What is a fire fighting robot?

The Firefighting Robot is a compact and portable emergency responder robot that assists firemen in fighting high-rise fires, especially in highly dangerous environments where it is not safe for people to enter.

How it is Controlled by a Smartphone?

We are using the Wi-Fi communication method from the Nodemcu board.

The onboard wifi helps in establishing a communication medium as the control panel to move the robot is being set by a web server that can load on any mobile device.

This is a prototype of the fire-fighting robot car which comes with a lot of advantages.

Advantages of a fire fighting robot car compared to human firefighter

The main advantage is safety, humans take risks to reach the areas but in the case of this robot there is no such risk, you will be controlling the robot with a remote device.

The other thing is this robot can work in a hazardous environment that is a threat to humans, as we breathe air. This problem is solved when this robot car is used.

Although there are many advantages to every creation there is always a positive and negative side.

So coming to disadvantages you can say that the power backup, it drains up the batteries so fast that for a longer period of time, it needs battery replacement.

With this being said let us begin with supplies for building this project.

1. Nodemcu also called as ESP8266
   

2. H-Bridge with L298N motor driver

3. Empty Cardboard box

4. Submersible water pump

5. 18650 batteries x 2

6. Battery holder

7. Switch

8. Jumper wires

9. BO motor and wheels

10. Empty plastic bottle to fill with water

11. Hot glue

12. Ruler and pencil

This is the base and also the main part of this robot, The version of cardboard that I'm using is very strong, and got it from an old mobile phone.

We will use this as a base to hold the BO motor, Start by adding the wheels to the BO motor or few call it as DC gear motor.

Now mark the center point in the cardboard that you are using, Make markings for the BO motor and make a hole.

After which you can insert the BO motor, make sure the wires are inserted first as it is difficult to solder later if something is not right later.

After inserting the motor secure it by adding drops of hot glue, wait for some time, and add one more layer of hot glue since we need extra strength as this part carries the load.

Who invented fire fighting robot?

The first firefighting robots are Thermite RS1 and RS3. Thermite robots were developed by Howe Technology company in 2015. The Thermite firefighting robot is a remotely controlled robotic ground vehicle capable of high-definition, real-time video feedback. Its remote-control range is 300–500 m.
