Liu Lin accompanied Liu Guang and the personnel of Xianggong at noon After having a meal, because the negotiations had ended, they signed the patent authorization agreement, and sent the personnel of the two companies away.

Chen Guanjun and Guo Liang happily took the patent authorization agreement and left Jiu'an Technology to do their own big things.

Liu Lin returned to his office and prepared to continue sorting out the core accessories of the robot.

Bell... Bell... Bell...... Liu Lin's buttocks weren't hot, and someone called in again.

"Hey, Brother Li, what's the matter?" Liu Lin reluctantly moved his eyes from the computer screen to the mobile phone. Seeing that it was Li Fei's call, he pressed the answer button.

"Mr. Liu, is it convenient for you to answer the phone now?" Li Fei asked.

"Convenient, I'm in the company's office, what do you say?"

"Wait a minute, a leader wants to ask you something, hang up first, and call you by confidential phone later. ”

"Good. It seems that it is a secret, and Liu Lin's head turned several times.

Three minutes later.

"Hey, hello Mr. Liu, my name is Zhou Fansheng. It's from a naval research institute, and I want to ask you something?" An old voice passed into Liu Lin's ears through his mobile phone.

"Hello Mr. Zhou, what do you want to ask, just ask. ”

"The sewage treatment system developed by your company, I went to see it a few days ago, it is very magical, I want to ask if this sewage treatment system can achieve seawater desalination. ”

"Desalination. After Liu Lin heard Zhou Fansheng's words, he was stunned and asked, "Mr. Zhou, do you want to move this sewage treatment system to the warship?"

"Yes, Mr. Liu, you should also know how important fresh water is in the ocean. Every time we sail, we have to carry a large amount of fresh water, if your company can reduce the sewage treatment system, can be installed on the warship, it will be a very big improvement for our navy, whether it is seaworthiness or combat effectiveness, so I specially asked about the possibility of desalination. ”

"Mr. Zhou, if you want to use the sewage treatment system on a warship, it is theoretically possible, but for the time being, it is also very difficult for us. Liu Lin explained: "Whether it is miniaturization, seawater treatment capacity, or the control range of magnetic fields, this is not something that can be done in a short period of time. ”

“……”

"If relevant research and development is carried out, Mr. Liu, how long do you estimate it will take to succeed in research and development. Zhou Fansheng thought for a while and asked.

"I can't answer you about this for the time being, I won't know until I've sorted it out. Liu Lin continued: "Mr. Zhou, why don't you do this! How about I answer you after I sort out these questions?"

"Okay, then I'm sorry for you, Mr. Liu. Zhu Fansheng said happily.

"Okay, I'll get back to you in a few days. ”

“……”

Liu Lin spent three or four hours, and finally sorted out all the information of the robot, stood up and stretched his waist, this batch of accessories should be manufactured by himself, and the smelting branch can meet most of the materials, and the rest can be purchased directly on the market.

Liu Lin sent the materials that the smelting company could provide, the rough embryo data and sent it, and those that could be bought directly were directly purchased by the purchasing department.

Liu Lin looked at the rest of the information, Liu Lin scratched his head, thinking in his heart, is it to call Gao Bi, the accessories that were sent out to order just now were withdrawn.

Robots are mainly divided into four categories, including actuators, driving devices, detection devices and control systems, and complex machinery.

Actuator: that is, the robot body, its arm generally adopts a space open-chain connecting rod mechanism, in which the motion pair (rotating pair or moving pair) is often called a joint, and the number of joints is usually the number of degrees of freedom of the robot.

According to the different types of joint configuration and motion coordinates, the robot actuator can be divided into Cartesian coordinates, cylindrical coordinates, polar coordinates and joint coordinates. For the sake of anthropomorphism, the relevant parts of the robot body are often referred to as the base, waist, arm, wrist, hand (gripper or end effector) and walking (for mobile robots).

Drive device: It is a mechanism that drives the actuator to move, and makes the robot act with the help of power elements according to the command signal sent by the control system.

It inputs electrical signals, and outputs linear and angular displacements, and the driving devices used by robots are mainly electric drive devices, such as stepper motors and servo motor devices.

Detection device: It is to detect the movement and working condition of the robot in real time, feedback to the control system as needed, and adjust the actuator after comparing it with the setting information to ensure that the action of the robot meets the predetermined requirements.

