Raspberry Pi Vacuum Robot Replication
Budget: $15 – $25 USD
---
Project Goal:
Recreate the vacuum robot wiring (as shown in the provided Arduino-based video) using a Raspberry Pi 4, with a detailed simulation and explanations.
---
Main Components Needed:
1. Raspberry Pi 4 (Model B)
2. Motor Driver Module (L298N or similar)
3. DC Motors (2x for wheels)
4. Mini Vacuum Fan (DC fan)
5. Power Source (Li-ion battery or power bank)
6. IR Sensors or Ultrasonic Sensors (for navigation)
7. Jumper wires, breadboard (optional for prototyping)
---
Wiring Overview:
Raspberry Pi GPIO Pins will be used to control the motor driver (for motors and fan).
L298N Motor Driver:
IN1/IN2 for one motor (Left)
IN3/IN4 for second motor (Right)
ENA/ENB to control speed (via PWM from Pi)
Connect vacuum fan to one of the motor channels if controlled, or directly powered from the battery if always-on.
Fan Wiring:
If powered through motor driver: Controlled via GPIO
If directly from power: Use transistor + GPIO to switch it
---
Simulation Suggestion:
Use Fritzing or TinkerCAD (limited Pi support) to create the circuit. For best quality, a Fritzing diagram with clear labels, wire colors, and annotations would work well.
---
Explanation Section (for your entry):
Include:
GPIO pin assignments
Motor driver control logic
Power supply routing
Optional: Python code snippet to show
