I Want To Make A Robot Which W

I want to make a robot which will help me do smart grocery shopping. I am throwing away so many things from the fridge and something is always missing from it... It will be so nice to have someone who learns what you eat and in which quantities, knows your schedule and makes you recommendation based on all this info on what do buy. Someone you can talk to about all these boring problems and doesn't mind that, who actually listens and gives you a very accurate advice, suggests interesting personalized cooking ideas and warns you when it recognizes the chocolate wrapping. You cannot get angry on a robot and even if you do, he doesn't mind...
