Admin: Where to buy this omniwheel? and other questi about omniwheels

[airman00]

Where did u buy this omniwheel admin?

Kornylak has the cheapest at $2.69


I would need to put two of these on a threaded rod to provide 360 degree support , right?




Thanks in advance,
Eric

I'm not Admin, but I can answer your question... yes, you would need two of those to make an Omni-wheel (as shown in the attachment)

these omniwheels are costing more than my servos!!!!     


Do you guys think a ball caster would work well too?



Also, would I only need one of these to provide 360 degree support??( i plan to use only one as a caster)

Use some sort of ball, depending on the "terrain"?

[airman00]

yes but would only one of these wheels work as a caster, only one?
Please reply ASAP I need to buy the parts tomorow


Only one of these???

So I didnt actually buy that orange omni-wheel . . . my friend asked me to hold on to her robot like 5 years ago, but she quit robotics and forgot I still had her robot . . .

So I scrapped it for parts

Im so evil sometimes . . . just google around for omni-wheels, you will find some . . .

Anyway, Ive also tried ball castors but I dont like them - they have horrible ground clearance. For example, a 1" diameter ball will give you a .35" ground clearance.
