Obstacle Avoiding Robot

Introduction

Here we are going to see how to make an obstacle-avoiding robot. For making this project we need ultrasonic sensors, BO motors, and a Kblox Neo. An Obstacle Avoidance Robot is an intelligent robot, which can automatically sense and overcome obstacles on its path. It consists of a Microcontroller to process the data, and Ultrasonic sensors to detect the obstacles on its path. Obstacle avoidance is one of the most important aspects of mobile robotics.

Components required

• Kblox Neo
• Ultrasonic sensor
• Chassis
• BO motor [Qty-2]
• Wheels 75mm [Qty-2]
• Castor wheel
• Screw-driver
• Battery 9V
• Battery clip
• A to B USB cable
• Jumper wires  [M-F, Qty-8]

Code

#include"kblox.h"         

kblox kit;

void setup() {

  Serial.begin(9600);
  kit.motor_begin(12, 11, 5, 3);    //define motors pins
  kit.ultrasonic_begin(8, 9);       // define ultasonic pins

}

void loop() {
  int d = kit.ultrasonic_read();   //read distance and store in variable 
  Serial.println(d);               //print data serially 
  if (d >= 25) {                   // if distance is more than 25 move bot forward 
    kit.forward();
  }
  else {

    kit.right();                   // if distance is less than 25 move bot right
    
  }

}

Applications

• It can be used in automatic vacuum cleaning
• It can be mobile robot navigation
• They can also be used in dangerous environments, where human penetration could be fatal.
