If I could have a robot do anything it would be a robot that you can have conversations with about your day, partner, work and life in general. It would be non-intimidating and very curious, asking unique questions which would be analyzed behind the scenes. Based upon the information captured in conversation, the robot would be able to suggest activities you should do, foods you should eat and people you should see to keep you as happy and healthy as possible. If it could integrate in with your shopping lists, calendar events and to-do lists it would be a truly great user experience and helpful tool.
