Animation and animatronics are kinda Disney's thing. Imagine what could be done if all this time, money, and talent were being used on something other than a tourist trap.

Five nights at disneys?

Don't kid yourself, "they" also don't come up with this stuff. Researchers at universities do, and companies buy the project and continue to hone it for their sole purposes.

Chebyshev was the first to develop such systems in the early 19th century!!!

Great math

Legendary comment 😂😂

Imagine having a jaw. This reply was made by the mollusc gang.

Yes.

But,counterintuitively,compliant mechanism have been shown to be more durable than their contemporary counterparts. Besides, any decreased performance is made up in the time and cost of device construction

"It's incredibly difficult to not doubt the durability claims." Their technique specifically optimises to minimise the torque. It obviously cannot remove durability concerns, but it specifically optimises the design to reduce the damage, to increase durability. Not to mention compliance almost completely eliminates backlash that exist in "traditional" mechanisms.

They surely both have their pros and cons, but keep in mind it's also possible to build flexure mechanisms with off-the-shelf and replaceable parts like sprint sheets and wires, although with that method complex shapes as in the video are harder to build.

@@jonasdaverio9369 this is exactly not what a compliant mechanism is

Very true indeed, youforgot to mention the major aplications in STDS!!

yes, you can find it if you search google scholar for the title of the video. if i post a link, youtube will probably delete this comment

Check out Theo Jansen on YT. He's an artist/engineer. That first leg design is straight up one of his. He said it himself "The lines inbetween art and engineering exist only in our minds", or something like that lol.

@@lvbboi9 They call it the Jansen leg in the video. I'm sure they wouldn't present it as their own invention.

Same.

Likely following a script

Better than things with say minges that slide over pins or bushings. The sliding parts wear against each other and the shape changes slightly with use.

Only if they reach plastic deformation, if they're properly designed they won't break down.

With this technology, you save in materials. By saving materials it becomes lighter, and also cheaper.

Same lol

I feel like they put a lot of empty-speak in there, complicated sentences + too many fancy words, when in actuality what is being said is quite simple. I may be wrong, but here's my try at an example translation: Original: _"Our method takes as input a conventional mechanism and replaces rigidly articulated joints with flexures. Thin blades of elastic material whose shapes are automatically computed in order to optimize the performance of the compliant mechanism, there are several design objectives that need to be taken into account."_ My version: _We turn a conventional mechanism and replace rigid joints with flexible ones. These joints are made of thin, elastic blades, and the shapes are created by a computer. Several aspects need to be taken into account._ Original: _"Furthermore, when using 3d printing, residual support material increases friction in the joints. As shown in this example, these drawbacks can amplify in unfortunate ways leading to unforeseen deformations in the structure and even failure. We show the ability of our method to scale to miniature designs found for example in small-scale animatronics. By explicitly modeling compliance we can predict and leverage the deformation of the structure and maintain proper functioning with good precision."_ My version: _When 3d printing, ressidual filament can make the joints harder to move. As you can see here, this can lead to unpredictable deformations and even failure. This design can also be used in a very small scale, for example in animatronics. Our compliant design is very precise and predictable._

@@slaveNo-4028 it was really nice of you to write this

This is very useful for precise positioning. It avoids almost any kind of backlash and convert motion in a huge ratio

Oh no, how awful Disney funds research into compliant designs which could be used in the design of safe animatronics, how evil of them ( ~ ._.)~

@@Soken50 once you're shackled to the mouse you're in for life.

@@Fry09294 it's just research, even if they patent it anyone can use it in 20 years, relax bud.

@@Soken50 I am relaxed.

Compliant mechanisms is a very recent advancement in the mechanical industry. They've been around for a few years now. Nobody has a patent on them because it's a method, not an invention.

I was thinking the same thing.

ain't no way Disney is going to open source this! They might publish a research paper showing the results, but they are more likely to patent it than to release it. They are in the business of making animatronics for all of their theme parks after all!

@@TomSepe wrong. kzfaq.info/get/bejne/f7uVZtB40NTLo2g.html

Open sourced Disney, I can hear Walt laughing from his grave.

This has the potential to change so many industries, from medical to even aeronautics. It'll be real selfish of Disney not to share this software. At the very least offer a payed version

I don't think there is a single linear spurving bearing on the market that can handle those stresses yet. Let alone one with underlayed wafer vertices to increase lifespan.

Won't someone think of the panametric fan! The modial interactions can't be understated here

@@DOCTOROCTAGONAPUSS Love your username.

@@AndrewDasilvaPLT Lol thanks.

They gotta start taking over the world sometime

yeah, they're quite big into robotics. With stuntrobots etc.

Yeah they’re a multibillion dollar robotics and entertainment company, could also be a drug company jk

Like their breath weapon, dragon flight is magic based.

Probably someone just connected motors the other way to the power supply

This was said b4 i think in the past. Someone wanted to commit suicide decide to harass area of interest(robots) maybe. Since the move is silent, maybe if 1 is wheel to move forward fast then maybe need to be slower to crawl like that.

Dunno the name (ACM?), or if the software is available anywhere, but here's a page with the research paper about it. la.disneyresearch.com/publication/a-computational-design-tool-for-compliant-mechanisms/

"Proprietary Disney Software Now Sign This NDA"

down to micrometers.

It's probably a good bet that some chemist is working on a molecular gimbal right now.

If you find let me know!!

Dunno the name (ACM?), or if the software is available anywhere, but here's a page with the research paper about it. la.disneyresearch.com/publication/a-computational-design-tool-for-compliant-mechanisms/ I really want it too, hopefully it will be available online.

You won't find it. Its Disney, after all. It'll be proprietary. sorry :(

@@TomSepe wrong. kzfaq.info/get/bejne/f7uVZtB40NTLo2g.html you can't download it though, but you can use it

In general the idea is that these mechanisms are actually more robust as the movement of any given point is far less than a typical mechanism and instead it spreads out the movement by flexing over the greater length. but I agree that in these examples, a lot of sections seem to be flexing too much, to the point where it looks like it would fail easily, also there is the added downside that it cannot be repaired, only replaced, which is fine for something like a space object or a industrial application where replacement would be done anyway so the added time between that is preferable. in the case of something like a car I'd rather replace a small part frequently than need to completely replace the entire steering mechanism when it catastrophically fails at some point haha

@@audi4444player well said. design for small max stresses in the deflecting members so you remain under the fatigue life of the material.

Well as long as the stress in the material maintains to be in the elastic region.

Its the reason why this will never be largely used.
