In a world where technology draws inspiration from nature, robotic fish emerge as the latest innovation reshaping ocean exploration. Researchers worldwide are developing these aquatic automatons, citing their affordability, ease of use, and minimal disruption to sea life compared to traditional remotely operated vehicles (ROVs).
A recent review of robotic fish technology highlights its promising advancements, indicating only a few technical hurdles remain before a potential revolution in underwater exploration. These prototype fish, equipped with video cameras and sensors, traverse the seas, documenting marine life and gathering crucial data on depth, temperature, and acidity.
According to marine engineer Weicheng Cui, robotic fish have the potential to outperform existing ROVs in various tasks. Their small size, stealthy movement, and resemblance to real fish make them ideal for observing sensitive species and exploring intricate underwater environments like coral reefs and undersea caves.
However, current models face limitations, particularly in range and endurance. To render modern ROVs obsolete, robotic fish require autonomous charging stations for extended operations. Cui envisions a future where fleets of these fish collaborate on deep-sea missions, docking at underwater stations powered by renewable energy sources.
Despite the potential benefits, some experts remain cautious about fully embracing robotic fish. Paul Clarkson from the Monterey Bay Aquarium acknowledges the indispensable role of ROVs in research but suggests exploring new innovations amidst growing environmental challenges.
As the threats of climate change, habitat destruction, and pollution loom large, the development of robotic fish offers a glimpse into the future of ocean exploration. While the transition from ROVs to robotic fish may pose challenges, their potential to enhance our understanding of the changing marine ecosystem is undeniable.
