Introduction: Gesture Controlled Robotic Car

Hi,

This is my 13th instructable and in this tutorial, I'm going to show you, how to build a simple Gesture Controlled Robotic Car by using Arduino, accelerometer and RF modules.

Before getting started just hit the vote button because i need a new laptop for my projects i think you guyzz help me...

let's start with component we need

Step 1: Components and Software

Picture of Components and Software
  1. Arduino Board
  2. RF315/433 module
  3. Wires, Pins
  4. Accelerometer
  5. L293d
  6. Encoder and Decoder
  7. Motors, Wheels & Caster Wheel
  8. Glove
  9. General purpose pcb, Soldering iron
  10. Power source

Step 2: Circuit Diagram, Soldering, Connections

Picture of Circuit Diagram, Soldering, Connections

Make connection as mention below for the glove

For Gyroscope.

  • Connect "SDA" from your accelerometer to analog pin 4(A4) of the Arduino.
  • Connect "SCL" from your accelerometer to analog pin 5(A5) of the Arduino.
  • VCC to arduino 3.3v pin.
  • GND to arduino GND pin.

For Transmitter Module

  • Connect VCC to arduino 5v pin.
  • Connect GND to arduino GND pin.
  • Connect Rest of pins of ENCODER & TRANSMITTER as per the Figure 1.
  • At last connection for battery.

Make connection as mention in Figure 5. for the receiver(robotic car).

Step 3: Code

Picture of Code
#include<wire.h>
const int MPU_addr=0x68;  // I2C address of the MPU-6050
int16_t X,Y,Z;
void setup()
{
  pinMode(10,OUTPUT);
  pinMode(11,OUTPUT);
  pinMode(12,OUTPUT);
  pinMode(13,OUTPUT);
  Wire.begin();
  Wire.beginTransmission(MPU_addr);
  Wire.write(0x6B);  // PWR_MGMT_1 register
  Wire.write(0);     // set to zero (wakes up the MPU-6050)
  Wire.endTransmission(true);
  Serial.begin(9600);
}

void loop()
{
  Wire.beginTransmission(MPU_addr);
  Wire.write(0x3B);  // starting with register 0x3B (ACCEL_XOUT_H)
  Wire.endTransmission(false);
  Wire.requestFrom(MPU_addr,14,true);  // request a total of 14 registers
 X=Wire.read()<<8|Wire.read();  // 0x3B (ACCEL_XOUT_H) & 0x3C (ACCEL_XOUT_L)    
 Y=Wire.read()<<8|Wire.read();  // 0x3D (ACCEL_YOUT_H) & 0x3E (ACCEL_YOUT_L)
 Z=Wire.read()<<8|Wire.read(); // 0x3F (ACCEL_ZOUT_H) & 0x40 (ACCEL_ZOUT_L)

  Serial.print("AcX = "); Serial.print(X);
  Serial.print(" | AcY = "); Serial.print(Y);
  Serial.print(" | AcZ = "); Serial.println(Z);

  delay(333);
  if(X > 3000 && X < 7000 )
  {
    digitalWrite(10,LOW);
    digitalWrite(11,HIGH);
    digitalWrite(12,LOW);
    digitalWrite(13,HIGH);
    }
 else if(X < -3000 && X > -7000 )
  {
    digitalWrite(12,HIGH);
    digitalWrite(13,LOW);
    digitalWrite(10,HIGH);
    digitalWrite(11,LOW);
    }
else if(Y < -3000 && Y > -7000 )
  {
    digitalWrite(12,LOW);
    digitalWrite(13,HIGH);
    digitalWrite(10,HIGH);
    digitalWrite(11,LOW);
    }
    else if(Y > 3000 && Y < 7000 )
  {
    digitalWrite(12,HIGH);
    digitalWrite(13,LOW);
    digitalWrite(11,HIGH);
    digitalWrite(10,LOW);
    }
  
    else
    {
      digitalWrite(10,LOW);
      digitalWrite(11,LOW);
      digitalWrite(12,LOW);
      digitalWrite(13,LOW);
      }   
}

This is really cool! If you worked a bit on the aesthetics I'm sure you could get a lot more attention.
