Gavin Worrell’s Transmedium Vehicle Portfolio

A mechanical-engineering portfolio covering a student-founded defense startup, a gymnastics-equipment business, and CU Boulder engineering projects.

Why it surfaced

Worrell is designing a single unmanned vehicle intended to move from air to water and back again, with folding rotor arms, sealed avionics, and separate air and underwater propulsion. The project is still a design target awaiting physical validation, but the portfolio makes the engineering tradeoffs unusually concrete—and pairs them with the story of a 4.0 student who has already sold 500-plus backpacks through another company.
