Nano Robot Structure (Schematic)
Nano-robots are based on molecular biology principles for the design of prototypes, design and manufacture of "functional molecular devices" that can operate on the nano-space, also known as molecular robots; and the development of nano-robots has become the forefront of modern technology.
At present, many countries have formulated relevant strategies or plans and invested heavily to seize the strategic high ground of this new technology of nanobots. "The Robot Times" magazine recently pointed out that the potential use of nano-robots is very wide, and it is particularly important to apply them to medical and military fields.

Medical nano robot
In the American sci-fi blockbuster “Amazing Qiqiâ€, scientists injected smaller people and spacecraft into the human body, allowing these narrow “visitors†to directly observe the organization and operation of various human organs. However, in reality, scientists have developed a variety of nanobots that can enter the human body based on the principles of molecular pathology and are expected to be used to maintain human health.
Medical nanobots are still in the experimental stage and are as large as a few millimeters long and as small as a few microns in diameter. However, it is certain that nanobots will bring about a medical revolution in the next few years.
Many engineers, scientists, and doctors believe that medical nanobots have unlimited potential - and most likely include: treating atherosclerosis, fighting cancer, removing blood clots, cleaning wounds, helping clotting, removing parasites, treating gout , Crushing kidney stones, artificial insemination, and activating cell energy make people not only stay healthy, but also prolong life.

In May 2010, scientists at Columbia University in the United States successfully developed a nano-spider robot made up of DNA molecules that can freely walk, move, turn, and stop following the DNA's trajectory, and they can be free. Walk on the surface of a two-dimensional object. This nano-spider robot is only 4 nanometers long (a nanometer is one billionth of a meter) and is smaller than one hundred thousandth of the diameter of a human hair.
Although the previous nanobots also implemented walking functions, they did not exceed 3 steps. The nano spider robot can travel 100 nanometers, equivalent to 50 steps. Scientists are programmed to move along specific orbits; the strength of this progress is that once programmed, the nano-spider robot can automate tasks without the need for human intervention. They believe that the nano-spider robot can be used in the medical industry to help humans identify and kill cancer cells for the purpose of treating cancer. It can also help people complete surgical procedures and clear up arterial blood vessels.

Scientists have developed a production line for this robot. With the advent of this kind of robot, scientists have taken a big step toward creating an advanced device that can walk through blood vessels to kill cancer cells.
Israeli scientists are currently developing a miniature nano robot that can “patrol†the human body and automatically release the medicine it carries after locking the lesion. The principle of this technique is to define a specific disease as the "yes" state during the programming process. During "patrol," the robot performs a series of calculations to check for disease indicators on messenger RNA (mRNA) at the location. If all indicators of a particular disease are met, the robot will then make a judgment that the drug should be released. If the detected indicator is not sufficient, it will eventually be in the "No" state.
Scientists have continuously improved this robot and made breakthroughs. It can now detect disease indicators from multiple sources, such as mRNA, microRNAs, proteins, and many small molecules.
The goal of the scientists is to create a large number of these nanobots in the future, allowing them to patrol the body automatically and continuously, looking for signs of various diseases. Diagnosis can be more accurate because disease indicators can be directly probed from multiple sources.
After more and better calculations, this robot can also release the first round of preventive drugs to the location where the disease is found, as the first line of defense against infection. Although the technology is still far away from us in reality, the idea of ​​being alert to physical health at all times is still very attractive.

Military Nano Robot
In the 21st century, the development of science and technology is in full swing, and military reforms are surging. Looking at the new historical starting point, what technology can, like nuclear weapons, have a revolutionary impact on the future military? Recently, foreign military experts have predicted that nano-robots are not far away from our battlefield. They will not only lead a truly revolutionary war in the world, but will also advance fundamental changes in the concepts and methods of combat.
At present, all major military powers are actively engaged in research and development of military nano-robots, and have successfully developed dozens of components for nano-robots; the nano-robots will be ready to go in some laboratories or production lines.
How does a nanobot defeat or defeat the enemy's power? First of all, the application of nano-robots to traditional weapon technology equipment will improve the tactical and technical performance of traditional weapons and equipment by improving its manufacturing materials, production processes, accusation systems, guidance systems, transportation and storage methods, and strengthen traditional methods of warfare. Killing effectiveness; secondly, develop new methods of human combat and combat methods, such as the development of nano-micro components that can block human faces, nose, mouth, and eyes, or nano-micro components that can stick to hands and feet, etc.; again, The existing chemistry and organisms transform or develop new types of chemicals or organisms and inject them into artificial or hybrid insects to spread these destructive chemicals or organisms to the bodies of hostile countries and civilians through insects. In the middle, finally, after entering the enemy's body, the nanobots can rapidly spread in the enemy camp through self-replication or self-propagation.

Relevant experts believe that military nanobots can serve as reconnaissance tools, such as "smart sand" or "smart dust." These tools have the function of an electronic nose, which is only as large as sand grains. It can analyze the surrounding environment, identify the chemical composition, and report to the monitoring system. The final reconnaissance report is very comprehensive. The data of thousands of electronic noses is combed. The reconnaissance range of each nano-electronic nose is only 1 meter. However, many electronic noses cover a limited area. These nanometer points have High reconnaissance accuracy.
If there is a variety of sensors in the network of “smart sands,†the supervisory calculator can use data fusion to form more complex and accurate real-time reconnaissance images on distant battlefields or mountain roads. The enemy is completely unaware of the local residents’ The risk is also small.
The US Department of Defense Advanced Research Projects Agency (DARPA) and the industry are developing a military nano robot that can fly. This nano-robot has only insect size or bird size; it is not easily found, it is lethal, cheap, it can react quickly, it can continue to fight, and it has good maneuverability. They plan to create a bird-sized nano-robot that can detect weapons of mass destruction by 2015 and an insect-sized nano-robot that can detect weapons of mass destruction by 2030.
Incidentally, as commissioned by DARPA, AV company developed a nano-hummingbird robot for reconnaissance in July 2011. It is equipped with many nano-scale components; this robot was named 2011 by "Time" magazine. One of the 50 best inventions of the year.

Every new technology appears to contain unlimited possibilities. It won't be long before the magical nanobots, which are only molecular in size, will continue to enter human daily life. Professor Zhou Haizhong, a well-known Chinese scholar, predicted in his 1990 article on Robots that by the middle of the 21st century, nanobots will revolutionize human labor and lifestyle.
Finally, it is worth mentioning that futurologists believe that by the second half of the 21st century, it will become meaningless to distinguish people from computers absolutely and clearly. On the one hand, humans will have a biological brain that has been greatly expanded by nano-robot technology; on the other hand, people will have a purely abiological brain, which is a replica of the human brain with greatly enhanced functions. Undoubtedly, with the improved brain, we will create numerous newer technologies that fuse with nano-robot technology. By then, humanity will enter a new world and become an authentic "new human."
