*Hi viewers, appreciate your feedback. Sadly I can not make instructions as this model is taken apart for other stuff.* I do read every comment, I am blown away by your reactions. Thanks a lot! I also appreciate your constructive feedback, use it to improve my videos and models.
@@osmacar5331 you know that this thing is made out of plastic and a bit of rubber and not (at least I guess so) designed by multiple people who are getting paid pretty well for designing it. Be a bit nicer to the builder, a 60° slope is phenomenal for a toy.
Incredible work, really well done! maybe take off the cabin and lower the center gravity a bit more, might give you a degree or 2 extra? maybe you can try to beat my recent speed record? i need competition!
No, taking the cabin off didn't deliver any advantage in degrees, because the cabin was very light. I tested for this, I would have shown it in the video if it really could do more...
896gerard Adding as much weight as possible to increase traction (as opposed to grip) may allow you to increase the angle as your limiting factor appears to be slipping as opposed to the entire vehicle flipping. There is a Lego part which is compact and contains lead as a weight for the earlier Lego technic kits, this would make it easy to keep the C.O.G. really low.
Nice that's cool the way it clime the ramp at steeper angle show the power that can be achieve when building with Lego 'cool upgrade I watch this before it is amazing to run across terrain out side very cool
Hello ! The first thing I want to say is WoW ! What an amazing lego creation. I also have a question do you have some picture of this creation because I really want to recreate that but I don't really anderstand how you turn and how the receiver are. Thanks, hope you can help me !
wow that's crazy i wonder how much more it can climb if you took off the fancy stuff off (it would be lighter but idk if it would affect the grip) (you needed some weight to make the grip work) just a fun idea :)
Now this is something amazing, I'm a keen builder and vehicle hill climb enthusiast. Awesome design and build. How did you do the tracks?most impressive.
Reason this worked: 1 Yes, the 4 tracks DOES give more traction ( aka friction) 2 the tank is quite flat, which means itsvcenter of gravity is low making it less likely to topple over it self. U can also make it front heavy to further improve this feature
Have tried to make the front heavier. Does not work, the current setup proved to be the ideal design. With the cabin on front, there is already more weigth on the front. The reason that making the front any more heavier does not work is that the added weight fights against the friction of the tracks (when the angle is so steep, the weight of the vehicle is almost fully pushing in the vertical down direction). So yes you're right that weight balancing is the key here, but I've optimized the design already for that.
the reason this works in my opinion is because the rubber track pulls itself up on the horizontal tracks. without them you will never get up this steep. (are these rubber mindstorm tracks ??) i like the moc.
@@basberend Disagree. It would climb even steeper surfaces when the surface is real rocky and / or soft. The horizontal 'racks' are an unideal Lego version of a rocky surface.
If you could find the center of mass, you could calculate about how steep it could theoretically climb given enough grip. I’d guess somewhere in the 80-85° range
its somewhat there but isn't exactly built for this but for what? mountain? in real life it would need strong material and its so heavy right now.. idk maybe in the future but still tires cause nasa just developed it but wheels isn't going to help cause its not gripping so there is still a big gap
My children had a toy octotrak that was only good to about 45°. Sort of similar to your design, but with 3 joints, 8 treads and no steering. How many degrees can you hit with another unit? The second and later joints won't need active steering, but will need the rubber band suspension to maintain surface contact.
That's cool and all, but a towel yields to the treads of the tracks... It's like having grooves for the treads to fit into so it doesn't fall. I think a more accurate test would be a solid material. And with the simulated rocks... You might as well just put it on tracks if you're going to help it that much.
Not true. When climbing a muddy hill, the tracks dig deep into the soil. That's what the towel simulates. Regarding the rocks: an actual rocky environment would be easier. Just build it and try it out. Then you'll know.
If this was going to be involving the Guiness book of records, then what is needed is a surface that is standard. If everyone uses the same surface then things would be interesting...
This is very impressive, but I’m afraid that the “rocky terrain” may have offset the results by acting as a ladder. In other words: I think that once the treads found a pattern, it could climb up with ease. I will not deny how impressive it is though.
I'm not faking any one of my videos. It shows simply what happens when all known stuff is thrown away and when one starts with a white blank of paper. This thing was built for the job and it was hard. But it delivered in spades.
896gerard I’m not saying you faked this, I’m just saying that this is so cool and so insane that this is like CGI. this looks 100 percent real and I believe that it is real, I’m just saying that this is so cool!
Really nice MOC. And beautiful engineering behind it. Maybe it is more mechanics (as part of physics) than math, IMO, but I am very interested in explaining it too. (How have you obtained the friction coefficient? Did you some measurements too? )

