General overview

Our strategy for participating in RobotSub for the first time is "basics first; software over hardware." BRACU Duburi's broad plan for RoboSub 2022 is to focus on executing the most basic activities first with a simple design; only after refining the basics have we added additional functionality (and complexity) to our designs to enable it to complete the more sophisticated duties of the RoboSub course. Furthermore, we overcome our material and logistics constraints by selecting only the bare minimum of gear. To make up for that, we've spent a lot of effort and time into developing a solid computer vision and software control system.
