after seeing this, i'd definitely be interested in a truck and trailer creation, think 18 wheeler type, with a gearbox, trying to see how much weight it can pull up slopes, down slopes, across terrain, etc...
i think generally vehicles that get through ice typically generate friction by digging *into* the ice, something that you can't exactly do with soapy wet glass
Actually, snow tires create friction inside their rubber (by being squished when rolling), and this friction creates warmth. This warm rubber melts snow a little and the tire gets some grip.
@@fridaycaliforniaa236that’s not true at all, melting the snow would create water, which would cause the vehicle to lose traction. They actually operate by having a more open tread pattern which digs in and grips to the snow.
To be fair, frictional force is independent of surface area; F is just force (normal to the surface) times the friction coefficient. A flatter surface like the track offered could increase the normal force (although it’s likely lighter, and I think you’re right that it was a step back) so it’s not an entirely unreasonable move. If it were actually ice, the tracks would be able to dig into the surface and generate non-frictional force. Obviously though that couldn’t happen here so it was not as effective as even the wheels.
@@anuran_annagrip in tires is much more complex than normal force and friction coefficient. that's a simplified formula that doesn't account for the fact that the friction coefficient for rubber changes with normal force, rhat rubber deflects under force and isnt perfectly rigid, etc.

Hi, only a consideration. The slope that you measure isn't in % but in degrees. The 45 deg slope is a 100% slope because for every meter forward you make a meter in height, so the ratio of vertical/horizontal movement is 100%.
The part with you pounding the ground with your fist in rage like a cruel disappointed god, causing the vehicle to shatter apart, was low key terrifying
Could the fabric be absorbing the soapy water, causing the pads to press against the glass directly? The answer to walking on snow and ice is definitely spreading out your point of contact, but I really wonder how this would be different with true ice.
@@YagoKatzen That's not true. Ice is slippery even to dogs and cats, which don't exert nearly enough pressure to melt ice. The real reason has nothing to do with pressure and was only discovered relatively recently. Basically the top layer of water molecules don't form a neat lattice and only bond to a couple of their neighbors. This results in a liquid-like substance that is only a couple of molecules thick on the surface of the ice. Also abrasiveness and friction are two different things.
On the other hand, spikes work well to add grip on ice, but would have no chance here with glass. The simulated ice is not comparable, but both are a fun challenge
Nice video, as always! Now, having to drive over ice and snow for about four months a year, I can tell you of a few fallacies that people spread that will absolutely put you in more trouble than will solve: 1. Pedal to the metal. Spinning your wheels and putting as much power as possible into the wheels will only worsen the situation. By going into dynamic friction (skidding) instead of static friction, you lower the actual amount of friction between the wheels and the ground. Thus the best way to get traction is to get the wheels spinning as slow as possible with the least amount of torque to the wheels. This can be achieved by shifting up a gear or two and slowly but not completely releasing the clutch with the engine at idle. Yes this is hard on the engine and gears but will give the best result. (sorry automatic car users, that is one big plus on the manual transmission side) 2. Being stubborn. If you are skidding in place, you will only dig yourself deeper into the hole, literally. If you start skidding, stop trying to force it right away. Get out of the car and look at the terrain and environment to find possible ways to help yourself. Oftentimes going in reverse will help as there is more weight on the front wheels and they will tend to dig into the road when backing up rather than lift slightly when going forward. If you can get some movement but immediately after start skidding, trying rapidly switching between forward and reverse to "rock" the car back and forth, sometimes you will be able to get out this way. If the terrain has a slope, try going the same direction as the slope, this will help. Lastly, if you have a passenger, friend or someone that can help, get them pushing, the sole of their boots has almost if not more area of traction as two wheels of your car and even a few dozen kilos of human muscle pushing one way or another can change everything. 3. Ignoring tools. If you do have to drive in a country that has icing conditions, even on rare occasions, if is unwise to not carry the appropriate tools during that time of the year.Chains, nailed tires and the very simple traction aids (metal ones are MUCH better than plastic) as well as a short shovel (even a trench shovel) and a small bag of gravel or gravel/salt mix may make you car a few kilos heavier during winter, but two or three dollars more on your gasoline bill each month may save you hundreds in time lost, stress and towing. Finally if you try everything and are still stuck, it is by no mean shameful to admit defeat. Don't forget that many people die each year because of bad road conditions and if getting your car out of it's parking spot is already a chore, think about your own safety and the road ahead first. Missing one day of work because it would be dangerous to go is better than not making it at all. Now i'm not perfect by any means but i hope this might help a few people.
Something I'd like to add, but it's not for the noobs: sometimes it's better to pull the abs fuse. Generally not a good idea but in some conditions you can stop a lot better without abs than with it. A locked wheel in snow creates a lump of snow in front of the wheel, providing greater traction. Don't do this if you don't know what you're doing though, you might kill someone.
@@rh3ttjI figured that might be the case, but I always have used driving in icy conditions as an example of something that I have no idea about but it's common knowledge for a local. I use it when I think of a skill that I know that seems like everyone should know (like how to swim), it reminds me that there is lots I don't know just because I am not having to deal with it day to day
When dealing with slippery surface, lots of little contact patches are better than fewer larger patches. The larger fabric feet worked because fabric is woven and therefore not flat so it has loads of tiny high spots which greatly increase the effective surface area.
@@squidwardo7074 it also changes the friction coefficient between the tire and the underlying surface as long as it has higher friction towards the surface. And since the fabric will somewhat stick to the wet glass it gives better traction. Kind of like if your standing on a wet floor it's slippery but if you place a towel over it you won't slip
7:31 - It will not affect result of experiment, but the fan blades on right fan were installed in reverse. Just compare to left fan where it was done correct
Big Brain Walker: If I soak up all the soapy water with my front legs, my back legs can have all the traction they need by walking on a dry surface! Next step, suction cup feet to beat the 90 degree incline!
@@LordDragox412 i honestly thought thats where this video was going once the walker was introduced although the unholy fusion dance of the fan-walker was funny
Part of what makes tracks work on a slick surface has gotta be the weight, combined with the ability to bite into the surface. There’s just no way to bite into the glass.
I think this test might be flawed at few stages - when you put dry tires, you gain grip and once they soak in, they slip anyway, so there's a increased traction that shouldn't be part of the experiment.
With the little nubbins on the tracks, the actual surface area is smaller than for the 4x4 or the 8x8. The rubber is just too small to be pliable, and makes only a tiny little prick of contact. IMO, the track would work if you'd use something that's as wide as the track bit itself. And it would need to be a pliable rubber. IF you used the wheel (i'm assuming they're wheel weights) weights then i think you'd be allowed to get 3M red sticky tape, stick the faces of the track links and then use a acetone soaked wipe to wipe off the glue, thus leaving that sticky rubber middle core they use exposed and very sticky. Should work with that. If not, then ... it's probably just too slippy. As is, it doesn't similar snow, more like the glass like surface of an iced up road... and on those, even the best tires fail. You'd have to get into nail tires or chains to get traction, but you can't simulate that with this experiment, because there's nothing on the glass to bite into.
Actually, on ice you would have to decrease the area of the contacts between the "feet" and the ice. With more weight applied on a smaller surface (like the nails inside ice tires), you could theorically bite into the ice and have a very nice grip.

