Design and Depiction of 3D Printed Robotic Fish

Recently, fish robots have been widely used in various applications such as ocean exploration, military operations, and the preservation of marine circumstances. It requires high-performance autonomous underwater vehicles, especially for propulsion, and has great benefits with flexible invariability. Our paper focuses on the theoretical framework of the design, 3D modeling, and vertical and horizontal locomotion control of the robotic fish. The physical design of the robotic fish is obtained by trying to mimic the external anatomical features of a living fish. The structural design should mimic the fish's body structure. The body of a robotic fish should be compact and accommodate all sensors, actuators, and motors. By managing the amount of water inside the ballast tank, the fish can attain vertical motion and depth control.
