Undulating Fin Propels Robotic Fish
     







Modeled after the Black Ghost Knifefish using computational fluid
dynamics simulation,
Researchers at Northwestern University are

exploring an interesting form of locomotion that could be useful for
underwater robotic propulsion.
Using precise control of counter-propagating waves along undulating fins
just like the fish of the Amazon Basin rivers, the robot can control
movement in 3d space.
