

Future Scope:
 The project has been motivated by the desire to design a system that
can detect fires and take appropriate action, without any human
intervention.
 This provides us the opportunity to pass on to robots tasks that
traditionally humans had to do but were inherently life threatening.
 Fire-fighting is an obvious candidate for such automation.
 It can be enhanced by interfacing it with a wireless camera so that the
person controlling it can view the operation of the robot remotely on a
screen.
