Project Abstract

From the recent years, robotics has turned out to be an ingredient over which many people had shown their interest. Robotics has gained popularity due to the advancement of many technologies of computing and nanotechnologies. So, as a part of my Final year Engineering Projects, I have decided to design something that can make humans life easier and comfortable. Here my interest in the review is to make a fully automated firefighting robot which can help in dealing with many fire problems in households and small-scale industries. Now I am not concentrating on making a firefighting robot that can deal with a fire on a large scale because I want to proceed by step by step. The need of the hour is to make a device which can detect fire, even if it is small and take the necessary action to put it off. Many household items catch fire when someone is either sleeping or away and that leads to many hazardous conditions if the fire is not put off in time. So, my work as an electronics and computer engineer is to design and build a system that can automatically detect and extinguish the fire. I have used very basic concept here, easy to understand from the perspective of beginners or for the masters of this field. I hope my projects will be helpful to all Final year Engineering Students.

Final Year Engineering Projects on Fire fighting Robot

Fire Fighting Robot Model


My research paper describes the design of a small autonomous Fire Fighting Robot. I have worked on the same project at my college presenting a synopsis showing its basic construction and working. The Fire Fighting Robot is an electronics project designed to search for a fire in a small floor plan of a house of the specific dimensions, extinguish the fire with the help of the front fan of a toy hovercraft, and then return to the front of the house. This mission is divided into smaller tasks, and each task is implemented in the most efficient manner such as self-autonomous start of the robot, navigation of the robot in every room step by step, finds the fire in a specific room, approaches the fire at a very fixed distance, extinguishes it and finally returning to the front of the house. The self-start of the robot is governed by a Tone Decoder which detects the tone of frequency up to 3.5 kHz which is emitted by a fire alarm during the fire. The navigation of the robot throughout the house is achieved by data provided by a line tracker and ultrasound transducers. Finding the target or fire is achieved by the Flame Sensor which detects the temperature density in various parts of the floor plan. This is accompanied by UVTron flame sensor. The deployment of the extinguishing device is implemented with a fan controlled by servos. The very important and crucial concept of this Fire Fighting Robot is that it navigates and extinguishes the candle by colliding with the wall of the floor plan to the least extent.


Fire Detector and Extinguisher Robot are operated to detect the fire and also to extinguish it. It can be operated in two modes one is manual mode and other is autonomous mode. Manual mode is operated using joysticks and for autonomous mode, there is no human intervention. In manual mode direction of the robot is controlled using joysticks, even pump is operated manually. In autonomous mode IR sensors are used to detect the fire and robot is coded accordingly to move in the direction of detected fire. In this robot has a switch which is used to switch between manual and autonomous mode.

The main components are :

  • IR sensors
  • Joysticks
  • Motor drivers
  • DC motors
  • Pump
  • IR Sensors:

                   IR Photo Diodes are used as sensors. These sensors are connected to ADC pins of the microcontroller. IR  Photodiodes are connected in reverse bias to be operated as photodiodes otherwise they will be operated as normal diodes. The voltage variations of the sensors are given as inputs to the Microcontroller and accordingly, the robot is operated.

  • Joysticks:

                  The direction of the robot is controlled using joysticks. The terminals of joysticks are connected to ADC pins of a microcontroller. Joysticks are usually the potentiometer, the potential variations are given as an input to microcontroller and robot is operated accordingly.

  • Motor Drivers:

               Motor drivers are used to describing the direction of movement of the robot. It is used to give high voltage and high current as an output to run the motors which are used in the project for the movement of the robot.

  • DC Motors:

            In this project, we use simple DC motor for the rotation of the wheel which is responsible for the movement of the robot. Usually, DC motors convert electrical energy into mechanical energy.

  • Pump:

            The pump is a mechanical device which is used to pump water on to the fire to extinguish it. It uses a simple motor to pump water.


  • Can be used in record maintaining rooms where fire can cause loss of valuable
  • Can be used in Server rooms for immediate action in case of fire
  • Can be used in extinguishing the fire where the probability of explosion is high. For eg. 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 centres.

Advantages of Fire Fighting Robot

  • Prevention of dangerous incidents
  • Minimization of
  • ecological consequences
  • financial loss
  • a threat to a human life
  • Needs no micro-controller programming.
  • The reconstruction of the curse of operator’s work

Disadvantages of Fire Fighting Robot

  • Doesn’t predict nor interfere with operator’s thoughts.
  • Cannot force directly the operator to work
