This project embodies innovation and creativity by utilizing track belts, an Arduino Uno microcontroller, and a motor driver shield to create a versatile robotic car. Designed to traverse challenging surfaces, this project engages students in practical robotics while promoting problem-solving and robotics skills.
Upon powering on, it initiates movement forward regardless of the surface condition, thanks to its track belts. The track belts provide enhanced traction, allowing the bot to navigate smoothly over rough terrain such as uneven surfaces that normal wheeled bots might struggle with. This capability not only demonstrates the bot’s resilience but also teaches students about the importance of adaptability in robotics.
The Arduino Uno microcontroller, coupled with the motor driver shield, controls the bot’s two DC motors. The motors are configured to rotate the track belts continuously in the forward direction, ensuring consistent movement. Importantly, even if the bot is accidentally flipped upside down, the track belts enable it to continue operating, showcasing the project’s robust design and reliability.
The circuit diagram and code is given below:
// Define motor driver pins
const int motorA1 = 8; // Motor A control pin 1
const int motorA2 = 9; // Motor A control pin 2
const int motorB1 = 10; // Motor B control pin 1
const int motorB2 = 11; // Motor B control pin 2
void setup() {
// Set motor driver pins as output
pinMode(motorA1, OUTPUT);
pinMode(motorA2, OUTPUT);
pinMode(motorB1, OUTPUT);
pinMode(motorB2, OUTPUT);
// Initialize motors to move forward
digitalWrite(motorA1, HIGH);
digitalWrite(motorA2, LOW);
digitalWrite(motorB1, HIGH);
digitalWrite(motorB2, LOW);
}
void loop() {
// Keep the motors running forward continuously
digitalWrite(motorA1, HIGH);
digitalWrite(motorA2, LOW);
digitalWrite(motorB1, HIGH);
digitalWrite(motorB2, LOW);
}
