I wonder if that soccer ball droid is going to become the "new" sidekick of the new characters kind of like R2 was for the OT characters (and PT characters, I guess). Or, could it simply be a short lived gag moment like Chewbecca scaring away the mouse droid on the Death Star?

I highly doubt that it will be a throwaway gag, as this trailer shows most major players in the movie. I would bet money that this is Daisy Ridley's droid, on some sort of mission at the station.

That's what I'm guessing since Ridley's character is shown racing towards the station the same droid is at (or so it seems).
