Our construction method, using a dual roller design, allows for a constant contact patch with a narrow profile. Each roller is tailored for the individual wheel diameter, and provides the correct, constant radius. We don't share rollers between wheel types -- these wheels aren't "almost round" they're actually round. This smooth-ride provides higher efficiency and reduces wasted power!
Omni-Directional wheel assembly hardware is separate from sprocket mounting hardware. Sprockets are screwed into captive standoffs. This allows for easy removal and replacement of sprockets without disassembling the entire wheel. No more worrying about your whole wheel falling apart just because you wanted to remove the sprocket.

Mounting Hardware Guide. If you want to use omnis to move sideways, you could mount them in a holonomic configuration like this:.
You need to put one or one set per side. To go sideways, run the ones on the front and back sides. They allow you to turn about the center of your drive wheels. DO NOT try to power them, because they do not operate well in that manner. There are some issues with them, such as a certain level of finesse needed in the coding of the robot and each wheel needs individual power in order for them to operate properly.
They also do not do well when one of the wheels is lifted off the ground. You may also want to look into using a gyro to maintain a certain orientation of the robot as well.
The AndyMark omni wheels have a 1. I can find you teams that would say otherwise. I just posted the image for reference. How do you get them to move sideways?
