Mechatronics Engineer · Penang, Malaysia
I'm Liau Zhi Jun, a Mechatronics Engineer who specialises in prototyping and product development. I bring concepts to life with SolidWorks, 3D printing, robotics, and IoT — and I write the clear documentation that turns a prototype into something a team can actually manufacture.
About
I'm a detail-oriented Mechatronics Engineer with a passion for prototyping and product development. I've designed mechanical systems in SolidWorks, brought them to life with 3D printing, and streamlined production with clear working instructions that reduce assembly discrepancies on the factory floor.
My work sits where mechanical design, electronics, and software meet: robotic arms with machine vision, IoT systems on embedded hardware, and electro-pneumatic automation. I graduated from Universiti Malaysia Perlis with First Class honours (CGPA 3.81), building on a diploma with a 3.88 CGPA.
Beyond engineering, I served as an Officer Cadet Sergeant in PALAPES UniMAP and led a publicity team of ten — experiences that sharpened my discipline, leadership, and ability to deliver under pressure.
Experience & education
Designed and prototyped mechanical systems using SolidWorks and 3D printing, cutting prototyping time by 15%. Collaborated with a multidisciplinary team to improve design performance and manufacturing processes, and prepared detailed technical reports to keep quality control on track.
Graduated with First Class honours, CGPA 3.81. Coursework spanned Advanced PLC, Autonomous Mobile Robots, Automation, Control Engineering, and Fluid Power — the foundation behind my robotics and automation projects.
Built First Article prototypes for advanced equipment, ensuring design accuracy and functionality. Created working instructions and checklists to streamline new product introductions, and managed the bill of materials for assembly — reducing discrepancies by 15%.
Graduated with a CGPA of 3.88. Built core skills in applied mechanics, sensors and measurement, and manufacturing processes — the groundwork for everything that followed.
Selected work
A selection of robotics, IoT, and automation systems I've designed and built — from autonomous harvesting robots to smart embedded systems.
An autonomous field robot integrating IoT, robotics, and computer vision. A camera-guided robotic arm detects and picks fruit — cutting labour requirements by 60% — with line-following navigation and a barcoded multi-tier storage rack for tracking.
A robotic system for harvesting tomatoes in vertical farms. A SCARA arm with a Z-axis lift handles height variation across multi-tier setups, paired with a custom end-effector designed for gentle handling to protect delicate fruit.
An IoT-enabled smart park built on the Raspberry Pi Pico with Blynk for communication. The hardware layout uses load cells for real-time weight measurement and space optimisation.
An electro-pneumatic system for automated object handling, combining single- and double-acting cylinders. Circuits were designed and validated in Automation Studio, with a diverging conveyor and cylinder-based lane selection for accurate sorting.
