pic: Another concept study

[Nemo]

I've been studying the details of this render in several sittings, and I'm still in the process of absorbing some of them. This is really neat stuff. Thanks for posting!

It looks to me like the speed on the traction wheels would be something like 3.5 times slower than the mecanums, based on wheel size difference and a guess that the traction wheel's gearing is about 2:1.

The speed difference is mostly due to the size difference of the wheels. The CIM drives the center gear. The Mecanum wheel is driven off a second reduction going one way and the traction wheel is driven off the #25 chain and a second reduction going the other way. (I don't have the exact gear ratios handy - must have overwritten the spreadsheet.)

Ah, yes. I missed the fact that the traction wheel doesn't get the second stage reduction that the mecanum wheel gets.
