Ok then so you use pedals to move forward use the gearbox to switch to C R A B D R I V I N G Edit: HOLY SHIT 300 LIKES!?!? I LEFT IT SITTING THERE FOR 5 MONTHS Edit #2: Nearly 1k likes, man...
There's been cars in the past that could do this. Various different designs in different eras.
Even blond girls could park without accident

@@Hawk7886 it's not sexism it's humor... my girlfriend drive actually better than me... if you can't understand humor you can just remove that wooden stick from your @ss
If lego don't turn this into a technic model they've lost the plot, you deserve all the royalties too. Absolutely amazing build, I'd buy it.
Shut up and take my money.
It would need changes to make illustrations on a building manual easy to understand, and things like the tyres would probably have to be special pieces to make it work well on common flooring materials even with dust or animal hair. That said, I can totally imagine this as a set with a top that makes it look like a sci-fi muscle car from a cyberpunk universe. Love the sound of those electric motors whizzing away.
Well, at the beginning of the video the balls were specified to be Duplo brand. So that's Lego's big ol' toddler blocks division. I don't see any reason why they couldn't just produce them in black for the set. Maybe they would need a rubberized finish or something?
@@HiiroRocker101 they would probably need the rubber coating,for extra traction / grip / whatever.
@@xx_worldjaxx_xx1494 Rubber coating and possibly treads cut into it, not unlike tyre treads IRL, but probably in a hexagonal pattern. Anyway, I'd definitely buy this, if it were a kit.
11:32 > "Dust sticks to the drive wheel and makes them slip" cries in "90s ball mouse"...
My middle school robotics team built a robot with a design pretty similar to what's shown at 1:50 for the 2009 First Lego League competition. We had two wheels connected to the NXT in the front & used the duplo ball in a cage at the back. The ball would roll around freely so it reduced the amount of programming we had to do. It's so cool to see a much better version of the dulpo ball wheel concept all these years later!!
Frc uses swerve drive which is similar liar to this
@@its640am yes, but it's not really the same. but would be interesting for someone to attempt something like this
@@its640am Swerve drive is similar in function but WAY more mechanically complex. Honestly, anyone who uses it is basically throwing money at whatever problem they're trying to solve, rather than being resourceful.
I’ve seen some ftc teams make ball drive as well, though it’s not very popular
No obnoxious music or talking, just the sounds of Legos clicking satisfyingly.
This is my kind of ASMR.
Almost as good as Lego building IRL.
I mean yeah, its a ripoff channel of Brick Experimentation Channel that has been around for years.
@@thecrazything95 Ripoff is a surprisingly dramatic term for an amazing concept catching on lol
The only annoying noise is the motors high pitch squeal.
that's pretty cool, and the finished product looks like an actual technic set, great stuff!
Looks better than any recent technik set. Technik is in a real sad spot right now
Better technik is Trash nowerdays
I just throught of something... Can technic sets be accepted into Lego Ideas? Like, they already had some complicated sets there and why wouldn't this Piece of Magic be there
@@alwexander996 Lego is a shitty company there a so much better companys like xinbao or cobi
@@jasonbrody9294 That’s not entirely true. Yes, they have been pushing sets more recently, which tend to be same-y, but the quality of the pieces and the consistency despite the variety of parts is surprisingly high. Compare that to other companies, which use weak locking bricks and a very basic set of pieces, and you’ll see that LEGO is generally a better option. Also, LEGO’s developing biodegradable bricks at a similar quality, which is better for the environment but comes at a cost to them, unlike the Chinese toy companies which only really care about profit.
Suspension can be added if you separate the wheel "modules" and add suspension to the module itself, and braking can be added as a brake drum on the wheel itself, or by adding a short reverse burst (adding ABS might be harder though because of the omnidirectional thing) Awesome video! Part list, maybe? 🥺
ABS could be controlled via electric motor modulation in software.
Suspension can be added by just using inflateable wheels instead of plastic.
Our poor ass
@@cheesebusiness Racquetball balls would solve several issues, from suspension to static build-up or dust.
I had this thought aswell but the unsprung weight is still quite high in comparison to suspension wheels
This is a really well-made video for all us non-lego technicians, because of how he explains what he is doing and the purposes of gears and explaining problems, also informing us what he is using and even adding arrows occasionally. Really fun and interesting channel, you have earned a sub
The most amazing thing is that even if LEGO never intended to make those balls to be used like you did, all the engineering behind the craftmanship of the bricks make this absolutely possible.
