Predictive Maintenance Discovery and Application on Motors

Capstone Project, Summer 2021

• Built a predictive maintenance system that collects and analyzes data from sensors and determines if the machine needs maintenance.
• Studied the characteristics of vibrations on a brushless DC (BLDC) motor.

Real-Time Audio Separation of Human Voices

Capstone Project, Winter 2021

• Implemented a hardware system that takes in mixed audio sources and plays back separated audio as output.
• Focused on faster response and improved program performance to output the audio in a short time.

Extrusion Control for Fused Deposition Modeling

Research Project, Fall 2019 - Fall 2020

• Improved print quality of fused deposition modeling (FDM) which is often inconsistent due to the lack of feedback control.
• Integrated feedback with the printer and built an extrusion controller for a commercial FDM printer through G-Code manipulation.
