This document describes a wireless firefighting robot controlled by a touchscreen. The robot is divided into two parts: a control panel with a touchscreen and microcontroller, and a mobile robot with microcontroller, sensors, motor and water sprayer. The touchscreen sends commands wirelessly to the mobile robot to navigate and spray water when the fire or obstacle sensors detect issues. This robot aims to reduce risks to human firefighters and control fires remotely. Its advantages include replacing human labor, easy wireless control, accurate sensing and reliability. The technology has potential for hazardous applications and preventing future fire disasters.

12. 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

13. WORKING contd…..

14. WORKING Contd…..
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 .

15. WORKING Contd…..
3.8 As sensors detect the fire or obstacle ,
there will be voltage drop identify by the
microcontroller.
3.9 microcontroller then transmits the signal
to the water motor and water will
sprinkled over the detected fire .

18. 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.
