A faster RPM on a smaller BB wheel or a slower RPM on a larger BB wheel would likely have similar results (not accounting for rotating mass and wear effects).

So if a given team is running their intake rollers at X RPM, I think noting the type of wheel and diameter would be pertinent.
We prototyped intake wheels and came to the conclusion that the max linear speed we'd need to pull in the tote (assuming no slip) was around 5 ft/s. To achieve this we had selected 2-7/8" banebots wheels paired to VersaPlanetary geared to 30:1 and powered by a bag motor. We would then be able to slow down the intake from there if needed. I want to note that currently our bot doesn't make use of intake wheels so this is where our data ends.
