Scrapman, for future projects when you despair on a project while trying to build an angled / diagonally bar, you dont need to, you can just build an L piece instead, because scrap mechanic dosnt have any flex on parts (only the distance between the bearings is important, not how they are connected). This might help you when you build more complicated stuff on a 90° grid like in scrap mechanic

or you could add a third pair of legs not connected to the purple bar and have it connected to the main body by a bearing, like the old walker

One problem you will always face with quadruped walkers: they will tend to tip to one side on each step (at least when lifting two legs at a time). You can make it work with big flat feet, but it will still be a bit wobbly. Smooth walking like in animals or DARPA robots only works with closed-loop systems with lots of sensors and control algorithms.

Just a thought: For turning, you might want to not link the front and back legs - this should let you break the creation into two sections, front and back. These sections can be connected by a center hinge/pin, creating steering from the center.

Another idea: the wider the walker is, the more torque around the vertical axis is _created_ by tank-style turning. And the longer it is, the more torque is _needed_ - so the answer would be to build as wide and short as possible without compromising stability. Clearly, centipede-like machines would be extremely inefficient at turning and need articulating joints between sections badly.

@2001herne

2 жыл бұрын

@@achtsekundenfurz7876 Thats actually incredibly insightful - the tank steering only applies force in one direction, and on long creations the moment arm of the turning force is fairly short. On the other hand, the moment arm of the frictional force at the very front and rear of the creation is comparatively large. Thanks for the food for thought.

It's called a plantigrade walker because of the "foot and heel" of the walker is placed flat on the ground like a human or bear foot. While a digitigrade walker has the heel higher up making it look like a backwards knee. Edit: It might be possible to make a digitigrade walker in scrap mechanic using pistons but it will be much harder.

Oh man I love this. For some reason it makes me so giddy watching all these unusual real life mechanisms being rebuilt in a video game. It's fascinating and entertaining at the same time. It's also slightly educational as well.

Okay, you got to have this in Multiplayer Monday somehow. Maybe build a gigantic version, that's more tanky, and have tiny planes try and hit its weak-spots; all the while, one (or two, depending on the amount of players) defend the walker, with either turrets, or just them running around on its battlements. Definitely try making it look like a walking castle.

But it's a really elegant looking set of linkages, very organic motion. Might be a good follow up to this vid .

Dude please upload that to the workshop! It’s so satisfying!

It is really incredible good job

Is that a Chebyshev's Walker!?? I remember seeing the CGI footage of such machine in a museum when I was 10

Definately continue with this mechanisms in scrap mechanic series :DDD

I made something somewhat similar to this with two legs in scrap mechanic a couple years ago. I based it on a window climbing toy called the cimb@tron rex robot. you mention at 11:56 that it can't be connected into a single mechanism without glitches. I also thought it wasn't possible to connect the left and right legs together at first until I thought it through. you can connect one of the attachment points that went to the body to the other side through a hole with a pipe running through like a bike pedal, so long as you have more than one so the other(s) can still be connected to the body with bearings (this one having four such attachment points). of course, you wouldn't be able to steer anymore. mine didn't turn, I used it for automated farming in straight lines.

You are still a Technical Wizard my good Scapman

That is one of the sickest things I have seen. GG Scrapman

There's only one instance in which an engineer doesn't just do what you did and figure it out as they go and that instance is if they have done it before. You're honestly a really great engineer.

I reckon you can implement steering with some of the legs selectively shortening slightly with pistons

For some reason, once I read the wiki page, did a bit more research, and had a proper understanding of how the walking mechanism works, watching the walker work was 100 times more satisfying

This thing looks like a fun science experiment

If you separate the front legs from the rear legs, you can probably put articulated steering in between and it would work quite well. Or heck, just put 2 of these creations together with an articulated steering joint between them! I'd love to see it then! Plus, at 200% max speed :)

Yet another nice addition to your recent series, keep it up :D I do think you can improve this and implement some nicer turning if you separate the legs ^^

I really want to make an eight legged version where for the legs are offset by 90°. So while one pair is in the middle another pair is going down in another pair is going up making it even smoother. If we were to do that we could also add a joint in between the first two pairs and the second two pairs allowing it to steer like your other Walker did

I love multiped walkers -a childhood filled with Ghose in the Shell, Armored Core, and Chrome Hounds made it all but inevitable- so this was really cool to see. I had two ideas for turning. First, rather than changing the cycles, could you add pistons to the legs and slightly lengthen the ones on the outside of the turn (slightly angling the legs and feet on one side might also work)? It would only let you turn while moving, and the radius might not be the best, but I feel like it would also give you a more natural motion. Alternatively, since you've already built up the foot mechanism, could you replace most of the blocks with lower friction blocks, but have a few high friction blocks on pistons that can retract when that foot needs to pivot? On a different tangent, could you make this a 6-leg walker, with 3 feet on either side. -Don't judge me! I know it had a different mechanism, but I want my Spirit of Motherwill!- If you can't, I wonder how that would change the turning. Either way, I hope you do more with walkers and this style of more complex walker, in particular. I think a multi-player challenge involving walkers could be interesting, but failing that even building out a more robust and fancy version of this one would be cool to see. Edit: If you're interested in doing more walkers, there's an entire website dedicated to building them, with a bunch of relatively simple designs you can use. www.diywalkers.com

the demonstration walker car at the beginning, made me want to see a multiplayer episode with the theme of racing vehicles with offset wheels like that, maybe even evolution if plausible xD

Loved this. Maybe you could try a Geneva Mechanism next?

