DIY Sweeper Robot – Build Your Own Cleaning Bot! 🤖🧹

Want to make your own robotic sweeper at home? This DIY project is easy and fun! Let’s build a simple automatic cleaning robot using basic electronics and components.

---

🛠️ Materials Needed:

✅ Arduino Uno (Microcontroller)
✅ 2 DC Motors (For movement)
✅ Motor Driver Module (L298N)
✅ IR Sensors / Ultrasonic Sensor (For obstacle detection)
✅ Small Brush / Microfiber Cloth (For sweeping)
✅ Rechargeable Battery Pack
✅ Wheels & Chassis (For the robot’s body)

🔗 Steps to Build the Sweeper Robot:

Step 1: Assemble the Chassis 🏗️

• Use cardboard, acrylic sheet, or plastic to make the robot's base.
• Attach DC motors and wheels to the chassis.

Step 2: Connect the Motors & Motor Driver ⚙️

• Connect DC motors to the L298N motor driver.
• Connect motor driver to Arduino for motor control.

Step 3: Attach the Cleaning Mechanism 🧹

• Fix a small rotating brush or microfiber cloth to the bottom.
• Use a small motor to rotate the brush.

Step 4: Add Sensors for Obstacle Avoidance 🔄

• IR sensors will detect walls and objects.
• Ultrasonic sensors can be used for better accuracy.

Step 5: Write the Code & Upload to Arduino 💻

• Program the robot to move forward, change direction when an obstacle is detected, and control the brush motor.

🖥️ Sample Code (Arduino C++)

cpp
#include <AFMotor.h>

AF_DCMotor motor1(1);
AF_DCMotor motor2(2);
int sensor = 7; // IR sensor pin

void setup() {
  pinMode(sensor, INPUT);
}

void loop() {
  if (digitalRead(sensor) == HIGH) { // No obstacle
    motor1.setSpeed(150);
    motor2.setSpeed(150);
    motor1.run(FORWARD);
    motor2.run(FORWARD);
  } else { // Obstacle detected
    motor1.run(BACKWARD);
    motor2.run(BACKWARD);
    delay(500);
    motor1.run(RELEASE);
    motor2.run(RELEASE);
  }
}

🔹 Final Testing & Improvements

✅ Test the robot on different surfaces (tiles, wood, carpet).
✅ Upgrade to a vacuum motor for a more powerful cleaning effect.
✅ Add a rechargeable battery for better performance.
