Probably equates to best practices for all other teams since loose cables and wires may be one of a few possible causes for robots dead on the field during match play.
Andrew,

I saw a match at Dallas when 704 (Grand Prairie) came over the bump after scoring both balls in zone 2, and hit the ground hard. They hit the ground hard every time they went over*, but this caused them to shut down. I think that they eventually (60 seconds or so) started back up, but it was at least a network reset. I spoke with one of their mentors who told me that they had many problems like this on day 1, but they went away when they replaced their gaming adapter.

I'm not sure if they replaced it with the same brand or not (I think there are two that are legal this year?), but it would be worthwhile to find out, especially if you're seeing this type of symptom.

*Literally earth-shakingly hard. I could feel it in the floor 20' away.

Kris
