Autonomous Robotic Jellyfish Could Patrol the Seas
Added Mar 28, 2013 | Rate View top rated
Virginia Tech researchers have introduced an autonomous robotic jellyfish the size and weight of a grown man - 5 foot 7 inches in length and weighing 170 pounds - as part of a U.S. Navy-funded project. This prototype robot is nicknamed Cyro, and is a larger version of a robotic jellyfish named RoboJelly that was introduced in 2012. This has been a team effort, with University of Texas at Dallas handling nanotechnology-based actuators and sensors, Providence College handling biological studies, UCLA handling electrostatic and optical sensing/controls, and Stanford University overseeing chemical and pressure sensing. Virginia Tech has focused on building the jellyfish body models, integrating fluid mechanics, and developing control systems. In the future, a robot jellyfish's job could include conducting military surveillance, cleaning oil spills, or monitoring the environment.

I wonder if the change in salinity due to depth in the ocean can be used as a perpetual power source for the low-energy jellyfish robot? Saltwater salinity at depth: http://www.wind­ows2universe.org­/earth/Water/sal­inity_depth.html Researcher that knows something about saltwater batteries: http://www.smar­tplanet.com/blog­/science-scope/video-batteries-made-of-salt-water-last-10x-longer/10976 The concept being that periodically the jellyfish robot changes depth to recharge its' batteries.
