Autonomous Surface Vehicle (USV)

3D‑printed hull · Pixhawk 6C · Raspberry Pi 4 + Coral TPU · LoRa telemetry · LiFePO4 power · F9P GNSS

This project is a multi‑year build focused on reliable autonomous navigation on a large Norwegian lake. The USV integrates a 3D‑printed hull with epoxy coating, a Pixhawk‑based control stack, and a Raspberry Pi handling logic and AI inference. Power is provided by LiFePO4 packs, with LoRa‑based telemetry and mission updates.
