Data-collecting robot fish. Students at ETH Zürich designed a robotic fish to help marine biologists study ocean life. Eve mimics real fish movements, blending into coral reefs without disturbing marine ecosystems. With a silicone tail, Eve glides silently through the water while capturing high-resolution footage. Equipped with advanced sensors and navigation, Eve avoids obstacles and maps its surroundings in real time. A built-in filtration system collects environmental DNA (eDNA), helping scientists identify species without direct contact. This cutting-edge tech makes marine research more efficient and less invasive. Would you trust a robot fish to help protect the ocean? Learn more at surf.ethz.ch
