Fire Extinguisher Car

harjinagi

15 Oct 2020

Hello Everyone,My name is Harji Nagi.I am currently a second year student studying electronics and communication engineering from Pranveer Singh Institute Of Technology,Kanpur(UP).I have a keen interest in robotics,arduino,Artificial Intelligence and Analog electronics.

Watch out the vedio => https://youtu.be/G-b0pVjgYRE

Today I made a bluetooth control "FIRE EXTINGUISHER CAR" via Arduino Uno ,Motor Driver Shield,HC-05 Bluetooth Module and Relay module.I made this with my own experience and knowledge on Arduino.This car can be controlled with your mobile via bluetooth module.And can extinguish fire.And arm for controlling the direction of water pipe.It can rotate up to 360 degree.

The component list are:

1)Motor Driver Shield

2)Arduino Uno

3)Relay Module

4)Car chassis ( 4*BO Motor)

5)One 3.3-5 V Submersible Water Pump with 30cm pipe

6)10 RPM DC Metal gear motor

7)Hc-05 Bluetooth Module

8)Jumper Wires

9)8V,1.5 Amp Battery for powering Arduino Uno and Motor Driver Shield

10)4V,1 Amp Battery for Submersible Pump or you can use 7805 Voltage regulator Ic

Other Equipments:

1)Soldering Iron

2)Glue Gun

Instead of using breadborad I have use small coustom pcb for positive and negative bus connection.

Step 1: Connection of BO Motor With Arduino Motor Driver Shield

                                                                           image

Solder 2 wires to your BO motor. Next, connect the other ends of the wires to the 2 hole sockets on the Motor Driver Shield.The order of how you connect the wire doesn't matter. Repeat this for the other motor.

Do the connection as per the Circuit Diagram.

Take 8v,1.5Ampere battery pack and attach to M+ and ground pin of motor driver shield.This will be used to achieve a common ground with the arduino later.

Step 2: Connection of Submersible Pump With Relay

 

 

                                                                                               Connection of Submersible Pump With Relay

 

 

You can use either Relay module or you can build your own custom relay module.As a power supply You can either 7805 Voltage regulator IC to convert 8V dc to 5V dc or you can use external power supply of 4V,1ampere battery.But remember not to use more than 6v it can damage 5v submersible pump.

For more water pressure 12V water submersible pump is also available in the market but you have to change the circuit connection and power supply according to it.

Follow the circuit diagram as per instruction.

Step 3: Arm for Controlling the Direction of Water Pipe

For changing the direction of motor I am using 12V ,10 RPM DC metal gear motor.Solder the wires of dc motor.Next, connect the other ends of the wires to the 2 hole sockets on the Motor Driver Shield.Connect in M4 socket,as per according to code.

Step 4: Watch This Vedio for More Details

The code and hardware details are given in this link.Click Here.

And for controlling the car,You can use any Arduino Bluetooth Controller App.

Thank You.

Step 5: Summary

We will need 4 motors for car,one motor for controlling the direction of pipe and one water pump. Motor driver shield to drive the motorA brain, in our case arduino, is needed to command the robot how to move.We can use our phones as a remote control for our RC car .If you want to use your computer however, pair your computer with the bluetooth module, go to bluetooth settings which is found at the end of the bluetooth configuration page, check which port is it connecting to (tip: it is outgoing and has the name of your bluetooth module). Go to tools > serial ports and change the COM to the correct COM port. Fire up Serial monitor and enter 'F' for the robot to move forward, 'B' to move backward,'L' to move Left,'R' to move Right etc.For controlling water pump you can use on off switch in app.And for adjusting the direction of water pipe you can use 'X' and 'Y' key for left and right. If you've made this far, congratulations! Have fun with your Fire Extinguisher Car.

    your fire truck made me smile. I would take this to the local coffee shop, re-fill ladie's coffee and tea cups as a way to introduce myself. Its also a fun way to water plants.

    Hi Gary,

     

    Using this prototype in coffee shops so you need many changes like  you have to install the lidar sensor, raspberry pi  that plots the maps of it's sourroundings and helps in obstacle avoidance.And building such diy autonomous robots that takes and receive order and serve on a particular coustomer table is quite tricky and expensive.For ordering you can use nrf one transmitter and many receiver with different id.So it's cool idea,if you wish you can implement it.

     

    Now if I talk about the fire extinguisher car it's just a prototype if it's built in a large scale it could save many lives.

    And using this prototype aa watering plants it would be the funniest thing.

     

    Harji.
