Preview Improving swimming performance and flow sensing by incorporating passive mechanisms

Description:

Using a bio-inspired robot with multiple passive tails I demonstrate herein the relationship

between maneuverability and passive appendages. I found that the allowable rotation angle, relative

to the main body, of the passive tails corresponds to an increase in maneuverability. Using panel

method simulations I determined that the increase in maneuverability was directly related to the

change in hydrodynamic moment caused by modulating the circulation sign and location of the shed

vortex wake. The identi cation of this hydrodynamic bene t generalizes the results and applies to

a wide range of robots that utilize vortex shedding through tail 

apping or body undulations to

produce locomotion.
