Impossible CLIMB - Experimental Lego Vehicles

In this video, I will show you how to make a Lego vehicle that can climb off-road slopes. I will start by building a simple vehicle and then test it on a 20° slope. I will then make modifications to the vehicle to improve its climbing ability, such as adding better tires, lowering the center of gravity, and lengthening the wheelbase. I will continue to test the vehicle on steeper and steeper slopes until I reach the limit of its climbing ability.

For the tracked vehicles, you need to have gears pressing down in the middle of the belt too.

Not only is backward driving legal, it is a common technique used by off roaders.

I feel like a longer version of Track-and-rola would do better, especially with road wheels to keep the track flat with the ground. You could clearly see the track in the current design not properly aplying presure in to the ground.

Please try this! I think a vehicle with almost comically long tracks will actually perform very well. The biggest obsticle is either that the wheels simply dig in the "dirt" instead of making the vehicle move forward OR it tips over. I think really really long tracks will solve both problems, since with tracks that are say 3-4 times as long as the vehicle itself it gets a LOT of surface area, which counteracts the digging that wheels tend to do, and because of the length and center of mass it wont really tip over.

My vote is definitely for Track-N-Rolla, but would love to see a projectile+winch based “sled”!

The creativity in your Lego MOCs is inspiring.

[jordandrescher]

on the tracked machine, the only way to make it work as intended is to attach a series of rollers to the bottom of the frame, maybe your typical tire to stretch out the track to make it flat, without this, there wont be any weight dispersion and your tracks wont have any flotation, in short, think of a tank, or a bulldozer. hope this helps

[colbycramer]

Old Ford model A’s you would sometimes have to drive them backwards uphill because their gravity, fed fuel tanks would not allow for proper fuel flow past a certain degree

[pbbshorts]

Track-N-Rolla was the only one that made it to the impossible 25 degree angle climb so Track-N-Rolla

[MEERKAQ]

You should have given the tracked one road wheels in bettween the sprockets to it could even out more preasure

[Olive-oilien]

Wheelbase would help significantly here. With that, proper floatation and material displacement to move you forward this could have easily gone up the 25 slope. Still, I love what you did here.

[DrEngine]

What kind of model did you like the most and why?

[marianorodriguez]

DrEngine please tension your chains/track more. It will mean there is less slip like with the tracked vehicle.

[paulosborne]

Several of those designs took advantage of the retaining batons under the surface of the cork chips, therefore their climbing abilities are invalid because they took advantage of tractive assistance the other designs didn't use.

[Ding_Bat]

The tracked vehicle requires rollers. These rollers actually carry the weight of the vehicle, and thus spread the load across a larger part of the tracks, and thus the ground, which is what you want.

OFF-ROADER ROLLER!!!










I guess its just better!

[ngvincent]

The real difficulty is not only the slope, but also the looseness of the road. I wonder whether there is any vehicle that can overcome it.

[osck]

did you really went piece by piece 💀 instead of using a blender?

[devharwani]

Your work is honestly underrated. It is amazing to see your efforts not only in the builds and recording but also the editing overall. It just adds so much attention to detail 😄

[RyanWithAviators]

A longer wheelbase tracked vehicle with bogey wheels midspan in the tracks between the two end sprockets would help with lowering the ground pressure, and it won't flip as readily.
