I'm not sure about the raspberry pi specifically as far as "better". The setup is legal, so long as the board is supplied with power from a legal source. I'll also note here that if the vision system has a tendency to dump packets and cause high latencies on the field, then the FTA will come talk to you about why there's so much network traffic (not in the rules directly -- it's more a GP thing, which IS in the rules). So at least be aware of your network impact.

We're trying an offboard processor following the whitepaper 987 put out at the end of last year so we can offload Kinect processing from the cRIO. We also have some kids dedicated to the interfacing of the 3 systems (cRIO, pandaboard, & custom dashboard). This vision system will (at a high level) not receive communications from the cRIO, but rather be a standalone processor that spits out information which will override certain logic blocks of our autonomous code. That way, [when] the vision system crashes, the autonomous code still has a default set of logic to perform (probably dead reckoning).
