LEVITATE

—Acronym says it all: The Lunar Exploration Vehicle for Intraplanetary Transport and Terrestrial Expansion. An enormous project, but a good time. The EMA senior design spans two semesters; the first develops an idea into a consumer product, while the second tasks us to design an airplane, submarine, or spaceship. Last semester I developed BoomAlert, a […]
