I Recreated This Strange Rod Mechanism In Scrap Mechanic

Welcome to another episode of Scrap Mechanic! Today I am experimenting with recreating a mechanism found on a channel called ‪@artofrendering‬ . It has a strange rotational asymmetry where one rod rotates at a constant rate while the other has a sudden burst of speed. How easy will it be to replicate in Scrap Mechanic?

Sometimes if the paint is two different colors Scrap Mechnic does actually begin it's shenanigans and starts differentiating same, lets say wood, blocks into two different attached wooden objects. Helps with giand creations that always try to phase through reality.

[@Hadeks_Marow]

The problem is the good looking parts. Specifically the pole with a square base. It needed to be round, the square hitbox is getting the creation caught on the corners. Replace with a pipe piece and you should get MUCH better results. Also, you know where the pole is connected to the post (the end part connected to the wall that isn't in the illustration, off-screen to the right), THAT is where the piston shoulda gone. Basically, pretty much the same thing you did with the first piston attempt, only do it to the horizontal "output" pole, not the vertical "input" one. It will achieve a similar result with what you ended on but look more like the render.

[@TinchoFigue]

This! I was screaming for the horizontal pole to be moved instead

[@illuminagal]

Most of the Barrack parts have box collision, this why it works weird. Though cylinders have actual cylinder collision, they have default diameter of 3 blocks due to incorrect margin value.

[@user-es6wn6pz3e]

It's not only about moving one pole, in an ideal completely rigid simulation, that would be impossible; it also needs the angle between the poles to be slightly obtuse.

[@coolHawk_]

He also needed to add a block between those pipe brackets and pipes he mounted them to. You could see the piston in the S bracket compressing as the tab that goes into the pipe brackets on the output shaft collides with the output shaft. In the simulation there was enough space to allow for a >90° movement, which I suspect was messing this one up a bit.

[@SonOfmowgef]

What I'd really like to see is Scrapman going back over some of these mechanisms, but getting them to do work. Getting them to do something that would be useful in survival mode for example.

Its like while he explains, he shows what's he is talking about while simulating it! It's very useful to understand it.

[@pocketfulofgeese]

Need a 1 block air-gap at the shafts' bearing "ears". The animation has a gap to allow the assembly to go greater than 90 degrees back into the piston, but the blocks were pressing up hard against each of the shafts and were limited to 90 degree sideways movement as a result. The piston you put in the "S" helped address that somewhat, but I'm pretty sure it would work on its own without the piston if that was corrected.

That would be called a one-way rotary damper clutch. If anyone would like to know what it is called. Thanks for the shows Scrapman.

[@ArinJager1]

but what it does, though? I'm reminded of some kind of suspension or drive shaft or I dunno (not an engineer, just a humble scrapman watcher)

[@ducewags]

@@ArinJager1 Found on lots of things. Balers for hay and straw use the clutch for the pick up rotor to clear jams. Belt conveyors use them as a clutch in the event of a drive motor fail, keeps the conveyor from going reverse in a fail. One would not want to be on an escolator going up, and end up going down with no stop at the end. Soft close doors use them, momentary contact switches are also a good spot to find them. It's not just for drive systems as mechanical pens use the same idea. This Old Tony did a video some time in the past called "Rotary & Linear Dampers, what a drag". Well worth the watch just for the jokes.

[@Netherdan]

Doesn't the horizontal shaft needs to rotate as well? From the original mechanism I was getting the idea that it converts vertical motion into horizontal motion but he didn't allow the horizontal shaft to rotate so that's probably what was causing it to jam at higher speeds

[@ducewags]

@@Netherdan It would if the horizontal shaft had a bearing on it where it connected to the upright pipe, and not on the damper clutch side. In the real world that is how it's done. In cartoon land, not everything is done the proper way.

