Seems like it would only work for objects with large, flat bottoms—if you tried to use it barefoot it would likely rip your toes off.
This is just a crude early version. Eventually the tiles will be significantly smaller, quieter, and less prone to ripping toes off.
I wonder if a layer of Ripstop over the tiles would reduce performance. I could imagine fabric being a less expensive option than R&Ding more proprietary tech like making the tiles even smaller.
Edit: Glossed over the fact the tiles rotate. Nevermind me.
A company called Virtuix already developed a treadmill like this called the Omni like 10 years ago. They have released a few home versions of it and some larger ones for arcades. They’re still refining it for mass production it seems.
Pretty sure that was basically a plastic bowl you slide around in your socks on.
