Review and work into the existing optical reflective speed sensor. Test the sensor with sinusoidal and impulse output signals. Improve the circuit by adding protection functions against overvoltage, reversed polarity, and electrical disturbances. Design the PCBs by Autodesk Eagle. Test and optimize the output signal by adjusting the parameters of the sensor circuit.

Work in an R&D department for the completed development process of mechatronic systems. Convert customers’ needs into actionable product requirements. Design and build prototypes of electric motors for different projects, ranging from the medical device to automotive. Model the controllers for the motors by Matlab/Simulink. Design the PCBs by Altium Designer. Implement the controllers by FPGA (Verilog HDL) and Microcontroller (C/C++). Test and troubleshoot the motors through target machine.

Research in university. Market-oriented improve the design of a robot and its actuator, increasing the performance. Optimize the control system by Microcontroller. Cooperate with Bachelor, Master, PhD members, university technicians, and hospital radiologists. Assist in supervising students regarding their thesis. Register a company and assist in project management. Prepare for website, 3D animations, and videos to commercialize the research result. Search for research funding and partners.

Perform functional and stress test of both hardware and software of computer server systems to meet quality satisfaction. Troubleshoot system failures in test. Quality control and firmware update to meet commercial standards. Report defective issues on a daily repair report. Assist in coordinating new employees. Follow supervisor's instruction and testing procedures and other production duties.

Measurement of the hysteresis in flexure-based mechanisms (a clamped leaf-spring). Investigate the performance of a new concept of mechanical joint based on precision mechanisms. Build an analytical model of the mechanisms. Automate actuator and sensors to allow an automated measurement procedure. Adapt set-up such that sufficient damping of the leaf-spring is introduced. Measure the hysteresis of various leaf-spring, clamp and pre-tension combinations. Document the measurement results.
