This is just a bad take. It literally is a hollow inflatable already.

I'm surprised they didn't just design some magnetic roller system to couple the ball to the ramp and stop it if necessary. It really would have cost less than this person's compensation, most likely.

A handful of small metal balls inside it and a magnet at its holding spot is all it would need id imagine

I was thinking this too. Four captive rollers in a magnetic frame on the inside of the ball, and a moving electromagnet below the floor to guide it.
