After the success of last year’s electronic depth controller, the team is pivoting to concentrate on developing new systems to capture and log more data on the submarine state during operation. The system will record the submarine’s depth, hull speed, attitude, acceleration, shaft RPM and control surface angle. The data will be collected by an onboard computer, which will be displayed to the pilot on an integrated display, and stored on an SD card for further review and analysis. Collecting and displaying this data will not only allow the pilot to perform better during the races, but will also allow us to test and validate new designs and optimizations, and help inform design decisions for future submarines. To integrate these new features, the previous year’s system will be re-built using a more powerful microcontroller, new printed circuit board, custom-made battery pack, additional bulkhead connectors and overhauled software.
