Automatic Litterbox Central

Would like to try this one but floor space is problematic. I had this great idea, but unfortunately I R not a engineer.

It seems like you could build a frame for this that rolls the box in place. The center of gravity would have to be about 2 feet off the ground, necessitating a couple of stairs for the cat (move out of the way to spin), and it would of course have to lock in place so it doesn't move when it's in use. But this would make it easy for older people to use, and to use in tight spots.

Has anybody, by any chance, thought of this/built one?

Don't bother.

Figuring out how to make this litterbox work (the right amount of little... how to roll it just right.... and how to put it together to avoid litter leak) is not worth it. Just use a scoop and plastic bag for poop and pee removal is just as easy... not work a penny over a paper box with a plastic bag as a liner...
