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.
