7 Types of Wheels and Hard Trials - Experiments with Lego

[@DrEngine]

Any ideas on what other custom wheels would work for Lego vehicles?

[@thewubmachine840]

yes

[@Mr._Bellic]

You could try using a motor to rotate a series of gears that move axles in a semicircular motion, so linear on the ground and then circular to come back around. You could combine this with maybe 5 more to make a walking device.

[@young-aviator]

What if you tried to make a lego airplane that Flys only using lego motors wings can be whatever

[@farmstuckin]

You could try omni directional wheels

[@Fl0B]

Can you do a video about tracks, hard plastics, soft rubber and so on ? With various geometry this should be interesting.

[@garrettcarlson6835]

K but... what if the step master had RUBBER feet?

[@BogWarThunder]

​@@garrettcarlson6835 he probably would have won. His weight was enough to bring on enough tension against his rubber supported contrahend to brake out the defeat for a bit. But with rubber feet he would have had more rubber contact surface with more resist to pull the contrahend right into defeat. It was the literal thing that was missing to win.

[@miyurosewood3837]

@@BogWarThunder real counterpart, a bit more advanced, of step master is known as "dreadnaught wheel" or a "pedwheel", it's a historical predecessor of track. It actually had similar problem as shown but it was successfully used on soft terrain.

[@JS-rv3et]

Ikr these battles where unscientific and biased as hell. Obviously the step master and tank tracked car had better power but the plastic on smooth surfaces VS rubber wheels... like Dr engine never heard of surface contact before.

[@Tom89194]

Yeah, the track machine and stepper were done dirty by the smooth slick surface since they have hard plastic feet.

[@robertrohrer8535]

Making the tracks out of 3d rubber or even just the slices would have been a nice idea and more fair for the tug o war part

[@BogWarThunder]

I totally agree. Not just the DualTrack Dominator was my clear favorite but that would have been the perfect addition. Not just that it adds more weight to the vehicle but it would master every of these challenges without even thinking about struggling in any perspective. The only thing that could have stopped him then was speed.

[@AthiosDvK]

I rly liked how the DualTrack Dom came out, it's my personal favorite the extra room on the top might allow for some excellent cabin designs for the crew

[@No_Way_NO_WAY]

This comparison was kinda unfair. 😅. Some had rubberized wheels some didn't. Some had open bellys some hadn't. Especially in the tug of war, the vehicles with rubber easily won vs ones without. Giving the StepMaster rubber shoes, probably would have made him at least 3.rd place.

[@roymuerlunos2426]

The tug of war really just demonstrated the idea that on a flat surface like that, rubber tyres have better grip than other things.

[@Arct1cW]

9:00 StepMaster turned on Michael Jackson mode.

[@althejazzman]

MoonMaster

[@garrettcarlson6835]

Yup! Looks like we all need a second video, but with all of the vehicles carrying their own battery packs and fully equipped with rubber feet! Especially for the step master. Maybe using boat-shaped feet for the step master. Like, make it flat, but with a very slight boat-shaped curve on the bottom. That would make it comparable to the traction the beetle gets.

[@garrettcarlson6835]

Or cylinder-shaped, I don't know which one would be better.

[@Delendar90]

Dont think i have ever been so invested in performance comparison of silly lego vehicle competitions.

Model "Golden Grip Snail" the best and cool! I like it😊

[@DrEngine]

Glad you like it! Thank you for watching ☺️

[@RaidFiftyOne]

Yes it was my favorite and stepmaster was a close second. I don't care what anybody says the Golden Grip Snail is perfect in every way. That beetle probbaly cheated in tug a war because it was desperate.

[@CiarraHarrison-le6pz]

Be honest, the step master is my favorite because it’s kind of cute. Just add a little face onto it and you basically got yourself a step master pet.

[@mouse_cop]

This video proves that tanks are awesome and should be road legal 👍

[@darreideamos2309]

there is a reason us humans use tracks for heavy terrain and this was a nice showcase. And these tracks were made out of slippery lego plastic. A proper more grippy material would show true power of this indominable way of transportation!

[@undead.rising]

So basically, the Siege Strider was useless in every single respect.

[@knalltutemichl3473]

No it wasn’t: At least it was a good example of what doesn’t work ☝️🤓

[@coldlogic8792]

Would replacing surface contact materials mean classifying them as a different type all together? Like if we added rubber soles to the StepMaster Cruiser or made exact replicas of the Beetle Bot's tires only with them made with plastic? I wonder how different the results would be if every part of every mechanism that made contact with the ground were of the same material.

