A friend who is the RF coordinator on the tour sent me THIS LINK. This is very cool technology. It's nice to have a big budget.

On the previous Bon Jovi tour, they used similar robots for cameras, with a twist - the robots were suspended upside down from an overhead track. They could move independently on the track until they reached a proximity limit (due to rigging load).
The way the tour split up the local crew calls I don't know what other robotics were used, if any, but the dual use show in the clip (video & set architecture) is pretty slick. Thanks for the link.
