Swivel castor or omnidirectional wheel?

Yea, they often dont get enough friction with the ground - but for a caster, thats a good thing :P

It also depends a lot on what the caster material is made out of (plastic=low friction, rubber=high friction)

Haha this is amusing/creepy.. I was searching on google for "omni wheel castor" and I found this exact thread in one of the top hits!

Pity I didn't answer my question here ;D

Omni wheels seemed like a great idea, although when this team I was competing against used them, theirs weren't rubber, which would explain why their robot didn't move.

I will try get some rubber ones. Thanks for info.
