Looks nice!

Last year we tried a very long (30 ish inches C-C) 9 mm drive belt and direct driven rear 6" HiGrip wheels supported by plastic bearing blocks. The front omni wheel was mounted in VersaBlocks with a WCP cam for tightening. Not sure if it was the length of the belt or that it was only 9mm wide, but the belt skipped a lot and make some awful noises, even with a lot of tension. Shorter belts may work better, but you way want to use 15mm belts. We ditched drivetrain belts for a while.

Our plastic bearing blocks cracked a lot with a full weight robot and minimally cantilevered wheels (wheel right at edge of bearing block with 1/16 acetal spacer). And this was a year without contact. I would test the plastic bearing blocks with weight on them. Maybe we were unlucky.

Other than the slapping of the chain, how was chain in a tube? What sprockets did you use? 18T? 16T?
