Domino's Will Start Delivering Pizza with a Driverless Robot

So far, it seems like this new "pizza robot" is only being introduced in New Zealand. According to a Facebook post by Domino's, the new delivery system, that they call DRU, isn't out in full force but it's getting there:

DRU has a passion for delivering piping hot meals and a nice warm smile to customers. While he won't be taking to the streets tomorrow, he is enjoying his early progress as a prototype and giving customers a glimpse into the future of what is possible.

This idea seems very similar to an April Fools day campaign that Domino's UK ran last year. Could that be what started this project?
