Then it would be perfect in colony situations. Where you would want as many things as possible to be made from the least amount of specialized resources. Esp if the material can be recycled a large amount of times too. Meaning it's just so much simpler to replace the wheel that wears out and use the material to make more filament. Reducing the strain on the colony. It couldn't work in the modern economic model of extreme disposability with NO reusability/recyclability.

Biggest issue with using this on a rover is debris. If a rock or sand gets caught in those compliant mechanisms on earth, you can just clean it out. On mars, if turning the wheel very slowly doesn't fix it, it's there for good.

Phenomenal. What a novel concept! And so simply implemented. This is a masterpiece of design and engineering.

Not sure how practical this would be in uneven terrain, but this would be terrific for anyone in a wheelchair that had to deal with stairs.

Wow, very impressive.

I don't know why youtube recommended me this but this is really hype and creative!

Oh dang, you guys actually reinvented the wheel in a better way.

It’s a good design. The larger the wheel, the higher the obstacle it can traverse. Plus, you can increase the strength of the wheel with different materials, meaning a heavier payload. Seriously impressive!

Nice! This can easily be ‘upgraded’ to flexures from (spring) steel for much heavier vehicles. Lovely solution! Edit: just subbed to your channel… with content like this you deserve many more than 335 subs :-) Love to see where you all take this (seems to be a team effort)

Awesome actual real world usable flexure! I’m super impressed!

Fantastic design guys! Truly fantastic!

This is one of the coolest uses of compliant mechanisms I've seen yet. Great job to you and your team

Wild! I had a cheap RC car as a kid that had claw-wheel-drive on all 4 tires. If the tire slipped on the surface, animal claws (rubberized plastic, sharp-ish claws) would poke out of the tire in 3 different places around the tire, until the tire regained traction. This is a very good approximation of the idea, but with the advantages of being one single part. Would make awesome ATV wheels!

Incredible. I am absolutely flabbergasted by this simple yet eficient design.

Excellent job! Simple idea, beautiful execution.

I love finding little videos like this that show some cool idea that can change how we live, travel, etc. Very cool wheel guys. Might see this on unmanned wheeled droves from rescue operations or bomb disposal.

There was a toy kind of like this in the 80's called "The Animal". It was a motorized monster truck toy that would passively pop tiger claws out of its wheel treads to climb obstacles

Truly a engineering marvel. So simple yet so effective

I can't believe they reinvented the wheel And it's actually good

Wow, I really like this. Congratulations nice design! I am upgrading my robot vacuum cleaner with this solution, and it finally doesn't get stuck on the edges of thicker carpets.

The big flaw in my eyes is that now most of the weight needs to be held by that one hinge. Even if the leg part pushes inward against the inner sections. And it's pulling on the hinge instead of pushing. This optimizes the area of contact with whatever the robot is climbing but would limit the payload. One idea i had would be sections that either collapse inward so the weight rests on stronger parts of the normal wheel ring. Or they could potentially push these thicker sections out a little. Or I guess you could reduce the amount your hinge travels before the leg part connects to the inner section. That would reduce the strain on the hinge.
