It is a two wheel driven trolley with a couple of casters that sits underneath the proto board. With the addition of a couple of arms it should be good for table top challenge. And with a suite of ultrasonic sensors it should run nicely around a micromouse maze. I'm not sure how much will be working in two weeks, but I'll be bringing it along anyway.</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Anyone else have plans for things to show?</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Cheers</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>Richard Jones</DIV><DIV><BR class="khtml-block-placeholder"></DIV><DIV>PS.

The goal is to build a tabletop robot, that can drive around a Science Alive table without falling off the table, and locate a 2x2 inch box. Once it has found the box, it needs to push it down to one end of the table and into a shoebox. The eventual goal of this challenge is to get working robots, in the club, that could be used for 1 on 1 tabletop soccer.</SPAN></FONT></P><P style="margin: 0.0px 0.0px 16.0px 0.0px"><FONT class="Apple-style-span" face="Tahoma" size="4"><SPAN class="Apple-style-span" style="font-size: 16px;"><B>The challenge has 3 phases:</B></SPAN></FONT></P><OL><LI style="margin: 0.0px 0.0px 16.0px 0.0px"><FONT class="Apple-style-span" face="Tahoma" size="4"><SPAN class="Apple-style-span" style="font-size: 16px;">Stay on the table without falling off while turned on and moving.</SPAN></FONT></LI><LI style="margin: 0.0px 0.0px 16.0px 0.0px"><FONT class="Apple-style-span" face="Tahoma" size="4"><SPAN class="Apple-style-span" style="font-size: 16px;">Locate the box on the table and push it off without falling off yourself.</SPAN></FONT></LI><LI style="margin: 0.0px 0.0px 16.0px 0.0px"><FONT class="Apple-style-span" face="Tahoma" size="4"><SPAN class="Apple-style-span" style="font-size: 16px;">Locate the box, and push it into a shoe box (goal) at one end.</SPAN></FONT></LI></OL></BODY></HTML>
