The range of the radio seems adequate - we haven't done any specific range testing, but it covers our build space and the entire field FIRST had set up during the Alpha Test weekend.

The radio is a typical USB dongle. We connected it through a USB extension cord, which let us attach the dongle with velcro to the same place we had the dlink. Since it's so lightweight, even with a hard hit to the robot there's really no force on the dongle itself. I don't recommend sticking it straight into the RoboRio and having it buried inside the robot!
Thanks.
I wonder if it would be legal to have an onboard cheap ethernet switch. Next year, I want to have a node based processing system with multiple computers, running a specific portion of the code. One ethernet port will probably not be enough . I guess the dongle will be hard to hit my a gamepiece but I'm still kinda skeptical because the ASUS router sitting in front of me has quite a poor build quality and crashes every 15 mins. Is the antenna a single plane or multiple axes? A plane antenna would mean the robot would lose communications when it turns a bit.
I am also wondering about the build quality of the roborio. The GPIO seems to be build into the main package. Have you ever had any problems with debris getting in the case and making it behave very wierd? That was one thing that happened quite often with the Digital Sidecar!
I am just wondering but how accurate are the current sensors in the PDB? Do you ever use them as an effective debug strategy for eradicating nasty shorts?
Thanks.
I think I just spammed you with questions