I had been playing in Scrap Mechanic some years ago... and I made a giant spider ( inspired by the movie Wild Wild West )... not realy as big as the one in the movie ( about 6 by 6 meters, 3 meters high ) ... but working. 4 legs at each side, each controlled by a bearing for forward-backward movement.. the even numbered ones go opposite the odd numbered ones... then in each leg, about 1/3 from the body down to the tip that touches the ground, there is a bearing for some up-down movement. all bearings on each side are connected to a controller to sequence the for-back and the up-down movenents, left and right were independent from eachother, so I had some control over stearing and direction.

I’m glad you building it for me and that I am not the one building it lol

Use multiple bearings for where the powered bits spin, so then you can have multiple input affect your speed/direction. You could then use a simple sensor-block turn thingy to reverse one side while continuing on the other, allowing for turning on a dime, and also allowing the normal wasd input

This is much smoother than an exact replica in trailmakers...

@Jakubboss99

- at higher speeds...

Seems like the legs are able to move on a pivot on top of the mechanism when the lambda reaches turning point. You could extend the wishbone bit a tad and weld the leg straight with diagonal blocks.

.... If you disconnect the front & back legs, and add some logic, you can get to one planted leg to pivot around, W the 3 other legs, and increase the turn rate that way. Turning in motion becomes a differential stride pattern in any legged walker unless you use body flex turning. Thinking about it, a logic controlled stride pattern W player body steering that shortens stride on the inner side by detecting W sensors may be the best result... Could also pattern for longer stride on the outer radius, button interrupted plant & pivot (1 fixed foot, 3 in motion) for tight pivots... Possibly multiple speeds? Pass it on to KaN?

That's so cool!

My favourite KZreadr.

I got two prototype/failed ideas for you (both would be better in trailmakers besides the carriers probably because build space is limited). The anitnov A-10 soviet glider tank, it would be cool to see this gilded and drive around. And the flying aircraft carriers USS Macon or Akron would love to see controls for the blimp and planes along with the very difficult to pull off landing the aircraft on it system (there are some tragic stories with both of them but interesting machines still)

3:16 I honestly didn't expect to see Thang featured here

you should have a race where each of you base your creation off of a historical machine. I think it would be really cool.

Hi scrapman, if you want to try some interesting air creations there is this concept called "the sky hook extraction method" it was one of those old war ideas.

You can make variable swing arm (blue wiggly bars) length/positioning for turning

My man you could just bend the body in the middle like in the front-loaders and do WASD steering no need for 4 buttons, but have to say the build is really impresive tbh and the fact that you managed to actually connect tank steering to it is even more impresive

Sooo... You had a good distance between bearings the first time - you want to measure between centres, not the length of the entire strut, which gives you an extra half a block hanging out each end. With the version you ended up with, A was 3 units, your "2.5A" leg pieces were 9 units, and the diagonal was about 9.22 units (and hinging 7 units away from the base bearing) If you'd stuck with the 5-long struts you started with, that would have been 4 units between centres (A), then you'd need 10 units between centres for the 2.5A lengths (or 11 units if you count both the pipes that have bearings), and thanks to Pythagoras, placing the diagonal arm's base bearing 8 units away (between centres - 9 counting both bearing blocks) would have the diagonal exactly 10 units between centres! I rebuilt it to your dimensions, and mine, to compare them, and yours still gets impressively close, but it appears to be slightly higher at one end of the step than the other, where as building it by between centres measurements has no discernible height difference along the entire length of the step.

i'm not sure if its just me but in the video he seemed to forget the .5 part of the 2.5 and was aiming for 2x the length.

I made one of those with WASD tank steering! Had to put in 2 extra pairs of legs so the sides didn't need to stay in sync, and spammed pistons everywhere so a bunch of stuff could phase through each other. Because of how many bearings and pistons it had, the game's sound broke and I was at 15 fps. Still have it saved

I have an Idea for turning. Cut the thing in half so you have the front legs and rear legs on independent plattforms. Then you can connect the 2 platforms via a bearing. Another Idea is to exchange the "wobbly" bar with pistons so the radius on one side gets smaller. That should result in higher frequent cycles on one side and force a turning (with enough friction)

You can make like a cilinder under the walker that extends to lift the walker and a mechanism that turns the cilinder clockwise and counter clockwise

Mecanum wheels would be a fun experiment.

For better stability, the rear legs should be timed as such so that they have a 3/4 delay (180 degrees offset would be a 1/2 delay), allowing for the craft to always have 3 points of contact at all times. The front legs should also be slightly closer to the center of the craft to help balance it between footsteps: an acute triangle is more stable than a right triangle in terms of maintaining equilibrium across the central axis, as it puts the legs closer to alignment with the center of mass. For steering, you can simply add a joint to the middle so that the front legs and rear legs are walking in different angles. Combining this with the added ability to lengthen or shorten the gait of each side pair of legs will act as a quadrupedal analog for a differential.

What I like to do is try and build what you build in scrap mechanic except I build in trailmakers. And this is gonna be a fun one

that was very interesting. try making a strandbeast

Adding an adjustable weight to the center of mass will allow you to turn it easier via leaning. Similar to how quadrapeds turn while running, minus the body turn.

Would it work if you put the steering in the ankles and had the two feet that are down twist so that when the next feet come down it's off from the original line and then repeat. Just wondering 🤔

You should make a walking fortress series with a giant plantigrade walker as the base

For walking mechanisms, check out some old school zoids. When they’re barebones without armor, you can see that they rely on similar concepts to this platigrade walker, but some of them had steering mechanisms built in, and more moving parts to make them look like real animals in motion.

to make any vehicle turn you can add a piston under neath and then lift the vehicle up with the piston and then on the bottom of the piston can be a cross shape stand that can turn left and right
