“Manta Ray Drones Are Coming”: New Underwater Robots to Glide in Swarms With Unprecedented Military and Scientific Precision

In the realm of technological advancements, nature continues to be a profound source of inspiration. The latest innovation in underwater technology draws from the graceful movements of manta rays. These majestic creatures exhibit a unique ability to glide effortlessly through the ocean, making them an ideal model for developing cutting-edge underwater drones. This article delves into the fascinating intersection of biology and technology, where scientists aim to harness the hydrodynamic secrets of manta rays to enhance underwater vehicle performance.

Exploring the Efficiency of Manta Ray Formations

Scientists from Northwestern Polytechnical University have embarked on a pioneering study to understand how manta rays’ group formations impact swimming efficiency. By observing real-life manta ray groupings, researchers created simulations to explore three primary configurations: linear tandem, V-like triangle, and inverted triangle formations. These formations provide insights into how manta rays achieve their remarkable efficiency in the water.

The research revealed that the tandem formation was particularly beneficial for the manta ray positioned in the middle. This individual gained a propulsion boost from the flow generated by the leading ray, significantly enhancing its maneuverability. Conversely, the triangular formations, while common in nature, did not offer the same hydrodynamic advantages. This discrepancy suggests that factors beyond energy efficiency, such as social interactions, might influence manta rays’ preference for these formations.
