Omni wheels?

[Mentor08]

The opposite corners...hadn't thought of that. I don't think that they are the same diameter.

We used casters on the front last year. Big mistake, no control. My thinking is that omni's on the front might end up being the same with a little more control. Hopefully putting them on the rear will give more control.

Omnis on the front will give you only marginally more control than casters--rear is the way to go.

If you wanted to be in the true engineering spirit then you could build your chassis such that the wheels are interchangeable and then try both varieties.

Good idea on trying it both ways.

Is it better to use 1 chain per side or 2 chains per side?

You want to maximize the amount of wrap of the chain around the sprockets to prevent the chains from slipping off. I recommend two chains, one going to the front wheel and one to the back. Make sure that your sprockets are aligned with each other.

Thanks!
