Overview

This MSc thesis project extends the work from the Holybro X500 water sampling drone to a heavy-lift Tarot T18 octocopter platform. The X500 project successfully demonstrated water sampling on the ground but revealed payload constraints (1kg limit) that prevented flight operations with the full sampling system. The T18 platform provides significantly higher payload capacity to accommodate the complete winch system, water containers, and advanced positioning using Pozyx UWB for GPS-denied environments like indoor labs and fjords.

Problem Statement

Traditional water sampling in Norwegian fjords requires boats and significant logistics. The previous X500 project demonstrated the core sampling functionality but could not achieve flight with the payload. This thesis aims to deliver a fully operational autonomous water sampling drone using the heavy-lift Tarot T18 frame with Pozyx UWB positioning for precise indoor/GPS-denied navigation.
