Project
Design and fabrication of a 3-dimensional capacitive-based force sensor
- Performed structural and electro-mechanical analyses in COMSOL to design the sensor
- Designed the parts using SolidWorks and built test prototypes using a 3D printer
- Generated G-codes using Fusion 360 and fabricated the final parts using a CNC machine and machine shop tools
- Designed the printed circuit board (PCB) using EasyEDA and soldered the components on the PCB board
- Programmed the microcontroller to collect and transmit capacitance data using I2C and UART communication
- Calibrated the sensor and performed evaluation tests to assess the performance of the developed sensor
A robotic manipulator for applying 3-directional force
- Modified the design of the end-effector and built it using a 3D printer
- Used Arduino to control the motion of the manipulator and collect data from force sensors to measure the applied force
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
