Are there any ideas about the name of the last model that will better describe its functionality?

I love how customizable these Lego vehicles are. You can mix and match different parts to create your own unique off-road vehicle.

This is a good argument for why we never evolved to have wheels instead of feet...

I would focus on refining the Tracker model. Maybe add a reinforced stepper component instead of mixing all three in. Tracker was most successful in terms of stability and speed while Stepper proved to be quite adept at traversing rough terrain. Encasing the threads may prove effective in preventing "quicksand" from getting into them and impeding mobility, but that's just a thought. If the test is just figuring out which system is most successful regardless of speed, then using Stepper as a base seems sound enough. As for your question: I would vouch for "Composite"

The attention to detail in these Lego vehicles is impressive. They look just like real off-road vehicles!

That is why a caterpillar type of movement was chosen for tanks and all-terrain vehicles. And the test "Great hill" must be driven at low speeds.

These Lego vehicles are so much fun to watch in action! It's like seeing a real off-road race, but with Lego vehicles

I know im late but this guy can make an functioning ATAT from star wars out of lego

This guy never runs out of mechanical ideas

the light brown things from the tests looks like the food of my bunny

The Mixer is what happens when Dr. Seuss is your lead engineer.

1:38 I love how it faceplants into the canyon

i think that Stepper if made the same length as the mixer , or if consist of 3 Stepper modules, it would pass the great hill test. The biggest advantage of the Mixer is the stepper module at the back

The walker one is just like one from Scrapheap challenge years ago. Ah memories. Annoyingly that episode doesn't appear to be anywhere.

Bro got the turkey feed out for this one.

You managed to combine them in a way that uses all their strengths, really cool 😎

“What if I just add larger wheels than the obstacles themselves?🤔”

I Love That You Added Er To The End

Interesting use of horse feed

But heres the stepper. But heres the wheeler. But heres the tracker. But heres the mixer.

The "Mixer" Lego vehicle is particularly impressive. I can't believe how well it can navigate through tight spaces.😮

These Lego vehicles are amazing! It's incredible how well they can handle these obstacles.

The attention to detail in this Lego Technic video is incredible! The vehicles look so realistic and the obstacles are challenging.

I wonder if you mounted the battery pack on the uphill side of the vehicle if that would help it climb the Hill

The stepper design reminded me of a rescue hero toy I had a kid. It moved in the exact same way, you even reposition the legs

The tracked vehicle would've passed the great hill test had you put roadwheels on it and a track tension adjuster If you look at a tank, you'll see several kinds of wheels on it. There's the drive sprocket, either at the very back or the front of the tank, and it's the only wheel that's powered by the engine. Then, you have the road wheels. These are the wheels that actually hold up the weight of the tank and distribute the weight of the tank evenly so that 1. it doesnt sink in softer ground, 2. it has maximum traction. After the roadwheels comes the idler wheel, which is usually where track tension is adjusted. Tracks too tight: Lower HP:power ratio and tracks more likely to break. Too loose: teeth on drive sprocket likely to skip and grind on the track. And.the return rollers, which keep the track from hitting the roadwheels as it returns to the drive sprocket. Your tracked vehicle could use a tension adjuster and some roadwheels, and it'll do just fine over just about every obstacle here

Can you build model rover ? Different rover of many terrain

I like the first one cuz is cute

combine the tracks with the walker to get a walker with tracked feet lol

I like how he names the tests, it makes it feel like a video game

🤩 The landscapes are stunning! It's like they were filmed in a real off-road course.

I like the stepper. Very original 👍

So it's either the stepper or the mixer... I'd never guessed

Amazing designs can be made from Lego pieces. The guys have creative thinking and fantastic ingenuity. I love your Dr.Engine channel.

what kind of ungodly creation did you make at the end? that wasn't a combination, that just forced everything together, regardless, great work and I love it. It worked so well, the cliff when the back came off was funny

The first one felt very similar to a baby sea turtle trying to leave a beach.

Couldn't help but notice the little Warcraft reference to your second terrain test "Thousand Needles" hope I'm not the only one who caught that!

