3. The great invention of the 20th century
with the ringing of the New Year bell in 2001, people have stepped into the 21st century with solid steps. Standing at the threshold of the turn of the century, looking back on the past and looking forward to the future, we are full of emotions and thoughts.
in the 20th century, mankind has made brilliant achievements, from the establishment of quantum theory and relativity, the application of atomic energy, the emergence of DNA double helix structure, to the rapid development of information technology, and the sketching of human genome work, Profound changes have taken place in world science and technology. Major breakthroughs have been made in information technology, biotechnology, new material technology, advanced manufacturing technology, marine technology and aerospace technology, which have greatly improved social proctivity
as one of the greatest inventions of mankind in the 20th century, robot technology has made great progress after 40 years of development since it came out in the early 1960s. After the birth growth maturity period, instrial robots have become indispensable core equipment in the manufacturing instry. There are about 750000 instrial robots in the world fighting side by side with workers on all fronts. As a rising star of the robot family, special robots have the potential to catch up because of their wide range of applications. Humanoid robots, agricultural robots, service robots, underwater robots, medical robots, military robots, entertainment robots and other special robots for various purposes have come out one after another, and are moving towards practicality at a fast speed
people often ask why robots should be developed? We say that the emergence and rapid development of robots is the inevitable result of social and economic development, in order to improve the proction level of society and the quality of human life, and let robots do the jobs that people can't and can't do well for people. In real life, some jobs will cause harm to human body, such as painting, heavy handling, etc; Some jobs require high quality, so it is difficult for people to be competent for a long time, such as automobile welding, precision assembly, etc; Some workers can't be on the scene, such as volcano exploration, deep sea exploration, space exploration, etc; Some jobs are not suitable for people to do, such as some bad environment, some boring repetitive work, etc; These are all places where robots can show off. The service robot can also provide you with health care, cleaning and security; Underwater robots can help salvage sunken ships and lay cables; Engineering robots can go up the mountain to the ground, open holes and build roads; Agricultural robots can cultivate, plant and fertilize; Military robots can attack the enemy, clear mines and discharge bombs...
nowadays, there are many puzzles about robots in the society. Some people think that robots are omnipotent. These friends know robots from movies, TV and novels. In their eyes, robots are all powerful machines. When they see real robots, they will think that robots are too ordinary to be called robots. Some people think that a robot is a human, and its shape must be like a human. How can it be called a robot if it is not like a human? However, in reality, most robots are not like a human, which makes many robot lovers disappointed. Some people think that if robots work, workers will be laid off. They regard robots as competitors. They did not expect that robots would do many useful things for people, promote the development of instry, and create more employment opportunities for human beings
definition of robot
in the scientific and technological circles, scientists will give a clear definition of every scientific and technological term, but robots have been around for decades, and there are still different opinions on the definition of robots. One of the reasons is that robots are still developing, with new models and new functions emerging. The fundamental reason is that robot is related to the concept of human, which has become a difficult philosophical question to answer. Just as the word "robot" was first born in science fiction, people are full of fantasy about robots. Perhaps it is because of the fuzzy definition of robot that people can fully imagine and create space
robot command
in fact, it's not that people don't want to give a complete definition of robot. Since the birth of robot, people have been trying to explain what is robot. But with the rapid development of robot technology and the arrival of information age, the content of robot is more and more abundant, and the definition of robot is constantly enriched and innovated
in 1886, the French writer lill Adam named the human like machine "Android" in his novel the future Eve. It consists of four parts:
1, life system (balance, walking, voice, body swing, feeling, expression, regulating movement, etc.); 2
2, modeling and quality resolving (metal covering body with free movement of joints, a kind of armor)
3, artificial muscle (there are various forms of body such as body, vein and gender on the above armor)
4, artificial skin (including skin color, mechanism, contour, hair, vision, teeth, claws, etc.)
