We began the season with GRIP running on the roboRIO for an IP camera. For some reason, it would never work on the official field FMSes (it worked fine in our shop and on the practice fields).

We decided to throw all of that out the window and we eventually rolled a Python script utilizing OpenCV on a Raspberry Pi 3 with an accompanying camera module. The Pi communicated with the roboRIO through a USB to Ethernet cable (Ethernet went into the Pi, USB went into the roboRIO's USB Host port), thus creating a separate network between the RIO and the Pi. Finally, we used NetworkTables to actually transport data on the connection. We hoped to avoid any sort of meddling that the FMS might cause by creating our own direct connection between the RIO and Pi (bypassing the radio altogether), and this seemed to do the trick for us.