Tug of War would have been more fair with a force meter mounted at the same level as the chassis, and all vehicles having rubber traction. Like the 6x6 was being pulled upwards from the back

[@satibel]

I feel like the chain in the middle on the stepmaster helps quite a bit on the tire section and especially the siege strider would fair better with a similar system.

[@michaelkowal3230]

Golden grip pretty much dominated, it only lost to the beetle in tug-of-war because the solid, flat terrain gave the beetle an unfair advantage of more traction

[@justjay4586]

Altogether, my favorite was the DualTrack Dominator! I also love the Milky Wheel custom; what a great pun.

9:31, 9:42 - clear influence of tread and surface grip quality

[@CloutmasterPhluphyy]

Golden grip, milky wheel, and stepmaster are the only correct answers. They won at pretty much everything until beetle came back in ToW

[@JarodSherwood-s6g]

The GoldenGrip Snail was actually very good, because it has bigger wheels, it has more space on the ground. The "DualTrack Dominator" could be a lot better if: You added 2 springs in a V shape for each axle, made it a single track, and found a rubber-like surface to attach to the tracks for grip. Basically, make it a tank. - Something completely unrelated, if you added pontoons to the creation (with my addons, of course!) then added a retractable propeller, it's a boat :D - EDIT - offsetting EACH stepmaster's wheels could alter the performance on the steps and hillclimb!

[@freeidaho-videos]

Fun to watch, but hard to draw conclusion from. The difference in ground clearance, distance between wheels and gear ratios made significant differences in performance.

[@texasgrillchef8581]

A lot should be said about the rotational diameter of each wheel type over the various obstacles. Larger rotational wheel diameters will almost work better over smaller rotational diameter wheels.

[@gsestream]

milky for the win

[@danielrobinson7872]

The tug of war test was too in favor of the rubber wheels because of how smooth and hard it was. A rubber mat would have been better. My favorite will always be treads. They are the ultimate in all terrain movement.

[@CGFun82]

Triangular catterpillar track treads. Really big soft wheels. Cylinder wheels (many wheels on one axis like some agriculture tractors have)

[@spiceracksargent0014]

Gonna be honest, StepMaster Cruiser and DualTrack Dominator are tied for the top favorite slot in my book.

[@REOBrickfilm]

good idea

[@Runescope]

Give the "Stepmaster Cruiser" some traction instead of super smooth feet and it'd probably walk over everything in the tug of war. (See what I did there?)

[@MONYESTER]

Goldengrip snail and milkyway are both amazing, they did all challenges and are strong in the tug of war.

[@brizkt7480]

Some of these have little to do with the wheels, but everything to do with power to weight distribution and traction to surface area ratios.

[@Preecy]

golden grip snail, an engineering marvel

[@cameronneveu7277]

Rubberizing the Smooth Plastic Grippers would have helped (Rubber Cement or Rubberizing Spray), also Differentiating Terrain would have yielded different results, as certain forms of movement are favored. It would be great to see these Vehicles in Difficult Terrain Trials. Smooth (Steel, Plastic), Low Friction (Ice), Soft (Sand, Loose Dirt), Hard (Stone, Asphalt), Wet (Deep Mud, River Crossing w/ Current) [Not Sure How you'd do that, but it would be neat] Also Speed is An Important Metric for many Vehicles, sure it can make it over any terrain but could it be used in a situation were time is an important vector like an emergency?

[@Joaquinmuñoz-o3i]

Poor siege strider 😢😢

[@connorlarson7390]

I feel like the dual track dominator would fare a bit better of the plastic wedges were rubber, since it looked like the DTD lacked grip on the TOW.

[@codychickadee5095]

I think the GG snail is a solid design, it's like a SHERP. The beetle was also a fascinating concept along with the stepmaster! Siege strider may do better with a speed reduction. Such a fun video this makes me want to go invest in a bunch of technic.

[@enyu3591]

Try tank type wheels and a stronger gear ratio for each one. Plus, you can add better and equal grip for all of the machines.

[@Steppenkater]

Put some rubber on the pads of the DualTrack Dominator and it's almost unbeatable. Also the Milky Wheel is incredible. It just need some stronger gears that don't slip.

[@Franimus]

My favorite is the milky way. How does it perform in reverse? Do those wheels have better or worse traction when turned around?

[@godblessamerica99]

Let's be honest. It all comes down to the skill of the driver.

[@robertlandrum]

I think if the skids on the bottom of the Dual Track Dominator were TPU, it would have held on better and beaten Beetle bot.
