Guys,
After designing and fabbing these wheels last year we hit a problem that I would like to let you know before its to late. The yokes or brackets that hold the ends of the roller take a lot and i mean a lot of loading when making lateral movements, and or contacting any other robots/ramps. I made ours out of 1/8 6061-t6 with a small bend radius. Upon a few minutes of test driving we had a lot of bent yokes which lead to rollers hitting each other and the hub. We ended up with 11 gauge, (~.110) steel which worked like a charm, we also put a huge radius in the corners.
Hope it help.
