"Yu, Yushan, you're here again..."
Seeing Yushan Kazuto, the experimenter in charge of model processing suddenly became nervous.
"It's been half a month, how is the progress?" Yushan Heren asked.
"It went smoothly." said the experimenter angrily.
"I'll go take a look." Yushan Kazuto walked to the super-precision machining system. An arm that was three-quarters completed was lying quietly in the processing room.
"What about the previous test data? What accuracy can be achieved?" Yushan Heren asked.
"It can almost reach the micron level. It will be difficult to go further down." said the experimenter.
Yushan Kazuto nodded. If they continued to explore deeper, it would be at the single-digit nanometer level.
The ultra-precision machining system itself is a nano-level processing system. To produce such a large arm, it is already very good to be able to maintain a precision of microns.
Just like an excavator, the vibration of the bucket at the end of the movement may exceed several millimeters. This arm can achieve an accuracy of microns, which is already very good.
Just thinking about the future, when the entire mechanical model is completed, the accuracy of the machine may further decrease, which made Yushan Kazuto frown slightly.
"Go test the movement accuracy of this palm." Yushan Heren took out the metal palm from his pocket and said.
The experimenter couldn't help but blink. The reason why he had to do everything again was because the movement accuracy of the metal hand didn't meet the requirements.
But listening to Yushan and others, it seems that the accuracy of the palm movement has been readjusted, which makes the experimenters feel a little
surprise.
"Wait a moment." The experimenter walked out of the ultra-precision machining laboratory holding the robotic arm.
Precision testing needs to be done on a specialized instrument, but unfortunately the ultra-precision machining laboratory no longer has room for such an instrument.
"Remember to do some ultrasonic cleaning first." Yushan Kazuto shouted.
The experimenter nodded and walked quickly in another direction.
……
About ten minutes later, the experimenter slowly walked back with the mechanical hand, his expression showing some disbelief.
"How is it?" Yushan Heren asked.
"After preliminary testing, we can achieve an accuracy of less than 20 nanometers. The specific value still needs further testing." The experimenter said with his head down.
He was a little confused as to what kind of adjustments Yushan and others had made to adjust the movement accuracy of the mechanical palm, which was originally at the micron level, to a level below twenty nanometers.
What does this mean? It means that you can manually adjust the CPU's precision.
Of course, using a lithography machine is definitely faster and more convenient than a robotic arm.
A photolithography machine can process tens of thousands or even hundreds of thousands of chips a day, but if you rub them by hand, you may not be able to produce even one in a year.
However, the accuracy it achieves has actually reached this standard.
If Yushan and others stayed by the super-precision machining system every day and constantly adjusted the robot palm, the experimenters would be able to understand the reason for the improvement in accuracy.
But Yushan Kazuto clearly took the mechanical hand home!
Chapter 1523 Compensation Algorithm and Development System
"Compensation algorithm, I think you can understand it, right?"
Listening to Yushan Heren speaking, the experimenters suddenly felt as if they had suddenly realized something.
"Does this mean that the motion accuracy is corrected through motion compensation?" the experimenter asked.
"Yeah." Yushan Kazuto nodded.
"So can this algorithm be extended to other devices?" The experimenter looked eager.
"In theory, it is possible." Yushan Kazuto nodded.
"If we look at the changes in the accuracy of the robot's palm, after motion compensation, the accuracy is improved by more than fifty times. If it is applied to the ultra-precision machining system..." The experimenters couldn't help but imagine.
"It's useless. The higher the precision, the smaller the effect of the compensation algorithm. According to my calculations, the best it can do is only down to ten nanometers." Yushan Heren said.
“Also, the compensation algorithm will have errors. The original precision of the ultra-precision machining system is high enough. After using the compensation algorithm, the precision may even decrease.”
Hearing this, the eagerness on the experimenter's face suddenly lessened a lot.
From this point of view, the compensation algorithm will only increase the workload for the time being.
Of course, this algorithm should also be useful in future designs.
After all, according to Yushan Kazuto, after compensation, the movement accuracy can be reduced to the ten-nanometer level.
This is already at the edge of ordinary super finishing systems.
"Well, could you please let me take a look at the source code of the algorithm?" the experimenter asked.
Yushan Heren nodded and took out a mobile hard drive, which had been prepared long ago.
Looking at the mobile hard disk taken out by Yushan and others, the experimenter couldn't help but blink slightly. Generally speaking, for a small algorithm, wouldn't it be enough to store it on a USB flash drive?
"To run this system, we may need a good server. I wonder if the main server of your 17th Laboratory of Science and Technology can support it." Yushan Heren said.
Originally, Yushan Kazuto asked Hui-chan to assist in the design. Hui-chan can call on more than 10% of the world's computing power at any time, so it is naturally easier for her.
However, when communicating with the 2th Laboratory of Science and Technology, Yushan Kazuto did not want to expose Hui-chan's existence, so he asked Hui-chan to package up some of the algorithms and functions he had used in the design process. As a result, the package was a giant package of nearly tb.
Looking at the huge object in the mobile hard drive, the experimenter couldn't help but feel a little dizzy.
"Don't worry too much about the package. Once the software is running, the compensation algorithm can be adjusted internally." Yushan Heren said.
The compensation algorithm is actually quite simple, only a few thousand lines, and was designed in more than half an hour.
However, the database used and some of the functions are huge.
