[@Osono2diWorld]

Engineer: “after 100s iteration I’ve designed a mechanism to achieve this exact function” Scrapman: “I don’t know what this purple piece does let’s just delete it”

[@LordDragox412]

Scrapman: If I don't understand it, it must be wrong.

[@rotorwing9987]

To be fair though you could still call it "redundant" because it only accentuates the motion variation. It's kind of just chaining two conceptually similar mechanisms.

[@Leadvest]

To be fair, the implementation depends on the application. Here the application might as well be the prompting of KZbin comments.

[@knightbeforedawn]

The purple piece that you removed only increases the speed differential between the 2 directions of movement.

[@malbyx]

got me thinking, perhaps the original render is wrong? should that "floating but supposedly fixed" point could have been attached to the structure below?

[@platypuslord2399]

Yeah it was 100% for speed adjustment purposes and without it the speed isn't smooth on each direction.

[@132gameover]

I don`t know if I`m seen things, but the platform appears to be asymmetrical

[@anteshell]

It makes the speed constant instead of gradually accelerating and decelerating. At least on the slow direction. I'm not sure about the fast and I'm too lazy to calculate it right now.

[@markiplieristhebestpizzato2743]

Could just be to make it easier to see​@@malbyx

[@marqsande]

I believe the purple part does indeed affect how this mechanism functions. I think it influences the speed of the teal part. Without the purple part, the teal part would be rotating at a constant angular velocity, but the purple part makes it rotate at slightly different speeds.

[@simenkolas9373]

u can also think of the reaction between the dark blue and teal an exagurated version of the reaction between the pink and teal parts

[@stevenmcarthur7665]

Bros spitting facts

[@35manning]

Whilst it's not shown, the teal piece would be connected and fixed in place. Think of it as a crank shaft (which it basically is). The teal arm connected to the purple piece is offset from teal arm connected to the blue piece, with a round section in the middle. The yellow base frame should extend upwards and connect to the teal piece like a connecting rod with two piece bearings. The teal piece then functions as constantly variable transmission as the purple drive arm rotates through 360 degrees, which amplifies greatly the speed differential of the platforms directional motion. And yes, I spent way more time than I should have explaining this because I desperately need you to make a follow up video where you do it again and compare the two versions, before personally thanking me for inspiring you and serenade me a heavy metal cover of "Row Row Row Your Boat". Sorry, the fast and slow forward and back motion reminds me of the movement of a rowing exercise machine. If you are still reading this comment. Please pretty please...

[@ClayInvictus]

Pretty please read the comment above.

[@bluestonecreepr]

agreed?

[@atacstringer8573]

That piece that he removed would not function in real life there is no place for it to attach to because it has play rotating bar on each side of it so in a real life application that piece would just be popping all over the place

[@35manning]

@@atacstringer8573 millions of internal combustion engines would disagree with you.

[@atacstringer8573]

@@35manning with what part because if you're talking about that missing piece if you look at that original rendering the focal point is that a different spot then the peace in the middle making it physically impossible to have anything that would hold it in place like the rendering is showing if you can actually build this in real life and it worked like it does in the rendering you would be a magician because that's not how physics work and the only way you can convince me otherwise is with a physical model I am open to the idea that I could be wrong on this but I highly doubt I am meant this case

[@KaneyoriHK]

I mean, the extra bit is there for a reason, could've, at least for experimentation's sake, tested it to see if it would work better or worse with the purple piece

[@159asmos]

he would need a though barring. i think the challenge is to do this in vanila. at the end of the day, the deleted piece is functionally the same. as the entire thing. so it just double ups the effect.

[@glenjamindle]

The slot in the blue piece is what changes the velocity in the entire mechanism. It creates a delay while the purple piece maintains a constant velocity. Also, the blue piece can be one piece

[@Scratchydoesmusic]

*luffy jumpscare*

[@vibaj16]

how can the blue piece be one piece? You mean using suspension?

[@glenjamindle]

@@vibaj16 The central point that rotates on axis serves no purpose. Eliminate it and you have a single slotted piece that will still rotate the same.

[@vibaj16]

@@glenjamindle what central point? What do you mean?

[@gbyt034]

2:38 the teal piece is blocked by the purple and would not just slide down

[@sengir3937]

You need the purple lever to make a more linear movement.

[@ShawnHCorey]

I don't think so. The purple piece moves at constant speed. Because it pushes the teal piece close to its axis for part of its rotation and farther away for the other part, it varies the speed of the teal piece. This varying speed causes the slider to move faster in one direction and slower in the other.

