The housekeeping robot failed to pass the laboratory test. The overall balance was not stable enough and the joint movements were not flexible enough. The problem lies in the algorithm. The laboratory mode program written by the R&D department was unable to calculate the correct instructions.

Yuan Jin led everyone to re-modify the code and conduct experiments again.

The results of the second test were better than the first, but there were still many problems. She listed all the problems that occurred during the test, gave the R&D department two days to modify them, and wrote another laboratory mode program herself.

My own technology is higher than that of this world. The entry settings left when writing the main program structure did not consider the current technical level, which led to frequent situations.

Two days later, the R&D department wrote a new laboratory model program, and the third experiment began.

Yuan Jin holds the controller outside the laboratory, controls the robot in the experimental area, and performs the simplest actions according to the instructions.

The results of this experiment are better than last time, and the incompatibility problem still exists, but it is a lot better than the previous time.

"Do you want to change the program you wrote?" The head of the R&D department said weakly, "The program code we wrote is incompatible with the main program, and the algorithm speed is also different."

She said with certainty before that there would be no risk of leakage of all the information collected by Kaiyuan Technology’s housekeeping robots.

Everyone was full of confidence and felt that they could write a data encryption protection system that no one could break. Now I know that the boss said that the information would not be leaked because she was super skilled, rather than really believing in their abilities.

After the laboratory mode program code is connected to the main program, it uses different algorithms and cannot obtain results within the preset time. The main program often misjudges that there are no instructions. This makes the robot motionless as if it is suffering from Alzheimer's disease.

Downtime.

After the supervisor said this, his back straightened unconsciously, "We studied the structure of the main program in private, but we didn't understand it clearly."

"I'll teach you later. Let's finish today's experiment first." Yuan Jin stared at the housekeeping robot in the laboratory and continued to issue instructions for cleaning.

The housework robot that receives the instruction uses sensors to slowly identify and find the tools needed for cleaning in the laboratory.

The head of the R&D department calmed down and worked as her assistant to record the data.

The third experiment lasted two hours. After receiving the instructions in the laboratory, the robot was basically able to complete the instructions, but the movement was stuck for a long time. Youzhong woke up and found that the work was not finished yet, and then continued to work.

feeling.

Yuan Jin switched the robot program to working mode, released the initial installation laboratory, set the destination as the scene simulation laboratory, and let the robot go there on its own.

Everyone followed the robot and headed to the scene simulation laboratory in the experimental area.

There are ten house types in the scene simulation laboratory. Different living environments such as two-bedroom, three-bedroom, and villa are built with simple boards, with different furniture and complete kitchens and bathrooms.

Housework robots need to complete different work contents in these different house environments. In addition to residences, there are also relatively complex places such as supermarkets and farmers' markets, hospitals, pharmacies, etc.

When the robot switches to working mode, its movement speed is similar to that in the laboratory, and the problem of balance becomes obvious.

Everyone held their breath, fearing that the robot would suddenly fall over, but they didn't dare to get too close for fear of being hit.

Yuan Jin also noticed the problem of balance and tilted his head to signal the head of the R&D department to record it and continue to observe the performance in other aspects.

The sensor installed on the face recognizes the environment very smoothly, and performs well in obstacle avoidance and going up and down stairs.

Entering the scene simulation laboratory, Yuan Jin chose an apartment with two bedrooms and one living room, and controlled the robot to enter through the controller.

The robot entered the laboratory, and others followed her into the scene simulation laboratory control center to continue observing the robot's reaction in working mode.

"I remember there is a cooking program. Can you add recipes by yourself?" The employee standing next to the supervisor whispered, "Can you cut the vegetables with your hands?"

The supervisor gave him a blank look and told him to shut up.

The employee laughed dryly, raised his hand to cover his mouth, and opened his eyes wide to see the robot's performance through the floor-to-ceiling glass.

The robot entered working mode, shook its body and head, and recognized the environment through its facial sensors and lenses. After a pause of about three or four seconds, it began to go to the kitchen to open the refrigerator and check the ingredients stored in the refrigerator.

It's almost noon now, and according to the program, the robot needs to prepare lunch for the employer.

Seeing it starting to take out ingredients, everyone held their breath again, with their hearts in their throats.

There was a crisp sound of "pop", and the eggs in the robot's hands fell to the ground, all shattering into pieces in the bag. The air suddenly became quiet, and everyone subconsciously covered their mouths, secretly watching Yuan Jin's reaction with their peripheral vision.

Yuan Jin pursed his lips and concentrated on it.

The program is not perfect yet. Cooking requires processing various ingredients, the power setting needs further adjustment, and the balance problem must also be solved.

The robot in the laboratory seemed to be in standby mode again. After a while, it picked up the bag containing the eggs and hesitantly put it into the trash can.

Then, the housekeeping robot took out cucumbers, sliced ​​meat, and tofu prepared in advance from the refrigerator.

According to the normal process, it should first clean the cucumbers, and then process the cucumbers until they are ready for cooking. I don’t know whether it is a programming problem or a calculation error. After getting the cucumbers, the housekeeping robot stood in front of the refrigerator in a daze.

Yuan Jin took the computer from the head of the R&D department and checked the data response just now.

There is no problem with the program, the problem is with the algorithm.

After waiting for about half a minute, the robot put down the cucumber in its hand, opened the dishwasher, and took out the knives and plates from the dishwasher.

The clanking sound instantly spread throughout the scene simulation laboratory.

