[@DouglasWalrath]

i'd change the controls to use both twist grips to control turning, twisting one twist grip turns the bike in that direction and twisting both moves the bike forward/backward depending on the direction switch, this would make it easier to steer at speed since you can just slightly let off one of the twist grips to steer

[@zanthraxnl]

That sounds a lot easier. 2 grips with 2-way control would allow for tank-like controls. Turn both the same direction for forward/backward motion and twisting in 2 separate directions controls steering. But like James said, he couldn't find grips like this. Still, doesn't sound like something he couldn't build himself.

[@vladkamael]

This is actually a smart idea! I believe this would actually be great to use + no additional significant parts/upgrades needed!

[@Drakoman07]

I was just thinking the same lol. Still using his same controls, he can mix the input of two twist grips, and just flip the switch for reverse. It would be way more intuitive as the user, but maybe not as the person trying to figure out how to implement lol

[@DouglasWalrath]

@@Drakoman07 it doesn't seem too difficult to implement, just have 2 numbers in software, one for turning that is controlled by the difference between the 2 throttles and one for forward/backward that is controlled by the sum of the throttles minus the difference between the throttles, then just mix those results into the motor throttles the same way he does currently for the movement and the balancing

[@segue2ant395]

I'd suggest this control method, but pod-racer/speeder-bike style, with two nautical throttle levers instead of twist-grips - that way you can pull back, too. Pull back on both to go backwards, or pull back on one and forward on the other for *very* sharp turns.

[@AdamLindgrenComposer]

If you can find forward and backward handles, I suggest building a VCS (Vehicle Control System) program that translates the two different handlebar actions into different effects: - both full forward: full speed ahead - one full forward, one neutral: slight forward engine power, but turn in the direction of neutral - one full forward, one full backward: full rotation in direction of full backward - one full backward, one neutral: slight backward engine power, but turn in direction of full backward - both full backward: full speed backward - both neutral: full stop This would be much more intuitive of a driving experience. Combine that with the yaw from leaning, and I think Disney will be hitting you up for on-set speederbikes!

[@eloujtimereaver4504]

Yeah, also, obvious question: why was handle rotation not implemented and used for bike rotation, you know, one of the only control mechanisms implemented in all current bikes?

[@KitaBFawkes]

Ah, there is a reason for that. Mecanum drives actually have another movement plane. They can straight up just go sideways. So how would you account for strafing with that schema?

[@eloujtimereaver4504]

@@KitaBFawkes It looks like it is currently using leaning for that. I might lean toward just using a thumbstick for that, maybe one of those little ones on flightsticks.

[@Aburaishi]

@@KitaBFawkes With this control scheme, you could maybe change the operation of the existing switches to cause them to alternate between forward-backward and left-right controls. Would be a bit bizarre to get used to (just rotate the above controls 90 degrees left, basically), but I don't see why it wouldn't work. Given that he couldn't even find forward and backward handles in the first place, though, I imagine that might be harder to implement than I'd expect; just sticking with leaning for lateral movement might be more fluid anyway

[@KitaBFawkes]

@@Aburaishi our issue with leaning is that you need to do so at speed to maintain balance. So it naturally kicks into an inward drift at speed in a turn? No, thank you. As someone familiar with mecanum drive... we recommend you think of it the same way you would a vehicle with these same wheels on 4 corners.

[@Tigery760]

I believe the original intention was to make this a speeder bike. At least he mentions it in a previous version of this build.

[@HenrikMyrhaug]

That's an amazing build! Personally, I think it might be more intuitive if turning the left handle would turn you clockwise, turning the right handle would turn you counter-clockwise, and turning both at once would make you go forward. This would allow you to rotate both ways without a reverse turning switch, so you only need one reverse switch, not two. Mathematically, the difference between left and right handle positions would represent the rotation velocity, and the minimum of the two handle rotations would represent forward velocity. Since the way I understand it, you move the robot sideways by leaning sideways, you would be able to move all directions except in reverse without having to constantly toggle switches.

Would be way too hard to go straight, having to hold two different throttles at exactly the same positions constantly.

[@benruniko]

I think it is a cool idea, but i think the difficulty with that would be unintentional input. Maybe the cells could be in the pedals and the handlebars could remain the same support point?

