Maker Faire Bay Area 2009
e pur se muove (and yet it moves)

Location: Expo Hall 207

We have sumo robots that wrestle, taildraggers work their way through a maze, and trebuchets launch a bean at a target. Our interest is to have youth experience making two motors work together to accomplish a goal and talk about the physics of what makes a trebuchet work.
