Agility, and profile mostly. Notice how the footprint of the drive components is very small and delegated into the corners. leaves almost all of the footprint profile available for anything else. But the main factor is agility. With this design, we can go in any direction, at any time, in any orientation, while spinning. Also instantaneously change both heading and orientation at any time in any other direction/orientation. For example heres a video demonstrating these advantages: https://www.youtube.com/watch?v=irf7pGiCru8 This years system should be an order of magnitude better than what you see in that video.
