We considered doing it, but in the end we were dubious as to whether we could handle the precision and time needed for CADing and machining the the 3-lobed plates to match needed locations & size acccuraies for axle bearings and planetary gear shafts etc well enough for decent function and durability.
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.
