Place wheels in normal positions , omni wheels slide right and left easier when a robot turns. If you want to be snazzy they are great for three wheel projects too. The bot will roll forward even if the two driving wheels are at an angle of up to 45 degrees

Thanx Jstarne1:)

So there they just attach to the modified servos like standard wheels?
No need for a fancy script, or anything?
