Description

<p>In recent years, ocean research has become increasingly important, and many underwater robots have been developed. In this study, we focus on jellyfish swimming because of its high mobility efficiency and developed a jellyfish-like soft robot that can operate underwater. Jellyfish's flexible bell margin is critical for its efficient swimming. Thus, the purpose of this study was to attach an actively drivable flap to the tip of the robot and assess the effect of the flap. As a result, we confirmed that the robot was benefiting from PER. We also obtained data suggesting that driving the flap enhanced the passive energy recapture (PER). However, there was also data indicating that the flap was inhibiting the propulsive force at the latter phase of the cycle.</p>
