Many people gathered in the production workshop, and the master responsible for maintaining the machinery was surrounded in the center, helplessly watching the substandard products being produced.

Students and professors from collaborating universities who participated in the project were also troubled by these substandard products.

Hearing footsteps entering the workshop, everyone turned around subconsciously.

Seeing that Yuan Jin was coming, everyone felt relieved and automatically moved out of the way.

"Is it because the joint joint accessories are not up to standard?" Yuan Jin glanced at the accessories placed on the table and said as he walked, "The dimensions are not right or is the movement laggy after being installed?"

"The size is wrong and it cannot be installed smoothly." The master said worriedly, "There are only a dozen pieces of joint joint accessories produced this time, and all of them are unqualified."

According to the design drawings, the joint accessories must be able to swing up, down, left, and right in order to have the flexibility of the joints reaching the level of the human body.

Conventional joint joints use balls or movable bolts, which can move up and down and forward and backward more flexibly. The design of the drawing is an oval strip shape, like the femoral head of the human body, to facilitate the connection of auxiliary sensor lines.

The accessories produced cannot be installed at all.

"It's just a dozen pieces, it doesn't matter." Yuan Jin picked up the finished product and looked at it, then walked to another table and tried to install the accessories on the robot's leg joints.

The size is much larger, it can't be installed and there is no place to arrange the wiring.

She studied it carefully for a while, then turned to look at the die exit of the production machinery. She did not use the joint joint method of the robot dog's legs. She used an interstellar housework robot, which is completely close to the joint joint method of the human body and can simulate the human body to the greatest extent.

behavioral actions.

To achieve a completely anthropomorphic effect, the flexibility of each joint is higher than that of a robot dog, and the balance design requirements are also very high.

"There doesn't seem to be much problem with the size of the die opening." Yuan Jin looked at the die opening and tilted his head to signal the master to start the machine and watch the production process carefully.

These flexible metal materials are imported from abroad and use new metal-based materials with conductive and sensing properties. There are also similar metal-based materials in China, but the impurities are too high and are not suitable for processing such accessories.

She had seen the material properties before. There should be no swelling during the production process. This metal-based material is resistant to high temperatures, has high flexibility, and can be folded and stretched. It is the most ideal robot bone material, and it is also relatively close to the material properties of interstellar robots.

.

Others didn't know what the problem was and followed her silently, waiting for her to find out the reason.

The production machine was restarted, the crawler at the feed port moved, and the new parts appeared on the finished product conveyor belt after multiple processes, but the size was still wrong.

Yuan Jin asked the master to shut down the production machine, take away the newly produced parts, and go to the feeding port to compare the color and texture of the materials.

The colors of the raw materials and finished products do not match. The color of the finished product is obviously darker, as if it has changed during the production process.

"The current application field of this material is relatively narrow, and it is basically only used to make prostheses. Is it because the grinding and extrusion during the production process caused the material's properties to change and expand on its own?" Someone asked.

"This possibility cannot be ruled out." Yuan Jin replied, removed the remaining raw materials, replaced them with another material, and signaled the master to restart the machine.

If the problem is with the material, change it to a material that can be used normally.

The robot has fire prevention settings. If the material changes under high temperature, the robot will crash instantly.

After waiting patiently for ten minutes, the new finished product came out, with the size exactly as required in the design drawings.

Yuan Jin found the reason, but frowned even more. The flexibility of the other material cannot be compared with the imported material, and it will increase wear and shorten the service life.

The biggest advantage of the robot is that you pay a one-time fee and receive free maintenance and upgrades in the future to add more functions.

If the service life is too short, the advantage of competing with caregivers will be lost. Good caregivers will do their best to take care of the service recipients, and no matter how high the monthly payment is, some people can afford it.

Robots mainly serve the public, and the price is a medium price that every family can afford, and they cannot use the money of ordinary caregivers to do work that is not as good as ordinary caregivers.

"I'll think of another way to see if I can find alternative raw materials." Yuan Jin picked up the two finished products and said to the master who maintained the machinery, "There is no problem with the machine, but the problem is with the materials we use. You guys

Let’s all go and rest.”

The masters all breathed a sigh of relief and went to check various switches in the workshop.

Yuan Jin took the finished product to his office and paced back and forth with his lips pursed. Imported flexible materials are the most ideal materials for joint joints. It is not easy to find replacement materials in a short time.

After spinning for a while, she stopped and sat back at her desk, opening her laptop to check the ingredient list of imported materials.

I wonder if it would be possible to remove one of the ingredients that may cause the properties to change?

Yuan Jin read the ingredient list provided by the material supplier and found that a few key ingredients were missing. He tapped his fingers on the table and picked up the phone to notify the professor from the project partner university to come in.

Kaiyuan Technology’s housework robot project has invited artificial intelligence research teams from two polytechnic universities to participate.

Program codes teach students that they can write more programs and apply them to other aspects based on the code structure.

