RoboSub Team

RoboSub is R3’s most advanced project to date, the primary objective of which is to design and manufacture a submarine capable of participating at a high level in the RoboSub competition.

Felix on a Bench
The sub, or Felix as we call it, features some of the most involved design work ever completed for an R3 project. Felix comes from a common design philosophy within the robosub community; a holonomic thruster configuration for yaw manuevers and translations in the XY plane and, coupled Z facing thrusters for upward translations as well as roll and pitch maneuvers.

The large aluminum wings serve two purposes: to hold the thrusters in place and to provide drag during roll and pitch maneuvers. A lot of time was devoted to designing a small, symmetric, and maneuverable submarine.

RoboSub Team at Competition
Felix’s control system is one of the most advanced that R3 has developed. Felix runs its navigation and object detection on a Nvidia Jetson TX2, paired with STM32 microcontrollers for high speed I/O for sensor data collection and thruster control. The microcontrollers are mounted onto custom shield boards with the power, signal processing, and low-level communication hardware.

Felix’s control system also features a very sophisticated control algorithm, responsible for handling tasks such as generating inputs for the cascaded PID to output to the thrusters or running the YOLO V3 neural network which we trained to detect the gate, buoys, and other competitions objectives.

We are very happy to announce that all of our work went into achieving a score of 18th in our first year at the RoboNation RoboSub competition.
