Subsystems

Propulsion

Eight Blue Robotics T200 thrusters in a vectored configuration provide full 6-DOF movement. Custom ESC interface board manages thruster allocation.

Vision

Dual-camera system with YOLOv8 object detection running on NVIDIA Jetson. Forward camera for navigation, downward camera for bin tasks.

Controls

Cascaded PID controllers for depth, heading, and position hold. Extended Kalman Filter fuses IMU, depth, and camera data for state estimation.

Hull & Frame

Modular torpedo-style hull with 3D-printed PETG frame and acrylic pressure tubes. Quick-release end caps for rapid electronics access.
