World's First SCREW-BIKE

Do you remember when I made a bicycle with an omni-wheel on the front? A while later I moved on and tried to make a bike with two omni-wheels.
As soon as I’d assembled that version I realised it would have been better to have made Mecanum wheels, which have the little wheels slanted all around them. These are typically used on the four corners of a robot so it can move in any direction, but I want to put them all in a line, so the bike still balances sideways, but can screw itself along.

[@dalmeow]

I was thinking the same thing!

[@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!

[@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.

[@SkippertheBart]

Trouble is, mecanum wheels don't bear heavy weights very well due to all the moving parts. For a forklift, it'd either only be good for light duty, or you'd need a lot of wheels. Then again, I have found some videos with mecanum wheeled forklifts, so people ARE doing it.

[@Pailzor]

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.

[@MorningMan]

[@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.

If you used an axial torsion load cell on the handlebar shaft you could control rotation by twisting the handlebars while still having stationary handlebars for stability. Maybe you could steal one out of an old X-65F joystick?

[@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)

I am amazed at the way the bike balances itself when near still or motionless and when you move either to the left or right with no forward or reverse it just looks so awesome... I mean its just absolutely solid and not making any micro movements that I can see.. It is almost like its got 4 wheels with one being in each corner... that is amazing...

[@CoffeeAndPaul]

Yes, there might be very small points in the big wheels' rotational position of natural, mechanical stoppage, points when 2 mecanums from each wheel both contact the ground at equidistant but counter-body positions, which allows the big wheel to come to "rest" on a surface, like a sort of saw-tooth gap of lateral space where the wheel best rests vertically. Or maybe he's just a great, 3-axis, spatial coder 👍👍!

[@mobbs6426]

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

[@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.

[@TheWildRobot8292]

this looks like something straight out of sci-fi! nice work!

[@doctorc-ton1099]

A warehouse forklift needs to be this maneuverable. Your bike is great! Glad I stopped by through sheer curiosity. Peace!

[@viroxd]

wow that is way more stable now, great job!

[@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.

[@computersales]

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

[@SVanHutten]

Great project and for sure great fun as well.

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.

[@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.

[@brr8888]

I can appreciate the unimaginable amount of work put into this project!

[@santanumaitra3962]

Incredibly innovative, smart and cool!

[@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.

[@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!

[@genophobia-8573]

perfect for a steady-cam filming mounted on this

[@That3th3]

Def the best bike you've built yet. If you can get it to work on softer and bumpier terrain then I'd be really excited to see bikes like this on the streets

[@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.

[@maxmoritz5065]

Thanks for the video. You deserve clicks for this . The making of this machine was a joy to watch..

[@volcon]

Absolute Legend. You rock James

[@tarmacterrorist.thepotato]

Amazing engineering! This would make parking in tight spaces so easy! Liked and subbed!

[@dwang085]

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. I think there’s probably some off the shelf options available in the controller to help manage that. It’s a very common issue with PID and often employed to improve the basic PID

[@Sven_Dongle]

Often got rid of to remove integral windup

[@sommeone]

I've been working on a set of custom mecanum wheels for the past year for my engineering capstone project and I just wanted to let you know that this video is both incredibly triggering and incredibly impressive to me. You did an amazing job! :D

[@izaakgray1718]

Encroyable. I'd be fascinated to see this in a counter-steer/lean capable bike with a punchy motor,

[@joshuaentwistle960]

This is amazing. Rotate your seating and controls 90 degrees so the screw motion is for sideways and full wheel rotation is for forwards and backwards. It'll look odd... but you could legitimately call it a moto-cross bike.

[@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)

[@weldeddaydreams]

This is brilliant. For the steering controls, you should set it up to steer as you lean, but the amoint it steers is based on how far you twist the left grip