[@namish2727]

1:13 did you do this animation on the right?? If yes hats off to you brother 🎉

[@paragbanothe7111]

The editor did it

[@notonlyhuman6073]

It’s actually incredible that you can replicate complex mechanical movement in Scrap Mechanic

[@nathanwilbrink2444]

The method with the piston creates a lot of strain wich causes the vertical axle to flex because of the bearing and causing it to work (it could be better if you angle the axles instead of just moving them)

[@SnakeEyesOfficial42]

How you aren’t an engineer baffles me. You’re able to assess these Machines and builds very well.

[@cymortevaale2514]

Great Video, love this series of replicating mechanisms! I think using a piston to move the motorized pipe might cause some unwanted tension. If you consider that of one of the two joints controlling the vertical pipes axis has its fixed positing at the horizontal pipe, then it might make sense to not only do an "inwards" push, but to also push the vertical pipe down. That might be better achievable then by having two bearings lowering it and shiftig it aside at the same time. Maybe you can try that out in another video replicating a similar mechanism. Keep it up, great work, great quality!

[@moroblizniak4457]

I will never guess why such a slow pace videos are so enjoyable.

[@gamerxdpro9112]

All of the mechanism you made is amazing keep it up scrapman

[@SirJerric]

My read is that most of your problems are due to the relationship between input and output. As soon as the slight tilt was pointed out in the beginning, I realized that the output was more than 90 degrees off from the input. Your first piston at the base came close to fixing it, but you were pushing toward less than 90 degrees, so it struggled even after the jammed bearing was fixed. My solution would be to let the output pipe rest in a tall net block loop (no bearing on that end), and use a piston to bump the loop up one block. Bonus points for then adding a slapper arm beyond the loop to see if catapulting with this joint is viable.

[@akhmadasrori3819]

[@danielpodsiadlik3576]

You missed adding when it was glitching that you needed to slow down the spinning of the mechanism😅

[@danielpodsiadlik3576]

By glitching I meant what are you call “hiccup”

[@WorldClassDummy]

15:12, now put this in trail makers 😂

[@omgtntlol]

When you were talking about moving the mechanism over a bit, I was thinking maybe you could use some kind of old school scissor-type piston design to go less than one block while still being stable. But... you already know the drill Day *98* of asking Scrapman to do a Multiplayer Monday in survival mode where everyone starts at the crashed ship with a craftbot set up in the mechanic station, then everyone has 30 minutes to build a vehicle from scratch, no glitches, thrusters allowed, after which everyone meets up and races along some road :)

[@ManikFerret]

These interesting real world mechanisms made in scrap mechanic are my favorite by far seeing you try to figure out the way it can work in scrap mechanics physics is fun!

[@aaron_lycanlycan4065]

Never played scrap mechanic, but as a space engineer player I still have nightmares about rotors and pistons from when it came out. All hail the kelang god!

[@paganathiest6349]

if you added a pivot joint to the bottom you probably could've gotten it faster, a pivot joint would've allowed for the full extension of the piston at the bottom allowing for that 5 degree difference, also when you opted to have the angle difference be on the inside its not that big in scrap mechanic especially with controllers but that is an energy deficiency as it would require more energy to pivot from a 90 degree angle than it would a 100 degree angle. overall loved the video really got my mind working

[@johncage5368]

That was a tough one. Well done!

[@Blaster_Unity_UB]

I tried to replicate this in SM, but it kinda didn't work, mostly cuz of my personal laptop's performance.

Scrapman your a wonderful creator keep up the good work ive been watching your channel for years thank you for creating this great content

[@Leftysrev3nge]

That was extremely satisfying.

[@Sm0llar]

I assumed that you need to do alternate piston switching, but you managed without it, good luck in the future ✨

[@crimson3274]

The mechanism is so easy to make it took me few minutes to do it right.(i paused the vid when i just seen his try at the S bend. The rotation points align with the highest and lowest parts and the top shaft is actually slightly up. Moving it instead of the bottom shaft would force the top shaft to give under the motion making it do exact same quick spin at the highest point.

[@AoxTheGardener]

You know what? That was well done, man!

