It's been wonderful seeing all the things you've managed to build with this omni-wheel! Can"t wait to see what you've got in store next. At the risk of coming off as patronizing, I'd highly recommend elbow pads, it's so easy to break an elbow falling on concrete and elbows do not heal, it just takes one bad hit and you won't ever be able to fully extend your arm or lift heavy weights with that arm again. Take it from someone who broke both.
an interesting modification (since i don't think you're offroading right?) is flipping the seat brace so it's below the chassis that way you're sitting closer to the ground and hopefully don't flip as much
And/or lower the center of mass a bit by adding a bit of mass if possible. There seems some room for some extra work (E) to compensate the added mass acceleration? Easier to try out?
@10:00 you need to add a couple stabilizer wheels on either side of the back drift wheel, to keep from turning over, which is common on Trikes... You dont need 2 drift wheels, just add 2 stabalizer ball wheels on either side of the drift wheel :-D
Maybe just a larger pair of front wheels with the mounts inverted so the cart hangs below the center motor shaft. But over all its a bit too narrow to be stable, it needs another foot in width and larger front wheels to make it more stable
If he also put some 'training wheels' on casters to either side of the big wheel at the same width as the front wheels, or wider, he should be good. That thing looks like it'd be super fun.

I just want to test out the things you make. Just so cool. Could you ever make an omniwheel for a walker and/or cane? The front wheels on walkers are normally casters, but terrible ones, and something like this would make navigating much easier. And having a wheel on a cane or walking stick is a great options for those going through rehabilitation and just need a point of reference for balance.
Amazing! 2 spinning casters mounted on either side of the omni wheel about an inch from the ground could give you a safety and prevent tipping. cant wait to see what you make next!
I'd suggest having a sloped wedge for your left foot. Perhaps have a button on the left and right of the wedge, so when you pivot your ankle left and right, you can switch between reverse and forwards. Also perhaps some stabiliser bars on the left and right with castor wheels? (Like people put on Reliant Robins)
Wow!!! Looks soo cool. Its so fun watching you build cool stuff with irregular things like omni-wheels, as well as mixing steel, ply and 3d printed parts!
James dress this up a bit like a vintage bumper car, put some caster wheels under the back corners for stability (hidden by the dress up body work) and it would be a sellable product! It's wicked! Well done!
I think this would work really well if you turned the omniwheel 90 degrees so that it points in the direction you are going and make it the driving wheel, removing the front wheel drive and then adding some resistance to the tiny wheels on the omni so they don't spin as easily but only under load. That way it's RWD but can still skid sideways with the tiny wheels and you won't need the extra "drift buttons" at the steering wheel! I think it would drive really well as long as you adjust the resistance of the tiny wheels so that you don't spin out instantly but can also skid some.
How about two smaller omni wheels on the rear but instead of powering them they have a brake so you can release the brake to control how much you drift
Every project I have seen on this channel has been a wonder of innovation and imagination. I hope you refine this one. If the seat was mounted on a slider that moved it to the side of the direction the cart was turning as well as tilted the driver that would help with the problem of rollover. I would work the design up from pivoting the driver and steering column together left to right, loosing the accelerator pedal for twist grips on the steering handle and just having blocks the driver can brace their feet on.
MAN!!! This, but a giant BB8 sphere wheel on the back. I've been wanting to comment that idea for a while but didn't want to write a whole thing about it. But yeah, please put a sphere wheel on the back of this setup. Thank you for your content.
Amazing project... lots of fun! With two rear omni-wheels it would make it more stable, yes... but it would lose the quirky cool three-wheel look. Maybe if you make the chassis a little longer and put the seat as close to the floor as possible... it would be less cheating on cheating! hahah
Hey James, where do you get all of your amazing ideas from? Having the idea for an Omni Drift wheel. Do you spent time on engineering forums or do they come from your expert knowledge in robotics?
Watching you cut those bars with the super high rpm chopsaw is terrifying. A horizontal bandsaw has made my life easier and retired my metal cutting disc.
I'm wondering how much of the stability is just your high CG.. Most 'drift trikes' have the riders rear just about running on the ground. But it's an impressive concept!
Awesome engineering James. I would love to see you take an EGO zero turn riding mower and convert it to 4 wheel steering using the existing lap bars. Basically converting the front caster wheels to steer along with the lap bars position. Maybe add a windshield wiper motor to each caster fork spindle. Main issue with zero turn mowers is the front caster wheels are not part of the lap bar steering, so they suck on slopes.
