“ort cost of 9.4 J/(kg·m). This sets a new speed record for soft robotic fish using body-caudal-fin (BCF) propulsion. To enable active control of the robot's orientation, the researchers developed a biomimetic swim bladder that operates through a liquid-to-gas phase transition. By regulating the local buoyancy of the robotic fish, the system generates a pitching moment and enables posture adjustment from −20° to 58°.”

- Tech Xplore — RoboticsSignalSoft Robotic Fish Combines High-Speed Swimming with 3D Maneuverability
Researchers from the Shenyang Institute of Automation have developed a soft robotic fish that can swim at high speeds and perform agile three-dimensional maneuvers. The design integrates a rigid–flexible coupled propulsion system with dynamic buoyancy regulation, inspired by biological mechanisms such as muscle-skeleton coordination and swim bladder function. The robotic fish achieves a maximum speed of 2.13 body lengths per second and can perform complex 3D movements like turning, ascending, and spiral ascent, offering a potential approach for high-performance underwater robots.
