Using electrolocation, as it's known, is common in fish, particularly sharks, which <A href="http://www.pelagic.org/overview/articles/sixsense.html">detect electric fields</A> better than any other animal. Think of it like sonar with electricity. <BR /> </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://blog.wired.com/wiredscience/2008/06/video-robotic-h.html"><P>Joshua Smith, an Intel researcher working on the project, said that electrolocation only provides coarse data about the shape of objects, but that this actually worked very well for grasping tasks. Using the technique is one means by which his team is trying to give robots what they call "Pre Touch," a sense that has a longer range than touch but a shorter range than vision. Perhaps a catchier name would have been <EM>the sixth sense</EM>. </P></blockquote><div style="height: 2px; font-size: 2px; background: #dcdcdc; border-bottom: solid 1px #f5f5f5; margin: 2px 4px;"></div><blockquote style="text-align: left; padding: 0px 8px; margin: 4px 0px 8px 0px; background: transparent; border: none;" cite="http://blog.wired.com/wiredscience/2008/06/video-robotic-h.html"><div align="center"><embed src="http://www.youtube.com/v/DB3pNtZvlRA" height="329" width="400" wmode="opaque" quality="high" type="application/x-shockwave-flash"></embed></div></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/1C06E4D6-88D9-4FAE-948D-9161C878DF36/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>
