  • Spent a lot of time with engineers, but am not one myself. Most grinding discs and things that wear stuff down have a surface made to rip in, and higher opposed friction. Think sandpaper, it digs into a surface with those hills from the grit, and uses the friction to then drag through cutting the surface and removing material.

    With this floor, it looks like the wheels are smooth, so all though there’s some friction, it isn’t a cutting action. There’s also the fact that their friction is unopposed and can actually move the person, so the energy gets converted into movement, not the cutting force that would grind things down.

    They really are just tiny treadmills, the only reason they’re discs is so they can be tilted to change the direction the “treadmill” is going to push you. If the disc is tilted to the right, the left most edge is going forward, if the disk is tilted to the left, that right edge is moving backwards. Otherwise exact same principle as a treadmill of creating friction to move the object on it.

    Hope that helps some. Diagrams would probably help more.
