This actually taught me a ton about vehicle suspension! Although, I'm curious, wouldn't it make sense to always have the differential locked?
"Locking" the differential is like turning it off temporarily. While It's needed to make turns in vehicles, it gets iffy in rough terrain, like this. There is also half lock diff which does a mix and is good all around but still might not give the power you need in rough terrain/the extra spin to get around tighter turns. I remember one really old video explaining the evolution of differentials, its probably not too hard to find and really interesting if you haven't seen it
The reason to turn it on (/not have it locked) is that when turning, the outer wheel travels further than the inner wheel, so has to turn faster, which can't happen when they're connected by the same axle, without slipping. When there's no drive to the wheels, you can put them on separate axles, which allows them to turn at different speeds. The differential is needed to provide drive to the two separate axles at different speeds.
@@bw1llisthis was also a big limiting factor when trains were invented, since the wheels had to be on the same axle. They fixed this by making the contact area have an angle, so that when the train goes through a curve the outer wheels get pushed out, sliding the contact point to the thicker part of the wheel, and thus covering more distance with the wheel per rotation compared to the other wheel
@@elmo_is_watching_ya5175Ive always found how train rails and train wheels were designed to be absolutely genius. I miss the days when engineering involced practical solutions instead of heavily relying on mechanical solutions. Thats not to say anything bad about having mechanical solutions lile a differential, which I know is needed for cars, but thats my point. The more advanced we get the less we're able to use simple solutions. I find beauty in a lot of the simple solutions we used to use but sadly they arent as applicable to our needs anymore
Dif lock made it harder to turn your car.. because when you turn, the inner wheel will rotate slower than the outer wheel.. Locked dif when turning resulting in 2 scenarios either the inner or outer wheel will dragged along..
If I saw the final product on a shelf in a shop as a lego set I would think it was one of the most mechanically interesting lego sets ever 🤩

I imagine the guy from the Lego commercial yelling "Heyyy!" Every time it gets stuck and has to be rebuilt.
0:47 crazy how counter intuitive it is... more weight, less sinking in😊
its because the front wheels where dead, so they got pushed in, if it was AWD at this point is should have been less of a problem
I know how it works, all i said was its counter intuitive
I assume when the weight is toward the front, the the rear wheels don't compact the sand at all, so when they run, the just throw loose sand instead of pushing off of it. With the weight over the rear tires instead, it must compact the sand together enough that it aggregates into a solid enough surface to get traction on.

Four wheel drive ftw! Although in this case he ended with a duce-and-a-half
@@KewneRain For Lego logistics, accept no substitutes!
Came here to say exactly this. This is one of the best example videos I've ever seen for explaining how 4wd and diff locks work. I'll probably use this as a resource to explain it to people.
Not only diffs locks, but also tires thread pattern - the "bigger" ballons, they are not sligtly bigger but have offroad pattern that works way better than on-road ones.
The biggest factor in sand driving is more tread contact. Hence why you always air down your tires as much as you can to increase the surface area. Many people will buy jeeps with large aggressive tires and will get outperformed by a standard jeep tire that has been aired down appropriately. This experiment takes airing down out of the equation
Kitties are always helpful. They inadvertently expose possibilities humans may never otherwise discover.
This video was such a joy to watch, especially when seeing the finished product! I loved seeing the problems overcome.
I am amazed not only by your ability to make unique vehicles but also how compact you are able to make them! Keep up the great work!
Hmm
Thanks, I don't have space for big vehicles :D
@@BrickTechnology what you could also do to have even more traction is flip those tractor tires around so the arrows are poiting back and it will have more traction
@@kollinspencer847 I’ve got a bunch of equipment IRL, the reason the tires are that way is to clear mud from the tread. If you put them on backwards you actually have less traction due to a build up of soil
@@phillipcurl true but they work better that way in sand for instance
This is a masterclass of mechanical engineering based on different challenges. A detailed video on how the last model iterations were made would be incredible to learn from. Even the basic RC steering model would suffice
If you asked the creater, they'd probably call it mechatronics. Bloody good veiwing either way

I find it amazing how as soon as you hit the 1kg point, suddenly complexity had to skyrocket to make sure it could keep functioning. Then that complexity added even more weight which meant even more complexity.
It's basically the square growth law for lego mechanics
Or he couldve went with simple tank tracks or wider and wider wheels but thats not entertaining
Yh because tanks are meant to drive through anything he's building a car in the video
I have to wonder if things would go better if he'd just ditch the differentials. Always ends up having to lock them to get over tough spots anyway, so leave it that way permanently. Would cut down on a bunch of weight and complexity.
@@adriansue8955yes, but going through bends becomes really hard if you can't turn your wheels at different speeds, especially in sharp bends.