Ohhh Ganesh ! c'est ca qui est beau avec les légos c'est de détourner leur utilisation principale
engineer : give me something, and I'll make it wonderfull
Oh vous ici, quelle surprise :) A quand le "Apprend à imiter une brique Lego" ? :p
.... is y the toys exist
Lego is all about breaking conventional rules
This is a perfect example as to why they don't make cars like this. The added complexity doesn't make up for the small amount of extra advantages.
this project is incredibly cool... but imagine the contact patch on a wet/icy road lol
@@FreshApplePie Tokyo Drifting to the graveyard
@@FreshApplePie imagine any one of those parts breaking at speed.
Imagine replacing a “wheel”
Also, grip levels will be smaller
This is easily one of the most amazing LEGO builds I've seen yet.
Love this one, such an incredible build! If you ever do a redux of this, it would be cool if you marked dots along the 3 axis of each ball, so when you're showing the turning demos it's a little easier to see how they're rotating. Awesome video! Thanks you!
You could use rubber balls as wheels, such as bouncy balls. They'd have better friction both to the ground and the drive wheels. They would also add, depending on the stiffness of the rubber, a certain amount of inertial dampening as a suspension. A awesome build.
Good idea but with the plastic balls the car is able to drift smoothly
@@Arjun-ei3jx with enough torque and skill, you can drift rubber ball wheels as weell
@@Arjun-ei3jx it drifts bc of the 4 wheel steering, standard AWD tends to understeer
the dust issue will be worsened, need to mitigate that.
I would imagine that giving the driving wheels some angle pointed downwards would give it suspension through the mechanism that also keeps puts friction on the ball and drive wheels, and have that be the only point of contact. Though the ball choice would certainly influence the traction characteristics and soften the ride as well. Perhaps those pink super bounce balls would work well.
One change I would make would be to draw circles on the wheels/balls so that we can better appreciate their rotation and how they're affected by the motors. Great stuff!
I guess, the motion of the vehicle seems explicitive enough.
@@sashaherriott5129 Diego probably means in the parts where the vehicle isn't moving, and the effect of the motors on the ball rotation is being demonstrated
A 3d circle
Don't you mean a line?
Maybe even flimsy rubber bands for extra grip / traction
Great mobility within an open space. I'm seeing possibilities for carts, particularly in a warehouse-like setting. Would also be responsive for park/lot/field security, especially when in groups. Less traction and softer surfaces may also be appealing for groundskeeping vehicles. Perhaps if the ball was lightly textured for grip, like a dodgeball/stability ball?
aahh....these lego pieces clicking in makes such a satisfying sound.
Reminds me of the car Will Smith drove in the movie "I Robot". Very well engineered.
Certainly. Put an Audi badge on it and they're very similar.
@@Xtoxinlolinecronomicon sorta it's just the design, Cooler to add the working backwards doors like on the Audi to this Lego car

Very cool to see in practical use-and understand a bit more about the feasibility at larger scale
it would be interested to see a model flying car made with legos in your style! Your mechanisms are impressive, and so is the design of the finished build!

I hate that I hate Technic and can't bring myself to do stuff like this! Well done man, it looks and works amazing!!
My heart broke when you said you don't like technic in one of your videos :) Thanks for your feedback, means a lot to me coming from a lego designer.
You know..... lego Technic is very cool but its too expensive
Knex...
"I hate that I hate something" is probably the silliest thing I think I've ever heard that did not come out of my girlfriend's mouth🤣... it sounds like the words of a true uber hipster contrarian. I'm a die hard knex lover and if you want to build large scale stuff or impressively functional weapons (particularly compound bows that actually flex like a real bow) or really fast elastic powered cars knex can be superior but technics are so popular there's a part for literally everything now (which is why it's kinda cheating; u want a worm and wheel gear box? Just buy one) .. the variety of parts and level of intricate, functional detail you can achieve on such a small scale with technics is unmatched though... You certainly pay a premium for it and that is why I love to hate on Lego.. if I want to build cool stuff out of plastic nowadays I think a 3d printer is where I'd start and basic rc car stuff is so cheap now there's no reason not to go that route
@@ianbuilds7712 sounds like a lovely relationship you have there 👍 why even include that lol it just makes you sound a bit shitty ngl
This is amazing! Would love to see this tried with rubber balls for added traction and shock absorption
I’m so completely impressed with everything you make man! Just insane. 👏🏽👏🏽👏🏽👏🏽
they should definitely make this an official lego set. Amazing design and functions!
Agreed. It's been a while since LEGO did anything even half as innovative.
@@macsmith2013 latest Lego technics is putting a hat on a Lego man
fr with more color besides shades of gray, this absolutely should be an official set
I agree
So double steering makes it an AWD but then the car steering makes it a RWD. That's interesting. I like that you also used the crab steering concept that people thought of irl with cars such as this :D Great job! (Just an edit here about my comment: Yes I have realised it's supposed to consider the steering and not the drive since it still uses all wheels to drive but can change which wheels it uses to steer, thank you to the people who were correcting me in the comments.)
