Hydraulic Autonomous Soft Robotic Fish for 3D Swimming

  title={Hydraulic Autonomous Soft Robotic Fish for 3D Swimming},
  author={Robert K. Katzschmann and Andrew D. Marchese and Daniela Rus},
This work presents an autonomous soft-bodied robotic fish that is hydraulically actuated and capable of sustained swimming in three dimensions. The design of a fish-like soft body has been extended to deform under hydraulic instead of pneumatic power. Moreover, a new closed-circuit drive system that uses water as a transmission fluid is used to actuate the soft body. Circulation of water through internal body channels provides control over the fish’s caudal fin propulsion and yaw motion. A new…

Passive robotic models of propulsion by the bodies and caudal fins of fish.
This model demonstrates an interesting resonance phenomenon in which swimming speed varies with foil length in an oscillatory manner, and small changes in length can have dramatic effects on swimming speed, and this relationship changes with flexural stiffness of the swimming foil.
