To post the postcard, I'd need a stamp. Why not put a picture of the Queen's head on the top panel and call it Giant Postage Stamp (GPS for short ). The proportions seem about right for it.
And looks like it drives quite nicely too. With wheels that close together, the robot can have a tendency to veer off when trying to drive in a straight line, but it looks pretty controllable in that video.
