pic: Anyone doing this?

Again this isn't a design we're using.

The rubber that we used last year on our bot's rollers was actually the lining of a rubber innertube. We had just enough at a mentor's house to use and it worked perfectly.

Our team is using a variant of this, which allows for using less rollers to ascend to the top, and also allows the roller system to double as ball storage (without any "hopper", we can hold around 20-25 orbit balls). In fact, we've managed to get the rollers to do everything manipulative on the bot, without any major modifications to the roller system at any point (that is, it's almost symmetrical over a horizontal line through the middle).

We'll post some pictures once we have a 'bot up and running, which hopefully won't be too much longer.
