韩国采购需求：步进电机、电机轮、步进驱动器、机器人轮、机器人电机、AMR 直流电机

I'm currently working on a robot development project and have some inquiries regarding one of your mecanum wheels. Specifically, I'm interested in the product's precision levels and the methods used to determine these figures. Understanding the metrics behind this would be really helpful for our design process. Additionally, I'd like to gather information on the noise levels produced by the wheel during operation. This is crucial for us as we aim to create a smooth user experience. Any details you can provide would be greatly appreciated! Looking forward to your response.
