With a bit of trigonometry and some observation we can estimate a theoretical limit to the maximum length. I assume you are looking for the maximum length that would run on the sharpest possible curve, which appears to be one made with flexible track. By observing this photo of 52 flex track pieces arranged in a circle, we can estimate that each piece can ...

I was able to find a few elements that are able to make this connection possible. I'm guessing the designer used some type of bar-sized element which is made from a different material that is able to compress slightly more than regular ABS. For example, the softer plastic used on some minifig weapons seems to work nicely: Another option could be flexible ...

The math you're suggesting may work for going straight forward or backward where slipping is limited. For a turn, it will not come close. Even getting the center of rotation of the turning robot will be difficult. The tracks will have to slip. A tracked robot can not turn without those tracks slipping. Differences in friction will alter the turn. More ...

A 360 degree turn takes: (width of robot/circumference of wheel) turns, neglecting track thickness, assuming the tracks are at sides if the robot. The length of track doesn't matter. Your robots non-slipping part of the track is traversing a circle of diameter=width of robot. The other parts of the track are sliding across the surface. A longer robot / ...
