I saw it in Manchester and it is the later. I believe there is a static system build in the stage that tells the rock where to go and is driven by a motor that is in the rock.
I believe every major theatre has this static position system build into their stages. I am very vague on how this works, if anyone knows anymore it would be cool if they like to elaborated, I would be interested to find out how this system works.
