What it does
This floating device gathers acoustic and visual data in fishing areas to assess the presence or absence of cetaceans. It aims to provide essential information to better understand and reduce the impact of fishing on marine mammals.
Your inspiration
This project was born from a double observation: the lack of reliable data on dolphin presence in fishing zones, and the many undocumented accidental bycatches. As a designer, I wanted to create a gentle solution, respectful of life, directly inspired by the animal itself in both form and material to develop a discreet, sensitive, and scientifically useful product.
How it works
The drone moves along the water surface following a pre-programmed route. At specific points, it stops to record underwater sounds using a hydrophone that can be submerged up to 15 meters deep. A submersible camera and a surface camera complete the collection of visual data. The system runs on batteries, supported by solar panels for power. This passive and non-intrusive operation is a respectful answer to the limitations of current devices, which are often too bulky, too noisy, or too expensive.
Design process
The project began with a research phase on the interactions between cetaceans and fishing activities. The drone concept was developed around a form inspired by the marine world and materials compatible with the saline environment. Next, a research phase was carried out to define the drone's functions, shape, and materials. Once these elements were established, the selected shape was further developed with user input. Finally, the design was modeled and a prototype was manufactured. Each component was individually tested before being integrated into a complete prototype, which continues to evolve through feedback and adjustments. The project has already been tested in real-world conditions and is supported by the company ROV Expert (technical and equipment sponsor), by ONE OCEAN a marine mammal protection association that welcomed me aboard their boat to carry out open-sea tests as well as by scientists specializing in cetacean research, who are interested in using it for their studies.
How it is different
The drone’s shape follows a biomorphic approach: its smooth lines and dorsal fin evoke the silhouette of a dolphin, helping it blend into the marine environment while optimizing hydrodynamics. Its surface is covered with a soft silicone layer that replicates the texture of dolphin skin, applying a biomimetic principle that allows for better hydrodynamic thrust. EchoBlue features a hydrophone capable of reaching depths of up to 15 meters an innovation that does not yet exist elsewhere.
Future plans
Next steps include improving the current prototype, optimizing the audio analysis system, and creating a data visualization interface for researchers. Eventually, I hope to share it with scientists to cover different sensitive marine areas and support cetacean conservation efforts.
