The etymological origin of the word robotic is found, neither more nor less, than in the Czech. Specifically, in the union of two terms: robota which can be defined as "forced labor" and in rabota which is synonymous with "servitude." In the same way, it should be stressed that the first time that more or less reference is made to it was in the year 1920 in the work of the writer Karel Capek entitled “The Rossum Universal Robots”.
The robotics is the science and the technique which is involved in the design, manufacture and use of robots . A robot is, on the other hand, a machine that can be programmed to interact with objects and make it mimic, in a certain way, human or animal behavior.
The computing , the electronics , the mechanics and the engineering They are just some of the disciplines that combine in robotics. The main objective of robotics is the construction of devices that work automatically and perform difficult or impossible work for human beings.
Currently, robotics has evolved by leaps and bounds and has led to the development of a series of disciplines such as robotic surgery. In this case, it has as a clear objective to improve the health of the human being and for this it carries out a series of very complex surgical interventions that require great precision. Thus, by means of robots it is possible to eliminate the dangers that are brought about by those that are undertaken by human hands.
In this way, we must highlight, for example, the existence of a robot called Da Vinci that has become one of the pillars of the aforementioned surgery. It is a device through which operations as important as those of transoral surgery have been successfully carried out.
Likewise, robotics has also managed to create robots that are useful to assist and help all those who encounter some kind of physical disability. And that without forgetting the set of robots that are being designed in the military field to, for example, carry out rescue operations.
The writer Isaac Asimov (1920 -1992 ) is usually considered responsible for the concept of robotics. This author, specialized in science fiction works and scientific dissemination, proposed Three Laws of Robotics , a kind of regulation that regulates the actions of the robots of his fiction books but that, if a similar degree of technological development is achieved, could be applied in the future reality. These rules are printed as mathematical formulas in the "Positronic paths" of the robot's memory.
The First Law of Robotics points out that a robot should not harm a person or let a person suffer damage due to their lack of action. The Second law states that a robot must comply with all the orders dictated by a human, with the exception that occurs if these orders were contradictory with respect to the First Law . The Third Law establishes that a robot must take care of its own integrity, except when this protection causes an inconvenience with the First wave Second law .
