- Welcome to another episode of Scrap Mechanic! Today I am experimenting with recreating a mechanism found on a channel called @artofrendering . It is a cool bridge folding system that uses pistons to apply tension to bridge segments, causing it to roll up into a circle!

I love when scrapman comes up with the most random things in the middle of the video like swoosh
I smell scrap man Ytp.
and he also said venus fly bridge lol
hsoows*
We all love the art of rendering
Art of rendering should Collab with Scrapman :)
whats the art of rendering?
@@fejinantony7729 The Art of Rendering is the CZcams channel where ScrapMan gets his mechanisms to recreate in Scrap Mechanic.
Oh yup
You could prevent the piston misalignment by putting stopblock where the pipes would reach 90° so they can't turn more than that. So if it wasn't too heavy to phase through the blocks it should in theory work.
100%, unless the piston strength is also a problem.
I don't think he tried adjusting piston strength though, that might be the problem as well
might be simpler to add a stop on the diagonal beams to prevent the piston from 'clipping' through them
Couldn't a second piston do the same? Using a second set of logic and a second switch, have the pillars be an extended piston. When closing or having it open, they extend and just sit there acting as a pillar. But when he goes to try and reopen the bridge which the pistons don't have the strength to do, the "pillar" piston closes which adds more strength behind the pull to extend the bridge. Or would this not work? I don't have the game so I'm guessing.
The funny thing is, this is actually a bridge irl in london england called the "The Rolling Bridge"
i forgot who but some youtuber made it in poly bridge too
@@D33ZiE Probably The Real Civil Engineer. He builds a lot of bridges 😂
@@justjay4586 i was about to say that XD
Yeah that's actually the first place I saw that done too
@@D33ZiE Reid Captain?
if you make this in trailmakers, you can adjust the strength of the pistons and maybe work better? and then put it on tank base to make a insta-bridge builder!
Trail makers is hard to make physics based moving parts, good idea, but it would probably not fold anywhere near what you could get in scrap mechanic.
main issue in trailmakers is the lack of bearings. the spinning servo or rotating servo can work, but theyre just massive parts
To keep it from over-centering, simply make each yellow piston pillar into a T perpendicular to the bridge. Then it should unfold nicely as well since that's what locked it up, not the weight.
EDIT: Some are mentioning that a bridge like this exists, and it does! It's the Heatherwick's Rolling Bridge in London. A small walkway bridge, but a neat structure either way. It's clever how it over-centers piston-to-truss links when unfolded. This keeps it locked straight in case hydraulics fail.
this actually exists! its called The Rolling Bridge and its in London.
I remembered seeing a video of it but I always thought it was in Amsterdam. The one in London is a pedestrian bridge across a small canal iirc
yeah i think you're right
I think you just need to adjust the speed or add a sequence to the bridge.
I would make the first piece the fastest and the last piece the slowest and every piece in-between have progressiv speeds.
OR
You extend the pistons one by one and the bridge will unroll itself and won't need as much strength too.
I think the problem is that the last piece extended first and put more weight over the hinge (extending the leaver action) and the first piece wasn't strong enough to handle it.
I'm always amazed how much y'all still play with this game. Neat project.
I think I’m gonna go back and watch your first scrap mechanic play through. I love the castle you built around the garden and all the traps. Very entertaining series.
The way you managed to keep those hinges compact is amazing skills.
This gives me ideas on folding bridges to go to islands that aren’t connected by land to put a base on
Scrap man is the guy who makes the things that come up to my mind in 3AM
This is cool.
Your videos are awesome!
The center-folding bridge would make sense and operate like a swing bridge. You'd keep that folding up in the middle, but when unfolded it should rest on a column on each end where it should also meet flush with another bridge segment which may or may not lift/fold back to the mainland. This way boats would get the necessary clearance between each column and bridge to be able to navigate through waterways.
True, but its not exactly the most practical way to do it
@@Finat0 Nothing about the bridge was practical.
@@Shugo5775 your not wrong...
This is so cool i never seen a bridge like this
This is gonna be a great video I can tell
This unfolded quite nicely
To make an 8 segments bridge, you'd have to do 360/8=45 degrees angles on the segments (divide the whole circle by the number of sections).
