University of Washington assistant professor Kristi Morgansen has nearly perfected a robotic fish. The robot is designed to explore the sea in schools. The robotic fish communicate simple commands wirelessly while underwater. Morgansen states,
Underwater robots don’t need oxygen. The only reason they come up to the surface right now is for communication.
Mogansen has been working on these robots for five years. The robots use fins rather than a propeller as they are more aerodynamic and creat less air bubbles. The robots are about the size of a 10 lb salmon.
