- Rube Goldberg Ep. 4: The Chebyshev Side Quest
•••
This was a side quest because I accidentally spent 2 full days turning this into a standalone kinetic sculpture. I may not even used this in the final sculpture, but once I saw the animation of the linkage, I decided that I had to bring it into the real world. Trying to get all the linkages to move together without interference turned out to be a huge challenge, not to mention connecting a motor to the thing in an aesthetic way. After trying a variety of different gear ratios which didn’t fit that well, I decided to bust out the chain and sprockets from my animated gif project. Love the way it turned out!

Hofstadter's Law: It always takes longer than you expect, even when you take into account Hofstadter's Law.
Hofstadters law is strong in my shop
that’s hilarious 😂
sounds like: T=H^2
Thank you for my new excuse when cooking dinner
@@GLDn1No, because when you take into account H^2, it still takes longer, so you realize, it was H^3. And so on.
bro just designed a new sex toy and didn't even know it 😂😂😂😂
Yup
Looks like it, but somethings telling me it won't survive the workload.
Have you any idea how many Newtons it takes to penetrate clamping and shaking body?
Because there are people who have taken some measurements. Not me but I'm on the same kink discord. It takes some oomf. We managed to get decent feeds and speeds with 100w servomotor. Works for compact build. For bigger toys and alternative "routes" 180w servo seems to be the sweet spot. Has oomph on the lower speeds and has the speed when it's needed.
what are you??
@@Kregorius
People in 1980: Man, with this new servo technology we can automate machinetools and increase productivity.
People in 2023: Plastic dick go brrrr
@@ThibJoker this is so messed up bro..
i can feel my head shaking while looking at this
?
@@eksboks148 another comment could be "But why?"
I know what ur thinking... lol
An egg beater for the space station?
i can smell my head shaking while hearing at this
I can already see it's application in bettering human lives
Is this a joke?
@@Vfulncchlit can be used as a 👉👌 toy
@@Vfulncchl i doubt it. The top comment is about sex toys so why would this be a joke
@@Vfulncchl Could you seriously imagine this changing the life of anybody ? I'm not saying it won't be the case in the future but for now that's uselss
@@TehAzaack No exactly, I couldn't see the applications, but maybe there are some out there. But probably the mechanism has been known for a hundred years already
You've invented the "stroker 3000" nice work now put an attachment to it, and put it in the very back of a magazine 😂😂😂
Sick chain and sprocket print!
Always comes in handy!
@@Engineezy Can you make Minecraft Piston IRL with Gears? Please. 🙏
@@davidarvingumazon5024This is the coolest idea! I always wanted to see if redstone mechanics could work in real life
This reminds me of old printing presses with a flywheel. The flywheel is constant, but the motion of the actual print/type was like this so it would imprint and release fast, but move slowly through part of the cycle.
I used to have a fairly old book with hundreds of mechanical motion linkages described and illustrated.
Awesome! A lot of really cool things can be achieve with mechanisms eh!
Awesome! Could you remember the name of the book? Thanks for the info 😁🙏
@@RobQuinneyFive Hundred and Seven Mechanical Movements
@@PeriapsisStudios2000thank you for responding!
@@PeriapsisStudios2000They could've stopped at five-hundred, but I appreciate that they went the extra mile adding the last seven.
It pulls out really fast!
Wdym "Out"???
watching it at top speed reminds me of the Pixar Lamp
😂😂
looks like that thing could crack a whip!
That motion looks beautiful :)
I'm curious where your going to use it
I have an idea!
@@Engineezy Can't wait to see it :)
Am I thinking what you are thinking? 🌚
@@ayushdesai5612Yes 🚬🗿
@@ayushdesai5612Absolutely
My first thought was "wait, that's more than 4 bars," and looking at it on the Wikipedia Chebyshev Linkage page, it is two Chebyshev Lambda Mechanisms (illustrating symmetry), and therefore I believe it is over-constrained. A little surprised he didn't mention that.
This is genuinely the smoothest moving 3d printed mechanical linkage I've ever seen.
How much post-print work do you do on these parts?!
Its the bearings, they make all the difference
@@Engineezy ahh that makes sense!
Awesome work though man, binged most of your content lmao
@@Engineezy I wouldn't mind a shortlist of hardware- I just got into 3D printing a week ago and quickly found myself needing bearings. I am using 6003 2RS but looking for smaller ones like these.