[@barnabasigari3109]

​@@ShawnHCoreyyes but there is another sliding piece in the mechanism. They are constructed in a way that the non-liniarities cancel out (more or less)

[@clashofcraft9725]

lmao, I've seen this channel yesterday and thought "lol Scrapman has not done these things in a while" and here we are lmao

[@0bsidianPrime]

Scrapman you have pained my soul. The animation doesn't show it for clarity about the rest of the mechanism, but the teal part *IS* fixed. Also, this is a quick return type of mechanism.

[@spray_cheese]

7:08 scrap mechanic witchcraft never ceases to amaze me. I was not expecting that😂

[@TupperGamer28_90]

nice

[@username_mihai]

Scrap Man, next time you have to build linear moving mechanisms, just use 2 pistons. How to make this work? so: make a 1x2x1 platform out of blocks, place 2 pistons side by side on it, max their distance and speed. Next, build, while on the lift, on top of them another 1x2x1 slab so they connect. Last part is to get 2 logic gates and set one to NAND, connect the AND to NAND so that NAND is always on. Connect AND to one piston, and NAND to the other. Voilà, hit them with a hammer, they would basically slide with 0 friction. This would help so that your creations stay as one piece. You can also stack them for more reach. Guys, if anyone read this, please like so it gets to him, would save so much glitches from happening.

[@LuvLikeTruck]

I like your funny words magic man! (Actually I only half understand what you said but it sounds like it might work)

[@username_mihai]

@@LuvLikeTruck well you have to follow each step, and it does work 100%, used it many times, basically what those 2 connected pistons do is fight with one another, one always wants to extend and another one always wants to be closed so they each cancel out resulting in no resistance. Basically hammer go swing in them and they go woosh

[@LuvLikeTruck]

@@username_mihai sorry I wasn't clear, I don't play scrap mechanic, just watch some videos. So with my very limited knowledge it sounded like you had it all thought out. Cool it works!

[@mr.person5209]

Simplified instructions: place two maxed out pistons beside each other and connect them. Keep 1 on and 1 off.

[@username_mihai]

@@mr.person5209 I mean.. yah, that would work as well 😭

[@MattDvc]

The purple part reduces the acceleration time and makes the platform speed almost constant

[@Greenphantom301]

when it was turning at a faster speed when the light blue arm was on the bottom it couldnt push the weight of the sled fast enough and gets caught for a sec, then the controllor tries to catch up and speeds up until it has reached the point where it should be. thats why it seemed so agressive when it stopped.

[@NotYurpio]

[@palfly1864]

Would love to see you make a vehicle with amoeba wheels in scrap mexhanic! They're really weird shapes that somehow manage to roll. You will probably need one extendable piece due to the inaccuracy of the build grid, but with that it should work great

[@MerryVideoGames-pe3tp]

I glad you got back to this scrap

[@bradbowers]

the offset of the second "redundant" piece is the contribution to the bigger speed change. the purple piece slide in the redundant piece closer and farther from the center of rotation. which changes speed. The original had two speed changes.

[@lukeirvine1386]

Loving this type of content. Keep it up brother.

[@toddabbott781]

The second slide you removed accentuated the speeds even more... making it slower in the slow spots and faster in the fast spots.

[@DS-tj1xf]

You could possibly add more mass to the bottom of the purple platform to try to balance the “rocking” motion. I’m not sure if scrap mechanic physics would create another problem but it could possibly help. Loving these more technical scrap mechanic videos!

[@michamusiatowicz6772]

You should replay a bunch of dogfights on the high seas map to revisit them all with a twist.

[@golden.raja_]

mate you got a spelling wrong, edit it (it's twist)

[@AlrenClan]

That was a typo, thanks for pointing it out tho I’ll correct it.

[@barefootalien]

I think that extra blue linkage you deleted is there to make the movement very smooth and linear in the slow direction. This is probably part of an industrial machine meant to move an object while it's being worked on at a constant speed, then it shuttles back to the start position to get the next one. A lot of these kinds of linkages are super cool but not really used anymore, 'cause we just don't need to. When you have to use a huge steam engine to run the entire process, you need lots of linkages and machines to get the movements you need. Now we'd just use a linear actuator, maybe with a ratcheting mechanism for the return to be faster. Easy-peasy.

[@DanielleWhite]

I've heard the style of mechanism called "quick return" and the common use I know of is shapers in machine shops which do all of their work in one direction

[@Maxwell_Kenway]

Funny thing is that a couple of days ago I stumbled over his channel too via YT shorts. Interesting concepts for sure.

[@zodiakgames]

For some reason these are my favorite videos

[@AI-it3bo]

Yay, enjinir scrap man is back!

