Despite freezing rain and wind, everyone showed up. Our four-member team, TachyAstroach, kicked off the mission.</p>https://career.purticra.icu/projects/tachyastroach/Sun, 15 Feb 2026 00:00:00 +0000hlyu68@gatech.edu (Hongyi Lyu)https://career.purticra.icu/projects/tachyastroach/<div class="lead text-neutral-500 dark:text-neutral-400 !mb-9 text-xl"> A mother-daughter rover system designed for extraterrestrial exploration built from raw materials in 36 hours at the Georgia Tech IEEE Robotech Hackathon. </div> <a class="!rounded-md bg-primary-600 px-4 py-2 !text-neutral !no-underline hover:!bg-primary-500 dark:bg-primary-800 dark:hover:!bg-primary-700" href="https://devpost.com/software/moonline" target="_blank" role="button"> View on Devpost </a> <h2 class="relative group">Overview <div id="overview" class="anchor"></div> <span class="absolute top-0 w-6 transition-opacity opacity-0 -start-6 not-prose group-hover:opacity-100 select-none"> <a class="text-primary-300 dark:text-neutral-700 !no-underline" href="#overview" aria-label="Anchor">#</a> </span> </h2> <p>TachyAstroach: MoonLine is a mother-daughter rover system where the primary unit launches a secondary sub-unit, with both coordinated wirelessly through custom actuation mechanisms. The project was completed during a 36-hour intensive build at the <strong>GT IEEE Robotech Hackathon</strong>, transforming raw materials into a functioning extraterrestrial rover prototype.</p>
