3-Axis Soft Metrology Rig

Currently Designing a calibration rig to characterize soft sensors at sub-micron precision, generating paired force-input and signal-output datasets under a $1,500 budget cap.

Benchmarked eight actuator technologies — ball screws, voice coils, and three classes of piezoelectric stage — before landing on a Teensy 4.1 driving Thorlabs servo-actuators via low-level hex commands, paired with a Series Elastic Actuator to filter mechanical noise. Created a 0.4mN precise PID force loop.

Automated Robotic Guitar

Led development of an automated robotic guitar integrating plucking, strumming, and muting mechanisms with a solenoid fretting system.

Spearheaded end-to-end design of a bidirectional strumming subsystem and a selective string-muting mechanism to expand dynamic musical range.

The QuickLift

Designed and prototyped a mechanical lift attachment for manual wheelchairs, enabling independent seat height adjustment up to 6 inches.

Validated models via structural FEA. Utilizes a scissor jack mechanism with a custom U-shaped steel base plate and an extended ergonomic 3D-printed hand crank.
