🚀 Fully automated Arduino assembly line built in 24h for EBEC Challenge '25.
This project was developed as part of the EBEC Challenge '25 in the Innovative Design category. The challenge required our team to design and build a fully functional automated assembly line prototype within just 24 hours. The system was designed to perform four key operations:
✅ Transport products from Zone A to Zone B
✅ Place the product inside a box 📦
✅ Apply a logo to the box 🏷️
✅ Close the box completely, ensuring the product was not visible
To accomplish these tasks, we implemented a fully automated solution using Arduino as our main microcontroller. Our prototype integrated the following components:
🔹 Conveyor Belt: Used to transport the product and drop it into the box.
🔹 Crane System: Controlled by servo motors to move the box between different stations.
🔹 Stamping Mechanism: Responsible for applying the logo on the box.
🔹 LED Indicator: Blinks at startup to indicate system activation. 💡
- 2x Servo Motors (for crane control)
- 3x DC Motors (2 for the conveyor belt, 1 for the stamping mechanism)
- Arduino Microcontroller
- LED Indicator
- L298N Motor Driver Module (for motor control)
We programmed the Arduino using C++, ensuring smooth hardware-software integration. The system was designed to allow continuous operation, enabling seamless box replacement when it reached Zone B.
Our biggest challenge was automating the sticker stamping mechanism. Despite implementing a lever-based system, fine-tuning its precision remained a major obstacle.
✔ Fully Automated Operation
✔ Electronic Control via Arduino
✔ Efficient Crane & Conveyor Integration
✔ LED Startup Indicator
- Time Constraint: Completing the entire system within 24 hours was intense but rewarding.
- Precision and Speed of Movements: Since every action needed to be precise, ensuring both accuracy and speed was a significant challenge.
- PWM Control Issues: The PWM signals were not functioning correctly for the motors to control speed, so we had to simulate PWM by manually pulsing the motor control signals to regulate their movement.
- Hardware-Software Integration: A great learning experience in embedded systems.
This project was an exciting and challenging experience that pushed our engineering and problem-solving skills to the limit. Proud of the dedication and teamwork that made it possible! 🚀
