The RC I tested on the bench is not the one that was in our bot when it reset, so I have bench tested one, and 'field tested' another.
I dont know why there would be a large electrolytic cap in the robot controller - Its powered by a battery, which would have very little ripple - but I will open our spare one up again and look for large caps.
The RC takes quite a bit of power - it powers the radio modem, any sensors you have on the same breaker, any servos connected to the PWM outputs - so some robot configurations might drop out faster than others.
But even still, caps are intended to smooth out noise and ripple on the power supply, not to hold it up during power interuption.
If anyone has the ability, please verify my results in your lab. I believe this is potentially a serious problem for all teams - having your auton mode restart, or loosing the link for several seconds during a match can result in your bot being damaged in a collision, or loosing the match in the last few seconds.