[@OleBrouer]

@Teiz83 Something like what you suggested has actually been done before for the joystick of the F16 (I think). But is was actually quickly reverted back to a normal joystick that actually moves because the human brain works better when it gets that feedback of the position of the hand. So I guess a similar thing could happen hear where you “forget” what input you are making and thus go on to make a wrong input (a bit like the other guy said)

For a two-way throttle, you might want to look at pallet trucks. We called them butterfly switches, but I think they're just called thumbwheels. Effectively, the handles curve around to meet near the switch which can be tilted either way with your thumb. On the smaller trucks, they're usually attached to each other so you can use your left/right hand, but on larger trucks with more controls, one might do the forward and back while the other controls the forks. Just search electric picking truck throttle control. You'll see what I'm talking about. Runntech have a header you can buy. But it looks like the important switches are attached through the middle, so it wouldn't be appropriate for this project out of the box

As far as practical application, the only drive-testing I noticed that really matters is 12:40 - 12:46, where you go forward, spin, and go backward. Most of the rest is going sideways, on sideways wheels, so of course it works. Also, it appears to go faster sideways, because of the wheel-omniwheel size difference. I'd suggest facing the full wheels forwards as usual, and it'd make a highly-maneuverable motorcycle, with comparable speeds to a regular one. That said, awesome build, and it looks like you had a lot of fun riding it around.

[@Feynt]

I was thinking, why not have twist controls for the handlebars themselves. Grip twist to go forward/reverse as it is now, but turn the handlebars like you would on a standard bike to engage rotation. Also when moving at speed, you probably want to rotate from the direction of travel rather than from the centre of balance for the bike. If the bike suddenly began turning to face the direction of travel side on, it would have to over correct for the sideways force. Turning the front faster would give you, the rider, ample time to adjust your balance. Otherwise, great stuff. Looks like fun.

I think you’re probably experiencing integral windup. A potential solution is a leaky integrator. But there are several methods to dealing with the integral windup.

Like any two wheel vehicle if there is forward speed and a turn rate occurring then allow the chassis to lean into the turn. Of course this would need to be speed and turn rate dependent. Again thx for sharing.

[@daquekenfor6901]

This is super impressive James!!! If I may make one suggestion, and that's a little guard to keep your shoes from accidentally coming in contact with the wheels. I would love to see a race around a track with 4 or 5 of these!

[@codyman242002]

Your projects get better each time.

[@duaneayers6117]

Every kid in your neighborhood should be watching u every time u come out of your garage. Because of all the kool things u build.

[@andrewb378]

Someone: *Shows James a motorcycle* James: "Screw that"

[@viroxd]

wow that is way more stable now, great job!

[@rodrigoff7456]

1:40 seizure alert! 🤣😵‍💫

[@RickTashma]

OMG, that is some *serious* engineering! Thank you, James, for taking on such an ambitious project and sharing it so openly with us. Cheers.

[@jnewmy14]

Dude amazing build, absolutely awesome. The thing that had me though was the cinematography in the parking lot scene. The way the whole video took a different feel when the camera angle and music changed had me dying laughing seeing your goofy smile lol. Nicely done!

[@futtymad]

Could you make one with smaller wheels and a shroud so it looks even more like it shouldn’t be able to balance! Brilliant as always! So much hard work! Well done and thanks for taking the time to create and share it.

[@aserta]

8:00 Protip, whenever you deal with rod ends, just pop them on first, then bolt them on to whatever you're bolting them on to, because rod ends have this bad habbit of locking the shaft in place whenever they get misaligned.

[@XoNMan1]

I agree, this IS the coolest thing you've built. It's cool to see the last 12 months or so of projects all culminate in this project which both looks really cool and works really well!

[@MorningMan]

My dude, that was incredible, amazing job! I was actually just talking with a friend about using this style of wheel on cars, as it would change the dynamics on the road significantly! The applications of this are so cool though! Keep refining this, and it will be something truly groundbreaking!

[@whitesnakefr]

The fact that you can just build this at home is why I love the industrial revolution

[@Meyer-gp7nq]

The Industrial Revolution and its consequences have been a disaster for the human race (sorry it was obligatory)

[@tophlaw4274]

another amazing build! I'm so glad this one actually works as designed 🤔though I would've liked to see at least a bit of you driving forward & back along the length of the parking lot since that's visually counter intuitive to how the wheels are oriented. 🥳that said, it's still an amazing build though I'd be curious about how fast it can go forward... cheers James & looking forward to your next creation!

[@StubbyPhillips]

Yeah, looks like it doesn't really do the forward in a straight line thing very well. Nifty idea though.

[@g.j.647]

Something like a "slalom" course would have been nice.

[@Scott_C]

" I"m James Bruton of course I'm going to 3D print an amazing mechanical semi-robotic device that amazes everyone" ...

