Naturally, Lu Li would not study genetic weapons.
As for whether others will study... Guess?
The successful compilation of the human gene map further enhanced Lu Li's academic reputation. In the field of genetics, it has become a recognized academic authority worldwide.
The International Nobel Prize Judging Committee also had to announce that Lu Li was nominated for the Nobel Prize in Medicine and entered the Nobel Prize Jury.
Conquering cancer, conquering AIDS, completing the human genetic map, each item is enough to win the Nobel Prize. If this cannot be won, there is no need for the Nobel Prize.
The success of the human genetic map not only gave Lu Li a huge academic reputation, but also a group of graduate students such as Wen Wan.
This is a great achievement destined to be recorded in history. Wen Wan and others participated in this project, and their names also go down in history.
In addition, this achievement also allowed Wen Wanmei and others to gain a huge academic reputation and academic qualifications.
This answer sheet is enough for their graduate studies to graduate successfully.
Wen Wanmei and others have also received work invitations from various research institutions across the country and even the world.
It's just... no one wants to leave.
The fool will leave. "Lu Li's student", what a dazzling golden sign is this?
Sister Wen Wan and others immediately applied to Lu Li to continue enrolling in Lu Li's doctoral students.
Lu Li didn't have any comments on Sister Wen Wan and others applying to continue their Ph. In the area of ​​genetics, there is still a lot of research that can be done. It is naturally appropriate to have these students who are familiar with them as helpers.
As a result, Sister Wen Wan and others continued to study in Lu Li's laboratory as doctoral students.
"Genetic engineering, this is a project with broad applications."
Lu Li called sister Wen Wan and others to arrange a new research project with them, "We have completed the human genetic map. In this process, everyone has made a lot of contributions and learned a lot."
"Now, I will point you to a few new research directions."
Lu Li stretched his finger to the projection screen and opened the screen. Pictures of chickens, ducks, cows and sheep, rice, wheat, corn, potatoes, and even kelp and sea fish appeared on the screen.
"As we all know, our country is a country with a large population. There are 1.4 billion people living in our land. Food, for us, is never too much."
Holding the laser pointer and pointing to the picture on the projection screen, Lu Li continued: "We have completed the human genetic map. On this basis, we can also compile genetic maps of various crops, livestock, fishery and aquatic products, and then Make gene editing and modification to further improve yield and quality."
"teacher!"
At this time, Sister Wen Wan suddenly raised her hand.
"What's the problem?" Lu Li glanced at the Wen Wan sister.
"Teacher, your task with us is to study the genes of crops and do gene editing?"
Sister Wen Wan had some doubts on her face, "But...the crops after gene editing are not genetically modified foods?"
"You are right, it is indeed genetically modified."
Lu Li smiled and nodded, "But... is there any problem with genetic modification? This kind of genetic modification of crops and livestock, this kind of genetic modification work, has been doing since ancient times!"
"Fruit tree grafting, hybrid rice, crossbreeding of livestock... etc., these are all genetic modifications, all of which can be considered genetically modified."
"All the current crops, all the fruit trees, all the poultry and livestock have undergone countless genetic modifications and countless variety improvements. Seedless watermelon, purple sweet potato, apple pear, strictly speaking, these are all It is a genetically modified product."
"The genetic modification technology itself is not problematic. What is problematic is that the genetic modification technology does not pass, or the operation is improper, leading to hidden dangers in the products after gene editing."
In this regard, Lu Li naturally has the most say.
Genetically modified technology, itself is no problem. However, some people abused this technology for some commercial purposes, and some products with serious hidden dangers appeared.
This has led to "talking about genetically modified discoloration" in society, and people are very resistant to genetically modified products.
For any kind of new technology, it is wrong to abuse and resist. It is necessary to treat the problem scientifically and dialectically.
"Next, I will point you to a research direction."
Lu Li didn't talk much about "genetically modified technology" either. The laser pointer pointed at the seaweed in the picture.
"Seaweed, these are aquatic plants all over the ocean. Large seaweed, more than fifty meters long."
Lu Li turned his head to look at the students below, and smiled, "Think about it, if we use gene editing technology to modify the nutrient storage mechanism of seaweed, so that they can produce nutrient-rich tuberous rhizomes like potatoes and sweet potatoes, or Fruits one after another. Then...the vast ocean will become a new fertile field!"
"Students, this is a work of great significance! Gene technology will definitely change the world!"
As soon as the voice fell, there was a burst of warm applause below.
Sister Wen Wan and others, all of them were full of excitement and excitement.
This is changing the world!
Under the leadership of the teacher, we are changing the world!
The genetic era has arrived!
...
After taking a class with Sister Wen Wan and others, and after pointing out the future research direction, Lu Li left the genetic laboratory.
Crops, poultry and livestock, melons and fruits, and even marine aquatic products and freshwater aquatic products can actually be genetically studied.
Gene editing, variety improvement, and even marine farming all have broad research prospects.
It's just that... In this kind of research, there is too much trivial work to do, and countless hours are spent repetitively and constantly testing the effects of various genetic modifications.
Of course, this kind of trivial work must be done by the students. As a mentor, isn't it enough to point out the direction and do some technical checks?
More importantly, Lu Li still has his own project to do!
Robotics has completed the research on the reducer, and now there is one servo motor left for research.
Servo motors are mainly used to drive the joints of the robot and belong to the power part of the drive unit.
The servo motor used in the robot system requires high precision, high reliability, high heat capacity, high strength, high response speed, and also requires light weight and miniaturization.
Simply put, it is small in size, light in weight, strong in power, and high in accuracy.
At present, there are huge bottlenecks in domestic servo motors.
