The concept of biomimicry, where humans mimic nature's designs and processes to solve complex problems, has paved the way for groundbreaking advancements in various fields. One such remarkable application is in the realm of underwater robotics, where Boston Engineering engineers have looked to the natural world for solutions to create highly maneuverable and efficient underwater autonomous vehicles.
Biomimicry involves learning from biology and mimicking nature's perfected designs and processes, which have evolved over millions of years. This approach has led to innovations that have revolutionized various industries. Examples include the silent flight of owls inspiring quieter aircraft and the skunk's odorant secretion inspiring the safety feature of adding scent to odorless natural gas.
The Underwater Challenge: One of the significant challenges in underwater robotics is creating machines that are highly maneuverable and energy-efficient, capable of performing complex tasks in challenging underwater environments. Traditional remotely operated vehicles (ROVs) excel in linear movements but struggle with agility and versatility.
The Fish-Inspired Solution: The robotics team at Boston Engineering turned to nature for inspiration. They selected the tuna as their muse, a fish known for its remarkable speed, maneuverability, and efficiency. The tuna's unique swimming motion, where only the rear third of the fish moves while the front remains focused on the target, became a pivotal design element.
Reverse Engineering Nature: To replicate the tuna's motion and efficiency, the team embarked on a journey of reverse engineering. They meticulously measured and analyzed the fish's physical attributes, from its skeletal structure to its muscles. This detailed understanding allowed them to create an exact replica of the fish's physical form, a crucial step in the biomimicry process.
Digital Twin and Evolution: Mimicking the physical form was just the beginning. The team also sought to replicate the fish's motion. They used a genetic algorithm and real-time measurements to evolve the fish's swim profile continually. By comparing the fish's performance with various swim profiles, they selected the most efficient ones, mimicking the process of natural selection. Learn More about this and other digital solutions
First Prototypes and Field Trials: The team's dedication and innovation bore fruit with the successful creation of the first prototypes of their biomimetic fish. These robots displayed impressive maneuverability and efficiency in the water, a testament to the power of biomimicry. Real-world field trials with the United States Navy demonstrated the fish's capabilities in inspecting underwater assets, showcasing its potential in critical applications.
Future Possibilities: Boston Engineering's robotics team envisions swarms of interconnected robots working together to patrol and protect our shores, borders, and warfighters. This vision highlights the potential of biomimicry in creating innovative solutions to those and other complex challenges.
