I built a more whimsical version of this - my daughter and I basically built a 'junk robot' from a 1980s movie, told it 'you're an independent and free junk robot living in a yard', and let it go: https://www.chrisfenton.com/meet-grasso-the-yard-robot/

I did this like 18 months ago, so it uses a webcam + multimodal LLM to figure out what it's looking at, it has a motor in its base to let it look back and forth, and it use a python wrapper around another LLM as its 'brain'. It worked pretty well!
