I am sure that there will be good use of this concept in the future. I have often thought about designing a car that could change its body shape just a tad according to its speed to reduce air resistance.

Another great solution in desperate need for a problem it could solve?

This product will go NOWHERE in the passenger vehicle market. It's fine for robots, but that ride is WAY too bumpy for human beings.

I love it! Imagine the ratio difference in torque and speed, and obstacle clearance. Think variable ratio transmission. Great!

I'm no mathstrologist. I'll just keep wondering if wide tires cancel out ground-hugging aerodynamitry.

Looks like it would be useful as a 'folding' wheel.

Probably it is made to replace the gearbox similiar to a CVT.

Mud boggers are gonna love these. When the mud pit gets rutted with tall, narrow tracks, just widen the tires and straddle the ruts.

It's funny that it took researchers and scientists to come up with this idea that is just like a toy I had called the flex from the 1980s did the same thing thank you scientists

The weak point is the 'hinge' and that is in exactly the position that will receive the most wear and tear in off road use. When the hinges start to break....!
I've a mini-digger, that has rubber tracks, and the failure point of those, is the steel cross pins that the drive wheel engages, which get ripped out of the rubber. So the weak point is the bonding into the rubber. These wheels will probably have similar fail problems.
If I can see these problems, then potential buyers will also, and will want some very convincing answers.
