5 Ways to convert Linear Motion into One-Way Rotation | Lego Technic

Hi,
in this video, I have collected a few ways to convert a back- and forward-movement into rotation.
I hope you enjoy watching and get some new ideas,

Funny that you decide to make this just when I really need it. Thank you!

[@protoborg]

What could you possibly need this for?

[@BBonsteel]

Great video! Thanks for sharing. I'm hoping to build a few small inventions for a local children's museum and these sort of resources are super helpful.

[@scuffedroller2298]

This is cool! You should also do a video on some practical uses for these mechanisms!

[@Shabazza84]

The stepper is cool for switching gears. Including via RC. Neat.

[@test-kz2iq]

#3 was exactly what I needed.

[@Commander_Raveth]

This you must show to a teacher that still believes that one's child must not play with toys at any point in school. Because this educates more than a guy or lady swinging around their knowledge being convinced that theirs is the only knowledge that matters.

[@yorgle]

So i'm sitting here with my shelves of Lego creations behind me, and the sound at 5:09 made me think something fell back there. :D

[@in1]

Yeah I know that problem :D

[@SpacedHawk]

The parallelogram made me think of the mechanism in my clicky pen

[@Wolforce]

Hey there! Is there a way to make a steering solution from a continuous motor? I have some motors and I'd love to make a car, but they run continuously so its not easy to steer without the engine tearing itself apart.

[@in1]

Hi! I actually do have a video about that, it's not perfect for the motor, but it works: kzbin.info/www/bejne/kH_TlnShjNunfq8

[@Wolforce]

Awesome, thanks

[@mikelcepedagutierrez5310]

You can also buy a lego servo motor

[@MuscoviteDN]

There is another usefully sample. Great!)

[@mikelcepedagutierrez5310]

From where do you take that amazing ideas? they are so cool and useful

[@heho1]

Fabulous ! 😊👍

[@bdw4162]

Wow that was really cool 👍

[@Rainstalker]

Wow that was really cool👍

[@maksperme1653]

The last one helped me at my lego rev up launcher for lego beyblades design. Thanks it works so good. I gave some gear ratio and it is so powerful.

[@in1]

Glad I could help :)

[@maksperme1653]

Thanks

[@derpious267]

The gear rack 2 may help with my pinball machine build thanks

[@rs411]

賢いなぁ。 ギアの嵌合はバックラッシュなどが懸念されるけど、シンプルな機構で学べる点が良いと思います。

[@DrSteve1337]

This is great! Can you please also give a part list for the fly wheel? I really need this, because I think it is the only way presented here, to also turn one way rotation (as usually provided by the actuators) into linear motion.

[@in1]

Didn't want to upload it on Rebrickable, but here's a screenshot: imgur.com/xFiT519

[@dawidkomora3534]

1:51 damn that's a stress relief technic part. you good bro?

[@webhead5263]

I th I need it would be cool to combine #2 and #3

[@elesystemic6742]

Or a second one and a fourth one are also full wave bridge rectifiers that create rotation from linear motion. I made a full bridge rectifier

[@tomiivaswort6921]

actually, rotation is linear motion, but it changes directions around a center axis as you go

[@puzzleditlego2615]

5:52 looks like Mr crabs from spongebob

[@KycenPetersen]

The first one could be used in a typewriter

[@kubanek0958]

Big brain

[@whiteshadow943]

Can someone explain to me how the first one works?

[@JoaoPaulo-um5gx]

😊

[@user-qm9vi1kj2v]

Can you make the car lift simple and small?

[@InsensitiveUncle]

You can probably use these as a ratchet to

[@anthonyouellet98]

That’s what I was thinking

[@janbeznoska]

can you make fullauto gun mechanism using motors

[@elesystemic6742]

Maybe a second one is a full bridge rectifier

[@seanhenke5846]

Number two at the end is literally just a car engine made of Lego and a lot simpler

[@seanhenke5846]

Thanks on the heart just your

[@seanhenke5846]

Hi thanks for the heart just your average person going around you to looking at things in his recommended section being completely 100% objective

[@mathiasbrio2105]

Unless there is some lag of some kind I am first to comment

[@savoirdonner3272]

Hi where do you buy all these little pieces, what is the name in english please ? This is just great for testing

[@in1]

Lego Technic, is that what you mean? If you need specific parts, you can use bricklink.com, else you can buy lego technic sets

[@savoirdonner3272]

@@in1 Thanks , kind of any set ? I see a lot of them but to build specific pieces Anyway, I am doing dow wheelchair and you just save my life with your video

[@TDM-real]

i possibly make a machine with that to create a litte bit of electricity

[@in1]

You can just rotate a power functions motor, it's not good for the motor but it actually works

[@fairytalesworld2412]

Me too

[@ChickenmakeEditz]

Hello can you please share the link for these parts so that i can purchase then please share the links in my comment reply

[@elesystemic6742]

You need a sun and planet gear

[@OptiPopulus]

The 2nd one is two way rotation..

[@Jadg.pz.kpfw.CC64-2M-Jumbo]

Dats alot of bricks, i don't have.

[@testsubject5337]

Y’all were off the hook til now, some of these are extremely unreliable and if used in bigger sets would need need to be tended to very often
