Rachen Wanbunma

Entry-level Robotics and Automation Engineer (GPA 3.29) with a strong focus on system design and mechanical design. Through academic and project-based work, designed 5+ automation and robotics systems from scratch, progressing from microcontroller-based control and PLC-controlled machines to a ROS2-based autonomous mobile robot. Skilled in PLC programming and machine vision, and motivated to grow into a professional automation engineer in a real manufacturing environment.

Design Engineer — Cooperative Education at Sun & Siasun Robot (Thailand) (2025-08 – 2025-12)

Completed a full-time cooperative internship at a robotics and automation system integrator specializing in design, installation, and after-sales service for industrial robot systems, AGVs, AMRs, and ASRS solutions.

• Designed Safety Fence systems for client factories using Autodesk Inventor (3D) and AutoCAD (2D) — including site dimension analysis, material selection, quantity optimization, and floor anchor specification. Designs were deployed at client sites.
• Designed a portable PLC Training Kit from concept to working prototype — a plug-and-play unit integrating PLC, power supply, and I/O modules for automation training.
• Assisted in 2D technical drawings and control panel assembly — mounting electrical components (PLC, breakers, relays, motor drivers, inverters), wiring, and testing before client delivery.

Teaching Assistant — PLC Practical Lab at Kasetsart University, Sriracha Campus (2024-11 – 2025-01)

• Assisted PLC practical lab sessions for over 80 undergraduate engineering students.
• Supported students in PLC programming, automation logic, and I/O wiring.
• Troubleshot PLC programs and hardware connection issues during live lab sessions.
