Robotics + controls

Teradyne senior design project

This project focused on automating coaxial connector mating during test procedures with a Cartesian robot, tool-changing logic, and sensing-informed control.

What I contributed

I handled the programming side of the robot, including remote operation, automatic tool changing, load-cell-based closed-loop control, and a redesigned GUI for running automation workflows more clearly.

What came out of it

The project reached 0.01 mm travel precision and 0.5 g load standard deviation, and the work was associated with an IEEE publication.

An early CAD-stage view of the redesign, used to work through the mechanical layout before integration.

Assembly and integration

Assembly and integration

Initial assembly with linear rails, anti-backlash hardware, and the base structure for the coupling setup.

Load-cell characterization
