We designed a robotic arm capable of playing Connect Four against a human, with several difficulty levels. This project strengthened our skills in mechanics (stepper motors, belts), programming (motor control, game algorithm), and electronics (power supply, wiring). We also developed a token dispenser with no mechanical intervention. By combining and modifying open-source plans, we created an autonomous and efficient machine. Our scientific approach included identifying key requirements (precision, autonomy, efficiency, smoothness, adaptability) and leveraging each team member’s strengths.
