Keeping polycord on track

That's a neat idea!

But I think we're doing something wrong on ours, we only have one set of polycord belts, and two rollers, to do the whole harvest/lift/load-into-the-hopper thing.

I very seriously doubt if you're doing anything "wrong" , just make sure that multiple balls don't bind up on each other as they roll against each other.

The balls generate a lot of friction when they try to roll against each other. We've had bad experiences with single-feed systems with multiple balls binding up which led to our "dual lift" design with cords on front and back where the balls don't roll against each other.

Your system probably works better than ours if it's engineered correctly!

No, we do have the problem with multiple balls being able to easily jam in the intake. It's neat to see how you solved that problem.

The main reason we don't have much stuff on our robot, is because we're lazy....we'll spend hours figuring out how to avoid making more parts!