The experimenter blinked slightly and tried running it.
Thanks to Huijiang’s optimization, it didn’t take too long to open the packaged software, only about ten seconds.
When it was running, the speed was acceptable, of course, it was still a lot slower than when Yushan and others ran it at home.
"Although it has not been debugged yet, it should be able to run." The experimenter observed it for a long time and said.
"That's good." Yushan Kazuto nodded.
"But what is the pre function? Why can't I see its definition?" the experimenter asked.
"Oh, don't worry about those. Those are the encapsulated parts and are in the database." Yushan Heren said.
The experimenter couldn't help but blink. He didn't expect that Yushan Heren had another trick up his sleeve.
Fortunately, the code of the compensation algorithm alone was enough for him to study for a long time.
In fact, there wouldn't be too many problems if all the codes were made public, but Yushan Kazuto was a little worried that if all the codes were made public, the experimenters might study the codes day and night, and the progress of the actual work would be delayed.
Taking this factor into consideration, Yushan Kazuto chose to encapsulate it.
“Adjust to another interface and perform image processing.”
Yushan Kazuto casually pressed a button on the keyboard, and a model of a mechanical hand appeared on the screen.
"The reaction speed is quite fast." The experimenter couldn't help but say.
“Uh…” Yushan Heren couldn’t help but blink.
He was a little hesitant about whether to tell the experimenter that the model had been preloaded.
If it is a brand new model, the construction speed is actually quite slow.
"Can all the bright spots on the model be clicked on?" the experimenter asked.
"Well, yes."
The experimenters were relieved, because there was a model before, which was the same as this one, covered with densely packed bright spots.
As a result, after he clicked it, the entire design system collapsed.
After that lesson, experimenters would be hesitant when seeing these bright spots.
Click on a bright spot on a joint at random, and the entire model will instantly enlarge, with every detail inside the joint clearly visible.
Dozens of different data pop up on the right side of the screen, which can be used to adjust various parameters within the joints.
"These parameters can also be adjusted, right?" asked the experimenter.
"Well, but my suggestion is to conduct a simulation, use the feedback correction form, and then import it into the system for adjustment." Yushan Heren said.
The experimenter nodded. If he adjusted it at will, it might
It's a mess.
"As for the rest of the functions, they are all small plug-ins. If you want to know more, just open the Excel spreadsheet in the mobile hard drive and check it out." Yushan Heren said.
"I understand." The experimenter responded, switched the interface back to the code interface and continued his research.
"Now that the first hand is almost completed, developing the other hand shouldn't be a problem." Yushan Heren said.
The two hands have a left-right symmetry problem, and this cannot be used by simply reversing the parameters.
Some parameters do not need to be changed, some parameters need to be adjusted, and some parts of the code need to be adjusted.
However, compared with the first-hand development, the difficulty is more than an order of magnitude lower.
"But if we want to load this compensation algorithm." The experimenter was a little embarrassed.
"If it's difficult to adjust, just use the original parameters I left behind." Yushan Heren said.
He has adjusted this set of parameters many times. In addition, the software also has a self-identification function, so it actually has a certain degree of versatility in improving accuracy.
"We don't require the accuracy to be down to the ten-nanometer level, as long as it reaches the same level of accuracy as this palm." Yushan Heren said.
The experimenters breathed a sigh of relief. It was not too difficult to reach the 20-nanometer level.
After all, even the original micron-level precision of the robotic palm can be adjusted to the twenty-nanometer level, and the current robotic arm itself has a precision level of fifty nanometers, which is not at the same level of difficulty.
Chapter 1524 Is this your first time here?
"How's the talk going?"
Sitting in the car, Yushan Kazuto looked at Yukinoshita Yukino.
"We haven't reached a consensus on the price yet." Yukinoshita Yukino glanced at Yushan Kazuto and said in a low voice.
"Is the price very high?" Yushan Heren couldn't help but blink.
But it is normal. After all, for top laboratories, no amount of funding is enough.
Yukinoshita Yukino blinked slightly and said nothing.
The budget given by Mrs. Yukinoshita was such that the other party insisted on developing software that could only be adapted to one mobile phone system.
However, Mrs. Yukinoshita hopes to be able to adapt to all mobile phone systems.
It is difficult for both sides to reach a consensus on this point.
"How about I go and talk to them for you?" Yushan Heren said.
Yukinoshita Yukino shook her head: "No need, I have already communicated with my mother, she will come to negotiate by herself."
Yushan Kazuto couldn't help but blink slightly and nodded.
In fact, Yukinoshita Yukino also felt that the price given by Mrs. Yukinoshita was a little low, so low that it felt like exploiting the experimenters.
From Mrs. Yukinoshita's point of view, in her opinion, she has already designed an intelligent management system in the laboratory at a high price, and the following work is equivalent to after-sales service, so naturally she has to lower the price.
"Then...when will Aunt Yukinoshita come?" asked Yushan Kazuto.
"Maybe next week." said Yukinoshita Yukino.
Yushan Kazuto blinked slightly and started the car.
Hearing that Mrs. Yukinoshita was coming to Tokyo, Hayama Kazuto felt a little uneasy for some reason.
……
When I got home, Tsuchiya was already asleep on the sofa.
Yushan Kazuto couldn't help but roll his eyes and told Domama to take a rest for a while, but he didn't expect that she actually fell asleep.
