This is an Anti Oloid

Looking awesome with no practical application is my specialty.

I can imagine a cockpit in the center of the mass.
It'd make a cool star wars vehicle.

[Delicate_Disaster]

Imagine trying to put it away drunk but it just keeps crawling away 😂

[lillyrith]

I love how it “walks” instead of rolling. Little guy. ::)

[krystal_vector]

That’s the shape they put on the cover of all college calculus textbooks 😂

The anti-oloid itself may not have an application, but a mechanism based on its geometry actually makes a terrific vat mixer. Two crank arms offset by 90°, a way to fix a barrel between them. Put the components to be mixed (usually dry ones) in the barrel, fix it in the mechanism, and away it goes with a tumbling motion.

"Aren't you a little old to be fascinated by a wonky, rolling physics toy?"
"No, no I'm not."

[TwixiMixiPixi]

I would say that looking awesome is a practical application.

Add a shaft... that Could be a flow through impeller...

[SunburntHands]

Just loft the two surfaces. Just loft 'em. So simple. Just loft those bad boys. What?

[Confetti_Spaghetti]

Thats a cool shape, thanks pim from smiling friends

[Zeero]

If you use these as bearings between plates, you can introduce fluid flow directly at the bearings, and it will rotate the bearings, thus smoothly translating the two plates in anti-parallel fashion. You can do this with a normal screw, though.

If this is an anti-oloid, what's an oloid?

[moewoi]

I'm sure someone will make a viral drone propeller out of these

[nellepolansky]

That shape would make fantastic earrings.

A practical application could be a rolling mechanism in robotics. Incorporate the anti-oloid into a robotic rolling mechanism. Its unique rolling behavior could be utilized in environments where non-linear motion is advantageous, such as navigating complex terrains or precise movement within confined spaces.

There is also a version that isn't a ring, "filled in" so it always has a line of contact with a flat surface, much easier to see how it rolls on that one. Yes I do have both in the room with me.

The way this scratches at my adhd so perfectly- oh my gosh. I NEED this!!

"Does it have a practical application? No, no it doesn't."

My brain: BUT IT'S SO FREAKING COOL!!
