As stated above you could strap a computer on the robot but not only does a CUDA processor pull massive power, upwards of 400 watts if I remember correctly; and as for getting useful information out of the mother bored would be a challenge. Also probability of a mother bored not cracking is slim to none. Although I'm unfamiliar with this new camera module I think that may be the way to do it. I'm planning on researching it in depth as soon as I can.

I was aware of the power draw. I'm not saying we should strap on a few 295GTX's in SLI and go from there, but use a smaller processor which draws 100-150 watts max. A low-power dual-core CPU would simply handle off-loading tasks to the GPU and handling I/O to the memory banks and Crio. My old-model 8800 GTS would easily handle the job, and it tops out at ~120 watts.
I guess we'd also need a way to keep a powersupply which can survive even in extreme low voltage situations and keep the current going to the system. As you could witness by watching the DS during a match this year, simply taxing 2 CIM's to stall drops the voltage to 8ish volts from a full battery, more if you have other systems or a damaged battery (as I witnessed when we got down to 5, then witnessed some fluid around it after the match. It was retired).
