Hi. We are a team that wants to try a 6 motored drivetrain.
What gear ratio should we use and do you have any recommendation or experience that is helpful?
If you can send us some CAD files, it would be great!
Due to frequent questions and discussions on drive speeds, but not a lot of resources on the layouts of the possible gearings themselves, I’ve created this resource for people to see a catalogue of drive speeds that I’ve deemed as viable, and some commentary on each layout.
All drives shown here are on 6 motors, and all drives here are compatible with center traction wheel. (some drives have 8 wheels so traction will be offset from center). The layouts shown can easily be translated to 4 motor …
Xenon27 had some CADs linked here for the hole spacings.
Anything around or above 64 in/sec should be sufficient. I personally am running 450 rpm on 3.25’’ wheels, giving us 76.6 in/sec, as robots this year seems to be hanging around 64, 68, and 74 in/sec.

Shoot, you beat me to it. I forgot that he had cad files linked to that as well.
