New York, July 29 - Japanese scientists have developed a robotic wine taster, which they claim can correctly identify the unique organic components of 30 popular wines within 30 seconds.<br><br>The robot called Wine-bot was developed by engineers from the NEC System Technologies laboratory and Mie University, both in Japan. It is about twice the size of a three-litre wine box and consists of a microcomputer and an optical sensing instrument, reported the online edition of New Scientist.<br><br>Currently, fraud detection is performed through human tasting and careful analysis of a vineyard's records. Retailers and customs officials have been looking for a new machine that could identify wine fraud, speed up detection processes and reduce costs.<br><br>The new machine developed by the scientists can even tell where the wine came from, the report said.<br><br>For analysis, a five-millilitre sample of wine is poured into a tray in front of the machine. Light-emitting diodes then fire infrared light at the sample and the reflected light is sensed by an array of photodiodes. <br><br>By identifying the wavelengths of infrared light that have been absorbed by the sample, the wine-bot is capable of distinguishing between 30 different varieties or blends of grape correctly within 30 seconds. <br><br>The company promises to extend the number of wines the device can recognise before it is commercialised.<br><br>
