Thats my understanding of it anyways. Please do correct me if I'm wrong.

Seems unlikely, since the chain runs between two wheels, neither of which is on the module pivot. I'm guessing the arc that the omni follows closely approximates a circular arc that maintains chain length. Since the omni doesn't have to move very far, I'm thinking this can be close enough (though I haven't run any numbers).

I believe they are these.
