Robot Fish Powered By Artificial Muscle

x2agent points to this article on yomiuri.com, excerpting: "Start-up companies in Osaka Prefecture have developed what is believed to be the world's first fish robot with artificial muscles capable of reproducing the natural movements of real fish." z2agent writes "I found this article while I was searching for something about robots and thought it was interesting. I was wondering where do you draw the line between 'robots' and 'remote controlled car with a Skil saw mounted to the front' like in Battle Bots?"

just different kinds of artificial muscles by js7a · 2002-12-25 20:16 · Score: 2, Interesting

From the article:
The artificial muscle, or polymer molecule actuator, comprises a plastic [resin that expands and contracts in response to electric signals] plate containing water sandwiched between two capped electrodes.

That's just entirely different than what MIT is doing, as MIT is actually using hydrogel polymer techniques, and these fish people just have some new kind of electrical plastic.
