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.
