Picture of CUSTOM BUILD 4WD BLUETOOTH RC ROBOT USING PVC

Hi guys this is my second project done by pvc , you may wonder why i choose pvs to built my projects, coz i have bunch of pvc which are leftovers of my house plumping work .and i dont wanna waste them .

PROJECT DETAILS

This is a simple Bluetooth based 4 wheel drive rc robot built in pvc frame , the advantages of this frame are

  1. It is strong and stable.
  2. so easy to make.
  3. high load capability.

  4. low cost (for me its free of cost)

  5. most important thing is it can give equal amount of pressure for all 4 wheels
  6. so its 99.9% accurate (means it can go straight )


    The reason why i discovered this idea:- i live in a place where there is less availability of robotics parts ,
    the only frame which i can get from those shop is the one which built with metal sheet ,for cheep rate .but thats notstable ,some times all wheel wont touch the ground equally and unequal distribution of force ,it cause the robot to show improper movements while its turning .

The program for the roboat is so simple
char val; 
int a1= 5; int a2= 6; int b1= 9; int b2= 10; int l1= 13; void setup() {
  pinMode(a1, OUTPUT);  
  pinMode(a2, OUTPUT);  
  pinMode(b1, OUTPUT); 
  pinMode(b2, OUTPUT);  
  pinMode(l1, OUTPUT);  
  
  Serial.begin(9600);       
}
void loop() {
  if( Serial.available() >0 )       
  {
    val = Serial.read(); 
Serial.println(val);     
  }
  if( val == 'F' )               
  {
    digitalWrite(a1, HIGH);  
    digitalWrite(a2, LOW);
    digitalWrite(b1, HIGH);  
    digitalWrite(b2, LOW); 
  }
      
  if( val == 'B')
 {
    digitalWrite(a1, LOW);  
    digitalWrite(a2, HIGH);
    digitalWrite(b1, LOW);  
    digitalWrite(b2, HIGH); 
  }
  
if( val == 'R' )               
  {
    digitalWrite(a1, HIGH);  
    digitalWrite(a2, LOW);
    digitalWrite(b1, LOW);  
    digitalWrite(b2, HIGH); 
  }
    
if( val == 'L' )               
  {
    digitalWrite(a1, LOW);  
    digitalWrite(a2, HIGH);
    digitalWrite(b1, HIGH);  
    digitalWrite(b2, LOW); 
  }
  if( val == 'S' )               
  {
    digitalWrite(a1, LOW);  
    digitalWrite(a2, LOW);
    digitalWrite(b1, LOW);  
    digitalWrite(b2, LOW); 
  }
  if( val == 'G' )               
  {
    digitalWrite(a1, LOW);  
    digitalWrite(a2, LOW);
    digitalWrite(b1, HIGH);  
    digitalWrite(b2, LOW); 
  }
  if( val == 'I' )               
  {
    digitalWrite(a1, HIGH);  
    digitalWrite(a2, LOW);
    digitalWrite(b1, LOW);  
    digitalWrite(b2, LOW); 
  }  
    if( val == 'J' )               
  {
    digitalWrite(a1, LOW);  
    digitalWrite(a2, HIGH);
    digitalWrite(b1, LOW);  
    digitalWrite(b2, LOW); 
  }  
    if( val == 'H' )               
  {
    digitalWrite(a1, LOW);  
    digitalWrite(a2, LOW);
    digitalWrite(b1, LOW);  
    digitalWrite(b2, HIGH); 
  }  
  
  delay(100);    
       
 if( val == 'X' )               
  {
    digitalWrite(l1, HIGH);  
  } else { 
    digitalWrite(l1, LOW);   
  }
 
}

Step 4: Finalizing

Hope you guys liked my project.if so please do vote for me :)

i guess this bot is one of the easiest project in instructables. Enjoy!!


Thanks

Step 5: Testing Video

PLEASE DO VOTE FOR ME(not aiming for 1st/2nd prize)

how do i add an led command in the ardino to control with Bluetooth app
tominjose (author)  nemeen3 months ago

Just add these commands
if( val == 'X' )

{

digitalWrite(l1, HIGH);

}

if( val == 'x' )

{

digitalWrite(l1, LOW);

}

halo pak, bisakah saya menggunakan driver motor L298? ataukah saya harus menggunakan driver motor L293D?.

dan bisakah saya menggunakan baterai 9v untuk robot itu? saya menggunakan motor dc 710 RPM. Terimakasih sebelumnya...

l298.jpg

hello sir, can I use the L298 motor driver? or do I have to use the L293D motor driver ?.

and can I use a 9v battery for the robot? I use a dc motor 710 RPM. Thank you in advance ...

I'm a beginner ...

my project have a delay at least 7-10 secs. before it move, i don't know why, please help me...

tominjose (author)  jasper.alcular10 months ago

Delay is because ,app you are using is latest version ,there are few bugs on latest version try to use old version ,it may solve your problem

Thanks for the response.. Can you give me your zip file for the old version of your application? Thank you in advance :))..

tominjose (author)  jasper.alcular10 months ago

Sure! give me your mail id.

no need to the zip file, after finishing i will vote
