My ideal robot assistant does not have emotions, but can make sound decisions without me having to direct it much. For ex, it should know what useless things in the house can be donated or thrown away and then it actually going out to take action. My robot assistant would not be having much interaction with the kids -- it would not be a babysitter. But it would watch my kids when I need to shower and no one else is home. It doesn't even need to cook, but it needs to clean up after each time we eat meals. You know-- doing things that really just take time away from the kids.
Working moms all around the world deserve one.
