Omni-Directional Tank Tracks?

I’ve previously built various omnidirectional vehicles. Those included a machine I built to promote a LEGO set, which used three standard omni-directional wheels. We’ll talk more about the maths involved in calculating the wheel velocities later in this video, but using a combination of wheel velocities the machine was able to move in any direction as well as rotate. I built another similar machine, but this one used ball shaped wheels which were inspired by a project at Osaka University. Each wheel is made up of two hemispheres and each wheel has one driven axis, just like standard omni-wheels. This allowed it to move in any direction or rotate. Neither of these vehicles where particularly good at climbing over objects though. I built various other projects which were much better at climbing over obstacles. In some cases these used rubber tank tracks, or other weird wheels like the Pedrail machine which had extending feet around its wheels’ circumferences. Or just a lot of wheels like my actively flexible snake robot which could flex in two axes to get traction and also bridge gaps. But what about if we had a tracked vehicle that was also omni-directional? In this video I’m going to attempt to make tank tracks which can also slide sideways, so we can make a vehicle with three of them arranged just like omni-wheels.
