"Alright, today I've talked a lot about my personal matters. Your situations are different from mine, so you need to realistically assess the current situation, including when the machine is running. I will set some problems for you to research. Remember each question, okay?" brother Dau spoke endlessly about his experience buying a house. Before saying this, brother Dau tactfully complained, "The interest rates nowadays are ridiculously high." As he complained, he skillfully took out a cigarette, lit it, leaned against the wall, showing no expression on his face.
"Where's San?" Zhang Xu turned his head and noticed one person missing.
"He's in the restroom. This guy drank so much water, won't he make himself uncomfortable?" Liu Shuai glanced at the distant restroom door. Wang San leaned against the wall, sighed deeply as if relieved, "Look at his bear-like appearance. Lao Zhang has to stop him. Drinking so much water will upset his stomach," Zhang Xu teased, Liu Shuai smiled, and San continued eating in silence.
"During this period, I've paid the interest first. I can't delay it. The child... let's leave him at our hometown for now. It's not suitable for him to be here." brother Dau spoke softly, his face turning solemn. Yes, for the sake of life, he had accumulated the remaining 10,000 yuan from his monthly salary of 8,000 yuan and other bonuses, but under the pressure of the house, 6,000 yuan disappeared. His son was also facing the high school entrance exam, and finding a good middle school would require a lot of money. Perhaps there were many people like brother Dau in this city, not in the same place but experiencing similar worries at the same time.
"Okay, that's it. Don't mention this to Mom and Dad." brother Dau finished speaking and hung up the phone, took a deep drag on his cigarette, calming himself down.
The three men didn't know what was said on the other end of the phone, but brother Dau's expression told them that they couldn't chat anymore. Perhaps their lunch break would become very short, or they would have to wait until brother Dau calmed down before they could continue. So the three of them quickly cleared the table, grabbed the trash bag, and headed to the smoking area.
"Watch the flowers bloom and wither, and watch the clouds roll and disperse." This poem seemed to depict the three men's state after temporarily leaving brother Dau. The garden outside the smoking area seemed to be the only quiet place apart from the clashing of steel, the roaring of machines, and the shouting of various workers. Through the window of the smoking area, they saw the clouds opening and dispersing, the sunlight going from dazzling to hidden, and then flickering to the point where it was impossible to keep their eyes open, making the three men's mood, like brother Dau, go from dark to bright.
"Even if the future stops, the words are blocked, and the door is closed, even if you lose sight of the painful times and the wrong path, show the strength of the black ant colony. Even if it's fading, believe in life." Wang San hummed a few lines in Japanese, and his face relaxed a lot. It seemed as if he wanted to sway with the rhythm. His fingers moved as fast as a guitarist's, plucking each string and every note.
"You haven't played the guitar in a long time, have you?" Liu Shuai asked, watching San's fingers make accompanying solo movements.
"It's been about half a year, hasn't it?" Wang San continued humming the accompaniment, his fingers moving rapidly. "You see, you're the only one who can relax. The two of us can only watch how TMQQ is handling the gunfights," Zhang Xu and Liu Shuai were engrossed in the annual CF competition. As Ouyou took down the opponent's sniper with one shot, AG secured a crucial point, entering the second half. Through the phone speaker, the excitement could be heard, and the cheering overflowed from the screen.
At this moment of unique tranquility, as if rejecting the addition of smoke, the three sat in the open space outside the factory. Zhang Xu made drumming motions, Liu Shuai and San played solos. The quiet was temporary, but it didn't lack a bit of relaxation and joy.
But in this factory where there was almost no leisure time, this slacking off behavior was soon met with brother Dau's urging, "Alright, time's up. Do as we discussed earlier." The three mischievously stood up, dusted themselves off, "Okay, brother Dau," they said in unison, and hurried back.
Contrary to the three's expectations, the robot wasn't set up and waiting for operation. Instead, brother Dau had deliberately stopped it here, repeatedly performing the action of taking photos. It seemed to be the first challenging task prepared by brother Dau.
The parameters on the computer were all normal, with a screen full of green parameters, giving no clue to Wang San at first glance.
"Now it's up to you to solve this. This is the first problem that occurs when the robot is actually executing a task: after taking photos, it stops in place and doesn't continue executing the command. I won't give you any information now. The only hint is that the first four in the row all have this problem. You need to discover and solve it on your own." brother Dau had a serious expression as he sat behind the three.
"Before actually going in, think about how to proceed, make sure everything is in place." brother Dau spoke again, looking at Zhang Xu with a serious expression as he revealed his dyed yellow hair. Zhang Xu smiled awkwardly and quickly got his equipment ready, dressing neatly.
After saying this, brother Dau made a decision that shocked the three of them: he actually lay down on the chair and fell asleep. Wang San ran over to ask, but only got a response: "I've made it clear what needs to be done, why waste time? You three can handle it, I've figured it out, go ahead." brother Dau impatiently pushed Wang San away, rolled over, and started snoring.
