Robotics

The robot belongs to a branch of technology, which involves mechanical, electronic, computing and artificial intelligence. Currently, the robot is found in systems consisting of automatic machines and mechanical parts, can be controlled manually or automatically by electrical circuits. Although these machines are made and mechanisms, sometimes we can say that they are "alive", but nothing more than a simple robot. The robots are increasingly used by humans to do their jobs. And in future, the robots can control everything. The robots do not dream, do not feel, nor tire, because they are only machines. Today, due to reduced costs of robots, this technology is highly required by factories and industries, because they contribute positively to the increase of production.

The Robot in Society:

In our society a great need to perform tasks with efficiency and precision, and there are also tasks in places where human presence is difficult, risky and sometimes impossible, for example: at the bottom of the sea or in space. And instead of humans, robots are used, not at risk of life, to achieve these tasks.

There are robots in several areas in today's society:

Robots disarming of bombs.

Robots in science education and the study

Robots workers

There are different types of robots:

Intelligent

Control computer


Learning


Manipulators



Impacts on society:

With the development of robots, will appear many social impacts, but the most problem is unemployment. In factories, to be achieved greater productivity and quality in products, more economic, computers and robots are recruited guided by a need for survival in the market. But the workers, they are terrified, because a robot replaces sometimes tens or even hundreds of men in the production line.

Isaac Asimov, American writer of science fiction, set the 4 laws of robotics:

1st: A robot may not injure a human being and not by default, allow any evil to happen.

2nd: A robot must obey the orders of humans, except when they contradict the First Law.


3rd: A robot must protect its integrity, provided that, with this, not in the First and Second Laws.

4th: "A robot may not cause or allow evil to humanity that it does."
