This project is in collaboration with Linnaeus University and Combitech AB, and part of the research arena WARA-PS, focuses on enhancing autonomous vehicles and their societal integration. By incorporating advanced autonomous systems, sensors, and communication tools across land, air, and sea, the aim is to reduce human intervention in hazardous environments. Current watercrafts are technically equipped but suffer from low availability and high manufacturing costs. The project proposes a modular and adaptable design, allowing 3D-printing of watercraft parts to customize for specific needs. The goal is to develop a 3D-printed watercraft applicable in research, rescue missions, and societal uses. The resulting nearly full-scale watercraft features a functioning drivetrain and detailed manufacturing documentation, highlighting waterproofing and customizable technical components. Extensive testing ensured its functionality and performance under various conditions.