Nah it's AWD all the time. All 4 spheres are spinning even in car steering mode, which techinically makes it AWD. The word you're thinking of is 4 wheel steering. It already exists on some cars, and cars even from the 80s, but the spheres in the video just takes it to the extreme.
Crab steering as an extra slider in double steering mode would be sick for parking.
Double steering makes it 4WS 4 wheel steering
The "crab" steering is what I was waiting for as soon as I saw this. Freaking awesome!
@@MaxUgly crab wheels actually exist but mostly in robotics and AGVs in ur shipyard
I like the ball-tire idea. It's an interesting idea. That could maybe work well on these new reverse trike vehicles that are coming out now.
i dont see how the break sistem would work with these especially with high speeds
Fun fact: If you replace the motors with turn sensors, that's about how old school computer mice worked.
Mice had X and Y axis, this is only one way (like a wheel) and I only looks cool
Beautiful, throw a motor in an old ball mouse and let it roam around the room for your cat to play with!
@@jek__ I have one of those old mice. Now I want to do this. One problem… my cat’s old, and doesn’t chance things.
@@raymonddamm8559 but... it does have 2 axis?
now that makes me think... You could technically program it then to map your room / route that the vehicle is taking, and have it transferred to your computer
Incredible! The fact that sphere wheels can be better then regular wheels is surprising, you'd think it would be too hard but youve shown it isnt =D
it would be on a 3000 lbs car. but on a 2 lbs of plastic yeah its ez
spherical wheels are great if you don't have to worry about surface wear or traction
@@MagnusFeirenbacher what about dirt getting between the drive wheels and the ball
@@MagnusFeirenbacher well the good year tire concept would rotate them periodically for even wear
@@RyanSmith-wc7ku Yes, but the issue is the sphere will always end up with substantially less surface area on the ground than a normal tire. Surface area is critical in keeping your grip in all situations.
The fact it looks just like a cyberpunk car... Well done...
Now this takes 'balls of steel' to a whole new level.
If Lego doesn't make this into an official set I'm gonna lose it.
probably wont due to how much stress it put on the ball pieces sadly
I don't care, I want one!!!!!
@@Xsoskeleton ballshit
Youre gonna lose it
If it would be launched by LEGO it would probably cost a fortune. Would be at around 400 USD I guess.
This is a great project. Your ball wheels seem to be a simpler and better solution than ALL of the omni-wheel implementations I have seen. The crab and sideways translation modes were hyper-interesting. Nice going! I would love to see this with equivalent-sized rubber balls, or even what they call "Super balls" or "high-bounce" balls. I subscribed immediately. All good wishes, my friend.
I was also going to suggest the hard 'super-bounce' type balls, as they are usually very round, and would provide better power-transfer & traction.
@@WhiteWolf65 Are we talking vulcanized rubber balls like those that are used in Lacrosse? If so those balls are incredibly dense and have significant weight to them. It would be very difficult to stop the vehicle quickly and change direction because of the momentum.
Omni wheels have better performance when scaling. Otherwise we'd just use balls for everything
super balls bro
@@jiquandaviussongaming8640 this is a family friendly youtube channel
this is the coolest thing i’ve seen all day! this seems very complex so props to you! i wonder how we could take this concept and turn it into something for humans to drive.
0:04 Okay, it works. We’re done here.
😂😂😂😂
This is an ingenious design along with the three drive modes incorporated in the design! It reminds me of the car is I Robot! Outstanding creation you are very creative!
I was about to say the same thing!
That's likely the inspiration.
i was watching the video and also reminded of that car. It's an interesting concept
I wonder if spherical tyres could be possible in real life
@@aestheticswim3397 i think that biggest problem is transfer of power to a ball. With a wheel its easy, but with ball not so much :( for now only with rolers like here or old computer mouse.. Imagine hard breaking.
People are saying "I, Robot," but my first thought was the DMC-12. Very cool build! I wonder if the "dual steering" would have functioned more like what actual cars have if the wheels were grippier?
Same 👍
"If my calculations are correct, when this baby hits eighty-eight miles per hour... you're gonna see some serious sh*t."
Yup. It's an Audi car in "I robot"
Wait the DeLorean had ball wheels? or are you referring to the chassis/styling?
@@paulstein8854 Chassis/styling. I've never seen a full-sized automobile with ball wheels! 😅
Ball Wheel Drive... love how well this works. Well done!
Not only is this educational and cool, but I can see this being a potential future for automobiles
When I was a kid, I had a Hot Wheels magazine that showcased the car used in I, Robot that had a similar ball-based drive. It was so cool. This is basically that car brought to life.