The sensor as a detection device can be roughly divided into two categories: one is the internal information sensor, which is used to detect the internal conditions of each part of the robot, such as the position, speed, acceleration, etc. of each joint, and the measured information is sent to the controller as a feedback signal to form a closed-loop control.

One is the external information sensor, which is used to obtain information about the robot's operating object and the external environment, so that the robot's actions can adapt to changes in the external situation, so that it can achieve a higher level of automation, and even make the robot have a certain "feeling" and develop towards intelligence.

And Liu Lin used the first one.

Control system: This gap that may not be stuck for others is a simple thing for Liu Lin, and it can't be simpler, just ask An An to get it.

Now the actuator and control system are done, but the drive device detection device, these two can't be produced by themselves.

Is it going to be outsourced again, Liu Lin scratched his head, his company in the electronics industry can be said to be poor and white.

“? (??????????))) ≡=─”

"Alas"!

Liu Lin sighed, decadently leaning on the table, the company has no electronic foundation at all, it is always a big problem, it seems that the electronics also have to be prepared, because many equipment is becoming more and more intelligent, the proportion of electronic technology is increasing, and now they are developing new production outlets, many of which need electronic engineering technical support.

Fortunately, Liu Lin changed from the game to an electronic expert, and he could get people out in about a week, and when the company's electronic technology was not as good as he is now, he felt completely unable to start.

"What's the matter, how do you see your sad face. Zhou Ying knocked on the door, pushed the door open, and saw Liu Lin scratching his wrinkled forehead with his hand, walked behind Liu Lin, helped Liu Lin rub his temples and asked.

"When did you learn the technique!, it's very professional!" Liu Lin groaned comfortably.

"Born, you can't envy it!" Zhou Ying put her head on Liu Lin's shoulder, looked at the dense information on the computer screen and said: "I used to help my father knead it, and after kneading more, the technique will naturally come up, practice makes perfect, by the way, what are you here, so complicated, I feel dizzy!"

"Aren't I going to build a smart unmanned factory, so I'm going to build some industrial robots!" Liu Lin explained.

"Then why are you frowning, the industrial robot can be customized directly from the company that produces the robot!" Zhou Ying asked puzzled, hugging Liu Lin's stomach.

"That's too low-end, it doesn't meet my requirements at all!" Liu Lin shook his head.

"You mean to make it yourself, but does our company have that technology?" Zhou Ying gave Liu Lin a question mark!

"No, that's why I'm worried! Now the drive device, the detection device completely stuck me, these two technologies are electronic technology, and our company also knows in terms of electronics! It's basically 0! I've never invested in this main side. ”

"So what now?" Zhou Ying clicked her cute little mouth.

"Don't worry about it for now, let me think about it, anyway, I'm not in a hurry to use it. Liu Lin took his mind off the computer, raised his head to look at Zhou Ying and asked, "Why are you here, have you eaten?" ”

"Not yet, if I don't have anything to do today, I feel like I haven't been shopping for anything for a long time. Zhou Ying looked at Liu Lin expectantly after speaking, because Liu Lin was usually busy, and the time to eat was in a hurry, let alone going out shopping.

"Okay, anyway, this problem can't be solved for a while now, so let's leave him alone, go, and go shopping with my daughter-in-law today." Liu Lin saved the information, stood up and said to Zhou Ying: "Daughter-in-law, should we eat first, or go shopping first and then eat." ”

"I'm not very hungry right now, if you're hungry, then we'll go eat first, if not, then we'll go shopping and wait until we're hungry before eating." Zhou Ying said.

"Okay, listen to you! I'm not very hungry right now, so let's go shopping first, and we'll have a supper when we're hungry in the evening." Liu Lin took Zhou Ying's hand and walked out of the office.

Washington, M.

The National Laboratory directly under the Environmental Protection Agency is located in the MSID Laboratory in Washington. There are materials scientists led by Jackslin, Tom Green, a physicist, and an electronic engineer, all of whom are among the best scientists in country M.

This group of scientists, who are ranked No. 1 in country M, gathered at the MSID laboratory in Washington two months ago, and the brows of this group of scientists have not been raised since two months ago.

