[DampRobot]

We do use a larger sub-team model similar to what others have mentioned on this thread. We have Mechanical, Electrical, Software and Spirit subsections (Spirit handles essentially everything that one of the other sections doesn't do).

We really don't have mechanism specific sections like others have mentioned. Instead, we specialize based on skills, not based on which part of the robot needs to be worked on. For example, the robot was CADed this year by a small team, and parts were machined by another "sub team."

I've found that this type of division allows people to become very knowledgeable about their craft, and still feel like they really contributed. While one person might take pride in designing the robot, others would feel that they contributed by writing all of the software or machining all the parts.
