A connected central electric drive unit transmits the force to a bevel gear wheel and then to eight spur gears in sequence. These gears power eight shafts, each of which activates a crank; these in turn move the jellyfish's eight tentacles. Each tentacle is designed as a structure with Fin Ray Effect®- a construction derived from the functional anatomy of a fish's fin. The actual structure consists of two alternating tension and pressure flanks movably connected by ribs. If a flank is subjected to pressure, the geometrical structure automatically bendsin the direction of the applied force. Together, the tentacles produce a peristaltic forward motion similar to that of their biological model.</BLOCKQUOTE></blockquote></div><div style="margin: 0px 6px 6px 4px;"><table style="font-size: 11px;border-spacing: 0px;padding: 0px;" cellpadding="0" cellspacing="0" width="100%"><tr><td style="background:transparent;border-width:0px;padding:0px;">&nbsp;</td><td align="right" style="background:transparent;border-width:0px;padding:0px;width:107px" width="107"><a href="http://clipmarks.com/share/744E9CA8-5A5B-495C-8A4E-27407CB7DC2B/blog/" title="blog or email this clip"><img src="http://content8.clipmarks.com/images/c2b-foot.png" border="0" alt="blog it" width="107" height="17" style="border-width:0px;padding:0px;margin:0px;" /></a></td></tr></table></div></div>
