Re: Polycord on tote intake: recipe for disaster?

In 2012 we used polycord to move the basketballs through our robot, and we made our rollers out or 2" (IIRC) PVC pipe that we bolted to the driven shaft, using PVC endcaps drilled out in the center to keep the rollers concentric with the shafts. Then we cut small rings out of the endcaps and slid those to where we wanted the belts on our pulleys, to create guides on the rollers. You might have decent luck using some sort of similar system, perhaps also putting tread on the PVC to grip the totes better at the front and then use gaps in the tread to align the polycord.

I can't comment on how well the polycord grips the totes, but it had a decent grip on the rollers when properly tensioned. Hope this helps, good luck!
