From 4 wheels to 8 wheels to tracks to a spider robot and finally to a literal abomination, that’s just how engineering is basically. Great video.

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...

Those studs on the tracks ensure there's even less of a contact patch than even 4 tires.

fan walker has to be the most diabolical creation ive ever seen... but I love it

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

The desk slam to deconstruction editing was outstanding. Really clever production and great seeing the build context and you go through these iterations. Always really impressed with how you record all of this.

When the spider is OP and just doing 180 on the way down. *chefs kiss* lol

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%.

Wake up honey, brick technology just uploaded a new video

Love how we ended up building an AT-TE part way through

I love the repeating structure of these videos (problem > failure > new idea > success > new problem). Ingenious videos. Great work!

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.

That ending was actually hilarious. I do wonder however how much soapy water the fabric absorbed and if that made it easier for it.

I am a huge fan of the transition from 8 wheeler to tracks, great little collection of cuts

I gotta say, this video was infinitely more entertaining and educational than i first thought it would be.

I think this is a best rep helpful for students who learns Automobile or engineering. Myself not interested in this field because I couldn't comprehend the practicalty in theory. But watching this helps me to figure out how amazing it is. Kudos

The subtle humor and the little details are insanely good, love the editing. Awesome builds!

You could have added fabric to the tires aswell. It's a common thing here on in winter if you het stick

Oh my god, I could listen to these clicks all day over the gun sounds they make us listen to.

I like how the more difficult the terrain becomes to traverse, the more animal-like (or atleast adaptations of methods that animals use for motion) the features of the machine becomes.

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.

All slope climbers eventually become helicopters when optimised enough.

As someone who is always amazed by physics, mechanics and such, this is quite satisfying to watch!

That crawling thing is super cool 👍

This level of construction genius is insane! I love it!

Seriously, the sound of "one must imagine Sisyphus happy" keeps vibrated my mind while watching this lol

Love how it starts as a normal, every day driving experience and evolves to what can I build so it clears this challenge lol

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.

Me on my way into my room after a whole day of social interaction 5:53

I love how you make the Lego vehicle become more and more stronger and advanced to overcome the increaseable steep slope.

I absolutely love this! Such a masterpiece! That huge creation at the end!! I live seeing the evolution from vehicle to vehicle ❤

0:02 i like how it actually behaves like an open diff, one wheel peel n' all

The sound effects are subtle but very awesome (and the builds are cool as always). Keep up the good work!

at the end i was expecting i big helicopter rotor on top and a small propeller on the behind to push forwards when the vehicle is off the ground. did not disappoint though! had a good laugh

Loved the video, amazing ideas and production! In case you're looking for more ideas, I'd be curious how a FWD car would compare to a RWD or 4WD one, and if very very slim LEGO wheels (motorcycle?) would compare to the wide ones you used. As for the monster walker in the end: could one make an system that activly "engages" suction cups in the feet when they're put down in front and disengages them when they're in the back? I could think of something, but I'm not sure if I could do it out of LEGO parts alone.

Brilliant! Would love a part 2 with 60+ slopes... maybe suction cups? 😀

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.

Your creative problem solving abilities are off the charts! This is also all I watch while hopped on the giggle bush now lol 😵‍💫

Когда у конструкции ещё были колеса, то можно было на задние надеть гусеницы, чтобы получить большую площадь сцепления. Добавлено- Шагоход выглядит впечатляюще. Отличное решеник

4:12 this moment really made me think of a Gaston Lagaffe gag with his car XD

when the vehicle slowly slid backwards in defeat, I felt that

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.

I love how much you go back to the drawing board and aren't afraid to start over.

It's great that you show your creativity every time with a logical idea, man.

4:59 Illegal building techniques!

honestly I didn’t even read the title I just saw that it was a brick technology video and clicked on it

OOh man, the ending was epic! Thanks!

Not what I expected to see. Nice builds. Creative. Very entertaining.

Didn't think the editing could get any better, but this one's amazing! Loved the little breakaway segments. :)

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.

The moment the fan goes on with the epic music in the background xD glorious

Amazing video! You’re very creative with Lego and also amazing at engineering, drive mechanisms and such.. Fabric works well on wet/slippy surfaces.. already used on snow socks for cars.. also rock climbers back in the 50s sometimes used to ditch their boots and climb in socks for steep technical climbing if the rock was wet. I wonder if the wheels or tracks would have worked better with fabric covering them?

3:47 This reminded me of a snow chase scene from Taxi 3

3:28 Damn, no reason to obliterate you're creation like that😧

4:30 .. fck it. Get that Tank

This time on Top Gear: Hammond uninvents the wheel

Friend: "What do you wanna do now?" This guy: "Well..."

These videos make me think like a kid again, like how would i make it work. I love thr process

I love the last one it's absolutely crazy. What I would do is put propellers blowing air upwards on the 8x8 with the wide wheels. That way you would significantly increase friction and climb up the slippery hill

*@Brick Technology* 5:20 What about suction-cup feets? :D

Man, watching these lego videos is really addictive, I just watch one and if I’m not careful it’s a… well then

dude, this is amazing and by the looks of things a master builder

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.

Always a good day when Brick Technology uploads🥰

this is my second fave video ever!!!!!!!!! The first is sinking lego ships!!!!!!!!!!!

his videos demonstrate engineering very well. to starting off wtih a design and making the objective harder and imporoving that design is very cool.

It’s cool to see the natural progression of the treads and their weaknesses. It kinda makes you think about how much the militaries wasted on testing tanks in WW2 when they could’ve just used legos 😂

If you made the blades spin in opposite directions, maybe it would have generated enough lift to climb the ramp

One of video in long time, which I've watched without fast forward. This guy is a genius

That crawling thing is really cool 👍 That ending was actually hilarious. i also love lego.... you are the best

7:55 bro NASA is finding you

This is one of my favorites yet. I will say though that adding weight gets you rapidly diminishing results as the slope increases as that weight ends up actively dragging you down instead of helping you get grip.

Amazing video just as always man! Keep up the great work!

This was so much flipping fun to watch. Thankyou!

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.

Really cool idea and execution

The fact that he knew how to com up with all of the designs is incredible. Would not of expected from 2wd to the end, this was awesome 👍

Funny how the crawler works much better when both sides are in sync. Cool video!

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.

U should continue with ur air engine videos

the robot with socks is adorable i hope his leg healed up nicely

When I was little I loved playing with LEGO, your videos are making me regain that passion 😂

U really chose the least picked title 😂 Respect

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.

props to this 🙌

😂 great work man, good content for late night watching, keep it up!

"one must imagine Sisyphus happy" wrote Albert Camus in 1942.

bad piggies island of dream IRL

Hi, what parts are used in the video (ex. PF, Technics, MS, ...)? I'm interested to get similar parts to do MOC engineering projects. Thanks.

I would have loved to see the 8 legged beast have suction cups for feet lol

60° - это сильно. Нужен, явно, не стандартный подход к решению такой задачи. Но, как мне кажется, резиновые колеса - лучший вариант. Много маленьких резиновых колёс.

Its a slippery slope.

This is just so amazing! Great stuff 🤘

This is so cool! Keep this up brother, enjoyed every second of this

Nice vid

*@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)

This was in my recommended, enjoyed this fully. Id like to see this but on a rough surface. I'd suggest sand a piece of wood with coarsest sand paper you can find. Or glue dirt with epoxy onto a board.

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 KZfaq back in high school a decade ago
