For the 2019-20 season, the Oregon Tech Unmanned Systems (O.T.U.S.) team was able to compete in the RoboSub competition and apply a variety of improvements to every aspect of our project, such as the development process, mechanical and software systems of the robot, and our future engineering prospects. This would not have been possible without the support from Oregon Space Grant and their funding to give us access to equipment, labs, and time to work on the Robosub during such difficult times. We had planned to work on our Robosub in person, but due to the current COVID-19 pandemic, we had to figure out strategies to work virtually and in person for limited amounts of time. Our three-man team along with our mentor, Don Lee, worked during this time to ensure we had a system that would allow us to compete in the RoboSub competition, that was greatly improved from last year, with foundation for improvement and further advancements on a new robosub frame. On the mechanical side, these improvements include a more compact electronics housing integrated with natural water cooling, an integrated main power distribution board, and more versatile mounting options for peripheral electronics and sensors. On the software side, the improvements consisted of a completely rewritten system, modularizable sensors and hardpoints, virtual environments for task simulation and AI development, as well as extensive documentation. There is also a framework being developed for our next advancements, including the amphibious designs of our future ‘Rover Sub’.
