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.

@DouglasWalrath 14 днів тому

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 14 днів тому

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 14 днів тому

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

@Drakoman07 14 днів тому

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 14 днів тому

@@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 14 днів тому

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.

@CoffeeAndPaul 5 днів тому

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 👍👍!

@AdamLindgrenComposer 20 годин тому

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!

@HenrikMyrhaug 12 днів тому

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.

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

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.

he literally explained the issue with having standard handlebars that rotate....IN THE VIDEO.

@@samdillard1824 I thought I heard him say handlebars that TILT with the frame were problematic, not ROTATE while fixed vertically.

It would be dual each side, expensive and from scratch? No, you need a dual six axis game controller. Exactly what you need here. 👍

This is amazing. I 3D-printed my own small mecanum wheel car with heat shrink tubing as tyres for more grip. But a bike in real size, that's two levels ahead.

Love the video - i see a possible application for this tech to improve on the mobility scooter market. We have all seen an elderly person struggle to make a 3 point turn with one of those things.

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!

Excited to see if theres any more testing footage of you going forwards over a long distance. A lot of the footage is within a jazz square or small circle. Cool stuff so far

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.

@pathmada 7 днів тому

i must say that is very impressive watching you lean side to side and try to make it tip and it just stays straight upright always

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!

@doctorc-ton1099 8 днів тому

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

@That3th3 6 днів тому

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

@tophlaw4274 14 днів тому

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 14 днів тому

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

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 14 днів тому

@NicleT 8 днів тому

This is absolutely amazing! You made it!! An observation: In your outdoor tests, we can see that when the terrain is not even, a wheel might not touching the ground and this can affect your direction. Maybe each four wheels could have some sort of shock absorbers to reduce those gaps? But, hey! What you did here is already a fantastic achievement. Bravo!!

@weldeddaydreams 14 днів тому

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

@futtymad 14 днів тому

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.