in 1920, Czech writer Karel kapek published the science fiction play "the omnipotent robot of rosam". In the script, kapek wrote the Czech word "Robota" as "robot", which means slave. The drama foreshadows the tragic impact of the development of robots on human society, which has aroused widespread concern and is regarded as the origin of the word robot. In the play, the robot works silently according to the command of its owner, without feeling and emotion, and undertakes heavy work in a rigid way. Later, the success of rosam company made robots have feelings, which led to the rapid increase of robot application departments. In factories and housework, robots have become indispensable members. The robot found that human beings were very selfish and unfair, and finally rebelled. The robot's physical ability and intelligence were excellent, so it eliminated human beings
but robots don't know how to make themselves and think that they will be extinct soon, so they begin to search for human survivors, but with no results. Finally, a pair of male and female robots with better perception ability than other robots fell in love. At this time, robots evolved into human beings, and the world came back to life
kapek proposed the problems of robot safety, perception and self reproction. The progress of science and technology is likely to cause problems that human beings do not want. Although the science fiction world is only an imagination, human society may face this reality< In order to prevent robots from harming human beings, science fiction writer Asimov put forward "three principles of robots" in 1940:
1. Robots should not harm human beings
2. The robot should obey the human's command, except the first one
3. Robots should be able to protect themselves, except those in conflict with the first article
this is the ethical program given to robots. These three principles have been regarded as the criteria of robot development by robotics academia< At the first robotics conference held in Japan in 1967, two representative definitions were put forward. First, Mori Zhenghong and Hetian Zhouping put forward that "robot is a flexible machine with seven characteristics of mobility, indiviality, intelligence, versatility, semi mechanical and semi human nature, automaticity and Slavism". Starting from this definition, Mori proposed to represent the image of robot with 10 characteristics, such as automaticity, intelligence, indiviality, semi mechanical and semi human nature, operability, universality, informability, flexibility, finiteness and mobility. The other is a robot with the following three conditions proposed by Ichiro Kato:
1, an indivial with brain, hand and foot
2, with non-contact sensor (receiving remote information with eyes and ears) and contact sensor
3, a sensor with balance sense and intrinsic sense
etiquette robot
this definition emphasizes the meaning that robot should imitate human, that is, it works by hand, moves by foot, and completes the role of unified command by brain. The non-contact sensor and the contact sensor are equivalent to human's five sense organs, which enable the robot to recognize the external environment. The sense of balance and inherent sense are indispensable sensors for the robot to perceive its own state. This is not an instrial robot, but an autonomous robot
the definition of robot is various, the reason is that it has certain fuzziness. Animals generally have these elements, so when we understand robots as humanoid machines, we can also broadly understand robots as animal like machines< In 1988, espio of France defined robot as "robotics refers to the design of a pre planned operating system based on sensor information, and the use of this system as the research object"< In 1987, the international organization for standardization defined instrial robot: "instrial robot is a kind of programmable operating machine with automatic control operation and movement function, which can complete all kinds of work."
