Here's next week's video, early for Patrons. This one goes out publicly on Tuesday 15th.

This is quite an interesting mechanism which I'll be doing some more work on in future videos.

Active Omni-Wheel - PREVIEW VERSION

What about if we could actively drive the smaller passive wheels around the circumference of an omni-wheel? Then we could have a robot with one omni-wheel and make it balance in both axes. I found a project called OmBURo, and I’ll a put a link to the video and details in the description. This robot does exactly what I’m looking for – it consists of one big omni-wheel with driven wheels around its circumference. This allows it to balance in both axes. The Honda U3-X is a personal mobility solution, and it also features a two-axis actively driven omni-wheel. This is larger and looks pretty robust since it can carry a human.

Great wheel project, it's got my mind wondering, what about lots of individual caterpillar tracks to drive the wheel perpendicular driven around a main wheel? You could then have a lot of surface area driving forward and left and right. I would love 4 of them on my MGF ;-).

Neil Devonshire

Ooh, the tracks could lean as well during cornering, keep the contact area on the ground when the wheel leans 🤔

That's awesome! I would imagine that patent is expiring soon? Could become a best seller toy if you could streamline the design. Obviously, I love the project choice! Nice work!

Your wheels are cylinders. Would elliptical (ellipsoidal?) wheels reduce friction? Seems like an easy test for at least the main wheel rollers and the low curvature would make printing simple enough (not much overhang). 🤷🏼‍♂️ Great video topic btw. Thx.

XRobots

I think that would mean they were less likely to contact the smaller rollers around the outside - they should probably be inverted so they have a cut-out-ellipse on their profile?

I keep trying to see it as gears rather than wheels. This thing is kind of a differential, right? Is it interesting to think about the outer wheels somehow as a helical gear?

They just had to pick a sport bike didn't they!? That's wild! Looks like those small wheels are set in pairs with a gear in the mid-axle? I still think it would be cooler as a robot. Someday, I'm going to have to build a replica of this robot from 1999: https://youtu.be/in56RYbv8Gs?t=332