Even if the high-precision laser processing technology developed by Lu Li can solve the problem of processing accuracy, in the servo motor technology, there is still a lack of a key technology in China-the absolute value encoder!
Absolute encoder, which is the most critical high-tech in servo motors or servo systems.
When the robot is performing an action, how to determine the spatial coordinate position in the action? How to ensure that every action accurately reaches the specified coordinate position?
For example, when a robotic arm rises and rotates 360° at the same time, how can the robot determine that its position is different from before?
Don't talk about seeing with your eyes, the robot is brainless, it can't understand.
This is the role of the absolute encoder.
Absolute encoder can determine that each position is unique according to the encoding.
And... even after a power failure, the robot will not lose its coordinate position.
Every movement of the robot, which joint should be moved, are all realized by the servo motor driven servo system. Therefore, the absolute encoder in the servo motor is the core of the core.
Absolute encoder is a kind of mechanical encoding.
The advantage of mechanical coding is that it is not affected by power outages and electromagnetic interference. As long as the absolute encoder is not damaged, it will not be affected by any external influences, ensuring that the robot can accurately complete the required actions under complex conditions.
At present, there are still big shortcomings in this technology in China.
For Lu Li, this was another "plagiarism" process.
The robot technology in the refuge technology has a high-precision multi-coil absolute encoder.
In the underground laboratory of Baoshan Base, Lu Li sat at the computer desk and began to "plagiarize" the design of the encoder in the refuge technology.
This copying process was very easy, and Lu Li quickly completed the design of the absolute encoder for the private server system.
Next, Assistant Lu Li let Tian sent some materials, using the high-precision laser processing equipment made before, and manufacturing parts one by one according to the design drawings.
The 64-pass absolute value coding lithography technology is two times higher than the 16-pass lithography technology used in the world today.
In half a day, Lu Li produced a complete set of servo motors.
After testing with equipment, the newly designed and manufactured servo motors have several times better performance than the best products in the world today.
The servo motor has completed the technical research.
Now, the reducer is absolutely dead, the servo motor and servo system are also solved, and the control system has a gene chip, which is not a problem at all. So... try to be a robot.
Back at the office, Lu Li sat down at the computer desk again and took out the spider robot of Refuge Technology.
The main reason for choosing spider robots is that the structure of spider robots is too suitable.
In nature, human walking upright is the most unstable mode of motion, and falling on the ground occurs from time to time.
Eight-legged spiders are much more stable, and they are also adaptable to various complex terrains and complex environments.
So... the humanoid robot is actually the worst shape. A robot that walks on two feet is the robot with the worst stability, even if the feet are changed to a crawler mode.
Based on the spider form, a series of robots with various functions can be developed.
The spider robot in the refuge is a combat robot driven by a miniature fusion reactor.
Today, Lu Li hasn't come up with controllable nuclear fusion technology, so naturally there is no way to use fusion reactors to drive spider robots.
It's just...even if there is no fusion reactor, it is not a problem to use graphene batteries to drive the spider robot and let it work for about four hours.
Then...start!
Afterwards, Lu Li made a long list and handed it to Assistant Tian, ​​asking him to prepare materials and some common parts.
When the materials and parts were available, Lu Li plunged into the laboratory and began to make a "big toy".
The spider robot's support structure is made of carbon nanotube composite material, and the shell is covered with a layer of titanium chromium carbide tantalum carbide armor plate.
The shutdown drive components are equipped with a servo system and a reducer, the wire is made of graphene material, and the battery pack is a graphene battery pack.
On the head of the spider robot, a detector is also needed.
Lu Li took out the "video detection radar", "infrared detection radar" and "graphene millimeter wave scanning radar" from the refuge technology.
In the control system, Lu Li eliminated the graphene chip in the refuge technology and replaced it with a gene chip he researched.
The information processing ability of gene chip is stronger, and also has extremely high anti-interference ability. Except for genetically encoded information, no electromagnetic signal can interfere with the data processing of the gene chip.
These radar technologies are far beyond the actual technology. Lu Li had to make the parts of the radar himself.
Fortunately, the current processing technology is all automated processing, and 3D printing technology can also be widely used ~EbookFREE.me~ It is not too difficult to make these parts.
After spending more than a week in the base laboratory, Lu Li finally made this "big toy".
This is a huge spider.
Eight spider legs with a length of more than 1.5 meters support the body of the spider about one meter. The front of the head exposes a pair of sharp chelating mouthparts, which can be opened and closed like scissors.
The abdominal compartment at the tail is empty and can be loaded with the required ammunition.
As for the attack weapon... Lu Li didn't install it. If the military feels the need, it can install various machine guns, even individual missiles.
Take out a notebook and install the control program. As soon as Lu Li hit the enter key, the spider robot started with a beep.
The two compound eyes turned, scanning the surrounding environment. The high-performance gene chip instantly records the data scanned by compound eyes.
Lu Li put his finger on the direction key of the computer and pressed the direction key, and the spider robot instantly moved.
The eight spider legs moved quickly, their toes pressed to the ground, the soft material eliminated the collision sound, and the spider robot's movement became light and fast.
When he moved to the wall, Lu Li did not stop, and directed the spider robot to continue moving.
The next moment, the tip of the spider's legs of the spider robot protruded with spikes, rotated into the wall, and climbed vertically along the wall!
"Not bad!"
Lu Li smiled, turned his head and shouted outside the door: "Lao Tian, ​​come, I will show you a new toy."
"toy?"
Assistant Tian rushed into the laboratory with a bit of surprise.
Then... Fuck!
Seeing the huge steel spider crawling on the wall, Assistant Tian's eyes widened.
toy? You say this is a toy?
Such an awesome spider robot, you say it is a toy?