the definition of robot by Chinese scientists is: "robot is a kind of automatic machine. The difference is that this kind of machine has some intelligent abilities similar to human or biology, such as perception ability, planning ability, action ability and cooperation ability. It is an automatic machine with high flexibility.". In the process of researching and developing robots working in unknown and uncertain environment, people graally realize that the essence of robot technology is the combination of perception, decision-making, action and interaction technology. With the deepening of people's understanding of the intelligent nature of robot technology, robot technology began to penetrate into various fields of human activities. Combined with the application characteristics of these fields, people have developed a variety of special robots and intelligent machines with the ability of perception, decision-making, action and interaction, such as mobile robots, micro robots, underwater robots, medical robots, military robots, aerial space robots, entertainment robots, etc. The adaptability to different tasks and special environments is also an important difference between robots and general automation equipment. The appearance of these robots is far away from the shape of the original humanoid robots and instrial robots. They are more in line with the special requirements of different application fields, and their functions and intelligence are greatly enhanced, thus opening up a broader development space for robot technology< Song Jian, President of the Chinese Academy of engineering, pointed out: "the progress and application of robotics is the most convincing achievement of automatic control in the 20th century, and it is the highest automation in the contemporary sense.". Robot technology integrates the development achievements of many disciplines and represents the development frontier of high technology. Its continuous expansion in the application field of human life is causing a new understanding of the role and influence of robot technology in the world
classification of robots
there is no unified international standard on how to classify robots. Some robots are classified according to load weight, some according to control mode, some according to degree of freedom, some according to structure, and some according to application field. The general classification method is shown in the table:

4. It's supposed to be the owner of the robot who shut down the other groups
5. In fact, a robot is a machine device that performs work automatically. It can not only accept the command of human beings, but also run pre programmed programs, and act according to the principles and programs formulated by artificial intelligence technology. Its task is to assist or replace human work, such as the proction instry, construction instry, or dangerous work
it can be said that it is the proct of advanced integrated cybernetics, mechatronics, computers, materials and bionics. At present, it has important applications in instry, medicine, agriculture and even military fields
European and American countries believe that robots should be controlled by computers and have versatile automatic machines that can be changed through programming, but Japan disagrees with this view. The Japanese believe that "robots are any advanced automatic machines", which includes those manipulators that need to be operated by one person. Therefore, many Japanese robots are not defined by European and American people
at present, the concept of robot in the world has graally reached consensus. Generally speaking, people can accept that a robot is a kind of machine that realizes various functions by its own power and control ability. The United Nations Organization for standardization has adopted the definition of robot given by American robotics Association: "a programmable and multifunctional manipulator used to carry materials, parts and tools; Or special systems with changeable and programmable actions to perform different tasks. "
the evaluation criteria of robot ability include: intelligence, which refers to sensation and perception, including memory, operation, comparison, identification, judgment, decision-making, learning and logical reasoning, etc; Function refers to versatility, universality or space occupancy; Physical energy, refers to force, speed, continuous operation ability, reliability, coupling, service life, etc. Therefore, it can be said that the robot is a three-dimensional coordinate machine with biological functions.

Advantages 1. Cost saving the rise of labor cost is undoubtedly an important factor to promote the replacement of machines in various instries. Robots instead of manual proction can save more and more high labor cost
Second, it is convenient to supervise the proction process of traditional enterprises.
although there are many rules and regulations in the proction process of traditional enterprises, the employees will not thoroughly implement them in the process of implementation, so it is difficult to eliminate the phenomenon of employees' laziness, and it is difficult for enterprises to guarantee the daily proction capacity for a long time. The use of instrial robots, a large number of manual rection, enterprise personnel management is more simple and efficient
disadvantages: the robot lacks the ability of emergency response, unless the emergency can be predicted and a response plan has been set in the system, it can not deal with the emergency well. At the same time, safety measures are also needed to ensure that the robot will not harm the operator and the machine (equipment) working with him
According to the application environment, robots are divided into two categories: instrial robots and special robots This is consistent with the international classification. Instrial robot is a kind of multi joint manipulator or multi degree of freedom robot for instrial field. Special robots are all kinds of advanced robots which are used in non manufacturing instry and serve human beings besides instrial robotsincluding: service robot, underwater robot, entertainment robot, military robot, agricultural robot, etc
7. The 39 day test is of certain significance. As long as you don't have major immune deficiency or major surgery in the near future. Then the test results after two weeks are credible
it is recommended to have a selective reexamination, I believe it is still Yin!

8. If the test is negative in 39 days, you can check again in two weeks. Now the window period is two months
9. Hello! Some network management software binds the MAC address of the network card on the network workstation with the IP address of the machine. When the network card is replaced, the workstation must register again in the network management software. For convenience, just modify the registered MAC address in the
windows of the workstation.
windows of the workstation.
10. Modifying MAC address is only used under special circumstances
for example, Yantai Tietong now implements MAC address and ADSL account binding. If you dial with another machine, you will be prompted that your password is wrong, but there is no problem. At this time, you need to modify the Mac. Only by changing the MAC of the current network card to the MAC of your original network card can you use it normally
most MAC modifications are for the same reason.
