I briefly tried deploying it to the roborio but is crashed a few minutes after launching. I have not dug into why yet. It was finding the target and posting data to the Network Tables.

If you have the funds available, you cant get a Kangaroo PC for $100 https://www.microsoftstore.com/store...ctID.328073600.

We had a USB lifecam connected to a kangaroo running grip connected to the rio via a USB to ethernet dongle to the radio. We had our green LED ring connected to the PCM so that we could turn it on and off. One of our students designed a 3d Printed mount for the life cam and LED ring as well: https://twitter.com/therealsimslug/s...84190541889536

We had issues with the ethernet connection to the rio with the new radio. We were able to run off of the old dlinks just fine. Never quite sorted it out, and never got good enough at shooting high goals to really use our vision code. But GRIP was very easy to set up. Running it on the kangaroo and using the network tables allowed a small enough lag for us to center on the goal OK. I think if we were to continue to pursue vision, I would come back to this set up.
