Robotic Fish 'Eva' Pioneers Underwater Research in Swiss Lake

ETH Zurich students have developed Eva, a robotic fish designed to study aquatic ecosystems without disturbing marine life, offering a revolutionary approach to ocean research.

Introduction:

In a groundbreaking initiative, mechanical engineering students at ETH Zurich are making significant strides in the field of underwater research. Despite being far from the ocean, these innovative students have developed a robotic fish named Eva, designed to explore and monitor aquatic ecosystems with minimal disruption. This cutting-edge technology, tested in the serene waters of Lake Zurich, could reshape the future of oceanography and biodiversity conservation.

Eva: The Robotic Fish Revolutionizing Aquatic Research

At first glance, Eva might appear to be just another fish gliding through the waters of Lake Zurich. However, this robotic fish is anything but ordinary. Designed by a team of students from ETH Zurich, Eva is the latest addition to the Surf-eDNA project, which has been in development for over two years. The project aims to create a fleet of robotic fish that can gather crucial data about aquatic ecosystems without disturbing the natural habitat.

Eva’s unique design is intentional. According to Denis Bauman, one of the lead developers at ETH Zurich, the robotic fish is crafted to resemble a real fish to ensure it blends seamlessly into its surroundings. "Eva looks like a fish in order to be as minimally invasive as possible within the ecosystem we are researching. Its design should not scare other fish," Bauman explained to CNN.

Innovative Features: What Makes Eva Stand Out?

Eva is equipped with advanced technology that allows it to perform a range of tasks vital for environmental research. One of its key features is a silicone tail that propels it through the water, mimicking the movement of a real fish. This not only aids in its camouflage but also allows it to navigate the lake's waters smoothly.

In addition to its realistic movement, Eva is fitted with a camera for underwater recording, a sonar system to detect and avoid obstacles, and a specialized filter designed to collect environmental DNA (eDNA). This DNA is then analyzed by scientists to determine which species inhabit the ecosystem, providing valuable insights into biodiversity and the health of the aquatic environment.

Expanding the Horizons of Ocean Research

The use of robotic fish like Eva represents a significant advancement in the field of oceanography. Traditionally, ocean research has relied on larger, more invasive technologies that can disturb marine life and potentially alter the data collected. However, with the development of devices like Eva, scientists can now conduct more accurate and less intrusive studies.

This approach is not limited to Switzerland. In California, a startup called Aquaai has developed similar fish-like drones that gather data on oxygen levels, salinity, and pH in various bodies of water. These innovations are proving to be invaluable tools for biologists and environmental scientists around the world.

The Future of Environmental Conservation

The potential impact of Eva and similar robotic fish on environmental conservation is profound. By providing a more accurate and less invasive method of studying marine ecosystems, these technologies could play a crucial role in protecting endangered species and preserving biodiversity. "We want to create a reliable tool for biologists. Maybe that way fewer species will become extinct or endangered," Bauman emphasized.

As the Surf-eDNA project continues to evolve, the team at ETH Zurich remains committed to refining their designs and expanding the capabilities of their robotic fish. With each new iteration, they move closer to creating a fleet of autonomous underwater drones that could revolutionize how we understand and protect our planet's aquatic environments.

Conclusion: A New Era in Aquatic Exploration

Eva, the robotic fish developed by ETH Zurich, is more than just a technological marvel; it represents a new frontier in environmental research. By mimicking the appearance and behavior of real fish, Eva can gather crucial data without disrupting the ecosystems it studies. This innovative approach has the potential to transform our understanding of aquatic life and contribute to the preservation of biodiversity worldwide. As advancements in this field continue, the work of these students may well inspire a new era in the exploration and conservation of our planet's most precious resources.
