- Today we're back in Scrap Mechanic with some simple bipedal walkers! I've never built a bipedal walker before using a four-bar mechanism so I decided to give it a try and experiment with some of the different four-bar systems we can use!

What else should we build in Scrap Mechanic?
you should make a car that can climb above rocks or trees and just destroys it from the top to the bottom love your content
Transformer
A full working AT-TE? ^^
The Boston Dynamics robot dog?
A car assembly plant. Like the one you used to work out. Could be done via glitch welders from the modpack.
honestly a full engineering college course based in scrap mechanic woul be pretty awesome
In my free time I would definitely take.
"Okay listen up, see this driver seat? STOP USING THEM, Use toilets instead, they are way more viable"
*Disclaimer: Toilets may gain sentience and heads, in that case flush them immediately and dispose of them.
I agree %100. my main logic and physics baised building games has always been Little big planet 2 and 3 and i've made some stuff with suprisingly complex logic but i've not delved into some stuff with walkers being one of said stuff much because i've not thought of any good leg movement mechanisms such as this so i've found this video very informative and i'm going to transfer this into one of my inventions sooner or later, i think it will be exiting. Also i recon this and other engineering(I think there's a better word but I can't think of it right now) vids should transfer over to other logic and physics based game platforms so i think their may be a fair amount of people interested more videos like this.
Scrap mechanic is cool but also physics can be extremely limited and broken
you are a genius
kAN in livestream with 2F and Ronan: "I wasn't a 'popular kid' in highschool, I was too nerdy."
Also kAN: (posts a 30min video on mechanical kinematics in Scrap Mechanic)
Checks out, and I enjoyed it!
Kan you should try to build that were the red bar is replaced with a piston and the pivot point for the red bar connected to two pistons (vertical and horizontal) so you can give it a variable gait.
We didn't know when we got up this morning that we would be taking a kinematics course taught by kAN, yet here we are enjoying every second of it.
I would love to watch you build a very functional vanilla walker
It's more fun to build your own
@@sargeonfire8005
Yeah but I'm not an engineer, he is 😋
Thank you for the lesson and your enthusiasm! Cool stuff. Enjoyed this and your last Scrap Mechanic rail gun video! Like the more in-depth walthrough and process
I love how kan thinks about how it should work and i just slap stuff together and test it over and over
not sure how many people come here to learn about kinematics, i find it fun to try and get my head around, plenty more for me to go and learn.
I absolutely love these videos! I've always loved kinematics and seeing you build these types of creations is very satisfying!
i absolutely love these videos, they’re acc so interesting
Loved the mathematical breakdowns. Please do more of them!!!
I am definitely going to try to replicate this in trailmakers
that last example that you made has a very robotic movement, while the others felt more natural and fluid
The fact that you made all of the example walls/legs! Amazing demonstration
This and the railgun video are great, liking that format of video.
(Just for "preface", some heads up that English isn't my primary language. Feel free, and appreciated for it, to correct any mistakes.)
I am not particularly educated in neither mathematics nor mechanics - I don't even have this program - but incurable curiosity in how all things work has made me look closer at a lot of things in life.
This is one of the best "ad's" I've ever seen for why and how understanding mechanics and trigonometry can be both fun and interesting. While I suspect few are looking at this and immediatly find a direct use for it in real life, I think there are lots of details in all of this that IS part of every day life.
It (obviously) touches on how complicated movement and balance is using legs. You can simplify the mechanism, but then you are compromising on one or more qualities. Even considering the limitations in what the programs allows you to build, I think you put on display some very real challenges to solve and what you loose in a compromise.
You also show how the parallel bars created a very stiff arm. It reminded me of how arms on assembly-robots and how the wheeldriving pistons on locomotives work.
Actually going into the math' of it all might be better to put in a separate video, both for those who don't want to dig into that at all, as well as for those who want to look this through multiple times BEFORE moving on to the deeper why:s and how:s.
Cool and interesting video!
I would like to see how to understand the math' behind it, putting the numbers next to the motion, and to see how changing the numbers affects the motion, just to get that connection between the math' and the motion it creates.
Now I need to make a four legged mech thingy using this.
As a math nerd of the non engineering variety, please share the math! I'd love to see it.
Looks like a backwards at-at, was waiting for what it looked like in reverse and whether it walks like one that way.
Loved this video man. More of this kind of content please.
Now I'm curious if that works in other games - Stormworks and From the Depth will get fired up again for this.
Edit: Doesn't work in Stormworks nor in FtD :/
From my (limited) knowledge of FTD I don’t think that there are the free spinning pivots that are required to make this work
@@johnmielke5840 There are, but the connection system doesn't support it
That was amazing. Good job, kAN. Now the really important question that is on everyone's mind: Can a walker ride a bicycle?
