Robot instead of tongue
Robots replace the person in professional work of
a various kind more and more. Now they attempt already and on such
traditionally human profession, as the taster. Brazilian inventor
Antonio Riul from city of San Carlos has thought up the robot replacing
human language. New robot-language, according to its parent, promises
to give exact and reliable parameters of taste, it is simple in circulation
and can be widely used by the companies which now trust professionals-tasters
in definition of taste and quality of the new products, such, as a
wine, tea, coffee, mineral water etc.
Up to some time the robot can not replace
the people - tasters fault in check of such thin products, as high
quality wines and whisky. Well-known, nevertheless, that tasters in
due course "are satiated", and their taste loses a subtlety.
Robot-language, however, can is successful compete to human receptors,
you see it never tire from "tasty" work.
Under the application of inventors, robot-language
can define even hardly perceptible impurity in water to determine
a difference between kaberne one year from different vineyards and
even to distinguish a wine of one grade from one vineyard, but different
years. Electronic language can catch and molecules of sugar or salt
in the concentration inaccessible to human receptors.
The robot is based on the same principle, as human
language: it has receptors of definition of four kinds of tastes -
salty, sweet, bitter and sour. These chemical receptors at it are
submitted by four most thin films under an electric voltage. At definition
of taste each film absorbs a liquid substance, differently changing
force of a current in an electric circuit. Various tasting shades
are displayed then on the special diagram. Any interested person can
find more full description of the device in magazine Nature
