It is estimated that between 2010 and 2014 more than 1.2 lakh deaths were caused by fire accidents in India, according to the National Crime Records Bureau (NCRB). While there are many precautionary measures taken to prevent Fire accidents, they do sometimes occur as a result of natural disasters or human error. Human resources will be used to extinguish a fire in the event of a fire breakout so that people can be rescued. It is very much possible that humans can be replaced with robots for fighting fires thanks to the advancements in technology, especially robotics. Firefighters would be more effective, and they would also avoid endangering people on the job. The goal of this tutorial is to create an Arduino Fire Fighting Robot, which will detect fire and start the water pump automatically

This project will teach you how to make a simple robot that can pump out water around a fire and move towards it to put it out. Once you understand the following robotic basics, it will be easier for you to build more complex robots. Okay, let's start at the beginning.

Arduino UNO Fire sensor or Flame sensor (3 Nos) Servo Motor (SG90) L293D motor Driver module Mini DC Submersible Pump Small Breadboard Robot chassis with motors (2) and wheels (2) (any type) A small can Connecting wires

The Arduino is the main processor of the project. For detecting fire, we are using the Fire sensor module (flame sensor) as shown below. It's possible to see that these sensors are equipped with an IR receiver (Photodiode), which is used to detect fire. This is impossible, how is it possible? An infrared receiver on the sensor module will be able to pick up this light from the fire when it burns. Using an Op-Amp, we then monitor

the voltage change across the IR Receiver, so if there is a fire, our output pin (DO) will be 0V (low) and if there is none, our output pin will be 5V (high). To determine in which direction the fire is burning, we use three sensors located in three directions on the robot. By using the L293D module, we can drive our motors close to the fire once we know the direction in which the fire is coming from. We must use water to put out a fire when near one. The water is carried in a small container, a 5V pump is also tucked inside, and the entire device sits atop a servo motor so that the water can be sprayed from any direction. Now that we have the connections, let's move on As a profession, firefighting is an important one, but it is very dangerous. Robots are designed for that reason, so that they can find a fire before it rages out of control. The system could be used to reduce victims' injury risks by working with fire fighters. Firefighting Robots are compact and portable emergency response robots that assist firefighters, especially in highly dangerous environments where people cannot enter, in fighting high-rise fires

On the following page you'll find the complete schematic for this Fire Fighting Robot. It is either possible to connect each connection to upload the bot to verify its functionality or you can assemble the bot completely. After that, connect the devices. It's very simple to make both connections and you should have no trouble doing it. The container that I am using might not be the same for the robotic chassis that you are using. Set up the pumping system then according to your own creativity. It will, however, continue to be the same code. My pump is housed in a small aluminum can (cool drinks can) that I filled with water and set it in place. In order to control the direction of the water, I assembled the whole can on top of a servo motor. I built my robot in a way that looks like

this. Servo fins were made by hot gluing the bottom of the container to the servo motor, and servo motors were attached to the chassis by nuts and bolts. The container just needs to be placed on top of the motor, then the pump inside it can be triggered to force water outside via the tube. Using the servo to rotate the whole container, the water can be directed in any direction.
