So that’s what they’re called!
Simply amazing.

One word: Moonwalk!

my bad, looks like he has some.

My FIRST robotics team had these on our robot my senior year. I was the driver; it was FUN. ;) my favorite part about them is that the forward bias of mecanum wheels makes them great for driving forward efficiently but you still had the freedom to pretend you were drifting around corners lol

I really need to get a 3D printer. Cheap, useful parts, made right in my home workshop, would be amazing.

I’ve been thinking about building one for a while, but, parts for the printer itself are still expensive.

Are mecanum wheels patented or something like that?

My FIRST team used mecanums this year. They were very effective and we loved how they allowed movement in any direction. We have 2 demo videos on the website. Check them out.

Looks cool and lord knows making these wheels is a quite a task. However, and not to take away from what’s been done, the rollers on mecanum wheels take a lot of lateral stress. I have my doubts that the printable material is tough enough to take it. Perhaps if the weight is kept to an absolute minimum (chasis, battery, motors, electronics < 1 kilo), you might get by for a while.
