It's basically like giving an Alexa, Siri, or Gemini a body. It moves, show "emotions", comments when someone enter the room, uses the camera to see who entered the room and comment on that, make comments when my 3D printer finishes, things like that.
I can also turn on lights, the TV, the AC, ask about the weather, and other basic assistant stuff, ofc.
So basically you're using it as an AI mother in law, nice.
