Re: Good way to bring shooter to exact speed?

Figure out how to make a wheeled tank drive robot as reliable as possible inside of your team's resources then move on to the next design challenge.

Re: Intake RPM

Our intake had an over-geared 775 Pro as well, and we found any stall condition would pop breakers really fast (compared to older motors). We ended up running our intake under current control mode on...

Re: FMS Rankings

I personally keep track of rankings with golf scores. 4 RP = 0, 3RP = +1, etc. It makes it easier to track a few teams you care about relative to each other.
