Felix' & my Dome Drive explained

Taking apart the Dome drive.

This is a prototype of the gear-based Dome Drive Felix and I designed. It's specifically made for a bearing available here: http://www.drehteller.com/shop/produkte/cat/drehkraenze-aus-metall/pr/drehkra... , which is a pretty high-quality bearing with affordable shipping inside Europe. We designed this because we wanted a more precise dome drive than those using friction wheels, and we wanted to use that bearing. The solution we came up with is pretty tolerant to mounting position; you can be as far as 2mm off with the inner gear mount and still get a precise drive with almost no play, so no spring-loaded motor mount is needed (but can be used).

We are planning to make the final version available to the R2 builders club; it's going to consist of an aluminium outer gear, a nylon inner gear (to avoid alu-on-alu friction and alu dust in the electronics) and an aluminium hub with a 6mm bore and worm screw to fix the inner gear to a motor axle. Maybe we'll even offer the bearing as part of the package to get a cheaper price on that. Mail me or comment here if you're interested; we don't have a price quote yet but I'll update here when we do.

Very nice build. Is there anyway you can cut down the noise generated from the motor?
