What is the tube made of? We have been searching and testing different materials for ball bins on our robot.

Nice and clean design, just a few issues

How did you over come the balls sliding out the bottom, and how do you get balls to go inside of it, if my understanding is correct wouldn't the central spiral need to spin fast enough to hold the balls in, and any faster wouldn't it push them out the top, just wondering.

1/16" plexi. As for the issue of keeping the balls in, that will require some testing but our roller/drive is made with "universal" holes so we can slide it forward and backward in 3/8 " increments so if the balls have problems staying in we can just slide the roller back to keep the balls in. :D

That is very cool. I like the clear appeal on the robot. So just a quick question on the blue roller in the front...what kind of material is that made out of and that is the way you are getting the orbit balls into your spiral correct?
Best of luck in your competitions!
