Re: The 8.2 (or 8.3) Battery Voltage Bug
Yes, as Chris31 said above, this bug cost us two whole matches today at VCU.
We were quite frustrated in that we could not isolate the problem.

What the "bug" does is it returns a constant 8.2 volts on the OI, YET, the Low main bettery light does NOT cut on. In addition, the 8.2 volts does not change when you do manage to get systems running (It should drop with current draw).

We had interesting behaviour when our RC was running this bug. First off, our autonomous mode did not run. Second, pwm03 worked properly, but 04, 05, 13, and 15 stopped. Our relay based loader continued to function.

The thing about the bug is that it was very sparotic. It would randomly cut in or out, when you started up the bot, yet I don't think it ever changed while the bot was in operation.

-Sigh-
This bug cost us two whole matches when we finally had our robot and autonomous very functional.

Just to teams about to compete out there, keep your eyes on this one, it will kill matches....
