Wouldn't really need this though. Geneva mechanism is mostly used for the winding mechanism, to stop it from being over wound or unwinding too much because when the spring is really wound or really unwound, the power it provides is a decreasing curve, in the middle is when the power is relatively linear and constant. All it does is prevent you from winding the last round and unwinding the first round of the watch. I don't remember if we have clocksprings in scrap mechanic but if it's powered by an engine, we wouldn't need the Geneva mechanism.
I have never played main assembly but from watching scrapman play, the structure in main assembly seems very fragile, like when things collide, they are not rigid but more like paper and they will bend
I can't express just how much Scrap Mechanic has awoken my inner engineer, no other game has gotten me so invested in invention and mechanical physics, yours and a couple other RU-vid channels adding to that greatly as well, having a great time with it all
It would be very interesting to see this mechanism used in a creation. Could you try making a clock or film projector? (Film projector doesn’t have to be functional, but if you want it to, just use a green screen and fake it.)
You could probably use something like this to recreate the timed firing system they used on planes in world war 1 to shoot in-between spinning propeller blades while still being able to line up shots
Not how it worked at all. Those planes didn’t have actual machine guns. They were fired by the engine, and had a semi-automatic natural cycle with the only thing actually repeatedly triggering the mechanism being the engine itself.
Scrapman, since the theme nowadays is Mechanically Mechanical Mechanisms, I recommend you try to make many other Mechanical Mechanisms. I'm pretty sure mathematicians and knowledgeable people will like it
You are single handedly getting me back into creating things. Your videos are so fun to watch and the mechanisms and history behind are entertaining to learn about. Thanks for being you!
You could use this to make a giant ammo loader, a rotating turret so one side shoots while the previous shot reloads, a weird walking mechanism, and several other things I can’t think of
Do a multiplayer Monday where you all build cars in trail makers that can pick up and throw barrels at each other. And maybe you can use the spawning mod to get more barrels.
My highschool had a theater that used reel to reel machines. I got to help the technician fix the shutter on one of our machines and he told me about the geneva drive on it. Cool stuff.
Slight possible improvement to the mechanism: Set the suspension stop mecanism in two suspensions instead of one. You see, right now when you lock it in, it pull down to go in, so at higher speed it might still have it down and create the problem. If you have it in another suspension (probably with a bit higher stiffness) it will stop earlier. It would still go down with the piece that is being unlocked, thats why im not sure it will work, but it just might.
In the beginning of this video it looked to me that scrapman started using a specific tile, an island on wich he builds his contraption and I really liked the idea because it would look much better for the viewer so i wanted to share it
I think the problem was the blocks sticking out from where those pipes were, which were causing the unpowered wheel to spin when it wasn't supposed to.
The fact that you can use wedges to make an actual ratcheting mechanism is amazing and give me some ideas fo when I get a new PC and hop back into my survival world.
The filmversion is specific called 'malta cross', a adeptation of the geneva mechanism, patented by Thomas Armat in 1895.The odd thing is that everyone just refer to 'watchmakers in the 17th/18th century', at the end of the line its most a story of who patented it and became the known person (like the original photograph etc), dispite there were more people before that time coming up with the idea. If you search on those, with oppositite lock mechanism, you can find a version without the circular center bit to lock it, but a opposite pin that slides in the moment the rotator pin comes out, locking it in place for the duration. Scrap Mechanic wise, that should work.
@ScrapMan you should do it again but with 8 "channels", using the 1x1 wedge block in an 8 sided star pattern. You could probably get a lot more interesting movement patterns as you could have up to 8 pins, and it would be a cool follow up working it into a spud gun or something (or maybe a walker with an interesting movement mechanism?)
