Honestly, I always thought the same thing you do. We have about 20 kids I would say...and we really all do robot related things. Obvoiusly, some people do a lot more work than others. Some come, and don't even get that much work done. However, in our facility (Ex-Cell-O) we need a "buddy" when we use a tool to cut a part (good safety procedure anyway) so it always is helpful to have extra people around to be buddies.
In general, I guess people choose if they want to design, or just build parts... or mainly strategize... but we honestly don't do very much fundraising or any of the spirit stuff.
Maybe we should...