[@Loop_Kat]

If you take note of the purple and turquoise pieces at 2:26, you can see that the turquoise piece is not centered with the shaft of the purple piece. The purple piece also only passes through half the length of the turquoise piece (not counting the center bit), whereas the turquoise piece passes through the entire length of the dark blue piece. As such, it seems like the turquoise piece is acting as a sort of 'gear ratio' (I'm not sure of the correct term) between the purple and dark blue pieces, allowing for the more fluid motion of the original configuration In other words, you broke it before you even built it, lol

[@FireHawk9463]

My favorite thing is to sit down, eat some cereal, and watch a scrapman video😊

[@jeffreyblack666]

The purple and green piece make up 2 stages for speed differential. If the rotation of the purple and green where aligned, then they would go at the same speed. But because they are offset, their relative rates of rotation are different. When the purple is pointing down, corresponding to the slow motion, the distance from the centre of the green to the pivot is largest, meaning the motion of the purple will have a small impact on the motion of the green. When purple is pointing up, corresponding to the fast motion, the distance from the centre of the green to the pivot is smallest, meaning the motion of the purple will have a large impact on the motion of the green.

[@SuperPeter05]

You need to make this with all its parts, even a short would be good.

[@user-lw2nb7ut1g]

Cool idea you should use the power coupling as a plane hook for the aircraft carrier

[@Jack_Wolfe]

4:05 the purple bit is actually to cause a pause at each end, it also stops the motor tearing the mechanism apart, you’re right about the fixed point, but for demonstrating purposes it’s removed so you can see it working. But that’s real world friction.

[@Darkenrall1]

The ratio of the light green part to the blue part is the same as the purple part to the light green part. It's like two asymmetrical stages of acceleration. An interesting part that is not shown in the video is that the sliding platform also has a conversion of force and speed like a gear system, when moving slowly it moves with much more force than when moving quickly.

[@KanaoTempest]

finally we are back with mechanisms

[@user-qt2zg4gq3w]

You should do a video where you make old historic modes of transport into functioning vehicles in Scrap Mechanic. Ex: Horse and carriage, pirate ship, da vinci tank etc...

[@LinkLaine]

for cool mechanism like this game should have a sliding parts just for avoiding collisions (because games still handle that pretty badly) and that will be much smoother and alot faster. for example stormworks have parts like this and i used it for folding ladder

[@dubl33_27]

I think the purple part in the animation is what allows it to slow down towards the middle of the beam then pick up speed after that

[@SuperDantedmc]

I wish I knew that life hack ages ago T_T Thanks scrap man

[@callumreynolds2812]

In the next mm if you are building, you should try encorporating this into the build to create a moving platform

[@Roxynoir1]

scrapman i dont know why but you give me the nostalgia of summer 2019

[@Eternal_Night69]

I wanna see a base centered around mechanisms like these(from that channel) to move around

[@bulletproof1581]

Hey Scrap man, the reason for you not having a smooth motion at a faster speed, I think it's because of the piece underneath the platform not being long enough, I think the bar simply needed more room to slide back and forth that's all :)

[@grantarmstrong2968]

I’d actually recommend checking out some Lego mechanical creators (for example, brick machines) because they also do a lot of mechanisms that are on a building grid, making them a lot easier to transfer into a game with a building grid

[@calebjardine7]

You can make sliders by compressing suspension and turning the strength off. It's not as easy but it stays as one part and might not break as easily because it will pull back even after it's out of line.

[@Chew00012]

Great vid! Btw if you flip the mechanism upside down it would act like a leg for a robot! Might be something to make a vid about?

[@wiktorbednarz229]

this gives me an idea and also i wanna try this too

[@dylanwatts9344]

You can use the light blue section to make a wall that lifts and lowers so the slow direction is the only passible direction.

[@thetrueminecrafter8091]

You could fully use this in challenge mode by building a platform away from the mechanism so that there’s just air underneath it instead of a platform

[@commongaming4797]

I wonder how people think, "Oh yeah, let me link a bunch of rods together to transform rotational energy to a horizontal movement." I do also have a video idea. You play minecraft and see if you can make doors (with pistons) and logic gates. I think watching you tinker around could be funny.

[@drewlucas6266]

Maybe a few suspension glitches on the platform can alleviate the issue of the platform wanting to rotate and snag on the rail. Some wheels could help as well.

[@akaEch0]

If you wanted to make this into a platformer map, all you'd need to do is offset the mechanism into a wall, instead of using a singular solid rail, use 2 seperated rails with a fall in the center and that's it.

