But the shaft on the gearbox is not long enough to go through a hub and a clip.

We attached the wheel with a Flex Hub Flange and put a 3/8" shaft collar that we reamed out for 10mm on the other side.

Only 1 side of the wheel was supported.

There are more robust ways to achieve this set up but this is what we had available to use.

Are you sure you were using a 10mm key hub? If I recall correctly the 10 mm keyed hub from andymark is shorter than a normal hub.

Looking at the cad it fits (plus I've done it before in real life).

3rd image is the distance from the end of the shaft to the hub provided there is a 1/16th inch gap between the hub and the gearbox body.

A couple of guys on our team created paper profiles of the tote lips, long and short, then cut them and combined them into a profile that closely resembles the hook on the Ri3D 1.0 robot. The paper profile was a good test fit for our tote. We then modeled it in SolidWorks. I attached a thumbnail image, and here is a link to a DWG if interested.

This is a really impressive robot for 3 days! I love the wheel rollers to align the totes. Good job!
