The radio is far from the VRM and as far away from any motors as we can get them. The closest one is a drive CIM and that is something like 12 inches away.
After we swapped out the barrel connector we had no issues the rest of Thursday and Friday all the way to the last seeding match on Saturday.
then 3 times in like 8 matches.
Had all the orange and yellow hats looking. Nobody could find an issue.
One thought I had was this. We are using these wide polyurethane beach tires.
We notices when we were on the practice field we sold get a strong static electricity shock when we touched to bot after driving a while and we could also hear a discharge when going over the defenses. Never seen this before with a robot.
We always lost comms not after a violent move but rather when beginning to cross a defense.
Now I am wondering if we have two problems. Radio power, fixed by POE and the new barrel connector and a static discharge causing another failure mode?
