The Wine-tasting Robot
As we all know, robots are now becoming more helpful in humans daily life. This wine-tasting robot could discriminate between wine types. However, the test condition is still limited: the sensor has to touch surface of the wine and it must be clean.
The robot then will work by transmitting infrared rays at the wine and degree of absorption of certain wavelengths would be measured by the robot. According to the absorbance spectrum obtained from the wine, the robot could estimate the most components of the wine, such as sugar and fat. Then this information will send to the database it had, the database eventually will tell the robot what kind of wine it is. The robot now finishes it tasting job.
Tasting wine is not only hard for human,but also quite chanllenging for robots. This is because the differences in absorbance spectra among different types of wine are really small to differ. The cleanness of the sensor will decide the accuracy of the results.
Hence, the future development for such a robot is to improve the infrared sensor to make it with a wider spectrum that may covers the range from near-infrared rays to the mid-infrared spectrum.
