@@BrickExperimentChannel Would work just fine with a pulled rope one. We used to do this experiment in school. Fishing line between the desks, two pulley type rollers for wheels and a gyroscope, locked on one axis. Pull the rope, and give it a shove. It wouldn't climb the desks, but it would cross the meter span between them just fine. I'd say the whole thing was about half a kilo in weight, with the pulleys about... 3 cm diameter and the gyroscope a large brass wheel of 15 ish cm. The bottom part of the gyroscope cage was just about a cm above the fishing line (if you'd describe a sphere with the diameter of the wheel).
@aserta That's interesting. Apparently gyroscopes are more powerful than I though. Here, I found a nice video example. th-cam.com/video/XdVXrno-3B4/w-d-xo.html
that moment had me stumped. the iteration of the vehicle prior to adding the string guide powered almost all the way there defiantly, really curious if it could have dismounted the string successfully had it made it.
They're only this effective because the black bricks have a core made of steel. If they were just regular plastic bricks, even if solid, they couldn't counter the weight of the battery box. And sadly Lego doesn't produce this brick anymore and hasn't for decades :(
@@PhoenixClank You can do this with normal bricks, you just need longer arms. Also, you can buy repros for the black bricks. These days repros are so good and cheap that it's not worth buying LEGO anymore.
When I have seen the hanging weights I thought for a sec "sure, it may help to cross the bridge, but that way the vehicle will not be universal anymore - I mean, how it will ride on flat surface with these weights". But then I saw you made them folding, which is brilliant)
With the last design, immediately made me think about how tightrope walkers do it, using extra mass to push their centre of mass below the rope. Clever :)
Tight rope walkers have another element that this machine doesn't have. They move the weights left and right, backwards and forwards to balance on the rope. If you'd put a camera down the line looking at the front of the tight rope walker, you'd see the individual move ever so slightly up and down, left and right respective to you while the weights are relatively static in plane. It's a ... different balance act.
You know what i would love from some of these every once in a while. After you complete the last go back and see how many previous versions the final one can. Like i think this is one of the few that can do all of the previous as well as the final! That would be fun
I’ve seen videos before where people program regular NXT or EV three Along with some custom parts to work with a gyroscopic system. That could be a cool way to do this as well
Why not use a gyroscope? Then you can even be very top-heavy and it'll still balance. This way even perturbations like gusty wind couldn't make it fall easily.
@elif6908 I mean it depends on what you think is small enough. It can be bigger than the car, as long as it's placed above it. The height of the center of gravity doesn't matter that much as soon as it's spun up
would a long vehicle with a weight that can be moved to either end work too? So you can just dangle the front end to the other side and move the weight over to the front and drive?
Yes, I think so. It wouldn't even need moving weights. Just a vehicle longer than the bridge would be enough, since there are always 2 wheels off bridge to balance it.
I'm not quite satisfied with the final design. Having to lower/raise the weight feels like a hack. Self balancing solutions (using gyros for example) would be fun to see.
It's as much of a hack as wheel rotation is to forward motion Sure it's done manually for the video, but could easily be automated with a couple sensors.
i like how the last one unjanks itself by swinging the weights.
Could a really fast flywheel work as well?
I think so. But only if the bridge is short enough and the vehicle fast enough.
Or gyroscope
And what do you think about fly wheel is?

you pulled out the string and i genuinely thought you were joking, but there it goes, crossing halfway without modification
that moment had me stumped. the iteration of the vehicle prior to adding the string guide powered almost all the way there defiantly, really curious if it could have dismounted the string successfully had it made it.
I love how each vehicle has personality
2:56 do it, do it, do it, do it, do it, do it, do it, do it, do it, do it, do it, do it, do it, do it, do it, do it...
YEAH!!!
yes
so satisfying!
That arm swinging technique at the end was siick
The hanging weights kinda blew me away with how effective they were! Awesome video, per usual 🙌🔥🔥

Calls piece of string a bridge - now THATS undeterred engineer :D
I love how the solutions always gradually get wackier on this channel

I love how you take a childhood love and turn it into real physics concepts.
Wake up brick experiment channel uploaded
I don't know why, but the last one swinging the arms is so funny to me.
Awesome as always!

