Holy smokeado!
If there's a game that has some seriously harsh terrain, I know who I'm calling.
It looked like you were using a mass of hobby-class R/C car batteries to power the robot. How do they hold up? (I know those 3300 cells do well in R/C cars, but I think this wasn't their intended use.
)
And, I guess the question on everyone's minds...how did you interface Wifi with the RC?
<tangent>With 802.11x hardware being just this side of dirt cheap, could this be the next level of FIRST robot communication? I mean, the current IFI equipment is primo stuff, just limited by the number of channels in the 900 mhz spectrum. I'm sure there are plenty of pitfalls, but the ability to send all of this information this way could make it easier for FIRST to add more fields at the Championship, or--dare I say it lest Dave get ideas--more robots on the field.<tangent>
Did somebody say white paper?
