Omni-wheels you can buy are normally not that cheap, especially the larger ones. I’ve seen some forklift trucks with mecanum wheels which have slanted wheels around their circumference, but I’m imagining that those are fairly costly. I really want to get hold of a large omni-wheel strong enough for me to ride on, and I’ll talk more about what I’m planning to do with it at the end of the video. So for now, it looks like I have to design and build one. | James Bruton
