A UNIQUE AND SCALABLE
INNOVATION:
To date, no other autonomous floating
device integrates a hydrophone that
descends to a depth of 15m into such a
compact bio-inspired structure. It is a
unique solution that is mobile,
environmentally friendly, and
accessible. It allows for close proximity
to cetaceans without disturbing them,
while generating valuable data for
research and biodiversity preservation.
This project embodies a strong desire:
to reconcile design, technology, and
ethics, to promote better coexistence
between humans and the marine
environment.
Currently, EchoBlue is a first functional
prototype, used in manual mode. It
already collects acoustic and visual
data on the surface and underwater
thanks to its onboard sensors.
In the near future, the goal is to make it
fully autonomous: programmed
navigation, stops at listening points,
automatic sensor deployment, real-
time data transmission, etc, while
maintaining a minimal ecological
footprint.
Dimensions:
99 cm long
Onboard systems: Hydrophone (15m long),
surface camera
underwater camera
Power supply:
Solar panels integrated
into the surface. These recharge the internal
batteries, extending the vehicle's autonomy
during multi-day sea missions.
Project History: EchoBlue was designed as
part of a design graduation project, with the
aim of combining technological innovation,
conservation, and sustainable design. The
design process was carried out in
collaboration with marine experts and field
users. The project adopts a participatory
approach, soliciting feedback from biologists,
fishermen, engineers and citizens to improve
its functionality and relevance.
EchoBlue is currently supported by two
sponsors: ROV Expert, a company specialising
in underwater exploration and robotics, which
donated electronic components, and One
Ocean, an initiative committed to ocean
conservation, which is supporting the project
by offering me the opportunity to conduct
tests in the open sea with cetaceans.
Applications and potential:
EchoBlue can be used by many stakeholders:
Scientists:
Non-intrusive
observation of marine
wildlife
Authorities/NGOs: Passive monitoring of
sensitive areas
Educational:
Awareness-raising and
environmental education
“In the long term, the device could contribute
to acoustic mapping, noise pollution analysis,
and the active protection of marine
biodiversity, said developer Célia Granjeaud.
“EchoBlue is not just a technical object: it is a
living, evolving platform, deeply rooted in a
responsible and committed design
approach.”
