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.

rObOT

• Robot exactly, 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.

HOw dOEs IT wOrk?

• Stays balled-up until its sensors pick up a fire within a half-mile radius.

• Self-guided by GPS, intelligent feelers, infrared and heat sensors.

• Has six legs to navigate itself through and around obstacles

Software and Hardware requirementS

Software Tools:•WINAVR to compile the source file and generate the hex code.•AVR Studio 4.18•AT Prog to programmer the microcontroller

Hardware Tools:•AVR Microcontroller •IR Sensor •DC motors•Pump

SpecificationS

• Made from fire-resistant ceramic-fiber compounds.

• Can stand temperatures up to 1850 ̊ F.

• The robot is equipped with tanks of water and powdered fire extinguishing agents.

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

featureS of atmel 89c51 µc

• 4k Bytes of In-System Reprogrammable Flash Memory

• 128 x 8-bit Internal RAM

• 32 Programmable I/O Lines

• Six Interrupt Sources

• On chip oscillator & clock circuitry

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.

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.

This is what Bot ,by placing sensors appropriately we can efficiently detect the location of fire.

wHere would IT Be uSeFul?

• Would be most valuable to have in small business stores, factories, or restaurants.

• Germany plans to place these bugs in campgrounds in order to prevent wildfires.

• The fire detecting Robots helps in following ways:

• 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

lImITATIoNS

•Many believe it will be a better scout than firefighter.•Cannot leave outside for long

periods of time due to battery life.•It is not meant to put out large fires.

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.

FUtURE ScopE

• As we all know that these days India is sick off massive fire tragedy, to avoid such disasters, technological power must exceed human power because “Human life and time are priceless”.

• Extended to a real fire extinguisher by replacing the water carrier by carbon dioxide Carrier.