The sterility of the studio is incredible. White tables, white shelves. Not a spot anywhere.
a couple of blemishes can be spotted on the wall when the tables are pulled apart 2:18
oh and 2 random holes in the plinth at the bottom that are not on the same height for some reason!
I know it works still work but it would be cool to see the final design traverse all the previous challenges too
Right at the start I was hoping this was going to be about weights and balance. I was not disappointed, especially on the final move.
This was an emotional rollercoaster.
This is totally delightful!
These videos have come to be top of the list when I see one has been posted. I genuinely stop what I’m doing and watch.
These are the only TH-cam videos I let me kids watch. Great job.
This is like the balance bike at the California Science museum
What a twist ending!
The last one is like "WE! ARE! GOING! TO! CROSS! THIS! Ah, there we go."
I was kinda hoping to see a double flywheel solution, like in that self-balancing monorail
2:29 I'm not even at the final thing yet and I'm impressed as hell that it got that far.
This changes from car to bike real quick
I was hoping to see a gyroscope involved. Maybe try testing if it can cross a narrow bridge that's also curved?
I’ve seen videos before where people program regular NXT or EV three Along with some custom parts to work with a gyroscopic system.
That could be a cool way to do this as well
Damn, and here I was, hoping that you would use a gyroscope somehow. Still turned out fantastic, though, as ever.
THE OG IS BACK!!!!!!!!!!!!!!!!!!!!!!!!!
Also technically accelerating the car fast enough so it slides the gap is also a solution, right?
Best video I watched in a week (and I watch a LOT of videos). Thank you for the laughs and the thought and the education!
There is a device at the Saga Prefectural Space Science Museum in Japan that allows you to run a bicycle on a rope using the same principle.
That's beautiful. I found a picture of it.

Is making a Lego gyroscope even possible? With this design everything is Lego can one make a gyroscope small enough for this car from Lego?
@elif6908 I mean it depends on what you think is small enough. It can be bigger than the car, as long as it's placed above it. The height of the center of gravity doesn't matter that much as soon as it's spun up
I wanted a gyroscope car 😭
Support wheels are so cute 🥹 2:54 😂😂😂
That string bridge is super ridiculous you're gonna make me laugh
Cool idea... Now make a corner on narrow bridge. :D
I would put at least a blanket under the trench so that the Lego lasts longer.
BABE WAKE UP BRICK EXPERIMENT CHANNEL UPLOADED!
The marvel of flight
IVE BEEN WATCHING YOU SINCE I WAS 9
Me when he adds hanging weights: "Yeah, what's that gonna d- WHAT MAGIC IS THIS?"
My goodness I just love these videos!
2:05 courier with suitcases :)
I would love to know the mechanics of the hanging weights and why the longer arms worked.
HE'S BACK
Just wonderful ❤
Awww I was hoping to see some sort of gyroscope. Guess it just goes to show simpler is usually better though.
2:25 The most tragic moment in engineering history. He almost made it...
would a long vehicle with a weight that can be moved to either end work too?

I really was expecting a lego gyroscope
Science hell yeah
Engineering *
No new laws of science were found, nor known laws proven, during the making of this video.
Hence, engineering.
Motorcycle but OK, nice video 👍🏻
when the car crossed that pole i thought
“ok but there's no way it can cross anything narrower right”
and then it crossed something narrower
The first thing that came to my head with Middle wheel car was AKIRA BIKE
i love lego
Ich freue mich auf neue Videos, ich wünsche euch alles Gute! Lasst euch nicht zu sehr stressen!
2:12 ☠️ leak footage of fast and furious 9
Today is a good day because BEC posted
What about sewing thread or a much thinner piece of rigid material?
I was really hoping for a gyroscope!
2:28 that launch made me laugh
Me too xD
i love the one that takes his little briefcases to work
Holy shididilddlesls its that guy again.
Most favorite TH-camr yet ngl.
And the cable is not charging your phone
I'd like to see this but with a left, then right turn so the vehicle is forced to be fully functional
This is the end
У вас не бывает ничего невозможного :)
Haven’t seen this guy in a while glad to see him
Huh, pretty clever.
So freaking cool
😂👍
what if there would be a motor powered spinning wheel on top of this vehicle like an OG gyroscope, think it would help with the balance ?
we could travel to mars and back in 5 minutes by now if this guy worked in nasa
Now without the string
*how*
BABE WAKE UP
BRICK EXPERIMENT CHANNEL JUST DROPPED A NEW VID!
Legentary! as usual...
MAKE A TRACKMANIA CAR AND TRACKS!!!
Batmobile goes shopping
Legend Is Back!! 💥💥
I hoped he would use some form of gyroscope
This channel is epic
Idk you ever tried increasing any diameters?
That was awesome!
this is basically beseige but with lego.
the real physics
This is my favorite channel.
Thanks for the creativity and solid thought you put into these builds
Хе хе 😎
your designs are not backwards compatible.
Increase Wheel Diameter
👍
Bravo!

how would a greek dish help with engineering? unless ur feeding the engineer with it lol
i agree. wouldn't it be better to just improve tire grip?
Damn dude.. 5th?..
