Quattrack | The Ultimate Ultra Steep Slope Climber! 

The road to "simple" is often the hardest to find..

896gerard Well, you did a great job at it

tbh a 60° slope is what all military tracked vehicles of NATO have to overcome, so not really special

@@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.

@osmacar If it so simple if u can make ur own lego technic vehicle that can do that I'll pay pall u £50

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...

i'll say it again, great work! and a nice challenge

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.

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.

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

Things get a lot more complicated when you reach real world scales.

896gerard time to learn some physics :)

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.

@@896gerard thx 4 explaining

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.

It might look simple but often the simplest looking solutions are the hardest to achieve. Nobody built this before.

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!

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.

90° :D

I'm thinking about how to do it, but it's very hard to do with lego parts alone.

@@caedenthefarmer9918 I have no idea sweetheart, I posted the comment 2 years ago and Arming Hacking left the chat and took his damn comments with him so I guess we’ll never know what the hell my comment meant 😹😹😹

Can you show a photo of it? Maybe a link?

@@896gerard Unfortunately I haven't made a video or a file on it but I could send you a picture on another social media.

No.The vehicle is still stable. More grip will be needed.

@@user-cb5cw2mg6j im staying with what i said.

Very similar

That's what I thought
