I think it would be really cool to have a docking station for the rover so that you could just auto navigate back home when you are on a far venture out .
You could auto pilot back to the dock and it would just be the rover that you have to consider. Maybe making it as big as a full wagon train? but the rover is the reason it docks.
Knowing nothing about development, I would think you already have a system in place considering the drones do this already, but you'd need the user to be able to trigger the autopilot on command or interupt it.
