No currently made capacitor is at all near large enough (in terms of energy storage) to do this.

Re: Did I read <R32> Correctly? Six CIMs?

Aldaeron,
It is unlikely that two batteries will be allowed. Batteries are not happy when connected in parallel when they don't match in characteristics. The manufacturers frown on this practice unless the batteries have been installed together and charged together from the beginning. Systems that use batteries in parallel often use Schottky diodes to isolate the batteries. However, we would need two 600 amp diodes at $100 each. The diodes would drop about 1 volt. Let us not forget that adding an additional 12 pounds is significant in our competition as well. Teams are already struggling with the 150 pounds most robots achieve. I fear we are stressing our participants with lifting these weights throughout the season.

Last year, I said "22 motors? Challenge Accepted."

30 motors? Not even going to try.

They exist, but would be prohibitively expensive.

Carbon aerogel super/ultracapacitors.

Also, these things are dangerous.

Re: Did I read <R32> Correctly? Six CIMs?

I was not thinking of a six motor drivetrain, but a four motor drivetrain and a CIM for the disk launcher.

The sixth CIM? I dunno, maybe a big defense fan?

Save a few CIMS for climbing the tower?

Re: Did I read <R32> Correctly? Six CIMs?

I didnt read most of the posts but is there a limit of how many motors or motor controllers a bot can have this year.

Thanks team 3633

Goodness, YES. Please get a copy of the rules. It explains a lot, and if your robot does NOT follow the rules, you will not be allowed to compete. Really, it is very important.
