This project was developed as a course-based academic project at Politeknik Caltex Riau between March–July 2025, as part of my mechatronics studies. The objective of the project was to apply classroom knowledge in mechanical design, automation, and system integration by transforming a SOLIDWORKS-based CAD design into a functional automated sorting conveyor prototype.

The prototype was designed as a learning-focused proof of concept, capable of sorting objects based on material type (metal and non-metal) and color. Through this project, I experienced the complete engineering workflow—from digital modeling and design validation to fabrication, assembly, and system testing.

My Specific Contributions

Mechanical Design
I led the mechanical design using SOLIDWORKS, developing the conveyor frame, transmission system, and sorting mechanism. The design emphasized manufacturability, structural integrity, and alignment with the learning objectives of the course.

Fabrication & Assembly
I carried out the fabrication and mechanical assembly of the system, including wiring the electrical control panel. This phase translated theoretical design into real components while addressing practical constraints encountered in a workshop environment.

System Integration
I collaborated on integrating inductive proximity sensors and color sensors with the sorting actuators. This integration enabled the conveyor to perform automated object classification, reinforcing my understanding of sensor-based control systems.

Learning Outcomes

This project resulted in a working automated sorting conveyor prototype and provided hands-on experience in applying CAD, mechanical design, and industrial automation concepts learned in class. It strengthened my ability to connect theoretical coursework with real-world engineering implementation.

“For me, engineering does not stop at the screen. A design only becomes meaningful when it can be realized and tested in the real world. Through this project, I challenged myself to turn what I created in SOLIDWORKS into a working automated sorting conveyor prototype. This process showed me that CAD is not just about modeling parts, but about understanding how ideas behave when faced with real constraints. Seeing a digital design evolve into a functional system boosted my confidence as an engineering student and reinforced my belief that the strongest learning happens when theory, design, and hands-on implementation come together.”
