1.Icebreaker: Setting aside all technical limits, what is the one primary function you would want your household robot to perform? Please be as specific as possible.

I have no idea now. Welp,managing all grocery shopping and meal prep from start to finish is quite appealing. If the robot can wash bowls and dishes automatically, that would be great.

And I wonder how to make money with this robot...

Then excellent human cooks may be popular. You can make money with it：）
