We ran the Table Top Challege Levels 2 and 3. Level 2 means: build a robot that moves around on a table top without falling off, while being able to locate and push blocks off the table. Level 3 is similar, but push the blocks into designated goals. Pete's new Ridgesoft Intellibrain-powered robot attempted level 3, though it did not quite succeed.
Rules for the Table Top Challenge are now online.