[@randomthepyro2058]

the reason it was rough stopping at the higher speed is due to the peg slamming into the bottom of the slot on the sled portion. if you extended the slot on the sled, it should be smoother

[@codeyds6769]

You should try to break the sound barier using the rotating servo in trailmakers

[@Jack_Wolfe]

11:21 needs a block or two longer for the sliders pivot groove

[@PollexTheCat]

The purple piece makes the green piece change rotation speeds through it's cycle. It looks to me like the Groove in the center of the green piece is meant to be put through a hole in a support piece that's just omitted from the render to avoid visual clutter so you can better see how it works.

[@JonahBater]

My first thought was some sort of battering ram, or on a larger scale it could be used to load a giant gun

Hey in trailmakers you shoud try building the 81 that was a oblique wing plane prototype built by nasa. I think its a very interesting plane.

[@NoName-mv3nk]

Hi Scrapman! When using the low friction block it is preferable to have a rail like design, by placing two parallel bars of blocks, then on the module attached to it limit to two points of contact at each extremity, that should help alot with the jankiness you experienced. Have fun oh and if you want a low friction rail for a map lemme know ill share u a file

[@deadmax5730]

It's a variable automated ham slicer feed mechanism of many use cases

[@DarktideVtuber]

2:45 im certain you prolly figure this out but it helps assist in the speed change.

[@roccov3614]

Scrapman: "I don't really know how far down it needs to go. We can always adjust it." When you were testing it, it looked like it was slamming into to bottom of that piece. Maybe you needed to make it longer.

[@3ideas1channel]

6:13 whenever I make a machine like this the same issue happens Explaining it: so the problem is that weight and friction cause help stuff like this to happen but as it moves around when it gets stuck there it’s because it’s the least stressed point and if you were to keep moving it you would need to add another force to help move it from the lesser stressed part

[@leeik2155]

MP Monday idea - each person make a death run course where the creator activates traps and moving platforms in the back rooms with a view on the course. Similar to what we had as custom maps for good old counter strike 1.6 death run!

[@noonespecial_NOS]

Hey Scrapman an idea for either Scrap mechanic or Trail makers (It's been awhile since I've played either of these and have forgotten the extent of what you can do so this might not be possible) But anyways the idea, have you considered doing a team race where both people make one half of a vehicle that you combine together to make one full functional vehicle. And maybe to make it more interesting each member controls only their half of the vehicle. (Hope you haven't done this before)😮

[@TheEclipse1989]

Wouldnt making part of the sliding platform frictionless block be even better? And maybe the parts where the pipe pieces slide through aswell? Just a thought😅

[@anteshell]

6:57 You have to make a dedicated video about this. I've never seen this before even from Kan. Does this work on everything welded to the ground? Could I use this to pick up my survival base on a lift and move it elsewhere? 1:42 Their redundancy is dependant on the motion you want to achieve. The additional red pivot arm makes the speed of the platform constant instead of gradually changing speed like sine wave. Other than that, there's no difference.

[@TheBingus123]

I have an idea: Whose armored patrol boat can survive two submarines on the high seas map Edit: Thinking about this more, it’d be better if the subs wouldn’t be able fire their weapons from under water

The other part causes some speed changes, but there is no way to mount said part, at least not in that configuration anyways.

[@TheGrandBlade6456]

When it shoots back in its fast motion if done correctly it looks like it could make a catapult and you could even put a toilet on it and launch it

[@buckduane1991]

If you found this device interesting, ScrapMan, you should watch Hyce’s videos on how valve gear works on steam locomotives. Stephansons, Walshirts, autoINcorrect messing it all up as I type… it’s all very incredible and a lot more intricate than most people realize.

[@BleachWizz]

6:09 - so do you see the animation? when it goes down it kinda accelerates too much and snaps back. acceleration means force! starting to move too fast like that means you're kinda pinching the mechanism. probably it would be nice to "enlarge" the circles to make this part of the movement slower and smoother. "enlarging" the circle means the pin is pushing the light purple bar side to side, when it goes to the bottom it's getting too close to the light purple bar's center, therefore it need WAY TOO MUCH force to keep pushing or count with kinetic energy to skip that part.

[@crazynachos4230]

7:15 that literally worked perfectly

[@Phlarx]

While I do agree with the other comments that the purple piece shouldn't have been eliminated outright, I do think it would exacerbate the jerkiness issue, requiring that the whole thing be even slower. It looks like, with that piece in place, even more torque would be needed to run the input at a constant speed, and the torque was already maxing out without it. (You can see the input running at an irregular speed before he slowed it down).

[@john_duncan]

maybe you could use it to launch something while it is doing the slow wind up it may give you time to put a part on a cardboard and remove the cardboard so it can launch.