Following brother Dau's instructions, Zhang Xu zeroed the robot's speed, released the robot from its reset, and entered the robot's work area. Wang San quickly arrived at the controller, observing their every move.
In the slot where the robot stopped, there was a component. Zhang Xu boldly moved it, then left the work area and reset it. "San'er, give it some speed, take a photo and try again." Zhang Xu stared at the computer next to Liu Shuai, where the screen displayed the unsuccessful recognition image, so Zhang Xu quickly took another photo.
The new photography began, the robot raised its head, the camera flashed, the recognition model on the screen appeared, and two seconds later turned green. Wang San jumped the speed to 30, and then a magical scene unfolded: after the recognition result turned green, the robot began to execute the grab, raised its head, turned the camera to the other side, and slowly descended near the component, extending its own gripper. There was a sound of "ding," and the object was picked up!
As the robot moved slowly, with the eyes of the crowd closely following, the part fell into the transport line slot, and the processing of the first part was successful.
"Speed to zero, I'll go take a look again." Zhang Xu took the controller, set the speed to zero, followed brother Dau's instructions, turned off the reset, and entered the work area again. The part in the second slot was not askew, so Wang San and Zhang Xu exchanged gestures, restored the reset, and continued to observe the shooting results.
"Look, it's green in the picture, but it just won't move." Zhang Xu walked over to the computer to ponder the recognition results, while Wang San went into the work area to check the situation of the material rack. The bottom plate of the first layer had a slight depression, measuring 6 millimeters with a caliper. "It's sunken?" Liu Shuai was surprised. The equipment that had been running steadily just a few days ago suddenly had a depression. The three people's eyes converged on brother Dau, who was sleeping. "It seems like he went to a lot of trouble to test us," Liu Shuai commented, then found a hammer and lightly tapped a few times. Wang San took out the caliper again, and the 6 millimeters decreased to 4 millimeters. Returning to the computer for recognition, Wang San restarted the robot, the shooting light lit up again, and the recognition result on the screen turned green. The robot began to lift its head and rotate, ready to grab. The group succeeded again, Zhang Xu took another successful picture, ready to proceed with the next part.
"Let's take a look at the next one, it's probably a placement issue." Zhang Xu gave Wang San a look, and Wang San nodded. Zhang Xu went in to observe, and the part in the third slot showed a more obvious placement deviation, shifting slightly to the left. After a slight adjustment, Zhang Xu walked out of the work area, and the group restarted the photography. As with the previous times, the robot grabbed the part again. Over the next half hour, the group gradually resolved all the slot issues. After finishing these tasks, the group sat down to discuss. As the end of the workday approached, the noise of the machines gradually quieted down, and the voices of the group began to drown out the machine collisions. The smoking spot opened its door again, and the group stood up, ready to relax.
"How did you guys do?" brother Dau stretched and stood up, looking at the parts on the transport line. "Not bad, go take a break," brother Dau nodded in satisfaction. It seemed that his judgment was correct. These three kids were the first group brother Dau had trained. In the factory, where there was generally opposition to the popularization of robot projects, brother Dau insisted on keeping the robot project team. For this, brother Dau often argued with the leaders in private. So, before the arrival of the three, brother Dau's engineer nomination had been taken by another person named Lao Yu. However, although brother Dau saw all this, he did not make a fuss about it.
The three of them smoked, watched the clock, and counted down the time to the end of the workday, chatting about the girl from the previous night. "San, tonight, you better do well. The girl is a good one," Zhang Xu suddenly spoke, leaving Wang San stunned. "What are you talking about? I don't even know her name. Stop talking about unrealistic things," Wang San laughed. The girl in the shop was the boss's niece, named Fu Qiyue. In their initial online exchanges, they had left a certain impression on each other.
"Don't hold back your brothers. In your three years of college, besides being with books every day, you haven't talked to any girl who has feelings for you. Do you know how much that hurts them? My classmates have told me a lot about your matters. Really, listen to your brother. It feels like this girl has feelings for you. Don't miss out. When you start working, you'll have a partner. Otherwise, how will you handle your family? Your family won't accept you not getting married!" Zhang Xu spoke earnestly, like a concerned mother. "Yeah, you're right, but don't rush me. I'll make something of myself, brother," Wang San was a bit impatient but couldn't say it directly, so he proactively lit a cigarette for Zhang Xu. Liu Shuai laughed heartily on the side, "What's this? Even old Zhang has these urgent moments?"
Three people laughed heartily, waiting for time to pass a little, chatting and laughing about their plans after work.
Unusually, music was played in the factory, with the sound of the flute lingering like the bright moon over the river, the water flowing gently, and the small boat sailing on the river. In the vast sea, with an open mind, they could see the myriad stars and overlook the mountains and rivers in their dreams. Under this peaceful music, they waited for the shuttle bus after work. The three of them boarded the bus, leaving behind the brother Dau, who looked meaningfully at the young men in front of him, showing a relaxed smile.
