Multiple cRIO's-Power and Communication

[edthetoad]

Our team has decided that we will be using a second computer on our robot because we are unable to run complicated drive code and vision processing at the same time. When we do this our code does not always deploy, freezes up, and has bad performance, and we have only just started working on drive. I have looked into using a second FRC cRIO (old version). We would see that 2 cRIO's are legal for the robot but we are wondering what the applicable cost of the cRIO is. We also are going to power the cRIO with a DC-DC voltage converter from 12 to 24 volts. We also try to communicate between the two of them using UDP. Is there anything we should be aware of if we attempt this? Do you know of any other teams who have done this?
