Perhaps instead of rails you could go for a flying quadcopter-drone with some sort of manipulator arm. If it was light it could even land and charge from the same ports it uses to communicate with appliances.
Of course if any big FAANG-company does this expect it to be beaming everything it sees straight up to the cloud. Amazon already tried this with their Ring security drone.
