Re: pic: Concept Octocanem Drive

My first impression is that there may not be enough stiffness to the module bending/twisting... Is that .25" thick plate with .25" wide 'struts'? It's good to see all the standoffs, but I'm concerned they're also too thin and that the plates won't have enough stiffness to avoid bending between/around the standoffs anyway. Perhaps go up a little wider on the struts? A gearbox might be fine like that, but in a spur gearbox there are essentially no loads trying to bend the plates of the gearbox... this is not the same loading case.

Which wheel is the pivot? How are you going to drive the first wheel? How are you going to drive the second wheel from the first (looks like there may not be a clear path for a chain/belt currently)?

It looks like those are 6" wheels... are you sure you don't want to use 4" and smaller wheels? It'll make your module way smaller, lighter, shorter (less of a moment arm for the side-loads of the articulating wheel), and means you need less of a gear reduction before the module to get a given speed.
