Full Electrical Stack for AUV5.0

End-to-end electrical architecture of a new autonomous underwater vehicle.

Overview

AUV 5.0 is the newest iteration of Bumblebee’s Autonomous Underwater Vehicle (AUV) to increase our AUV’s capabilities and efficiency in completing task for competitions. This is also a follow up from the MiniAUV project that we developed for Robosub 2025, where we tested new sensors, peripherals and thruster configurations.

I am currently working with my team on AUV 5.0’s full electrical stack to upgrade the overall power and communications architecture significantly.

What we are working on:

AUV 5.0 Elec Stack Side View

AUV 5.0 Electrical Stack (WIP)

  • Power distribution and protection
  • VESC, Sensors, Actuators, Compute Stack interfacing
  • Firmware for all MCUs on the various PCBs
  • Communications
  • Integration, and bring-up

PCBs

These are my latest two PCBs for AUV 5.0, which are still in development and testing stages:

AUV 5.0 Sensors Board

4 Layer PCB (Polygons shelved) - Sensors Board

AUV 5.0 Lights Controls Board

4 Layer PCB (Polygons shelved) - Lights Control Board

You will need to wait for a while for the full writeup!

Well, the developments are exciting and so is reveal of this project’s performance during the competition itself!
