This project is a continuation of the successful collaboration enjoyed between Poland, Germany and Portugal in the first SABUVIS project. In this first iteration, three different Biomimetic Underwater Vehicles (BUVs) were constructed with the resulting conclusion that BUVs can be designed with varying degrees of similarity with living organisms. Some of the identified benefits are that undulating propulsion consumes less electrical energy than conventional propulsion systems utilising screw based propellers, and different hydroacoustic signatures are produced with a corresponding lower noise level.
