I just reread the post also. His comment about a 'field' battery has to be in reference to team 34 and if I were a good lawyer I'd classify it as hearsay. I'd prefer to defer to Ed Sparks et. al on their battery supply.
Regarding the ref statement about 12 volts - I'm with you there. I don't know how you get a good telemetry stream stating you have 12 volts and then can state there is no power to the robot. I'm NOT throwing the volunteers under the bus. They made their call and I'm good with that. But it don't make sense.
We can't do our assessment until April 1st in Raleigh. I'll quarantine the part and meet you in Atlanta. I don't want to open it until you have had a chance to see the part.
I absolutely don't believe we had a battery problem. We spent a fortune on a new 10 bay Deltran charger and had a total of 6 brand new batteries in our fleet plus 4 from last year. And a couple of students working on power management. We played ONE match per battery the entire weekend. The battery would come out and straight back to the charger. I know it isn't optimal for the battery but we can deep cycle them after the event. Even with all that effort we don't have the S/N on the battery for the failed match. We need to improve that.
One issue we need to inspect is a loose connector to the PD or power switch. That is an open question in addition to the potential defect on the switch.
Don't you love it - great great training ground for the students !!

Al, BTW - I got drafted as a rookie barely useful robot inspector under the fine tutelage of Ed Sparks. I didn't get to put as much into it as I would have liked but hopefully it helped out. I think I'd like to volunteer to help out in Raleigh. Who do I talk to?