[@vlastasusak5673]

Let the bearing connection at the end of the driver rod be point A, and the bearing connection at the end of the driven rod be point B. Construct a right triangle with hypotenuse AB. It's arms are parallel to arms of the support frame. (There are two such triangles, let's consider the one where C points inside the structure) By moving point A closer inwards, side b which is AC is being shortened. Since c2 = a2 + b2 side c which is the hypotenuse is also being shortened. The hypotenuse is made out of a solid object, and thus cannot be shortened, and needs to remain constant. To shorten side b, side a must be lengthened in proportion so c remains unchanged. By doing that, values of angles at points A and B should switch, thus tilting the hypotenuse without compressing it. In practical terms, you need to push the driven rod out, if you push the driver rod in.

Thanks editor, really cool 3d animation

[@kellanliu9788]

omg the raichu in the background is so cute

[@yesseru]

I think putting the piston behind the vertical rod would be more stable, and be more like the actual animation.

[@Citizen5000]

In the beginning you explained what is needed to make it work, just extend the long pole with a piston first so it sits at an angle.

[@predur4136]

in my opinion there are two problems The first is that perhaps it was better to use an electric motor instead of a controller and the second that also the upper arm must be slightly beyond 90 degrees in starting point

[@Subtweeted]

Man that is so freakin cool

[@StephenHall-zz2ym]

Instead of adding the pistons, you could have just made the joints go a bit farther than 90 degrees

[@CarlAndreasMLLEVA]

Can we just appreciate the hard work scrap man puts in his vids?

[@kholdanstaalstorm6881]

I wonder why ScrapMan didn't put the piston in the upright support for the end axle, so everything after the first joint was lifted up a few degrees? That seemed more in line with the animation than the piston flex in the S bend construction. I'd try that if possible, should be a quick test for ScrapMan on the next mechanical example test.

[@noelradhakrishnan4423]

Props to the editor

[@MrAXEL2181]

glad to see that got it to work but i would have tried the piston on the output axel first to push it left instead of the generating axel pushing up but hay it works and looks good

[@lesto12321]

i wonder if the horizontal rod, instead of being on a bearing, could have been "trapped" in an Y shaped that is 1 block lower. this way you would have got not really 90deg, and the longer is the Y in the horizonal rod, the lesser is the angle. But i guess when it does the quick flip, that is a high torque maneuver so it probably want to jump a little

[@mossie7920]

Kinda hope main assembly will be back on the channel one day.

[@Krokmaniak]

One big problem I see is that long rotating pole is constant lenght. When piston is offsetting it it doesn't change lenght and geometry of the system is keeping it locked close to 90 degrees

[@simenkolas9373]

the sideways piston on the first pole makes the pole colide with the blocks under the pole.

[@I_DontKnowWhatToPutHere]

Try putting the piston on the horizontal tube piller and extending it by one block instead of the S bend.

[@achyuta8480]

Keep up the nice work 👍😀

[@dawnnightinger3025]

Just make one part of the S bend heavier than the other. The weight will push one side down easier allowing it to work faster.

[@kharn2472]

its interesting, scrap mechanic actually makes you think think like an engineer, funny story i tried simulating a German puma steering using warthunder on as a reference but scrap mechanic did not like it, it was system with piston and angling the wheels but i just couldn't figure it out

[@crustybomb115]

square base on the good looking parts gets in the way of the mechanism moving the way you want it to... you can fix it by removing them and using regular pipe pieces instead...

[@QuirkyView]

Sitting here watching you trouble-shoot, staring at the problem (the joints attached to the rods need to have more than the 180deg of possible movement they have), hoping you'll see it before the video ends... He made it work regardless of that problem lol

[@d.j.nijholt5030]

Nice work! And yes, it looked good. You should check out the Brick experiment channel. They make useless machines with lego. Maybe you could recreate some of those.

[@Sawyer_Otto]

hey scrapman if you put a piston on the rod that spins freely and make it push towards the powered rod will that work?

