7 Types of Wheels - 4 Hard Trials - Experiments with Lego Technic

I tested seven different wheel types and shapes in four challenging conditions. I was curious which wheels would be more effective - standard Lego wheels or custom ones?
Write in the comments if you are interested in models for 3D printing of custom wheels - I will post the information on my website.

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

[@OverTheHorizon840]

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

[@user-mx3wt2wt9e]

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.

Should have done a supplemental tug-of-war in loose soil - hard and smooth surface was unfairly biased to rubberized wheels

[@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

[@roymuerlunos2426]

StepMaster Cruiser won on style alone, I mean, did you SEE that moon walk in the tug-o-war?

[@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.

[@zenbonimusic7308]

I think if beetle bots signature motion was mirrored in it's rear it would have stood a better chance. Definitely a unique concept!

[@tetyanazayatsteza2406]

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.

[@ZILOOOOO]

@@RaidFiftyOne bud the beetle was made for smooth surface. tug of war was its time to shine

[@HenrikMyrhaug]

I feel like the stepmaster could be so much more effective with "shoes" in its feet.

[@shingshongshamalama]

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

[@coleawesomeify]

Put some rubber pads on the stepmaster's feet and do the tug of war again.

[@garrettcarlson6835]

They'd have to be rounded on the bottom for the step master to stand a chance. If they're flat, the distribution of force will be spread too thin. It needs to have a needle-like contact force with the ground for best traction. And as it was mentioned in another comment, having it's own battery pack installed would help add weight.

[@BuilderBasti]

My favourite in this one is definitely StepMaster Cruiser! Such an interesting and playful design, working really well, except for grip being low

[@ZuoKalp]

I absolutely loved the dualtrack domintator design.

Watching milky wheel and stepmaster makes me wonder how scaled up versions of that kind of design would work in real life. They just were so good at tackling obstacles. It makes me curious.

It would’ve been even cooler if you had showed all the vehicles and the terrain and then let us make our predictions before seeing the results. That way it would be more interactive

[@depeltenburg6916]

This need a second one. Before my vote I want head displacement, wet muddy ground. Water axel high on stone surface, water axel high on muddy bottom, ice flat surface and top speed.

[@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!

I kind of like the one with the big wheels originally designed for bearings, but with rubber tread it became really cool

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.

[@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.

[@uniquely.mediocre1865]

Okay but I love that the big winners were the steampunk-esque wheels like the goldensnail (which was basically gears for wheels) the springy spiral wheels, and the giant stepper, like it honestly gives creative inspiration

[@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.

[@FlakManiak]

The StepMaster Cruiser has captured my heart; I was rooting for it 200% in every category.

[@user-qo3yj1vk6v]

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!

[@ggroombr]

The golden snail is essentially just a Sherp ATV. No wonder it did well!

[@CloutmasterPhluphyy]

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

[@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.

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

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?)

[@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?

[@protoman4622]

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.

[@Hoshimaru57]

I’m disqualifying anything with 3D printed parts because not all of us have a 3D printer. So I’m going with the Stair Master because it handled everything you threw at it, and despite being at a significant disadvantage on a smooth surface, managed to hold its own against your Golden Gripper.
