Some of my bots from the last few years.  I am getting ready for Maker Faire in Flushing Queens on September 29-30.  As I always tell my students, 'Robots rarely do what you want them to; I am happy when they do what I tell them to do."  Last night at the robot club meeting, a newcomer picked up a 'PIC-Bot' and asked what it did.  'Probably nothing,' but I was surprised to see that it knew enough to stay on the tabletop.  Robots are a rich context for teaching math and science but they are also really cool and often do unexpected things.
