Re: motor stall current vs Victor ratings
We power the whole electrical system through a single 120A breaker (which can really do at least 160A for a minute or so), then each motor circuit is further protected by its own 20A, 30A, or 40A snap-action auto resetting breaker. The 40A variety can actually handle about 70A for a few seconds.
FIRST will publish an electrical system diagram for 2007 (and component datasheets) sometime shortly after Jan. 6, which will make all this a little clearer.
EDIT: Of course, FIRST tweaks the rules a little every year. We have no idea what changes we may see this time around. However, it is typical of our Game Design Committee to make rules that encourage robots built to perform a scoring function that usually requires handling or at least controlling a game piece. The high-power traction systems typical of BBIQ are generally not required for success in the FRC.

I believe in intuition and inspiration. Imagination is more important than knowledge. For knowledge is limited, whereas imagination embraces the entire world, stimulating progress, giving birth to evolution. It is, strictly speaking, a real factor in scientific research.
