There is nothing wrong with using the CIMple boxes to save a few bucks. The kit sprocket reduction (26:12) plus the CIMple box gives about a 10:1 gear ratio, which is a nice ratio for 6" mecanum wheels. If we're starting from a 2012 kit of parts, that move saves about $180 as compared to using Toughbox Nano and AndyMark hubs to direct drive. If you want to use the same equipment on a competition robot next year, though, I think the extra $180 is a good move. The Nano boxes have the following advantages over CIMple boxes: takes up less space, no chains to mess with (easier to build + more reliable), Nano is a
nice box that runs really smoothly and is probably more efficient than CIMple + chain.
Having said all of this, and everything in my previous post... honestly, I agree with the people who suggest doing a kitbot on steroids (a nice 6WD robot) instead. It sucks when you can't climb an incline very well and other robots can shove you around at will.