There needs to be a cart race with things like this. Where engineers can build wacky carts like this and compete. The cart has to have something different than a typical driving system and maybe has a limited maximum speed for safety purposes.
The front wheels skid allot, I think the Ackermann angle is wrong when drifting. considering it is only going to be "drifting" to turn then it is probably worth using a zero or negative Ackermann angle. Also, you need to mix the wheel speeds to account for the turning otherwise it will try to skid like a fixed axle drive.
AntiAckermann would work for typical drifting, no grip under the rear axle with front guiding wheels, but would not work for this due to the setup. The problem is, you have a perpendicularly driven omni-wheel that only allows for two axes of movement, forward passively and horizontally actively, which means it does not have a turning circle itself; mixed with the front wheels, it does have a turning circle somewhere, but the center will be in-line with the center of the kart. Mix this with the more typical front axle's steering, and you'll get a turning circle somewhere between the two, due to stupid amounts of skid and slip; and I can almost guarantee you that James has not gone down that rabbit hole to figure out where the turning circle's center actually is throughout the entire steering throw or how to optimize the mixing to maximize efficiency during turning, either normally or drifting. Honestly, this is a bad design, and designs like this will always be bad, because they do not work for the purpose they're made to do. The rear wheel should be based on an active omni-wheel, the kind where both axes of motion on a singular wheel are powered, except this should be inversed to where instead of powering these axes they should instead be passive and braked, that way one axis can be locked out to passively allow full movement to the other axis, vice versa, and variable mixing. But even with this, the best you'll achieve is poor emulation of actual drifting, it'd better emulate fwd drifting (also known as ass-dragging) but even then it'd poorly do it; this is because in actual drifting you'll actually have a ton of energy in the rear wheels and the fact that there is still some grip, this is what causes rear ends to sway to one side under burnouts and drifting has similar characteristics, whereas in any omni-wheel setup the rear wheels will be dead and passive or poorly driven, the various dynamics are just not there. Overall, it's a characteristics issue, and omni-wheels just cannot replicate these characteristics while attempting to emulate drifting. This is also just poor use of omni-wheels anyways, they're meant to allow for omni-directional movement under proper mixing of multiple axles (parallel or non-parallel) with omni-wheels on each axle, not give weird handling characteristics to a hybrid setup; they're meant for a movement platform, not a typical vehicle. The bike was a better concept, though it should've had the omni-wheel in the back, that way you can use your hips to swing it from side to side, similar to the swing bikes Swing King produces.
@@NegussugeN Oh look, a logical fallacy. Honestly, get out of here with that shit. Have enough logical thought and comprehension to understand what I've described goes far beyond if I've made my own omni-wheel or not. Fun fact, you don't even have to construct your own wheel to understand how they work, especially when they're already in abundant supply at certain scales, and the scale disparity really doesn't change my argument at all, which further invalidates your fallacy. If you had any comprehension skills, you'd understand that I clearly have a deeper understanding of what's going on here than the vast majority of the other comments, do you see anyone else talking about the actual dynamics of drifting and why those dynamics do not mate the dynamics of this build, or explaining why these kind of faux-drifting vehicles do not work as intended? So kindly, piss off with your logical fallacies, and learn how to contribute to a conversation, and while you're at it learn some basic comprehension and logical thought, and learn how to have intelligent arguments. But congratulations at being entirely unintelligent within a forum that otherwise should be intelligent conversation; but here we are, with your idiocy, and someone having to explain why you're an idiot. Honestly, go back to Twitter if logical fallacies are your best counterargument. In case you don't get it, building something similar is entirely irrelevant when we're discussing the math and physics behind it, and building something similar with no accounting for improvements doesn't actually move the conversation along, you can better refine a design on-paper before having a physical variant anyways, so you also clearly don't understand anything about the processes of design or production. I also do have credentials that go far beyond just making an omni-wheel, but again they're irrelevant outside the fact that I do understand physics and the dynamics of various systems, so honestly just stop with the logical fallacy bullshit. And to further expose your ignorance, if you're talking about the kart build, that's an omni-wheel _vehicle,_ and an omni-_wheel_ itself. A literal toddler could tell you the difference between a wheel and a vehicle. If you also had any basic comprehension skills, you'd also notice that I have an issue with omni-wheel _vehicles_ themselves as their dynamics and characteristics just don't make sense, as omni-wheels are better for _omni-directional platforms,_ as that's the intended use of omni-wheels. It's so easy to not be an idiot, I suggest you try it sometime.