The dream drift car. You can literally drift at 1 km/h. Plus no excess wear compared to normal driving.
I always thought vehicles of the future may incorporate a round rubber ball into a driving or controlling wheel especially if you had four at the corners where wheels would be. It’s an interesting concept. I love the way it turned out!!!!
I have seen the Goodyear sphere tire prototype years ago. Always wondered how it could work in the real world. Now I know, thanks :)
Finally, a worthy use for Duplo parts Mighty impressive, my dude!
11:53 Can be used for astronaut training lol
Petition to make this an official Lego set =👍
What u did here show the world that the future is here, the future car should be based on this model. Great job
10:45 ngl, that really sounded like a tea kettle
Good donuts bro 9:40
Some absolutely sick drifting in this
This video should be classified as ASMR, the clicks are so satisfying
I am fascinated by your skills. The whole process of developing looks just easy - yet I know it was probably not. And the result looks also very professional. Was nice to see how you integrated everything in a very compact way. Thanks for sharing!
I mean, it is professional
same chassis may be used with either tank turret or car cab
perfect for drifting
I want to see a phonk music video with this car drifting
Drifting to heaven
Absolutely the future of personal vehicles. Love it. Well done.
Dude! That is some beautiful engineering! And the look of the car is pretty nice too. It just moves in such an alien way. But parallel parking must be breeze.
Fun and interesting! As a FIRST Robotics Competition vet my favorite control scheme is definitely Crab Steering, because *precision.* That said, can you imagine trying to get into this thing and being told "you have to sit above the window line, the entire rest of the car is engine block and steering"? Just made me giggle.
I've seen a lot of pictures of concept cars with spherical wheels. It's amazing to see a working model of it though! If anything, this definitely proves that such a mechanism is very much possible.
Facts I was so hyped when I saw this vid
@@MidwestFarmToys steel speres with rubber coating.
@@MidwestFarmToys time to find out how they did it on the balls from those ball mice.
@@JohnCena-iw2vk See, those are just entirely made of rubber. Which, at the speeds you move a mouse around, is fine but once you put that on the road, you'll just sand off the wheels until they're too small to make proper contact with the drive wheels or your car just hits the ground and then just sits there.
@@JohnCena-iw2vk Buy 4 mice and make a new car
"When This Baby Hits 88 Miles Per Hour, You're Gonna See Some Serious"... I swear all it needs is an "OUTATIME" license plate to complete the look.

Neat proof of concept for that car from I, Robot.
Very cool! "Crab steering mode" is called holonomic drive--it's commonly sought after in robotics, but is usually achieved with omnidirectional wheels.
It's a common feature in off-road forklifts and it makes life WAY easier. It's also just fun using all 3 steering modes.
The complexity of this builds are super satisfying. True talent on display here!!
I love this idea !!
3D-wheels - fantastic build. Respect.

Amazing and very ingenious build. But what’s also crazy is the undeniable importance of actual wheels. Even when you’re trying to build a wheel-less vehicle, it still requires wheels.
maybe not i think there can be a solution with magnetic just think of a motor or in german its called a ´´Drehstromasynchronmotor´´, maybe if u copy this technique and make it better u can left the wheels out. Just my thought
Just wait until we figure out how to make our cars hover I know it sounds crazy and stupid at the moment, but so was the idea of planes before they were invented by the Wright Brothers.
Dense rubber would work better, then drive wheels could be changed to rollers that taper with the ball and have a much larger contact patch. The drive rollers could also be mounted on a swing arm suspension setup, but probably not using legos.
9:35 DEJA VU I HAVE BEEN ON THIS PLACE BEFORE
amazing drifting 10/10 the most smooth drift ever in history

Pro: It's freaking awesome! TPU 3D printed spheres could remove some of the cons. Could make an awesome forklift chassis. No suspension needed then.
Awesome video. Love how you show the design process. The dust of the rollers made me think of old ball mouse and how we had to clean it.
Exactly, it is like a mouse ball just way dirtier
@@BrickTechnology you need to switch to laser drive soon :D
That would be the ultimate demolition derby! I would like it more than battle-bots.
You should control it using a 6D mouse. By tilting forward or backward you can adjust the center of rotation more to the front or more to the back. And if you shift to the left or right (instead of rotating left or right) that will enable crab mode. By tilting left or right you could even adjust the center of rotation out of the center line which could help in precise crab mode parking. But i guess you will need more motors to enable that.
I see why regular cars don’t use ball wheels. It’s a very interesting feat of engineering, but too many impracticalities for mass manufacturing
Surprised we haven't seen anyone make an insane sportscar that can drive sideways yet. Or maybe I've just missed it