That's not possible without mods
@@sargeonfire8005 That's exactly what Edison said to Tesla. I think it might be possible. You just have to build some kind of treadle mechanism instead of a chain. The walker would also have to be "clipped in" (i.e. welded to the peddles) in order to avoid collision lag.
This is my fav kind of content
On the example where you say the red bar is flat and not moving, at 11:00, I would have just said: "The pivot point on the blue and red bar, and yellow bar, are aligned at this moment, sharing the same virtual joint." Or something to that effect. The only reason the red bar moves is because the blue bar lacks the range of motion to perfectly pivot there. If it could, the red bar would simply drop below the yellow and blue bar, reversing the system from gravity.
Or something to that effect. Neat demonstrations, however.
i miss the kAN streams from ages ago, building things live. fun ol' days! more tutorials like this would be cool though
yay new walker🥳
Considering the fact that it's about 3 in the morning as I'm watching this, I'm surprised that I understood your breakdown of the mechanics behind the 4-bar linkage as well as I did.
Maybe a big 4 or 6 legged walker? Or even 8 legged on, like a spider walker, because that would necessarily be of a different variety of linkage
I built an 8 legged walker with double bearings all around based off a walker SM did about a year ago. However it's in survival so I can't share on the workshop :(
Looks like a very strange horse...
Wonder what will happen if u make the dark blue member longer than the light blue
“It’s really simple” he says, Kan doesn’t understand some of our smooth brains
I think the center of mass on the walker needs to be lower to account for the longer stride and the black bearing needs to be higher so the foot tilts more forward so the heel doesn't drag. A low cockpit that has the legs attached above it would produce a long stride with low center of gravity. Low friction blocks on the heel might be good too so the drage doesn't affect it.
how about a quadrupedal system with this leg setup?
oh that's neat!
"Guess and check" is more fun!
Dammit. I want my PC back up and running. I've missed building and testing things in this game... These look cool to play with.
please reach out to try make a video with Reid Captain with this sort of mechanical stuff! you two would have so much fun in this game with your combined knowledge of the game and kinematics.
I just got into a warehouse without a key, I think the Devs need to rework the game a little
I was watching another kAN video when this came out... Also whens the next factorio video come out? I MUST KNOW kAN! I MUST KNOW!
This is dope. What if you make it so the toes of the walker has some flex so it rolls more then drag on the ground almost like a half tire but it straightens out when it makes contact with the ground…. I know it might not be possible because it’s scrap mechanic and I don’t play it I just have watched it so that’s another thing but much love kan keep the content coming
Love it
Very nice HowTo video!
"Because we made the member longer, we have a longer stroke" :kAN, 2023

Call needs to be a professor in geometry
Thanks, professor Kan
This is random but I made a 6 logic gate sequencer(kans is 12) so mine has less delay
I would like to see one with some hip motion added
Bipedal walker racing for Multi-player Monday?!?!
Is that mechanism can work with tank steering in scrap mechanic ?
Good afternoon! Great time to upload
Wouldn't you want to place the suspension on kne of the vertical bars? I think that would be closer to the way the calf works in keeping the foot level as jt gets closer to the ground
Time to build an At-At using this mechanism
Would this work in Survival? What with how wobbly bearings seem to be in survival.
How hard would it be to add another joint before the foot that brings the foot down earlier, lifts it up a little during the midpoint of the step, and pushes it back down before it leaves the ground so that the arc while the foot is in contact with the ground would be more linear?
Please build a piston powered train
I think your walker needs broader hips.
we need build together live streams
I'm going into highschool and learning this
cmon kAN, as an engineer you should know the drive is always known as a crank.
How much torque does a suspension glitch have? 😂
when kan says simple mechanism my brain stops thinking
kAN, wait. what did you do so that when you stop the legs legs do not go back?
Build the Boston Dynamics robot dog or challenge the others to do it
Is it just me or are all the walkers backwards to the examples.
you smart
the missing link between infantry and artillery…
a metal gear
He says parallel but I think he means perpendicular
17:12 Canada moment
My brain hurts
I waited a year to say this. Eat the freaking corn tina
it has a duck waddle
red and orange bar are always perpendicular to each other not parallel.
??? I'm not sure you understand what the word "perpendicular" means.
@bluefireanimations3712 they sure as hell aren't parallel....
Your joking right? Hard to tell online. The blue bars are parallel.
@@nikkiofthevalley I do know what perpendicular means, perhaps you should go back to elementary school to learn what perpendicular means.
@@raptorz1950 Go look at the video again. They aren't 90° to one another, they're aligned. That means they're parallel. If they were 90° to one another, _then_ they'd be perpendicular, but they aren't. Are we talking about the same part of the video? I'm not sure why this is confusing. I'm talking about the second mechanism.
@@nikkiofthevalley read my comment again I am talking about red and orange bar that kan told was parallel but they are clearly perpendicular.
Here before viral
Hello
