Re: Robots not under driver control- does it happen- do you determine why?

Or an intermittent blink? Solid yellow (or Red/Green) - off - working again?

399 had the second during build. It manifested itself as a lag, especially when driving backwards.
We were able to narrow the cause to a single Jag [the one that intermittently would flash], and by removing it solved the unresponsiveness and all of our CAN issues.

Under BDC-COMM, that Black Jaguar would remove itself from the CAN bus and not respond until it was re-enumerated, when it was commanded to go a certain direction [Backwards].