[@celiacelisally]

***Incredible! This is my first video from you, and I am hooked. Thank you for such beautiful content! I'm not a scientist, engineer, or mechanic, so I apologize if this is a silly question. Why wasn't grease applied to the silver rod that threads between all the wheels? I thought grease or oil prevents excessive heat from friction. I'd appreciate an answer. Thank you.

[@maxwell_edison]

Not gonna lie as fun as it was to watch the constant cuts from 1:40 gave me some vertigo

[@crazylu1234]

I had to search a while for this comment. Thought I was the only one with "Schwindelgefühl" during that section. 😅

[@Linktothepast83]

I have a feeling this would work even better as a chair and not a bike, and since it's sideways motion is better than forward sit on the side and have the steering on the side as well. It would make a nice chair with a great degree of moving freedom.

[@joshuanicholson420]

Dude, stunning level of thinking, design, engineering and building. You are a legend. The possible uses of this for things like wheelchairs is amazing

[@smithheart360]

Your skill growth since the 123D days is insane and inspiring. This bike is awesome.

[@CaseyW491]

BEAUTIFUL work, all around! And on such an ambitious project, too.

[@mastasolo]

James is the Skunkworks of KZbin.

[@cho4d]

hahaha the eccentric englishman tinkering in his garage equivalent of skunkworks

[@crunchybones2528]

@cho4d shut up

[@charchar635]

I just realised this is exactly how the drones in siege work.... BRB HAVE A PROJECT IDEA

[@ParasocialCatgirl]

ooh, have fun!

[@TheWeen344]

OH SHIT NOT A BAD SHOUT

[@o1-preview]

and he never cameback ):

[@seebeedee]

Wireless Bluetooth controller on an amplifier. Lets run 20-200 at once? 🤩

[@Zelk37]

What was your idea dude, and any progress on it? 👀

[@computersales]

Crazy that 3D printed stuff is starting to look super legit. Also cool you are open sourcing the project.

[@cameroncorr7789]

Enjoy your content but your editing gives me flicker vertigo. Maybe not so many snaps back and forth with fast motion? A little is fine but too much is a turn off.

[@StuBotNYC]

Now that you said that I too can’t watch anymore

[@L33tSkE3t]

Yeah, now that you mentioned it, I don’t get vertigo or seasickness but, it was even a bit much for me too. Still incredible content though. Hope you’re not feeling unwell because of it.

[@amorphous-d8e]

Yeah that bit was kinda hurting my brain

[@Hellosirrrr]

Cry about it

[@hillbillypowpow]

​@@L33tSkE3tIf I hope they are unwell from it, does that cancel yours out?

[@MotoMotoBrain]

what about a thumb stick for rotation?

[@Laundry_Hamper]

Yee, chop a game controller in half and mount either side on the ends of the handlebars

[@seebeedee]

Laundry hamper! My brain exactly!👍😁 Dual six axis controllers.. Were invented For This! 🎮

[@Lou.B]

I ADMIRE your tenacity!!! Astonishing amount of complex work!

[@akakuzen]

9:37 AMOGUS

[@Helmut_Kohl]

AMOGUS

[@jakobkoller1479]

You could steer it like a tank with the two throttles

[@0xba5]

My thought exactly

[@seebeedee]

A Bluetooth dual six-axis controller. Already exists. Made for this!

[@danvidsgaming7789]

love this, super industrial, the headlight was a great addition. I could see something like this zipping around on a factory floor or something in some kind of dystopian sci-fi setting.

[@dielaughing73]

Or utopian..

[@vinzent1992]

As an enginerd and lover of everything two-wheeled I have to say that this is one of the most awesome things I've seen in a long time, definitely take my hat off to you. Love the headlight you put on it :'D

[@philurbaniak1811]

If the A Team was just one guy

[@philurbaniak1811]

Now build one for each foot and ride them on stilts 😃

[@elimcgamerguy]

imagine controlling it with a couple thumbsticks, console FPS style

[@zuctimil5249]

late stage capitalism hits different

[@FrancescoDondi]

Late stage? It's just getting started.

[@drew-shourd]

Amazing technology and your knowledge to put it all together is quite astounding James, it goes in soooo many directions, yet I was dying to just see it go straightforward to show a more practical application.

[@smert_rashistskiy_pederacii]

Looks good, but what happens to the wheels when they hit the asphalt?

[@chronobot2001]

This is off the scale. Pure genius.

[@marcelwood5064]

It shocks me how calm his voice can be while making literally the sickest thing I've ever seen 😍😍

[@Nhumba]

Thank you James - truly amazing!

[@Chuckiele]

Another legendary project of yours.
