Re: [FTC]: Tri-Wheel design

Instead we settled for a four pair dual overlapping "cam-wheels" design pictured below. It performs as well at climbing as any of the ~40 bots we have seen here in Illinois so far at league and qualifier competitions. We will be scoring all 160 mountain points most of the time in a couple more weeks, and we may be hitting the 2nd mountain zone in autonomous by then too. Our goal is for our bot alone to contribute 200 points to our aliance effort once we tune our autonomous efforts.

Yeah, I've seen your split wheel design, looks impressive. However, I did see that your wheels stick on upper-mid bars. Did you sort out that problem?

We are rookie team and don't have much to start with. Definitely no CNC for us . It does look like even veteran teams are struggling with this season game.