What printer and filament do you use? @JBCCreative
I can think of a pretty useful application for this mechanism. Just needs a small... or large, if that's what you're into... attachment
I had a meccano set when I was a child but I was so lucky because my mom got me the premium one which even came with a little electric motor and we had a lot of fun with that building all sorts of nifty things like that not quite as sophisticated as what you have available but great for a little 10 and 12 year-old minds...
If anyone reads this has any kids I highly recommend buying them one of those MECHANO sets!
A Rube Goldberg machine is essentially a device that physically represents accomplishing a task with numerous side quests.
Yet, another example of amazing creativity, with no purpose or application
just like you have wasted your precious time by writing this useless comment
The mechanism that goes in a Sybian machine
Nah sybian is a different type of machine 😊
Traces a very interesting ellipse. I don't know enough about machines to understand why you would need something like this
Videos like this is the reason why I wished that I have a 3D printer
alternatively you can use lego technics, I constantly make things like these for use in GBC modules
for the linkages you can just use popsicle sticks and toothpicks
3D printers have become so affordable and accessible that if you want one, there are few reasons left not to have one. Go for it, you won’t regret it.
@@redfluxbluedawn414GameBubeColor ?
Not only is your work amazing, but my “random thought syndrome” came into effect when I suddenly thought: you would make a great Flynn Ryder for the live action Tangled. Keep up the entertaining builds! ❤
Hahaha thank you!
*the clitoris has entered the chat*
The 3D Printer Guys' new equivalent to stick bugging people.
Now to put a saddle on it to make one of those electric bull machines like you might see at some western bar.
The new Jerkomatic 2.0 looks wild
Looks like something Volkswagen engineers would design just to produce an overly complicated windshield wiper drive LOL!
Jay doing research for Rube Goldberg Project,
Suddenly, a worthy Chebyshev Side quest appears.
Jay conquers it without breaking a sweat!
And it's crazy like those dancing air guys..
😂😂 a little bit of sweating occured
used a Chebyshev in high school doing robotics. Its a cool linkage
Sounds like a fun class 🙌
@@Engineezy just a robotics club, we didn't have a class probably a good thing tho, as I always slacked off in the engineering courses bc they were easy
"Dancing Air Guys" uhh do you mean the wacky waving inflatable arm flailing tube men?
so it's like an automatic sign spinner
A couple of super long & subtle whip antenna would work really with that kinetic piece of art.
Reminds me of a rowing motion.
Slow when pulling, quick to get to starting position again.
Yup... that's a successful whoopie machine linkage.
Those are in surprisingly high demand...
Inlay reference numbers or marks or bumps to distinguish between similar looking members. This is especially useful if only one part needs reprinting so you have different numbers of different parts at different points in time.
I feel like a pair of them on either side of a rubber hose would make for the most complex peristaltic pump ever.
Can you do in-depth video of how you actually make it happen? Calculation wise too! Used to try to make it but fail miserably.
I’m very proud of you man!! Keep up the good job
Wow thanks Chris 🙏
@@Engineezy ☀️
engineers working as hard as possible to do anything they possibly can but create a practical solution to anything at all ever
This is the perfect movement for a PJD
Looks like something we used to have to analyze in Kinematics. Something like: Given rotational acceleration about point A, calculate the acceleration in the x-hat direction at point D.
Thank god people like this exist. I couldnt imagine doing that
Love the plastic chain. Would love to see more of this and build them into some sort of crazy machine / puppet or something.
This seems like a prototype for an automated catapult. Nice 😎
blud created the doohickey 💀💯🔥🗣️
I have a feeling that women would love this machine so much! 💀
That’s crazy!
🤪
Homelessness cured. Thank you. ❤
I like how it throws it back
Yeah that looks pretty confusing. Excellent job, That finished product is nice 👍🏻
Thank you 🙏
A tiny electric motor apparently requires a giant circuit board. So I guess this guy must be really smart. He knows about circuit boards.
If you turned that upside down, you could probably use it as some kind of mechanical robot leg.
Reminds me of a bird wing flap. Wonder if it was made a bit longer or attack a few longer rods to the mechanism then extend them out a wing and have the mechanism flap the wing. Idk, it looks cool regardless
Stick a tiny double pendulum on it! The randomness resulting would cool.
Who knew Jerry Seinfeld was so multitalented? I sure didn’t!
guys like him are the future of our country
I love it, the movement reminds me of a stickbug
Automatic Watch Winder will be a wonderfull case of use.
Love how he plugs a wikipedia page and talk about "research" like it does something that required research 😂😅
Scaled up, upside down with a foot on the end I feel like a few of these attached to a chassis would work as a means of creepy locomotion.
