Circumvent driving on the littlewheel in software, and then you don't need that complexity. Embed a small magnet instead at the end of the axle, and you can sense it on top when it aprroaches, and then change the rotation of the robot. No disadvantage for a mapping application.

The worry that I hold is, when all of this technology is developed into mass market platforms manual driving would likely become illegal. Strafing is impractical to a forward facing pilot in a crowded situation. Unless, that is, the pilot wasn't human and could consider multiple directions at once. If these sideways maneuvers are available human error would skyrocket unless every vehicle, not just the ones which strafe, are autonomous and communicating with eachother.

Also the ‘strafing’ could be regulated in a couple ways: only being available at extremely slow speeds mainly for parking, or being mostly inactive until the driver turns it on manually. There are other potential pros besides strafing as well like reducing slip, improving cornering, torque vectoring/traction control and nullifying other less safe maneuvers like u-turns and j-turns. I think with these things in mind and considering the current safety measures (blind spot sensors/alerts, collision prevention, cameras, etc.) we could make it work without too much danger, and still allow for human operation.

So far this would make a cool chair base, with motors though... a *REALY* cool chair base. Train it to automatically turn when you approach, or zip across the room when it sees you getting ready to sit in the air.

I wonder if the GoodYear concept would work better with an attached underpiece that prevents the wheel from falling out even with the magnetic forces. And I do see the problem with braking, as there is considerably less contact between the wheels and the surface. Furthermore, although this is just speculation on my behalf, I feel that fishtailing would be a problem, as the wheels (unlike cylindrical wheels) do not favour forward movement above the other axes. (And oversteer/understeer would probably be a problem too). Overall, without being an engineer or anything, I feel like ball wheels are definitely more suited for slower vehicles, where maneuverability is more important than handling and braking is not a major concern, like utility robots

Perhaps for a future revision, instead of having little wheels in the bottom of the assembly, have ball bearings or perhaps the balls they had in old computer mice, to allow everything to glide smoothly. Your videos are truly inspiring and I look forward to them every week, Thank you!

It looks realy greate. You can add additional wheels in gap similar one that you have on sides to minimize that bumping effect and as well to gain a bit of space and make wheels more rigid.

@coderentity2079

3 жыл бұрын

A mecanum wheel track in the gap (beads at 45 degrees on a D shaped tank track) would solve it, but it's complex and looses the main advantage of this wheel design: it can go offroad. Bumps are inevitable there.

First, congrats for your video, very concise and informative, and the basis for many mechanical and robotic applications. At 5:33 and 6:58, I don't know if another commenter pointed out, but you should try a ball at the top of each hemisphere, coupled to a ring ball bearing, and a screw-on retaining ring; that would make the wheel even more smooth as the ball could freely rotate in any direction and make an even smoother profile into a complete sphere. I'll try to work in a Blender model if you find it useful for a follow up video. Again, excellent video.

Very cool! Have you considered replacing the small white wheel with ball casters? You wouldn't need to worry about the aligning the axis of rotation. Plus, it would limit the gap between the larger ball and ball caster.

Please make a video on CAD models, (Fusion) it would be great for us!

I said the other day it was a spherical ball when you shown us the image! (Disclaimer: My comment may not be 100% accurate)

I can't speak for ball shaped wheels, but one of the biggest problems with omni or mecanum wheels is that you lose a lot of traction and can get pushed around easily, so if a car is going around a curve at speed, they will lose control much more easily than if they had used normal wheels.

Definitely wondering how you would control this. can't wait to see more!

Seems like a lot more parts to manufacture and assemble than a modern wheel, as well as being excessively complex for something like a modern automobile - which is plenty complex as-is. Great video exploring the concept :)

Very nice design and well presented. Thank you for sharing. In my opinion the wheels era has to come to an end. I have been working on levitation type design. I have some success and still spending little time in my lab to further power enhancement. Little success but it is moving in good direction. You can imagine what would be the world like if we get rid of wheels and aerodynamic technology. I am doing my part, a very small contribution but it is in process. Anyway, thank you for your wonderful design. It is sensational to think about cars moving on a ball-wheels.

This was quite nice, but you teased us with the dream car with magnet driven spheres. That's what we'd like to see next. A 3/4 size model should do nicely. ;)

Looks good well done. On a 4 wheel robot i could see an issue if you stopped on the "little wheel" amd wanted to move off at 90 degrees as in the car parking demo at the start. I guess that would have to have a little radius on the turn baked in to the controller.

When a concept technology provokes a deep gut laugh it may just be worth looking into XD

It's quite simple in concept but maybe not so in implementation but I think we need to do this. The wheel ball housing and wheel ball housing act as stator and rotor with 360 degree range of torque actuation. Minimal mass so efficient and minimal components with a high safety factor. Extreme acceleration torque is possible. This is genius. Brilliant concept.
