Happy New Year!

Here's the first video of the year, early for Patrons. This one goes out publicly on Jan 9th. Finally an actual use for the Mobius strip tank!

Mobius Track V2 - PREVIEW VERSION

A mobius strip or loop is a one-sided object, and we can easily demonstrate the principle by getting a strip of paper, putting one twist in it, and joining the ends together. The original tank I built has tracks like this, because it was suggested in the comments of another video, but it was hard to think of good reasons why it needs to exist. After I’d built this I realised that where the track twists, there’s a section in the middle where the track is vertical, and this would allow it to bend the other way at this position.

Excellent proof of concept. You will definitely want to compensate for tread sag in the middle section. I'm curious how performance will be affected if you eliminate the vertical rollers on the top. One one hand, those rollers are extra friction/wear points that cause excess tension in one turn direction (let's just say turn configuration A). On the other, I suspect that they are important for maintaining a good track path for turn configuration B. (Of course, A and B are defined with respect to the counter- or clockwise orientation of the twist, such that reversing the twist switches the location of A/B in the global reference frame).

Those rollers need to be there so keep track tension when it bends, otherwise the distance between the ends gets shorter and the track will just sag in the middle.
