Team Unsinkable is an independent, student-led team representing Embry-Riddle Aeronautical University, composed entirely of undergraduate students of varying majors. Our mission is to deliver a positive working environment where students can gain valuable experience working as a team in order to solve difficult real-life problems while utilizing the engineering process. Our team consists of 3 sub-teams; electrical, mechanical, and software. We are excited to present our new platform, Nautilus, and its partner, Cuttlefish, for the RoboSub 2021 Virtual Competition!
