The document describes a firefighting robot that is designed to help extinguish fires and reduce risks to human firefighters. It uses sensors like infrared sensors to detect fires and water tanks to help put out flames. The robot is controlled remotely and can navigate autonomously using six legs. It has advantages like reducing risks to firefighters and allowing access to dangerous areas. However, it also has limitations like not being able to operate for long periods without recharging and not being able to replace human firefighters for large fires. The robot aims to help detect fires quickly and minimize financial losses and threats to human life.

- 3. RObOT • Robot 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.
- 4. Why fiREfighTER RObOT ? • robots decrease the need for firefighters to get into dangerous situations. • the load for fire fighters reduced. • it is impossible to extinguish fire and rescue many victims at a time in a huge disaster. • They may be remote control machines. • The vehicles can reach positions that firefighters cannot, such as petrochemical complexes and huge warehouses fire. • a robot can function by itself .
- 5. 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.
- 6. SpECifiCaTiONS • Made from fire-resistant ceramic-fiber compounds, silicon elastomer,polyaramid fabric. • Can sustain up to 138 kpa. • • The robot is equipped with tanks of water and powdered fire extinguishing agents.

- 10. Software and Hardware requirementS Software Tools: •WINAVR to compile the source file and generate the hex code. •ATmel to programmer the microcontroller Hardware Tools: •AVR(advanced virtual RISC) Microcontroller •IR Sensor •DC motors •Pump
- 11. motor driVer •L293D is a typical Motor driver or Motor Driver IC which allows DC motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. It means that you can control two DC motor with a single L293D IC. •The L293d can drive small and quiet big motors as well.
- 12. Cont. Concept •It works on the concept of H-bridge. H-bridge is a circuit which allows the voltage to be flown in either direction. As we know voltage need to change its direction for being able to rotate the motor in clockwise or anticlockwise direction, hence H-bridge IC are ideal for driving a DC motor.
- 13. PumP A pump is a device that moves fluids (liquids or gases), or sometimes slurries, by mechanical activity. The power, P, required by the pump: where ΔP is the change in total pressure between the inlet and outlet (in Pa), and Q, the fluid flowrate is given in m³/s.
- 14. ir SenSorS • Infrared red(IR) light is electromagnetic radiation with longer wavelengths than those of visible light, extending from the nominal red edge of the visible spectrum at 700 nanometers (nm) to 1 mm. This range of wavelengths corresponds to a frequency range of approximately 430 THz down to 300 GHz. Most of the thermal radiation emitted by objects near room temperature is infrared. • IR sensors can measured heat and detect motion of objects.
- 15. 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
- 16. effectorS • Effectors are the means by which robots manipulate the environment and give the signals. • End effector is the device at the end of a robotic arm, designed to interact with the environment.
- 17. 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.

- 19. 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.
- 20. ROBOT DEPLOyED IN FIRE DEPARTMENT •Monitor nozzle vehicle •Reconnaissance robot •Underwater robot •Rescue robot
- 21. MONITOR NOZZLE VEHICLE • The vehicles can reach positions that firefighters cannot, such as petrochemical complexes and huge warehouses fire. • Which is used in small tunnels that firefighters cannot enter. • The vehicle is carried by a fire engine with a robot controller. • The robot moves with a double pair of crawlers. • Its camera turns following the monitor nozzle.
- 22. RECONNAISSANCE ROBOT • The robot is equipped with a manipulator, two TV cameras, infrared camera, gas detector, thermal camera. • The manipulator has 6 degrees of freedom and the robot moves with four crawlers • Utilizing the manipulator and crawlers, the robot can open doors and enter hazardous rooms. • The robot looks like a radio-controlled car with a camera and detectors.
- 23. uNDERwATER SEARCHING ROBOT The ole type robots are equipped only cameras for searching new type has sonar and thermal sensors in addition. •The robot is used for searching victims in fire. •The searching area is just near coast, in port of a big city, or in river. The water is not clear in many cases, so the TV camera is not useful for searching rather. •Therefore the sonar is very necessary for the robot.
- 24. Minimization of – financial loss –a threat to a human life 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
- 25. Limitations •Many believe it will be a better scout than firefighter. •Cannot leave outside for long periods of time due to power supply. •It is not meant to put out large fires. •Doesn’t predict nor interfere with operator’s thoughts.
- 26. 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.
- 27. FUtURE scopE • The development of sensor networks and the maturity of robotics suggests that we can use mobile agents for tasks that involve perception of an external stimulus and reacting to the stimulus, even when the reaction involves a significant amount of mechanical actions. However, there has been research on many of these pieces in different contexts, e.g., coordination among mobile agents, techniques for detecting and avoiding obstacles. It will be both interesting and challenging to put all this together into a practical, autonomous fire-
