After a two-year effort researchers at NEC System Technologies and Mie University in Japan have created a robot that can taste - an electromechanical wine steward able to identify dozens of different wines, cheeses and hors d'oeuvres. When objects are placed before a sensor at the end of the robot's left arm it fires off a beam of infrared light. The reflected light is then analyzed in real time to determine the object's chemical composition. When it has identified a wine, the robot speaks up in a childlike voice. It names the brand and adds a comment or two on the taste, such as whether it is a buttery chardonnay or a full-bodied shiraz, and what kind of foods might go well on the side. Nice trick, but wines are very similar in their spectral fingerprints. The variations are very subtle. Some of the mistakes made would get a human sommelier fired. When a reporter's hand was placed against the robot's taste sensor, it was identified as prosciutto. A cameraman was mistaken for bacon.