I love these videos. i stopped watching for a while but these videos making cool irl machines have brought me back. i got an idea what about a ball bearing system?
well now scrapman's channel has become an educational one with a twist, he explains mechanisms in a game while others do it in a simulation, this one is way more fun :). keep giving your important and valuable knowledge for the greater good of humanity and science
Some time ago i needed to design a conveyor that would advance by a certain distance, then pause. A Geneva mechanism was one of the propositions, but i ended up using a Quick Return Mechanism (sometimes known as Whitworth Quick Return Mechanism or Shaper Mechanism). It consists of a rocking arm with a slot; a pin that's connected to a rotating wheel rides in that slot. With one rotation of the wheel the arm rocks to one side, then returns back at a faster speed. Should be a really simple build in SM, nudge nudge wink wink lol
@@johnderat2652 Not really. Due to the more realistic physics, the things I build, and I build really complex creations that go exactly to max complexity, tend to work perfectly (other than causing lag). Simple things like this would be easier in Trailmakers, especially since you can make circles
Very interesting. Was unaware of the history (or perhaps lack thereof) of this mechanism. I see a lot of suggestion of using this to power a car wheel, but I'm curious of the implication of powering a walker. Much like the Strandbeest, converting rotational movement into a walking motion. Could potentially even be survival viable as this could be powered by a controller. And now I think I have a project!
Scrapman Look up The M400 Sky-car i still remember reading a article in 2003ish Paul Moller Tried to make a real life VTOL I think you will like the idea and story Can be made in either Trailmakers or Scrap Mechanic
Okay now use this to make a RAIL LOCOMOTIVE or CAR. Actually that twitching motion breaking the mechanism could be resolved with a few well-placed wedges. Put the ratchets on a controlled switch that can rotate them 180 degrees.
2:29 My Kinematics of Machinery course in college used similar software called dynacam and linkages to help with visualizing mechanisms. I might just have to send you my old Kinematics textbook, you'd probably get a kick out of it
I'm actually pretty impressed by how you got this to work @scrapman! I would like to see you optimize this system and maybe turn it into a walking mechanism of some kind?
You could probably use the massive quarter circle pieces (the cylinder parts of what you use to make the balls) to create a curve large enough to mimic a concave version of it with wedges & pipes.
The comment section over here talking about guns and clock mechanisms, meanwhile I'm here like but can it work as a transmission system for a vehicle though? Or will the transfer mess it up? While typing this I also thought that it might need two of those ratcheting mechanisms to allow it to slip and keep momentum but then still apply torque, if anyone wants to try to build it. Thanks for trying and showing this one Scrapman. Really made me go "HMMMM!!!!!!" Also thanks anonymous clock maker for laying some pretty cool groundwork.
In theory you could build the driven wheel (red one) bigger, but keep the drive wheel (green one) the same size, and use wedge block for a forty five degree angle, you could have eight slots for the driven gear
I think an actual clock/clock-like mechanism would be cool to see in sm (maybe with an offset arm that reaches up with a suspension or piston piece than can go through the middle arm so they don't collide)
That last part with the pauses would be great for a metronome, in 4/4 time you could have it pause one or play a different noise via color sensor, and the speed of the engine will adjust bpm while the number of pins is the measure time
when i did my version of a Geneva Mechanism, i also made it spring locked but mine is smaller, the 2 parts are aligned, not diagonal like yours, and it can go both ways i also made one that move rotate one way because an arm push it on the forward movement but it bends on the way back like a ratchet
Helo scrapman I have an idea that I think is only doable in trailmakers A plane which moves left and right on its one wing to turn.Noted: the wing must stay stationary for the most part.
You should build a do nothing machine, you turn a bar in the middle and lots of little bars move back and forth, narrowly missing each other. It's a simple mechanism but very satisfying.
I think an interesting thing to try, although hard would be a horizontal helicopter, its blades spin like wheels on a car and their angle changes so it always produces upwards lift, then by changing the angles of the blades you can make it fly forwards or backwards and also add tank steering
This looks like some fantastic hip joints for a walker.....just change the position of the drive pin and you could have it start all feet on the ground but then take incremental steps.
10:47 I like you, because this right here, would have been enough for me, and I would have called it a day. P.s. I really like the direction, content has gone in.
You could also try to build a model of a single piston dual overhead cam engine to show mechanics like the opening and closing of valves with the camshaft in Scrap Mechanic.
Make a swashplate or cyclorotor with the wings mod, considering you made a got damn strandbeast, I think you could do it. I'll allow suspension glitches.
Multiplayer Monday idea: Make a car Using this as the only use of propulsion except that you can only se 2 prongs and have to find if double movement or consistent movement is better, electric engines only No thruster no glitches