Those gear shifting rings were a HUGE advancement for the TECHNIC series. Absolutely incredible that LEGO continues to make such simple but revolutionary pieces for modern builds.

It's funny how he over engineers it too. Solid axle? No thanks, let's make a differential with locking diff and lock it instead lol
@@zackj997 I hope you are joking. It's best to lock and unlock your diff on the go and it also serves to show the difference between both
@@JustRememberWhoYoureWorkingFor Yes it made more sense as the video went on. Early on it was only RWD going straight in sand which LSD only has disadvantages in.
It is an impressive demonstration of mechanical linkage and packaging/arrangement. However I was struck by how this was NOT functioning well. In the final sequence the video cut just at a clicking noise and it was clear the limits of the plastic parts had been found. Surprised that doesn't cause problems more often actually.
1:03 was waiting for a "clean sand" prompt to pop up on screen lol
The voice coming in legit startled me, like woah there's a person there after all!
5:42 tractor tires with V shaped grooves are actually designed to dig into, and throw mud outwards as they rotate. Ideally you would turn them around backwards when driving on sand. This is why you sometimes see one or two pair of wheels being flipped on tractors that are being used on beaches etc. It is the same for winter tires also, those are usually designed the same way. In winter tires you ideally want a small, sharp tire and somewhat heavy weight, to penetrate ice and snow. On sand on the other hand, you want as wide tires as possible and as little weight as possible (while still having enough to maintain some ground pressure).
Thanks this will be useful in snow runner and or farming simulator 22.
I don’t think these are deep enough for it to make much of a difference
@@stephonragland1654 Tire setup doesn't matter all that much in FS22 unless you use "REA Wheels" mod that adds proper traction managment but that has a few hiccups when it comes to modded. Me, personally, I prefer to run single wide BKT or Michellin tires with weights as it gives me a tighter turning circle and I can park tractors and equipment in tighter spots than I could with doubles.
@@racer927 right thanks
One of the reasons I love this channel so much is you end up showing off the reasons why things are designed the way they are, and that's super interesting to me.

That's actually a very good way to test and make observation of real cars' interaction with sand. I also REALLY love the evolution and expansion of that vehicle, from a simple pair of technic bricks with wheels and an engine to a seriously badass looking truck with amortization, gearboxes and all.
What does amortization mean in this context? Only heard the term when trying to calculate loans/interest.
@@streetsurfer420amortisation is suspension
Everything started as a prototype And scale models usually come first
@@streetsurfer420 amortization or a suspension is a part of automobile that dampens the effect of road surface to the body of a vehicle and helps to ride smooth and to keep the body straight up
For real cars, maintaining momentum is the best way to not getting stuck in deep sand. This is a really good example of how important lockers are in 4wd, both lego and real
I love how the RC evolved from a tiny little 4 wheeler to a full blown 6 wheel truck. The stop motion redesigns were incredible. Engineering masterclass. I wonder 2 things. First, if it would be possible to connect the steering mechanism to the drive wheel, so it can accurately rotate. Second, if tank tracks would work better in the sand.
Oh tank tracks would most certainly be 10x more effective in almost any terrain. More surface area to grab onto terrain.
@@jaredchampagne2752 they can also very effectively get clogged if designed improperly.

Litter box actually
you might find it works better if the tread on those last tyres are reversed. in the current orientation they start digging when they lose traction, which is good when you have hardpack lower down, but sand is soft all the way down lol if they are flipped they will scoop sand underneath the tyres instead and raise the wheels out of the ground :D

This really shows why independent suspension and knobby tires were invented. The last tires had more of a knobby profile, not just more square. I ride dirt bikes in Michigan which is mostly sand and my MX14 sand tire is skinner and more round than other dirt bike tires but with a more aggressive tread pattern, in the sand, you need to dig in and grab as much soil as possible to move forward. You almost had independent suspension by the end which would've also helped with the uneven terrain. Things you may already know, just my 2 cents.
When driving on the sand or in the mud, it is important to keep the speed and momentum.
Just imagine if this guy could build full sized vehicles like he does these.
Judging by his work I wouldn't doubt he could
