Ratio is not fully optimized imho, but this is what we have now on each wheel:
CIM + Mini-CIM
CIMpleBox: 12:56
#35 Chain: 12:24
6" Vexpro Mecanum
Some notes:
The JVN spreadsheet (Very useful) puts the top at 12 to 15 ft per second (going forward, not crabbing).
In practice, I think we are a bit slower than I'd like to be if we are going to be a fast nimble robot rather than a pushing robot. So, I would am probably going to push for a lower ratio (more speed) by going to a 16T sprocket rather than the 12T.
Also, the mecanum wheels were not my favorite choice. And I think I was right. They are scaring me. A number of the small wheels on the 6" mecanum wheels are pretty wobbly already and they don't seem to roll well. Have others had issues with the Vexpro mecanums? do tell...
