A bionic neural network for fish-robot locomotion
Journal of Bionic Engineering, 2006A bionic neural network for fish-robot locomotion is presented. The bionic neural network inspired from fish neural network consists of one high level controller and one chain of central pattern generators (CPGs). Each CPG contains a nonlinear neural Zhang oscillator which shows properties similar to sine-cosine model.

An Untethered Bionic Robotic Fish Using SMA Actuators
2020 IEEE International Conference on Mechatronics and Automation (ICMA), 2020The authors develop a bionic robotic fish that has a soft tail using smart material as an actuator. Two sets of shape memory alloy (SMA) wires are stitched inside of the soft tail, which would let the tail bend in both sides. The designed structure is expected to gain the ability to imitate the swimming posture of a real fish in the water to swim ...

Water Entry Locomotion Strategy for a Stranding Bionic Robotic Fish
Journal of Field RoboticsAbstractSimilar to other underwater robots, bionic robotic fish face entrapment risks when stranded due to wave action or water level drop. In this paper, we propose a locomotion strategy for a whale shark‐inspired robotic fish, enabling it to autonomously return to aquatic environments after being stranded on land.

Fast-Swimming Soft Robotic Fish Actuated by Bionic Muscle
Soft RoboticsSoft underwater swimming robots actuated by smart materials have unique advantages in exploring the ocean, such as low noise, high flexibility, and friendly environment interaction ability. However, most of them typically exhibit limited swimming speed and flexibility due to the inherent characteristics of soft actuation materials. The actuation method