Very crazy looking thing - I love it!😍 Stability could be much better by just lovering seat into frame and then move feet in front of front wheels, so whole body would be closer to the ground 🤓 Really cool steering wheel, smart to use 3d print and cheap of the shelf thumb throttles. Super idea 🤯👌
you could also have a couple of passive wheels on the back like training wheels to help prevent tipping. love this! it looks like it's a blast to ride!
I find it much easier to control the TIG torch by holding it palm up and to rest my elbow holding the torch on the table/frame/my leg or something stable. It is kind of like holding a drum stick traditional style. I tend to get straighter more consistent weld beads compared to palm down the way you seem to be welding. I think a lot of the stability comes from being able to rest my elbow on something stable, so I can pivot the torch around my elbow. Once I am ready to weld the bead, I do one test pass without turning on the TIG and just make sure I can reach the entire weld, or at least make a good length bead on longer welds.
I think that if you actually made it so that the rear wheel won't let you flip the cart (regulator), then it would be actually very fun and much more usable.
The stability issue is due to the weight balance. Your weight is mostly on the single rear wheel so the front wheels are under-loaded and contributing less to the lateral stability of the vehicle.If you wanted to keep it as a trike you could either extend the rear back farther, or move the front wheels back. Or move the seat forward I guess but that would mean a major redesign...
The next obvious step is to reverse the steering linkage, and add a potentiometer to the steering shaft for drifting. When you turn right, the front wheels should turn left and the rear omniwheel should start to drift you right. Take the human element right out of it. You'll need some speed data too I suppose so the omniwheel only turns at an appropriate rate for your forward speed.
Looks like it must be extremely interesting to drive. It might also have been interesting to drive the back wheel through a PID controller with lateral acceleration as its main input. That way you could have a pedal controlling how loose the rear end is, instead of switches on the steering wheel. Just a though.
I feel like if you were to lower the seat all the way down to to floor it’ll lower the centre of mass enough for you to be much more stable with the one rear wheel! Great build
You should totally add regenerative braking to the rear wheel and make it a free spinning wheel so that when you're drifting without powering it you're recharging the batteries
maybe with 2 omnidirectional wheels on the back for stability you could avoid capsizing, like helper wheels for bikes but the kind that's used for office chairs and follow the direction of movement
My biggest recommendation would be getting a pair of wrist protectors. That way when you tip over you don't get hurt using your hands to catch yourself!
Why on earth did you make the CoG so high? If you flipped the seat mount bars 180 and we'll it underneath you could drop the seat height massively. Put a 360 knuckle joint in the steering column and you would have a much lower CoG with out having to put a forth wheel in. Also I noticed that the drift wheel is quite jerky, you could code in an Euler function to smooth out the throttle off jerks
Imagine making a life sized Mario cart with this system?? Get like 5-10 carts and yourtubers to all race with an implemented drift and boost system would be awesome…this is amazing btw
Two angle controlled caster wheels at the rear may also be interesting. With some combination of throttle input and steering angle, simulate breaking traction by turning the casters. Maybe if I start now I can have something ready before my nephews are old enough to get their actual drivers licenses... some 12-ish years should be enough :o Though this was of course an exercise in omni-wheel applications, and a very cool one at that!
As it has many more freedom, one of the modes could be drift cart simulation, where you only turn steering wheel and it would influence rear wheel turn speed to get a drift cart effect. Cool.
I would’ve personally made the rear wheel controlled by two separate pedals for both feet, something similar to rudder pedals on a plane. Then you can put a throttle on the wheel, maybe like a brake lever on a bicycle? Very cool however, awesome work
have you thought about using 2 omni wheels for power, and have the longboard wheels sideways, would be hard to use but would drift without effort... and continue to drift despite attempts stopping
Interesting as a concept but for fun it needs 2 backs wheels and a lower CoG so you can go nuts without stability worries. I think I'd stick to an over powered motor and spinning wheels thou --- there is just something about doing something it isn't "designed" to do (wheels going sideways) which makes it fun.
Where did you get that freaky seat?! Love it! Three wheelers are normally a bit tippy, just make sure that the end with the higher center of gravity is the end with two wheels. Looks like a fun ride. Kudos
You could add 2 helper wheels on the corners in the back to avoid tipping over I think. Link to the Amazon accelerator pedal please? I find it cool that there is no brake pedal.

Your weight is mostly on the single rear wheel so the front wheels are under-loaded and contributing less to the lateral stability of the vehicle.If you wanted to keep it as a trike you could either extend the rear back farther, or move the front wheels back. Or move the seat forward I guess but that would mean a major redesign...
