58mmプラスチックオムニホイール（サーボおよびLEGO Mindstorms NXT対応）

I used four of these wheels with the Lego EV3 and 4 Large motors. The wheels allow the robot to rotate or move in any direction without turning. The wheels have good traction on a plastic folding table or laminate flooring. I would not recommend the wheels for carpet or dirt. The hub protrudes slightly so the wheels do not rub on the frame. The Lego axle fits snug so the wheels do not slide. GREAT WHEELS.

I like the idea of switching out multiple hubs. And even though they are swap-able, they are still very tough and won't spin freely. Which is great!

I really liked the mounting solution. Having interchangeable hubs makes them versatile. The wheels themselves are durable and came at a reasonable price.

Wheels are good, smooth rotation

The size is great because it is equal to LEGO wheels. Just need to say that one of the wheel was not well glue and got detached. I think I can glue it again but it makes it clear that before you put the center hub the wheel can break in the middle. I give 4 stars because this was one wheel in twenty and the price is very good.
