Robots provided with autonomous operation capabilities and, particularly, those sporting sense organs similar to the human ones, have always tickled the fancy of science fiction writers and screenwriters.
As always happens, from a certain point in history, even official science has started to deal with the subject, at first with the so-called “strong theses”, whose objective was to reproduce, to substitute, the capabilities that are typical of humans.
Once the dimensions and the problems connected to the theme had been understood, the researches oriented themselves towards more practical objectives, and that could allow technically feasible solutions to be thought of. Currently, a variety of applications has been created, finding wide use in many industrial and service sectors.
For what regards reading barcodes, technology went from the laser scan of a simple sequence of black and white vertical bars, to the interpretation of those that are known as QR Codes (Quick Response Code) by means of a video camera.
Other applications that are widely spread can be found in firms processing or packaging food, and in the gathering of agricultural products, or in the automotive and electronic production.
