Hi SK
just a quick question what do you use for a power source and what's your power management dealt with. I'm in the process of designing a power management PCB to regulate a 6 cell lipo down to 15V. What sort of current does you bot draw. Also are you still using the CM2 or have you moved on to another type of controller. If your interested I use a gumstix.

Ok, I´ll try to answer those questions to the best of my knowledge, I´m more at home at the software side of things, so bear with me 
We´re using 2 LiPo Packs in the feet, each having 7.4V/1300 mAh. Together those provide 14.8V to the servos. They´re also supplying power to a custom built power management PCB which in turn powers the PC104 board in the back (Geode LX 500Mhz) and the microcontroller, which is no CM-2, but has a Renesas SH2 processor.
You might also want to look at the Team Description Paper for RoboCup 2007, if you haven´t already:

Note that some data there is outdated though. There used to be 3 LiPos on the robot for example, this was changed to 2 as described above.
/edit: Not sure about max and average current draw right now, gotta ask those in the know sometime later.