The next obvious step is to reverse the steering linkage, and add a potentiometer to the steering shaft for drifting. When you turn right, the front wheels should turn left and the rear omniwheel should start to drift you right. Take the human element right out of it. You'll need some speed data too I suppose so the omniwheel only turns at an appropriate rate for your forward speed.
Looks like it must be extremely interesting to drive. It might also have been interesting to drive the back wheel through a PID controller with lateral acceleration as its main input. That way you could have a pedal controlling how loose the rear end is, instead of switches on the steering wheel. Just a though.
Bloody excellent.
I feel like if you were to lower the seat all the way down to to floor it’ll lower the centre of mass enough for you to be much more stable with the one rear wheel! Great build
You should totally add regenerative braking to the rear wheel and make it a free spinning wheel so that when you're drifting without powering it you're recharging the batteries
maybe with 2 omnidirectional wheels on the back for stability you could avoid capsizing, like helper wheels for bikes but the kind that's used for office chairs and follow the direction of movement
That's some serious progress, you made a functioning vehicle! I think maybe next you should focus on stability.
My biggest recommendation would be getting a pair of wrist protectors. That way when you tip over you don't get hurt using your hands to catch yourself!
Why on earth did you make the CoG so high? If you flipped the seat mount bars 180 and we'll it underneath you could drop the seat height massively. Put a 360 knuckle joint in the steering column and you would have a much lower CoG with out having to put a forth wheel in. Also I noticed that the drift wheel is quite jerky, you could code in an Euler function to smooth out the throttle off jerks
Seems like a really good platform for a battle bot!
As a practical matter, isn't an omniwheel functionally similar to a caster?
Love it! Great job!!
Nice onboard video on this one!
This looks such a fun thing to play around !
Imagine making a life sized Mario cart with this system?? Get like 5-10 carts and yourtubers to all race with an implemented drift and boost system would be awesome…this is amazing btw
You should make a cart with the ball wheels I love to see that
I'd say you were crabbing, either way it looks pretty nuts!
Maybe you could make a Ripstik style robot, using the back and forth motion of a tilted cast wheel to generate forward momentum.
Two angle controlled caster wheels at the rear may also be interesting. With some combination of throttle input and steering angle, simulate breaking traction by turning the casters. Maybe if I start now I can have something ready before my nephews are old enough to get their actual drivers licenses... some 12-ish years should be enough :o
Though this was of course an exercise in omni-wheel applications, and a very cool one at that!
You should pass the easiest doctorate you can find so you can call yourself Dr. James Bruton.
Kinda has a nice ring to it.
Holly crap! You need to commercialize this!
As it has many more freedom, one of the modes could be drift cart simulation, where you only turn steering wheel and it would influence rear wheel turn speed to get a drift cart effect. Cool.
Jump Jacks next?
JK, well done! Cool project.
I would’ve personally made the rear wheel controlled by two separate pedals for both feet, something similar to rudder pedals on a plane. Then you can put a throttle on the wheel, maybe like a brake lever on a bicycle?
Very cool however, awesome work
Looks like it could use some optimization in the algorithm. Fun build!
have you thought about using 2 omni wheels for power, and have the longboard wheels sideways, would be hard to use but would drift without effort... and continue to drift despite attempts stopping
There was a great deal on that evolution chopsaw at Screwfix recently could still be there
Legend!
When he originally said drift kart I thought the back wheel would be driven and it look like a reverse trike but this is so cool
Looks like fun! Maybe add a fake pedal on the left side for you to brace that foot against better, and for those rare umbles, some elbow pads ;)
"Turn right to go left! Turn right to go left!"
Interesting as a concept but for fun it needs 2 backs wheels and a lower CoG so you can go nuts without stability worries.
I think I'd stick to an over powered motor and spinning wheels thou --- there is just something about doing something it isn't "designed" to do (wheels going sideways) which makes it fun.
for the 3D printing stuff can you tell use the infill
Add a couple of coaster wheels for stability, and drop your C of G. Should be possible to make it impossible to tip.
Where did you get that freaky seat?! Love it!
Three wheelers are normally a bit tippy, just make sure that the end with the higher center of gravity is the end with two wheels.
Looks like a fun ride. Kudos
This is probably a production ready idea.. Some company should make it and put them in a kids park.. It will be awesome..
Perhaps a pair of rear coaster wheels would help stop the cart from flipping!
You could add 2 helper wheels on the corners in the back to avoid tipping over I think. Link to the Amazon accelerator pedal please? I find it cool that there is no brake pedal.
You could also use the wheel as an auto-balancer with an IMU, like in your bike, and the kart should be a lot more stable
