“…Xia et al applied highly flexible origami technology to fish tails, significantly improving energy efficiency. The experimental results show that the robotic fishing gear has good straight swimming direction and turning ability [5]. Zhu et al designed an underwater robot that mimics the swimming of a turtle and analyzed the force acting on the robot during operation in water.…”

All along, human exploration of the ocean has never stopped, and bionic fish robots have been produced. Currently, bionic fish have been used in a range of fields, including underwater archaeology, water quality monitoring, and other fields, because of their camouflage and flexibility. The bionic fish also can perform observation, reconnaissance, and other jobs, reduce battle risks, and play a crucial role in contemporary military tasks. It is increasingly being implemented in the military sphere. The efficacy of the bionic fish’s tail mechanism in terms of swimming and reconnaissance is crucial to the design of the fish. However, multiple servo joints are frequently used in the current bionic fishtail system, which increases the likelihood of failure. This research suggests a fishtail design strategy based on the transmission mechanism to operate more steadily. After analyzing the existing bionic fish mechanical structures, research proposes the schemes of living in three mechanical structures. By combining the actual fish body size, the comprehensive modeling design was carried out using Solid Work software, and the motion performance analysis of the mechanism was analyzed by Adams software. The experimental results provide a theoretical and reference for the actual design of bionic robotic fish.

“…[ 7,8 ] These features ensure fewer repairs and maintenance to the wings; essential qualities in cluttered deep‐sea environments. Most of the present literature regards the use of soft robotic actuation for undulatory propulsion in marine applications, [ 9–16 ] whereas this work focuses on using soft wings to maximize efficiency in UUVs. Here, the design and manufacturing process of a wing constituted of a soft silicone actuator and a rigid leading edge are explored.…”

Actuators based on soft elastomers offer significant advantages to the field of robotics, providing greater adaptability, improving collision resilience, and enabling shape‐morphing. Thus, soft fluidic actuators have seen an expansion in their fields of application. Closed‐cycle hydraulic systems are pressure agnostic, enabling their deployment in extremely high‐pressure conditions, such as deep‐sea environments. However, soft actuators have not been widely adopted on unmanned underwater vehicle control surfaces for deep‐sea exploration due to their unpredictable hydrodynamic behavior when camber‐morphing is applied. This study presents the design and characterization of a soft wing and investigates its feasibility for integration into an underwater glider. It is found that the morphing wing enables the glider to adjust the lift‐to‐drag ratio to adapt to different flow conditions. At the operational angle of attack of 12.5°, the lift‐to‐drag ratio ranges from −70% to +10% compared to a rigid version. Furthermore, it reduces the need for internal moving parts and increases maneuverability. The findings lay the groundwork for the real‐world deployment of soft robotic principles capable of outperforming existing rigid systems. With the herein‐described methods, soft morphing capabilities can be enabled on other vehicles.
