Area of Science:

  • Robotics and Biomechanics

Background:

  • Natural fish exhibit smooth undulation with flexible tails for efficient swimming.
  • Fish adapt swimming states by altering body stiffness, inspiring robotic fish design.

Purpose of the Study:

  • To explore a stiffness optimization scheme for a novel elastic robotic fish tail.
  • To improve the swimming performance of robotic fish through tail stiffness modulation.

Main Methods:

  • Developed a dynamic model using the Lagrangian dynamic method and a pseudo-rigid-body model for flexible joints.
  • Analyzed hydrodynamics using the Morison equation and quasi-steady wing theory.
  • Employed parameter identification to determine unknown hydrodynamic parameters.

Main Results:

  • Identified simulation speeds closely matched experimental data across various stiffness values.
  • Optimal joint stiffness distribution reduces stiffness from front to rear.
  • Achieved optimal swimming speed of 0.3 body lengths per second at 2.5 Hz, exceeding rigid tail performance.

Conclusions:

  • A flexible, stiffness-optimized tail significantly enhances robotic fish swimming performance.
  • The study provides a validated dynamic model for further robotic fish research and development.
