Designing a frame for an underwater drone isn’t just about functionality—it requires materials that can endure pressure, impact, and moisture without compromise. That’s exactly what made PETG filament the material of choice for this ambitious student engineering project.
The Challenge
Develop a robust, water-resistant drone chassis capable of navigating underwater environments, while protecting sensitive electronics and ensuring stable performance.
The Solution
- PETG filament: Excellent impact resistance and long-term durability.
- Waterproof aluminum tube: Safely encloses and protects all onboard electronics.
- 5 motors enable precise and responsive underwater maneuvering.
- Raspberry Pi & Pixhawk for control and navigation.
- FPV camera & LED lighting support real-time exploration in low-visibility conditions.
With thoughtful engineering and the right materials, this underwater drone delivers stability, control, and resilience beneath the surface.
This impressive prototype was developed as a diploma project by Marian Spörr and Paul Schiener from HTL Anichstraße, focusing on Electrical Engineering & Process Informatics.
A perfect showcase of applied technology and creative problem-solving in the field of robotics and automation.