In first i will which you a happy new year. i love your quattrack and i want To do it the best as i can. i have all pieces but i need an instruction. Is it possible to have some photos or a vidéo which explains a little bit better? thank very much for your help. (I am french so my english is not very good 😅)
Hi Leo: very good that you try to write English ;) Now, you can look for photo's here: www.moc-pages.com/moc.php/435374 and I also wrote a story there. I do not often reply to comments but ah, sometimes...
the head is a bit weight and the body needs to be long for climb and the tracks is just perfect for it also more steeper than that could just be a fall because it became a stick

The road to "simple" is often the hardest to find..
896gerard Well, you did a great job at it
I am impressed by how much you put into your creations!
This blew my mind
tbh a 60° slope is what all military tracked vehicles of NATO have to overcome, so not really special

This is an awesome little Lego Vehicle
REALLY COOL!!!
I also want to go to college in The Netherlands.
You can't learn this on the university ;) This is a unique design.
Well, going to The Netherlands is hard because I live in utah in the US.
I'd use the big plastic tracks and put pins in them
Wow, awesome build! I wasn't entirely sure, but it seemed like the rear set of tracks are powered as well
wow that's crazy i wonder how much more it can climb if you took off the fancy stuff off (it would be lighter but idk if it would affect the grip) (you needed some weight to make the grip work) just a fun idea :)

896gerard time to learn some physics :)
Excellent design! Probably the result would be even better if you have moved the mass centre futher to front

90° :D
If only this was a real vehicle
It is its from sweden and called hägglund
or the russian dt-10
its somewhat there but isn't exactly built for this but for what? mountain? in real life it would need strong material and its so heavy right now.. idk maybe in the future but still tires cause nasa just developed it but wheels isn't going to help cause its not gripping so there is still a big gap
You are pushing it's limits
Imagine the real world applications! You're a pure genius and should work for a heavy-duty vehicle manufacturer!
Things get a lot more complicated when you reach real world scales.
Thats cool and fun. Good work 🦸
this thing is a wonderful slope climber

perfect model . can you please share the instructions
I really wanna see a diagram of the gearing setup on this thing this thing is OP
Perfect model thank you for sharing this video. Is there any chance to buy this instructions ?
Wow! That's unstoppable :-)
Might make an EV3 version, with larger tracks and lower centre of gravity.
I think he just made a truck and tested it on a steep slope as a joke, then he made it his destiny after it worked
Please put together a parts list for us to build
Een mooie Nederlandse creatie, go zo door!
If this was going to be involving the Guiness book of records, then what is needed is a surface that is standard.
If everyone uses the same surface then things would be interesting...
How long did it take to build it??
This is so simple and and awesome
It might look simple but often the simplest looking solutions are the hardest to achieve. Nobody built this before.
Maybe add some suspension so it can climb rocks and other bumpy stuff easier?
The engineering into to this is amazing
We now need a 90 degree angle one
I'm thinking about how to do it, but it's very hard to do with lego parts alone.
who would win? a lonk tracked boi VS a THICC rock boi
Great work
This thing is amazing!

This might be wery dumb, but can you build this out of MINDSTORM EV3?
Would such a vehicle be possible in real life, like real scale?
So it’s basically a Swedish strv 202?
So simple and efficient.
Putting a bathtowel increases the grip, i guesss
I need to build one now
In my mind this is CGI because this is honestly insane.

I want to build this. Can you male a step by step video or give us a Pdf file?
That's amazing!!! Can you give us a notice to build plz?
this is really cool
Can your quattrack beat 120 degree slope?

I love it. smart people like you are awesome. can I have some instructions please I just want to show my mom and dad.
Great project 👌👍!!!
I managed to build a pure 2wd Hill climber that climbed a slope of 74 degrees but it is now here near is capable is yours in other circumstances.
Can you show a photo of it? Maybe a link?

It was like a bull dozer and a snow plow it was amazing
PLZ put that on LEGO ideas!
That's pretty impressive, and... OH MY GOD THERE IS NO DRIVER IN THIS TRUCK
this is very impressive
Damnn I've never watch a lego video this interesting, good job lolll
