Everyone loves the beer-fetching Willow Garage PR2 robot, as seen in a recent gallery of its greatest achievements. Evidently, it even loves itself. When developers at Bosch Research gave it a pen, it drew a handsome self-portrait.
If you're a bachelor and want a mate who does not talk back and supports your decision to have a tipple once in a while, then the P2 robot would fit the bill perfectly - although you will not be able to enjoy the more feminine aspect of a relationship.