Damn my wife seen this and wants pane idk why is so excited, she never liked 3d prints
Она знает куда применить это вечером😂
Why does the camera pointing the desk from behind looks looks like from the 90s? I'm still waiting for Ross and Rachel ❤ great content ❤❤
Turn it upside down and use it as a walker
It reminds me of those really cool windwalker beasts.
You used your computer and the CAD program to work all of that out but can you imagine, in the days of steam locomotives, they didn't have any of that at all.
This needs a white sheet with spooky eyes drawn on it with an LED at the base.
What you have come up with is an example of a quick return mechanism, its not a four bar link.
Quick return mechanisms were common in machinery designed by mechanical engineers who specialised in the research area of kinematics. Old mechanical sewing machines used a form of the quick return mechanism.
Please research the area before building another one by referring to previous work by authors such as: Jeremy Hirschhorn, Ken Hunt and Jack Phillips. The research area was much richer 50 years ago.
You will need to establish each link's tangential, centripetal and coriolis accelerations at operating speed to minimise its operating vibrations.
The design of such mechanisms is not just based on potential link collisions but the motion that is required at different driving link angular positions.
How beautiful
😮 it’s just 🔥🔥🔥
🙏🙏🙏
there is a European puppet artist, he showed ten puppet heads, each moving in 2 axis motion. all with one motor. That was similar to yours but a step beyond.
Never heard of Rube Goldberg until now, but to me it was definitely Heath Robinson. Now I know that the two artists were very similar, along with a couple of others.
Wow, that is cool. And I love the dudes excitement about it.
Nice chebyshev linkage there
Dude....how do you edit all of these videos while doing all this?! 😮 I'd go insane. Please tell me you have an editor.
This is so fun and informative to watch as always!😊
I wish I had an editor! Just trying to find a flow that works!
My daughter : Dad, really, he's such a nice guy...
Me : But LOOK at how he holds that Dremel!🤦🏻♂️🤦🏻♂️🤦🏻♂️
You should make this into a puzzle. I wanna try to put it together without directions maybe just a basic picture that you cant tell how it works.
That's cool🎉 thanks for sharing!!
That thing should start the ball off with that flick
It's interesting if you put a linkage from the rotating and translating bar to some shape.
Orientating it at 45 degrees, it would actually make a good sysyphus's boulder.
When you mentioned needing to refer to your CAD to put it together: Would it be possible to add little icons or numbers on each printed part? Like "A->B" and "B->A" next to where two parts join.
Should extend the links past the bottom joints to look like legs and make a model horse running🤙
That’s 100% what this looks like to me
Anyone reading this who has kids I highly recommend GETting them A MECCANO SET!
Good job Howard!!
Really reminds me of "bashing your head into a wall in frustration" emoji.
Perfect for bed self playing with more sensitive parts of own body
2 of those side by side and have a walking device!
I've subscribed (came here from your clock escapement explanation), looking forward to your Rube Goldberg machine.
In the meanwhile, I'm enjoying the rest of your channel.
You remind me a little of Tom Cavanaugh the actor, in a good way!
:,)
Awesome teck man❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤❤😂😂😂😂😂😂🤙🤙🤙🤙🤙🤙🤙🤙🤙🤙🤙🤙🤙
he really woke up and though damn i should build a FREAKY bot
This might be useful for the rube goldberg machine if you mount a shuttle plate on top. I could also see a bunch of these being used to drive a conveyor belt.
Im pretty sure this comes prepackaged at "Adam and Eve", with an "extension" - "Pound Town™"
Kind of a random idea…but would there be any way to attach a paddle to the moving end to have it successfully row? Have the same machine/paddle mirrored to have it move straight rather than just turn.
with some attachments, that thing could really stretch some pizza dough.
Idk why vut this man is giving Harrison wells from the flash kinda vibes
Very cool! Must collect all the pinecones!
Can you show exactly how do you make the joints? I was building a klann’s linkage for a walker and I had an issue of coliding joints, but countersunk holes did not fix the issue, as the friction between the parts grew a lot
When the four bar linkage has like 12 bars
You don't really expect a clanking sound with the phrase "printed it out". This is definitely the future 😀
Is the movement on the chain constant/consistent? It might just be my eyes or the filming, but it looks like it slows down in bits and you may be losing a lot of energy
It’s like a fly fishing device.
This looks like it would make a good ball thrower
I was waiting for the stick bug to appear on screen.
