 By the way, a piece of advice to all those who haven't gone to Manchester for Kickoff before: Go. It's something you have to do at least once in your time in FIRST. - Billfred [more] |

I Agree as Always
Al (and others reading this),
I agree with you 100% with regards to the starting current instantaneously going up to over 100 amps on many motors (FP and Drill included). The point I am trying to make here is to NOT DESIGN your robots pushing torque at a current draw over 30 amps per motor. If you do, and you get in a pushing match, chances are you will trip those annoying little resettable breakers. I have seen over the years (and I'm sure you have too), many teams pick a design torque at max power which is usually at 50 - 60 amps or higher (for FP, drill, and Chiphua) only to see their breakers keep tripping during long pushing matches. I am trying to save some rookies the agony of a trippy robot drive system. -Paul |
