Alternating sex with the fridge and the trash can. Yeah, that is the way to go. Will it also make popcorn?
Programmed to obey the Three Laws?
Mickeys house had a conveyor thing. He typed on a console what he wanted and it came down the conveyor.
Before it was over Mickey was on it, trying to manually stop it.
All because he wanted change his order.
Why have a smart phone play music and take pictures, when a camera and a music player already exist?
Yeah, but R2 can offer a seat. Plus, I figure tripod wheels would make it easier to get up and down stairs (but that’s what the R&D is for)
Those dog robots were in Trump’s recent parade.
I suspect that android sex will be seen as mainly something losers do, like a guy who masturbates to AI-generated porn or only ever has sex with hookers.
Because those are all things that go in your pocket, and by making them one device, it takes up less pocket space. But there’s plenty of room in your home.
Advertising?
For much of the year, our neighbors are away in foreign parts, and our only neighbor is the robot that cuts the lawn (controlled by smartphone). I expect this will be true of quite a few people in the decades to come; living next door to a robot.
That reminds me of the Ray Bradbury short story, There Will Come Soft Rains.
From Wikipedia
A nuclear catastrophe leaves the city of Allendale, California, entirely desolate. However, within one miraculously preserved house, the daily routine continues – automatic systems within the home prepare breakfast, clean the house, make beds, wash dishes, and address the former residents without any knowledge of their current state as burnt silhouettes on one of the walls, similar to Human Shadow Etched in Stone.
My luck I’d get Karen the HOA robot as a neighbor. 
An R2D2-shaped unit that cannot climb stairs is only going to be able to reach about 20% of my house at best.
I just turned in a column for a special issue of a computer design journal about putting machine learning into IoT devices like these. That includes voice. So, it is coming. (No, not that meaning.)
A story from Galaxy from 1972 had a vacuum cleaner that did walls as well as floors, and learned how to open the front door to go to the house next door where it tried to hump the smart sewing machine there. So maybe we should limit what these machines can do.
See?! This is the kind of adaptive technology that I was talking about in the OP.
Of course you can add a popcorn maker attachment.
In the future, I predict that AI porn will start with animating some girl’s Instagram photo. Talk about creepy.
For some reason I thought that this was something it would be able to do. Yeah, climbing stairs is going to be required.
Make Popcorn?
Come on. You can’t walk to the microwave?
That dang robot needs to be scrubbing the oven and changing the oil in my car(or whatever fluid goes in my Jetsons-type flying car).
I prefer this video.
Well, I sure am glad you weren’t in the room when the television remote control was being pitched!
The House Droid would also have a receptacle for a plug. Need to plug something in? Call your droid over, and plug that bad boy in. No more looking for a wall outlet.
And it would have a flashlight. Because who can’t use a beam of light?
it could also dispense your pet their treats. Like these things.
Cats wound take naps on it. Dogs would follow it around.
The possibilities are endless!
Painting toenails would be handy. 
Future? The technology exists for that now.
I agree that the technology exists now. I’m saying it’s going to be a thing people will routinely do. Just give it a few years.
I predict that it won’t be long before porn is completely customizable AI. And if you can “create” the person (or people) you want to see, and then direct them in their performance, then it’s a short jump to just selecting photos of actual people.
The end goal of AI image generation is to be able to duplicate anything one can imagine.
