Oh, the next meeting for Robotics Society of Southern California will be on Aug 14. I plan on busting out my wallet and paying the $12 membership fee. I suspect Fred will be doing the same. They're supposed to have mini sumo competitions at the end of each meeting, but Fred told me last time they didn't have one. Guess I'll have to ask around to see what's up. Since, Fred and I want to build our own custom mini sumo.
