On the first page of the repair manual for my Yamaha back in 1975 it advised that:
"Repair of Yamaha motorcycle require great piece of mind".
Advice that has held me in good staid for tackling any job since.
I suspect it's where Robert M. Pirsig got his inspiration from !

Pirsig's book is not actually about motorcycle maintenance. Which was a disappointment because I was much into motorcycles at the time. Not sure it's even about Zen much. Also a disappointment.
It was hugely famous back then so I tried reading it. Didn't get the idea and gave up half way through. Seemed like some ramblings of a lunatic.
Perhaps I should try again.

Pardon me, but what is a “mecanum wheel”?

Haha, nice find. Have you used anything like that? I feel it would get hung up a lot on anything but a smooth surface.

Very true. I see a lot of "ball casters" used on robots large and small. But as our good forum friend and author the late Gordon McComb pointed out numerous times, these are designed to run upright, per the image. Only in this orientation (borientation, Toby) do the small internal balls actually roll and recirculate. When you invert it to use as a caster, all the balls fall away and there's massive internal friction and often the big ball just skids along instead of rolling. For many surfaces, you might as just glue or weld the big steel ball on and let it slide, essentially a larger radius version of this cap nut "mecanum wheel".

But the way, if we are going with a traditional erco all wood bot, you could just glue on a real nut.
