Importance and Utility of Robotics

Robotics is a rapidly growing field that combines engineering, computer science, and mathematics to create intelligent machines capable of performing tasks autonomously or with human guidance. The use of robotics has expanded across various industries, including manufacturing, healthcare, agriculture, and even entertainment.

The importance of robotics lies in its ability to automate repetitive and dangerous tasks, improve efficiency and accuracy, and enhance human capabilities. By utilizing sensors, actuators, and algorithms, robots can perceive their environment, make decisions, and execute actions accordingly. This technology has the potential to revolutionize industries, increase productivity, and improve the quality of life.

Project: Line-Following Robot

In this example project, we will create a line-following robot using an Arduino board. The goal of the project is to design a robot that can follow a black line on a white surface autonomously. The robot will utilize infrared sensors to detect the line and make necessary adjustments to stay on track.

List of Components:

• Arduino Uno (1x) - Link to purchase
• Motor Shield (1x) - Link to purchase
• Infrared Line Sensor Module (2x) - Link to purchase
• DC Motors (2x) - Link to purchase
• Wheels (2x) - Link to purchase
• Jumper Wires - Link to purchase
• Breadboard - Link to purchase

Examples:

1. Initializing the robot:

   
   #include <AFMotor.h>

AF_DCMotor motor1(1); AF_DCMotor motor2(2);

void setup() { // Initialize motors motor1.setSpeed(255); motor2.setSpeed(255); }

void loop() { // Code for line following algorithm goes here }

2. Line following algorithm:
```arduino
#include <AFMotor.h>

AF_DCMotor motor1(1);
AF_DCMotor motor2(2);

void setup() {
  // Initialize motors
  motor1.setSpeed(255);
  motor2.setSpeed(255);
}

void loop() {
  // Read sensor values
  int leftSensor = analogRead(A0);
  int rightSensor = analogRead(A1);

  // Adjust motor speeds based on sensor readings
  if (leftSensor < 500 && rightSensor < 500) {
    // Both sensors detect the line
    motor1.run(FORWARD);
    motor2.run(FORWARD);
  } else if (leftSensor < 500) {
    // Only left sensor detects the line
    motor1.run(BACKWARD);
    motor2.run(FORWARD);
  } else if (rightSensor < 500) {
    // Only right sensor detects the line
    motor1.run(FORWARD);
    motor2.run(BACKWARD);
  } else {
    // Both sensors do not detect the line
    motor1.run(FORWARD);
    motor2.run(BACKWARD);
  }
}

This example code initializes the motors and implements a basic line-following algorithm. The robot reads the sensor values, adjusts the motor speeds accordingly, and moves in the desired direction to stay on the line.