For the unfolding and floppy problem, it comes from the weight of the bridge : the last piston only has its section to carry so it works, but the 1st one has the whole bridge and is not strong enough. Making the piston extend 7 or 8 blocks doesn't matter. You could improve it either by making the bridge lighter, or using 4 pistons instead of 2 per section. When it's welded in the center, it works bc it only has to lift half of the weight on either side.
Nonetheless, cool design and vid as always :)
You guys should have a multiplayer challenge where you all try to wheelie the longest.
Making a wheelie car is actually really easy and incredibly fun.
Like if you want Scrapman to see this
Ooo love a good build video on scrap mechanic.
YAY A NEW VIDEO!
My fav channel
this is so satisfying
that is a great bridge thank you scrapman
DevVsCreators idea- You can have a challenge of which team anchors more planes to the enemy planes within 5 minutes in Airborne expansion. You have 2 lives and if you die twice you can't put more flags. Inspired from previous video.
2 5 minute team rounds, then 1 last FFA round lasting only 2 minute.
Edit-Listening to the comments, I can say that it would be more of a FFA only vid where first to anchor plane (twice?) wins.
I don’t think 5 minutes would be enough time to anchor a plane
Good idea but in my opinion, it seems really challenging. It was hard enough for ScrapMan to successfully anchor to a singular NPC plane.
Scrapman: ...
The Art Of Rendering: Exist
Scrapman: I can milk this
Always nice with a new video
11:11 "Just Don't Do It" 🤣
Adding a controller to the bearings might help give it a little more force, and might allow it to unfold even after too much angle. It would take some tweaking to get it to sync with the piston movement, but might make it work closer to the intended result.
ha ha ha that is SO cool. Even though it didn't quite work out as intended, still an awesome creation!
Thats crazy because i just started making this exact thing in my drafting class yesterday 😂
I love all your videos
Hey scrapman, Have you ever tried poly bridge?
Maybe something you could do is put some sort of stopper on either side of the piston towers, perhaps between the ramp pieces that make up the truss structure so that might prevent the overextension issue.
To unfold the bridge on the attach left or right side, you can try the following:
Sequence de unfolding pistons, to unfold first the one near the attach section, remaining the hexagon tension, then unfold the next section, and so..... Because unfolding the last section will create more torque on the first pistons, and the pistons wont have the force to push the bridge
Yeah, this bridge actually exists in real life!
It's called the "Heatherwick's Rolling Bridge" and is located in London!
I hoped someone was going to mention it!
yeah me too do you think he knows?
Soo excited
I believe there is actually a footbridge over a small canal that works like this. Can’t remember where or what it is called though.
Yeah, it's in London I believe. Think Tom Scott made a video about it
@RCE needs to rate this bridge!
Amazing
I remember making bridges like this in poly bridge
I know a good British friend who loves this video and might call you a REAL CIVIL ENGINEER after watching this video...
Ah another R.C.E. viewer
If you attached the purple bits closer to the middle of each segment, that would prevent it from overextending.
Would it be possible to put a stopper in front of the piston to prevent overextension?
I was thinking a wedge block in that slot in the truss since that wouldn't really mess with the profile of the bridge, the bridge looked like it was locking up because the piston pylon was just freely rotating thru the gap
I think you could make it work from one end if you sequence the pistons.
Put some weight on the sections closest to the anchor point, then retract those pistons first and gravity should help it roll open. Think of a slinky where each part pulls the next over the tipping point
Since the bridge is currently balanced over the anchor, it has too much weight trying to keep it closed and not enough trying to open it
Damn. I would love to see this concept in Trailmakers.
you could put a block or a cone under the piston 'like outside below the piston) to prevent the purple pillars from going over each other. maybe that could fix the folding and unfolding problem.
It feels iligle to get to a video this early
I know you dont really revisit, so i kinda wish you woulda stood on the bridge when you had it attached at the end, and folded it up. Would have looked like that scene from Inception where she learns to manipulate the dream state.
RCE would be so proud! 🥹
Especially whit the efficient shape it has at 11:13 😂
@@sooshiant8432that is a very efficient space
I think this could also work if you used bearings to make sure the pipe pieces move in the correct direction instead of kinking the wrong way.
We have a similar bridge in London. It's called the heatherwick rolling bridge.
I think the speed setting of pistons also change their strength. Maybe try changing it to help your bridge unfold?
