Re: Intake RPM
We used upper and lower Bag Motors on a 10:1 VP with a 1:1 9mm belt from gearbox to 2.375" Banebot wheels. Theoretical RPM on those wheels is about 1300rpm. Robot ground speed was max 15fps (though I don't think we were ever near full speed when intaking). The belts were fit slightly loosely on 3D printed pulleys to create a "slip-clutch" to prevent motor stalling. The plastic pulleys held up just fine all year, no broken teeth, and even took quite the beating from impacts of robots and walls. Never had a single issue with belts from ratcheting over the pulley teeth either. We've done this a few times for these very low load type of applications - I would NEVER do this setup on our drive (though I know as our wheel axles got bent over the course of the year, we did quite a bit of ratcheting on those belts...but again, no issues).
