Thank you all again so much for your advice. We've decided to go with the CIM motors (full size) and VersaPlanetary gearboxes.

With a 5:1 gearbox and 6" wheels, that gives us 1717 oz-in (107.3125 in-lbs) of torque with a speed of 6MPH.

Do you think that's enough torque to move a ~60lb robot?

I attached a spreadsheet with our list of parts and speed/torque calculations. Any final advice you could give us would be great!

Thanks!
