This photo reveals a bit more about the inner workings of the compound unequal length articulation that is not visible from the top views. The two articulated sections are unequal length so that the wheels do not touch when articulated 90 degrees. I tried numerous configurations before settling on this geometry. Other configurations that I explored either allow more mass outboard or do not provide 90 degrees of stable articulation. I am unaware of any other articulated vehicle with this geometry.
