I wonder why the word "robotic" is there. Would it be only robots that could manage this?

I'm not sure how confining a device to the surface of a sphere simulates curved space. Maybe you can explain it to me.

I'm sorry, but I saw/heard no mention of which laws of physics were defied. The small deviations in the average position of the framework could easily be due to very slight differences in the individual motors, the rails they rode on, the controlling software, the motor drivers, etc.

Without reading your referred URL, sounds like it would have to use some variation of spherical geometry, and I think that is different whether you are inside or outside the sphere. Plus the sphere has a variable radius--gives me a headache!

"Plus the sphere has a variable radius--gives me a headache!"

Please elaborate!

In my world, if the radius isn't the same everywhere, at any given instant, then it isn't a sphere. If you refer to a sphere that is changing size over time, then the path of any object moving in a given direction along that surface is NOT a circular arc, as it would be on a static spherical surface.

I suspect we're saying the same thing, but you are using more precise language. The radius of the space curvature would depend on the amount of mass and the distance from that mass.
