2.6 STEPS FOLLOWED:-a) Design power supply circuitb) Making PCB using eaglec) Mount all components and power supplyd) Check all connections and proper working of sensorse) Finish the work and interact the project with the physical world

3. WORKING

3.1 Switch on the power supply.3.2 On pressing the touch screen, input in analog form goes to microcontroller.3.3 Controller gives o/p in digital form to HT12E encoder in which address pins provide 8-bit security code for secure data transmission.3.4 Transmission becomes wireless through antenna

3.5 Receiver antenna receives the signal in address form which is decoded by HT12D decoder.3.6 Decoded signal further goes to the microcontroller mounted on mobile robot through which sensors, dc gear motor and water motor are connected.3.7 Now mobile robot will follow the instructions given by the touch screen .

4. ADVANTAGES

4.1 Replace massive human work force.4.2 Easy control over wireless link.4.3 Capability of sensing accurately with increased flexibility.4.4 Reliable and economical.4.5 No line of sight, not blocked by common materials.4.6 Extensive applications of hazardous condition.4.7 Save public property from any damages and their life.

5. FUTURE SCOPE

5.1 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”.5.2 Extended to a real fire extinguisher by replacing the water carrier by carbon dioxide Carrier.