It's too often a misunderstanding that tracks inherently have increased traction vs wheels. An increased contact area doesn't actually increase friction - this video did a good job of demonstrating that. Tracks' biggest benefit (IMO) is that their increased contact area prevents them from sinking into loose substrates such as snow.
Really Nice Work!! You could try as a next upgrade to the legged one to put suction pads with pneumatics! synchronized when leg down to suck the ground and release when leg up.
...Or maybe try custom pointy soft cones. The pointy top facing downwards to the ground and soft like thick balloon type that keeps the shape (hollow silicone ones?). And not sealed so it may suck the ground on its own. I imagine that when the leg presses down the pointy nose will like to deform inwards trying to make a tiny vacum cavity.
That was cool as hell! I'm seriously impressed by your creativity and engineering. Those last few vehicles were otherworldly. And this just goes to show the importance of having the right tires/shoes. You can have all the torque, tires, and weight in the world; if your contact patch does not have sufficient grip, you will not go anywhere.
@Qpwrtm it does change thrust. From wikipedia, about contra-rotating blades: Contra-rotating propellers have been found to be between 6% and 16% more efficient than normal propellers.[4]
@Qpwrtm As the air is already rotating about the center of the first fan (like a screw), the second blade requires a higher wing angle to maintain an effective angle of attack and lift. However, high wing angles can reduce lift, as the propeller starts to line up with the direction of movement, and the component of lift parallel to the direction of movement reduces (the reason why propellers arent very efficient at high velocities. Contra-rotating propellers is a solution. A heavy solution, but one that wouldnt add any weight to his design, as he already had 2 independent propellers.
@@ytaltacc8008 The blades seemed to be roughly aligned between the two propellers. Would off-setting one of them by 30º or so impact the diminishing returns of the screw effect?
Superb video!! I have some suggestions to try 😉: - Adding fabric or soft rubber to caterpillar track - monster balloon tires where you can play with the tire pressure (less pressure = more surface) - making the vehicle lighter with helium balloons 🎈 - ways to more GRADUALLY increase the speed from standstill (find the point where you exceed the roll friction) - spikes - adding a horizontal part to the track where the vehicle can build up momentum
*@Brick Technology* 5:33 One of the problems is that the legs isn't "paired" correctly, you should offset them. Currently they are "paired": 4 & 2 (contact with surface) per cycle. it means it has great grip when 4 legs have contact, but slipps when 2 legs have contact. You DO want them to be paired: 3 & 3 (zig-zag), eg: right 1 & 3 + left 2 for one step, then Left 1 & 3 + Right 2, per cycle. (it looks like it changes "pairing" over time, that's problematic too)

Most certainly. Not the same test.
This. I think it’s the only reason why adding more tyres helped.

