Engineering projects and collaborative builds

These case studies document requirements, engineering decisions, testing, and iteration across individual and group projects. Numbers and methods come from project documentation, not from memory.

2026 FRC season

Deployable Multi-Level Climbing Mechanism

A deployable climber that carries the full weight of the robot up multiple bars on alternating carbon-fiber hooks — packaged into three inches of space between the swerve modules and shooter.
