This is a great discussion on static electricity. Supposedly the robot frame is isolated from the electronics, but that doesn't mean it can't cause problems.

I only saw a small mention of VRM wiring, but suspect some teams may be hurting themselves by pairing up the radio and LEDs/lights on the 12v/2a bus of the VRM. There is a rule and checkbox on the inspection form to prevent this, but I'm not sure it was consistently applied across districts and regionals. We're all volunteers, after all.

From non-FIRST experience I would hot glue or permanently fix in anything with a barrel connector. They like to work their way out with vibration. We've seen this a lot with CMU's RoboBuggy.
