Bio-Inspired Design and Additive Manufacturing Techniques for Aquatic Robot Development Based on the Locomotion of the Istiophorus (Sailfish)

Abstract

The goal of this project is to develop a robotic prototype capable of swimming at high speeds, intended for use un rescue operations and ocean research. The design focuses on replicating key characteristics of the sailfish's movement, particularly its dart-like shape during high-speed swimming, which is enhanced by its lack of scales, minimizing friction with water. The robotic prototype features degrees of freedom in its neck and fins, allowing vertical movement without human intervention, thereby providing added comfort and stability during deep-water rescue operations. Finally, the proposed bioinspired design of fish-morphology robots offered enhanced maneuverability, efficiency, adaptability, and stability for aquatic applications, while also presenting challenges that demand innovative solutions.
