Hello all,

I had a question about some ball lift systems. Currently, my team seems to be looking at a system of rollers one one side of the ball, with a wall on the other. From what i've seen, this will cause jams and make the ball lose momentum due to the friction, unless we use Teflon. I'm thinking of a guardrail system with a belt (there was a video of a similar idea here) or 2 systems of rollers and polycord on the top and bottom of the ball. What does Chief Delphi think?
