Uses for each kind of Wheels

Regular Wheels

Regular wheels are good wheels for light robots that do not have to turn quickly. Regular wheels tend to skid when turning in place. They are best used with one set of Omni wheels on the front.

Omni Wheels

Omni wheels are great for heavy robots. Omni wheels do not skid while turning and put less strain on the motors. When used on a light robot they become hard to control as opposed to on a heavy robot where they will be more sluggish.

Mecanum Wheels

Mecanum wheels have no particular use other than to be able to drive sideways.
