Other than robotic systems, what could possibly be of reliable use for the average person?
My porch lights turn themselves on at dusk, and back on at dawn, independent of the time of year.
My garage door closes itself if I've left it open for too long.
My vegetable garden is watered only when it needs it.
The cat's litterbox cleans itself, discards the waste into the toilet, and automatically flushes.
Next up is to have my pool keep itself filled, and notify me when I need to add Chlorine/Acid.
You just have to stop and think about what you are doing around your house that a machine can easily do. That's how people invented things like automatic sprinklers, washing machines, dishwashers, etc.
