"I did see a little mean robot 'Cerebral' or something like that take the center goal and team 60 and place them back against the operator station then the battery connection or breaker went. For those first few seconds the 'Cerebral' bot showed they had what it takes for speed and power."

Apparently they DIDN'T have what it takes for speed and power if they blew their breaker during this maneuver. Our robot could apply 3900 pounds of force with stalled motors, but we'd be drawing 110 amps! It doesn't do any good to have lots of power if you haven't tuned the gearbox and drive train to operate without blowing breakers during the match to take advantage of it.

Y'all should also be aware that the SquareD breakers have had some problems and sometimes blow prematurely - need to consider this in the power management as well.

FYI, we (SPAM, team 180) have 12 fps speed in high gear at 8 amps per motor, and produce 770 pounds of force (limited by belt traction - we don't ever get there) in low gear at 30 amps per motor. Check out KSC videos - match 63 (which we won the outstanding play award for) and final match 2 in particular - to see us in action. We pretty much could beat anyone to the goal and push anyone and anything, although noone had file cards for traction like Beatty. Heat Wave - are you going to put that stuff on your brake for nationals? I don't know that we could break it loose, although we might bend the PVC trying.
