The Refactoring

This year has primarily been a software year for Team SubjuGator, as our excellent mechanical and electrical systems which were completely redesigned last year have proved to be very reliable and extensible. We began the year with a large scale refactoring that eventually reached every worker process that runs on the sub. Our communications framework, DDS, allowed us to keep the sub operational at all points during the refactoring, because though workers were changing sometimes dramatically on t

Calibrations and tuning

After a few small thruster leakage setbacks, we’ve officially completed all of the calibration and tuning procedures for SubjuGator 7. We’re using a new nonlinear controller this year, which is achieving outstanding transient performance and steady-state tracking errors over last year’s PD. We’re able to successfully move to desired waypoints and orientations using our real-time C3 continuous trajectory generator. Here is a photo of the controller tuning process at the po