Enjoying my dream with your videos. 👍🤗👍👍👍👍

If they didn't get mixed into a super vehicle, the stepper would be the best choice to use to travel off road, it's slow but will get you places except steep hills

The last one looks like what you'd build in Rovercraft 😂

I wonder if the first design would have made it if it had 4 'sleds' instead of 2. Or maybe just 3. The one or two in the center would rotate down just as the outer ones are moving up and prevent it from sliding back.

Amazing job, dudes! Keep going!

Make an Ice/Snow runner using the wheels you made at 4:37. Make a 3x3, then 4x4, up to like 10x10 AWD. Test studded tires on ice

This guy makes the best Lego technic vids

Stepper one would be an amazing Bionicle Rahi set!

You made me remember something........... Did you watch Hot Wheels Acceleracers? There are episodes where the pilots find Alien vehicles called "Hyperpods" to overcome some obstacles. Can you recreate those and test them out?

This is soooo coool!

I built the Powerfunctions Bulldozer a while back. It was extremely heavy, yet had absolutely no traction in our yard wherever there was cut weed stubble. The stubble was only about as high as a LEGO brick, but as heavy as that Bulldozer was, it simply couldn't get any traction.

The mixer looks like something out of a sifi movie

I never would have thought that Lego vehicles could handle mud pits and rocky paths like this. I'm definitely impressed.

Thought you were going for the active variable track geometry approach and was interested in how you would accomplish it

When Mixer breaks in half over the Great hill . . . Video: "Pass . . . Fail?" Me: "Pass . . . (Kind of)"

asmr😊

Your design is so amazing. Great job. Keep going. 👍

The military called, they want their engineer back

We need to put this in the Lego treadmill

The mixer is the Frankenstein of Offroad vehicles

technically the tank passed the great hill, it reached the top

The mixer looks like something straight from the military like if you add a tank turret it will become a real tank

What is that stuff your using as the terrain

Brilliant! Continue in the same spirit!

Satisfying lego click sound

Nice vid 👏 Love your work

Fun fact: In 0:23, the stuff that he pours in are Guinea pig treats.

They are so cute 😭😭

To make your test results more sound, you would need to run all tests again after you made a new version. For instance, a later version from Stepper might again fail at Thousand Needles. 😉

Pls make tanks

my cat approves of this video.

The mixer looks like something from Dr Suess

Excellent video!

First car test be so funny❤

These Lego things is got an umbilical cord like an Evangelion

How do you decided when one fails vs when one is allowed to get upgraded so it’ll pass?

Круто

8:07 that's muscle memory

The wheeler car sound like dacia sandero 1.2 16v

too good!!!great!!! I will try to imitate you in my channel

Keren Bosque Salam dari odong2fishing

but bro, the last one is just bigger that isn't comparable

Gran vídeo 😃👌

It's kinda like I'm watching the evolution of an animal

How many pets do you have to have that many wood chips lol

I like that challenge!

How much lego parta do you have? Dr engine: Yes

good moments asmr !!!

Would the tracker do better on the great hill without the spiked tracks?

When he mixed all cars in one I was like wat is that?

0:17 real footage of what baby’s look on the inside while crawling

1:52 the forbidden piece😭

Very good ideas of passability. Also implement Tatra technology with a rowing system.

What a contraption at the end! I love how the stepper is just tacked on to the back, like some aftermarket trailer.

Weird how the stepper stick can correct itself to go up hill in the first place if not ascend.

YESSSS

My question. Do the later designs work on the earlier tests?

Needed a 6x6 wheeler instead of 4x4 with such a long wheelbase. Also, note to self, tracks hate quicksand.

I'm pretty sure I saw the mixer used on a ww1 tank before

The stepper could've passed the great hill if you increased the grip under the main body 😭

The wheeler didnt get as much modifications. Not fair. With a set of extra wheels it could have made it through the needles

Ahh yes, the classic traeger pellet test, 😂

Just a question could u have done the same format but put rubber bands?
