Project

Design and fabrication of a 3-dimensional capacitive-based force sensor

  • Conducted structural and electromechanical analyses in COMSOL to optimize the design
  • Designed the parts using SolidWorks and built test prototypes using 3D printers
  • Generated G-codes in Fusion 360 and fabricated the final parts using a CNC machine and machine shop tools
  • Designed a printed circuit board (PCB) in EasyEDA for high-resolution capacitance measurement
  • Developed firmware for real-time data acquisition and transmission via I2C and UART communication

A robotic manipulator for applying 3-directional force

  • Designed and 3D-printed a custom end-effector for improving the adaptability
  • Used Arduino to control the motion of the manipulator and integrated force sensors to measure applied forces

Interactive Image Processing Toolkit

  • Implemented spatial and morphological image processing algorithms in C++ without external libraries
  • Designed a Qt-based GUI for real-time visualization and interactive tuning of algorithm parameters

Temperature Logger

  • Used a temperature sensor to measure temperature and a 4 digit 7 segment display to show the current temperature
  • Used a Raspberry Pi as a web server and published temperature readings on a web page

Automation of a water treatment system

  • Used Autocad Plant 3d to model the water treatment plant and RSLogix Micro for PLC programming
  • Used Wonderware to design the human machine interface (HMI) and Microsoft SQL Server for data extraction
