Acknowledgement

We would like to express our sincere gratitude to our veteran mentor Mr. Natraj Mishra (Assistant Professor, Mechanical Department), for giving us this opportunity to work on the project Fire Fighting Robot Remotely Operated. Thanks are due to our university- University of Petroleum & Energy Studies for introducing the major project in our course curriculum. Also we would like to thank the university for believing in us that we can complete this project successfully. Thanks are due to our Dean- Dr. Kamal Bansal for providing the students this platform to present such reports while pursuing their graduation. We would like to extend our thanks to all the faculty members of the Mechanical Department who have helped us in some or the other way in making our project. Thanks are due to all our classmates, our parents and our colleagues without whom the making of this project was not possible. At last thanks are due for the researchers whose paper gave us the right direction to work.

Abstract

The project is designed to develop a fire fighting robot using RF technology for remote operation. The robotic vehicle is loaded with water tanker and a pump which is controlled over wireless communication to throw water. An 8051 series of microcontroller is used for the desired operation.At the transmitting end using push buttons, commands are sent to the receiver to control the movement of the robot either to move forward, backward and left or right etc. At the receiving end three motors are interfaced to the microcontroller where two of them are used for the movement of the vehicle and the remaining one to position the arm of the robot. The RF transmitter acts as a RF remote control that has the advantage of adequate range (up to 200 meters) with proper antenna, while the receiver decodes before feeding it to another microcontroller to drive DC motors via motor driver IC for necessary work. A water tank along with water pump is mounted on the robot body and its operation is carried out from the microcontroller output through appropriate signal from the transmitting end. The whole operation is controlled by an 8051 series microcontroller. A motor driver IC is interfaced to the microcontroller through which the controller drives the motors. Further the project can be enhanced by interfacing it with a wireless camera so that the person controlling it can view operation of the robot remotely on a screen.

Need of the Project

Cultural property management is entrusted with the responsibility of protecting and preserving an institution's buildings, collections, operations and occupants. Constant attention is required to minimize adverse impact due to climate, pollution, theft, vandalism, insects, mold and fire. Because of the speed and totality of the destructive forces of fire, it constitutes one of the more serious threats. Vandalized or environmentally damaged structures can be repaired and stolen objects recovered. Items destroyed by fire, however, are gone forever. An uncontrolled fire can obliterate an entire room's contents within a few minutes and completely burn out a building in a couple hours. Hence it has become very necessary to control and cease the fire to protect the Life and costlier things. For that purpose we planned to design and fabricate the fire-fighting robot.

Autonomous robots can act on their own, independent of any controller. The basic idea is to program the robot to respond a certain way to outside stimuli. The very simple bump-and-go robot is a good illustration of how this works.

This sort of robot has a bumper sensor to detect obstacles. When you turn the robot on, it zips along in a straight line. When it finally hits an obstacle, the impact pushes in its bumper sensor. The robot's programming tells it to back up, turn to the right and move forward again, in response to every bump. In this way, the robot changes direction any time it encounters an obstacle. Advanced robots use more elaborate versions of this same idea. Roboticists create new programs and sensor systems to make robots smarter and more perceptive. Today, robots can effectively navigate a variety of environments.

Statement of the Project:-

The project is designed to develop a fire fighting robot using RF module for remote operation. The robotic vehicle is loaded with water tanker and a pump which is controlled over wireless communication to throw water. At the transmitting end using RF module, commands are sent to the receiver to control the movement. When the robot faces a fire then it extinguishes fire with the help of pump motor connected to a water tank mounted on its body. Remote operation is achieved by Radio Frequency technology. The RF transmitter acts as a remote control that has the advantage of adequate range.

The main objectives of the project Construction of RF based intelligent fire extinguisher vehicle system. Water Flow through wireless RF technology. Movement of the Robot in all directions. The project provides the following learnings: Wireless Radio Frequency module operation. Interfacing of transceiver modules to Microcontroller. DC motors working and need for motor driver. Interfacing R
