And AI in a robot body? Not in CP2020, maaybe in 2077. What's more likely is an AI using a robot body (or more than just one) as a drone. And as for AIs taking up a heap of resources, even in 2020 they mention several rogue AIs that have sent out their 'programming' in clumps of code strewn around the Net, or even duplicating themselves. So maybe they could have a small section of their 'code' controlling a robot body as a drone. Could look fully human if they're available by 2077.
And lets face it, just replace the sloppy organic bits (ie the brain) from a Gemini FCC, and add in a computer additional 'memory' space, and you'd have your human looking 'robot'.
As for 'dumb' bots? Again, I can totally see that. Even having humanoid 'bots what can go down to the corner store to get you some 'fo-milk' that you forgot to get on the way home so you can have it on your kibble breakfast cereal. Have a read of Robopocalypse for some other ideas. And that's set in around 2040 from memory.