The use of materials and robot testing can also allow them to gain experience.

I don’t need to go to a university to be a teacher, I can teach my skills to those who want to learn through projects.

After making the call, Yuan Jin continued to study the missing components of the material and thought about the possibility of replacement. If the properties change during the production process, it may be a problem with the production machine, or other metals may be mixed in during the processing, causing the properties to change.

changes occur.

This special flexible material will undergo unpredictable changes if a little more metal is added.

This is the most critical accessory of the robot. If the material is not suitable, no matter how well the subsequent accessories are made, it will affect the final result.

If you break down the proportions of all ingredients, you can clearly see where the problem lies.

Materials with secret ingredients like this were not allowed to be exported at all. She used some other means to buy them, originally with the idea of ​​deciphering the ingredient ratio.

This is also one of the reasons why she invited artificial intelligence research and development teams from universities to join the project.

After a while, the two professors knocked on the door and came in. They each pulled out their chairs and sat down.

"As for the composition ratio of this material, please arrange for people to do experiments, calculate the results, and we will synthesize it ourselves." Yuan Jin said the purpose of inviting them, "I suspect that the metal components released by mechanical wear during the production process affected the

Final properties.”

When the two professors heard this, they both fell silent.

Yuan Jin looked up suspiciously.

"Your analysis direction is correct, and the experiment is not difficult to do. We will prepare immediately." One of the professors said, "It's just...does the result of this experiment belong to your company or the school?"

Yuan Jin was stunned for a moment, then reacted, with a relaxed smile on his face, "The results of the experiment belong to you, I only need the finished product, and I will provide you with the cost and venue of the experiment."

They brought students to participate in this project, and it was unjustifiable that they had no results. No matter what aspect, they had to have something to offer.

"That's no problem, let's prepare for the experiment now." The professor also laughed, "Just wait for the results of our experiment."

"Be quick." Yuan Jin nodded with a smile, "This is an important raw material for robot joints. The faster the results are produced, the shorter the time for our robots to be put on the market."

The two professors nodded again and stood up together to go out.

Yuan Jin continues to study the reasons for changes in material properties and considers which materials can be replaced.

The robots in the interstellar world can be as flexible as humans. After setting the program, they will automatically calculate what they need to do and what work has been completed based on sensor recognition and calculation.

Even if Kaiyuan Technology's housekeeping robots cannot be completely human-like, they should at least be able to take on the work of nannies and caregivers.

It doesn't matter if it's a little slower, the worst she can do is design a matching smart kitchen system.

Once the cooking problem is solved, other problems will be easier to solve.

Yuan Jin listed the names of several alternative materials, picked up the phone and notified all employees in the R&D department to hold a meeting.

There are still many areas that need to be adjusted in the program. First, perfect the program, wait for the robot to be assembled, and then write the program and then make further adjustments based on the test results.

Walking into the conference room with her laptop, all the department managers and colleagues were present. She sat down, opened the program modifications they submitted, added logs, and said with a smile, "Who wrote this program?"

Before she went to study, she asked them to add functions to the factory program based on the work content of the nurses.

The □□ function is in the first line of the log, which is a bit confusing.

Customers who purchase robots need to fill in a functional requirements form before purchasing. The robots sold will add corresponding functions to meet the needs of customers based on the requirements they fill in.

Previous user surveys conducted online showed that most people's needs are to buy food, cook, wash clothes and clean.

Other functional requirements are not too high.

There are also those who are causing trouble, expressing their hope that the robot can have the function of a spouse.

"I wrote it." Someone raised his hand hesitantly.

The others laughed and asked him to explain the characteristics of this function.

The modification log only contains those functions that have been modified and added, but the specific functions of these functions are not written.

The person who raised his hand said weakly, "This function is not literal, but a night guard. For example, some sick old people will suddenly vomit at night when they sleep, causing the vomit to block the trachea and pass away. The robot's night guard

The model can prevent this from happening.”

"But the robot originally has a night mode. It can use sound and other sensors to sense people who need care and whether they need services." Yuan Jin curled his lips and opened the description of the night mode function of the housekeeping robot. "Night mode can not only

It can sense whether you need care, and also has the function of calling the police and dialing emergency calls.”

There is not much need to write one more code.

"I'll think of other functions." The employee lowered his head in embarrassment.

"Before writing new function code, you'd better understand clearly which modes are included in the main code, and additional functions must run in this mode." Yuan Jin smiled and continued, "The housework robot has three modes, housework mode and companionship mode.

mode and night mode, all the functions that need to be added will be implemented through different modes."

She alone has limited ideas, otherwise there would be no need for a R&D team and she could just find a few people responsible for maintaining the program.

Human beings in the interstellar world are very healthy and very few people get sick. All genes that can cause illness are deleted before birth.

The core code she wrote referenced some of the problems she encountered when she was a doctor, but it was not detailed enough and needed more people to brainstorm.