Can use a piston mounted on top to push against a bump stop on the next section not attached to second section so it only pushes like 1 or 2 blocks as your linkages are just over extending till gravity can flop it sideways is what it would be equivalent to irl
"Here we can see the Venus Car Bridge on its natural enviroment"
venus car trap
All you need is a spacer block to not let the bridge sections rotate past parallel with piston. That will keep the piston in the middle and able to retract again.
Hey Scrapman, I’m keeping a promise of never letting you forget what you said:
Mario says “it’s Morbin time”
Never forget.
Fun fact this bridge is real it is in London and it crosses a river and it folds up to allow small boats to pass through
Reminds me of polybridge
Now thats interesting
Buildsan awesome bridge never once thinks about using to cross the little valley nearby 😂
you should try a multiplayer monday where you make a track with obstacles like this for the others to get past.
Lmao Venus fly bridge. Following that I would like to see a piranha plant in a pot next to a road and when you drive by it tries to eat your car picking it up
there is a bridge somewhere in the UK I think that is this hexagonal rolling bridge design
This bridge is a lot of fun to look at but very mechanically disadvantageous. The pistons have to produce a lot more force at their extended position than at the retracted one due to the angle of the joints. I believe this would also fail in real life for that reason; the stresses would be too great for anything more than a short footbridge to survive.
If you put a block in between the wedges to stop the yellow bit from falling out of line, then with the piston pulling on a straight line it may unfold better?
Speed setting increases strength as well
There is a bridge like this in London.
Its called Heatherwick's Rolling Bridge
We need a bridge review where is real civil engineer when you need him
hi scrapman. would love to see you make the DUKE engine. its some fancy mechanics XD
I still want to have a video where Scrapman and friends just show what crazy stuff they have been up to, like who think Kan would lose his mind at the car powered by steering or even this bridge?
This concept is actually called "The Rolling Bridge" and its a kinetic sculpture located in london
And i love trailmakers videos
playing with this in ploybridge, it works, but not as well as the usual method of just having the top truss be hydraulics that compress. scrap mechanics can't have pistons that start at extended so i don't think you can use that method.
Crazy idea: choose a g1 transformer and remake it in scrap mechanic with a working vehicle mode
You guys should do a race where you do 3 laps and you have to carry your own bridge to get across gaps and have different lengths for multiple monday
I want to see them do a deployable bridge challenge based off of this have a vehicle that can put the bridge down drive across it and then pick it back up. That would be awesome.
Someone needs to send this to RCE, Real Civil Engineer
Scrapmechanic! Its been a while lol😂
it sure has
A folding room that folds up into a box like how we are taught to make them on paper
that bridge is actually a real world bridge in the city london
Can you see if it can fold up and 2 boats can go across the water and then unfold like a regular folding bridge would
The over-extension could probably be fixed by placing a block on each side of the piston, between the trusses
Amazing bridge design! You know why? Because its a hexagon. And you know what hexagons are made of? WEDGES!
nice
petition for him to play satisfactory again
When you do your new survival mode series you should make this the bridge into your base
Soo this video also gives us a fact that the wedges used are at angle 60⁰. As there are 6 parts.
I can adjust the time of unfolding of each piston.
It might work
hey scrapman, you set the pistons relatively slow witch means they are also weak, control them via controller so you have max piston power while maintaining slow speeds
Multiplayer Monday where you have to use these as wheels
Scrapman: *Has an ephiphany*
Me: What else is new?
Unravel: Ravel
Tooting your own horn: Ain't it weird to toot someone else's horn?
Make a road that has sensors so that lightposts only individually turn on when you aproach
Hello Mr. Scrapman. I was wondering may you create this aircraft in Trailmakers. :3
Sincere
Big fan of your channel.
I doubt it would be viable in Scrap Mechanic, but maybe in Trailmakers you should make a volex robot
It's a working bridge. It is just disposable. It works fine once, and then you have to build another one.
you should make a smaller version that is like a character trap when they walk over it it closes up on them
this is actually a real bridge! its called Heatherwick's Rolling Bridge in london.
Hypatheticly speaking could you make it into a moving vessel that wher if folds it is able to move and when it unfolds it goes into a bridge. I would love to watch that video
I believe the render is a render of a real bridge somewhere in Europe, I forgot where.