The MSID laboratory in Washington is definitely one of the top 10 laboratories in the world.

In the fields of materials research and chemical properties, environmental protection and energy research, it can be said that it ranks among the top three in the world, and there is no laboratory in country M that can compare with this laboratory, and its advanced degree can be imagined.

It is this one of the top three national laboratories in the world, where there are ten rotating shafts that imitate the treatment center of Jiu'an Technology's sewage treatment system, which are neatly arranged in the 100,000-level dust-free test area.

IN THE 100,000-LEVEL DUST-FREE LABORATORY, A LARGE GROUP OF SENIOR ENGINEERS SUCH AS JACKSLYN AND TOM GREEN LOOKED AT THE 10 SHAFTS QUIETLY PLACED ON THE TABLE, WHICH WERE THE MOST PRECISE SHAFTS THEY HAD EVER SEEN, BUT THE ACCURACY REACHED 0.001MM, WHICH WAS ALREADY THE HIGHEST PRECISION THAT COULD BE PROCESSED.

But the whole shaft is one less circle than Jiu'an Technology's, no matter how it is processed, there is no way to add the missing circle.

"Why is it that the drawings displayed by Jiuan Technology are 500 turns, and we can only process 499 turns at most, and how do they do it? We have the highest precision CNC five-axis machine tool in the world. Jackslin, who was dressed in white, did not give up, and turned the 10 reels twice and sighed.

"With the calculated amount, unless our accuracy is improved by another 100 percent, we can add the last lap!"

But according to the fax from Mazak, if you want to improve the machine tool by 100 percent on the basis of the current one, it is impossible to make it with the current materials, and no machine tool company in the world can build such a high-precision machine tool. ”

"We have the world's most accurate machine tools and processing technology, since Jiu'an Technology can build it, then why can't we? It must be something we missed?" Tom Green rubbed his brow and said to Jaxlin.

"That's going to ask God!" Jackslin sighed, "It would be nice if we could get a sample, as for us to refer to, now just looking at the pictures, it's too general!"

"Mr. Jackslin, if we can get a sample, maybe our finished products will come out, and now Jiu'an Technology is strictly guarding us at all, plus Huaguo ....."

"So Mr. Jaxlin, the matter of the sample is basically hopeless, and now we still have to figure it out on our own. ”

"Mr. Jackslin, this lap has been holding us back for two months, I think it's better to put this problem down first, just use 499 laps, try to make a prototype out to see how the effect is, and then consider it. ”

"What do you think, Tom Green, do you want to build one and try it out?" Jaxlyn asked Tom Green.

"Okay, let's try it first!" Tom Green couldn't solve the problem for a while, so after thinking about it, he decided to put it aside!

"Bring in the high-purity silver!" Tom Green said to an assistant.

When the assistant brought the high-purity silver, Tom Green took it, looked at the 10 reels on the table, and was silent......

Such high-purity silver is extremely fragile, and it has to fight with tofu, and it has to be pulled into a silver wire of 0.8MM, a full 499 circles, how to go around...

In the end, Tom Green smiled bitterly and handed the high-purity silver to Jaxlin, "How can we wrap up such a fragile and small silver thread?"

According to the drawings, these silver wires are to be wound around the hinge, and now the problem is that such high-purity silver is more fragile than tofu, and with a little force, it will definitely break in two.

Half an hour later, the undead people used all the methods they could think of, whether it was mechanical or manual, never more than two turns.

"Why can Jiu'an Technology do it, but we have the latest and most sophisticated equipment in the world, but country M can't produce it?" Jackslyn couldn't accept this fact.

Even the technicians around them, one by one, sat on the highly clean floor in despair as if they had been dying.

Sure enough, there is no harm if there is no contrast......

"Bump... Touch... Bump ......" A rapid knock on the door interrupted Liu Lin, who was thinking about how to do the robot.

"Come in?" Liu Lin said as he raised his head and looked at the door.

"Boss, something happened, people look at this?" Zhu Yanqing hurriedly handed Liu Lin a newspaper!

Liu Lin took the newspaper very suspiciously, and when he saw the headline on it, his eyes narrowed into a line "......"

ps: I sat in the car for a day today, and I couldn't feel at ease in the car, so I hurriedly rushed out 4000 words at night, and I sent it first.