[@dergus8833]

Look up "mathematics | trajectory of the slider" and it comes up with a very satisfying machine

[@LoafOfTheMilk]

I like these videos

[@picklesteve2313]

I think the issue was the bottom rotating axle was offset the other direction going to the left, and it need a bearing so it can rotate in the the axis your pushing it

[@queenofgeese]

Watching this video was a mixed experience. I knew the solution the moment i saw the problem and I had to wait 10:44 for you to figure it out. good video anyway, keep on going!

[@hypelivingdead1875]

Imagine making a vehicle of some kind with it

[@khzhak]

Did anybody else notice both pieces attached to the S shaped piece aren't spinning in relation to it, they're oscillating? Like 180° clockwise, then 180° counterclockwise. If you put some paint on the outside, you can see it.

[@chrisdietz8017]

15:38 yes almost perfectly aligned with the original.

[@dazley8021]

I think your contraption could be tweaked abit by putting those braces one block above the plate they sit on, to allow the hinges to bent past 90°.

[@Scrap_Bros]

Hey scrapman the reason why your piston could not spin correctly is because you need to add a free bearing behind the piston attached to the plateform and make it enable to spin when it pushes that way you can have it ben 2 or 3 block

[@daaavie]

I think this is where Stormworks might work a little better due to better physics. Also: Day 1 of asking Scrapman to play Stormworks.

[@thefaulnt3562]

A mangle rack is theoretically possible in Scrap Mechanic lookup the mechanism notice it can be built to a lego build grid

[@s.s.j5046]

Big success !!

[@IdrisVanNuffel]

I think that if you lengthened the back support by one block, in height and in length, using a piston you'd get a better result.

[@kashyaptandel4678]

the editor could’ve just used the clip of the problem happening in scrap mechanic only but decided to make a f-ing animation💀

[@cool_capybara3632]

heres a link to a video i found kind of showing how it works kzbin.info/www/bejne/bGTPmaibgrZ1i80

[@Kickerofthetar]

The fact that the tip of the 2 (it's a sideways 2, okay?) can't flex further than 90 degrees definitely didn't help this. That's what caused the pistons to struggle so much. They had nowhere to push that side of the creation, and they need to be able to split the difference to get the angle right (well, I guess they don't *need* that, since you got it working, but).

[@kito2949]

Lol, I tried to do this myself before watching this video, in a super simple way, and when I tried to record it, it crashed my GRAPHICS CARD DRIVERS, like completely, I even had to restart it manually. And I managed to replicate this by putting a piston on the middle vertical rod, and a piston on one of the side middle rods, if I can record it I can post it to the scrap mechanic reddit if someone is interested.

[@irawilliams920]

the rager's tools mod adds a jetpack, which should make these types of builds a whole lot easier. because you don't have to use ur lift to maneuver around the build.

[@lillappy7520]

To fix the issue for that problem apparently @wo0dy apparently show that the bottom part MUST be replace as a suspension as that is the thing to fix it

[@mrhendrixin4259]

yo, what is the music that used to play when the contraption worked for the first time? it was kind of a techy song, like when the watch mechanisim thing worked or the strandbeest thing took a step

[@WillDa713]

Around 5:40 you are actually completely correct my man, paint HAS been scientifically and empirically proved to enhance a machine's capabilities. Take red vehicles for example, clearly their bold and strong color is the determining factor in their performance and so is the grey paint you're applying to your contraption. I'm sure the clean, fresh out of the factory look will help you figure out the ins and outs of this design. Keep up the good work my friend, thanks for the upload

[@frankdeson]

they dont have enough room to actuate back at the ends thats why they snap and stop they lock at 90 degrees and negative 90 degrees in the diagram they go over 90 and negative 90 at the ends you even notice the weird bend in the start

[@ieatsoap6389]

what if you try to extend the s shape with a suspension at the end of the piston for flex?

[@lhgt1324]

You need to angle the pipe number 1 that you started to bend the other direction cus the angle of 2 output and input has to be greater than 90°

[@randomcarguy2543]

Thought this was a mig 23 landing gear from the thumbnail for a minute lol
