That sounds pretty darn cool, creative idea. 
I was looking for a different post about robots and stumbled on this one which I had forgotten.
I have to say that the idea wasn't as original as they may thinks as in the Andre Norton novel Galactic Derelict (1959 part of her Time Traders series) the ship i question travels automatically to a ancient refueling base and a snake robot hose auto attaches to refuel the ship. So the idea has been out there for decades before being created in real life.