Yuan Jin raised his hand and pinched his eyebrows, stopped the robot's scene simulation experiment, and motioned for everyone to sit down in their respective seats for a meeting to solve the problem at hand.

The action of the housework robot is still very obvious, especially when identifying the next work content, the robot will stop as if it has crashed.

Occasionally there will be a particularly confused standby state, as if I don't know what I should do next.

The control center slowly became quiet. Everyone held their computers and waited expectantly for Yuan Jin to speak. She was the developer of the main program, and she completed the entire structure independently. The R&D department was responsible for other work content programs.

Write code to add.

The reason for the standby state seems to be algorithm incompatibility? If this problem is not solved, the assembly of the second robot may be far away.

The first two-room and one-hall scene simulation laboratory experiment was completed.

Yuan Jin cleared his throat, replayed the experimental scene on the big screen, and said calmly, "I believe everyone already knows where the problem lies. The next work will focus on solving the problem of algorithm incompatibility."

The programs they wrote under the framework adopted several algorithms that they are good at. The calculation time after formal operation is different. Before other instructions are completed, the main program will determine that there is no instruction and put the robot into standby state on its own.

"The responsibility for such a result lies with me." Yuan Jin spoke up again, calling up the algorithm he used when writing the main program code, and projected it on the big screen, "The algorithm used in the main program structure is the same as yours, it is just adjusted.

I have given you some values. I will give you a few more days to modify some of the codes you are responsible for."

The algorithm she uses is an advanced version of binary search, dynamic programming algorithm, singular value decomposition, etc. It can use the information recognized by the sensor to perform the fastest calculations and obtain the correct instructions.

The algorithm they used has not been adjusted, and the calculation time is higher than the waiting time of the main program, causing the main program to frequently misjudge.

"I have a question." The head of the R&D department raised his hand, "Boss, how did you come up with the idea to adjust the calculation method?"

Her major seems to be film and television post-production, right?

"You can figure it out after three more years of research and development." Yuan Jin raised the corners of his lips and smiled slightly, and projected the steps of adjusting the main program algorithm on the big screen, "It's not particularly complicated. I'll give you a few days to learn and master it.

.”

Everyone fell silent again, as if they were back in school days. Listening to the top student said that this question is not difficult for you to change your mind.

Are they unwilling to change? Are they unable to change?

Yuan Jin saw everyone's reactions in his eyes and couldn't help but smile, "If three days is not enough, then one week."

"One week." Everyone shouted in unison.

Yuan Jin agreed and announced the adjournment of the meeting with a smile.

She did not consider at the beginning that even with the same algorithm, there would be incompatibility problems. Her knowledge was ahead of theirs, and the reserved interfaces should be set according to their average level.

The housework robot project was once again suspended due to algorithm issues, but Kaiyuan Jewelry became unexpectedly busy.

Sending Gu Hengzhi to the detention center and filing a lawsuit with Furui Jewelry were on the hot search for half a month. Kaiyuan Jewelry became famous overnight.

More and more customers are applying for customization, the number of employees in the customer center has increased from one to five, and the recruitment of designers has also been put on the agenda.

Many customers who sent emails to apply for customization asked Kaiyuan Jewelry when it would add old jewelry repair and refurbishment business.

Yuan Jin listened to the assistant's report on the customization applications received during this period, looked up from the screen, and asked with a smile, "Are there many customers asking about the repair and refurbishment business of old jewelry?"

She decided to become a jewelry designer because she met a young couple in Gusha Town who wanted to exchange their mother's gold bracelets for their wedding dowry in exchange for three gold medals.

"Not too many." The assistant lowered his head and flipped through his work iPad, found an email about repairing jewelry and handed it to her, "This customer sent 7 emails, and the content of each email is full of hope.

We can help repair a pair of dragon and phoenix bracelets that his grandmother saved."

The customer said in the email that the craftsmanship of this pair of dragon and phoenix bracelets is quite complicated. Ordinary gold shops and jewelry processing shops cannot complete such difficult craftsmanship.

Yuan Jin took the iPad from her hand, read the contents of all seven emails, raised his fingers and tapped them lightly on the table, and said, "Contact the other party and tell him that he will send the necessary information."

Bring the repaired jewelry over and I can decide whether it can be repaired after looking at it.”

There is a photo of this dragon and phoenix bracelet in the email. The craftsmanship is indeed complicated. It uses filigree inlay and engraving. It cannot be solved by ordinary craftsmen.

Master craftsmen who have learned these two intangible cultural heritage skills have no time to take on such small and medium-sized orders.

The assistant nodded obediently, "Okay."

Yuan Jin returned the iPad to her and continued to look through the customization applications received during this period.

For the two sets of jewelry designed and produced by Designer Wang, she did not charge processing fees or design fees. The new contract should indicate the specific amounts of the design fees and processing fees, allowing the customer to choose whether to continue customization services.

The program adjustment of a housekeeping robot may not be completed in a week. Customized jewelry orders usually take one to two months from design to finished product.

She can take the time to go to the three-dimensional sand fixing truck factory and take a look at the specific structure and production process of the sand fixing truck.

The design drawings of Zhongzhi Machinery are now complete. She has also shortlisted manufacturers that can produce large-scale wide and narrow rollers and is ready to contact them for production.

The machinery behind the truck that separates seedlings, plants them, and irrigates them requires program control. She has finished writing the program and is currently looking for a manufacturer that can trial production.

Yuan Jin multitasked. He went through the work arrangements in his mind, picked out four more sincere customers, and sent the list to his assistant, "Notify the customer center to contact them and explain our customized service content and delivery.