The moment the fan goes on with the epic music in the background xD glorious
i love how it went from driving on the slippery water to straight wipe it off with fabric
fun fact: most modern cars would fail this because they are too big to fit on the glass!
That’s way funier then it should be
3:28 Damn, no reason to obliterate you're creation like that😧
3:47
This reminded me of a snow chase scene from Taxi 3
Yes yes, I remember it
The ability to do 5his was my childhood fantasies. Fantastic video.
Great builds & vids! Static friction is greater than kinetic friction - better traction when tires are not skidding!
Diddy disliked this video
Wdym
Bruh lol
@@FormatsliDiddy want his shi slippery he don't want no friction
Didn't know I liked and commented on this lol
All slope climbers eventually become helicopters when optimised enough.
If you made the blades spin in opposite directions, maybe it would have generated enough lift to climb the ramp
That wouldn’t change the thrust
@Qpwrtm it does change thrust. From wikipedia, about contra-rotating blades: Contra-rotating propellers have been found to be between 6% and 16% more efficient than normal propellers.[4]
@Qpwrtm As the air is already rotating about the center of the first fan (like a screw), the second blade requires a higher wing angle to maintain an effective angle of attack and lift. However, high wing angles can reduce lift, as the propeller starts to line up with the direction of movement, and the component of lift parallel to the direction of movement reduces (the reason why propellers arent very efficient at high velocities. Contra-rotating propellers is a solution. A heavy solution, but one that wouldnt add any weight to his design, as he already had 2 independent propellers.
@@ytaltacc8008 The blades seemed to be roughly aligned between the two propellers. Would off-setting one of them by 30º or so impact the diminishing returns of the screw effect?
One of video in long time, which I've watched without fast forward. This guy is a genius
This is the video i enjoyed watching without loosing attention since very long. Definitely deserves a like😂.
4:30 .. fck it. Get that Tank
4:00 *intense gau-8 noises*
5:40 looks almost like the AT-TE walker from star wars the clone wars :D
It almost looks like a MG excelsus from metal gear rising:reveagence
All the stuff on Netflix, Hulu, etc... and yet this is infinitely more entertaining.
What does that tell you, Brick Technology?
The humour is fantastic 😀its awesome to watch
"one must imagine Sisyphus happy" wrote Albert Camus in 1942.
good way to clean your lego wheels
Yep
1:26 what's the physics here?
What do you mean?
Thanks for the best content ive seen in many years, faith in RUclips restored
Superb video!! I have some suggestions to try 😉:
- Adding fabric or soft rubber to caterpillar track
- monster balloon tires where you can play with the tire pressure (less pressure = more surface)
- making the vehicle lighter with helium balloons 🎈
- ways to more GRADUALLY increase the speed from standstill (find the point where you exceed the roll friction)
- spikes
- adding a horizontal part to the track where the vehicle can build up momentum

5:33 One of the problems is that the legs isn't "paired" correctly, you should offset them.
Currently they are "paired": 4 & 2 (contact with surface) per cycle. it means it has great grip when 4 legs have contact, but slipps when 2 legs have contact.
You DO want them to be paired: 3 & 3 (zig-zag), eg: right 1 & 3 + left 2 for one step, then Left 1 & 3 + Right 2, per cycle. (it looks like it changes "pairing" over time, that's problematic too)
1:41 "help"
One of the best videos i've seen on the last months
Impressive! Watching Lego conquer slippery slopes is fun! 🏔🔧
He turned a car into a cleaning machine
Its a slippery slope.
bad piggies island of dream IRL
When I was little I loved playing with LEGO, your videos are making me regain that passion 😂
LEGO... Still one of the best creative toy systems in history. Love your vodeos❤
Imagining a channel where subscribers connect authentically and interact as passionately as they do here.
6:21 _small enemy spider_ *BYEW BYEW B-B-B-B-B-B-B-B BYEW BYEW*
😂😂😂
2:34 starting to become a truck
U should continue with ur air engine videos
That last creation was worth all the checkmarks in the world
For the first time in awhile I’m asking myself “how did I get here?” And it’s a good feeling, reminds me of the good ol days on watching RUclips back in high school a decade ago
6:44 stepping machine is cheating, because it is cleaning soap and water
How is that cheating?
Soap and water is continually being added
5:12 METAL GEAR?!
Robotics
*insert metal gear rising- collective consciousness*
