"Uncle Wang, the villa near the golf course?" After the stock market ended, the old hooligan received a call from Manager Wang, rushed to the sales department, and asked.

"Yes, I also asked someone for a brochure of the villa, you can take a look!" Manager Wang handed him a few beautifully printed color advertisements on the table, and said: "The villa area covers an area of 5 acres, equivalent to more than 3,000 square meters, with outdoor swimming pools, tennis courts, small gardens, rockery pavilions, small bridges and flowing water, geothermal, central gas air conditioning, walls, the villa has a construction area of more than 4,000 square meters, one underground and two floors above ground. ”

The old rascal nodded while listening, and said, "Uncle Wang, there are enough houses, look at it, there are 3 large suites with small study rooms and large bathing rooms on each floor, 5 guest rooms with small bathrooms, and 1 large study room on each floor, so there are many rooms." In addition, there is 1 large communal bath, 1 sauna room, 1 gymnasium, 1 bistro, 1 main kitchen, and 2 auxiliary kitchens. Hehe, the garage is all in the basement, how many people are going to live?"

Manager Wang said with a smile: "Such a big villa does not have to live so many people, it is just a symbol of status." The price is 10 million, which is still relatively affordable, but this price does not include taxes, and it is estimated to be more than 12 million in the end. ”

The old hooligan looked at the structure diagram on the brochure and said: "It's just that the location is a little off, but this small bridge is flowing water or something, there is a shortage of water in Xijing, and it is estimated that it will be tap water at that time, and the swimming pool is quite large, exceeding the area of a basketball court." ”

"Well, although it is a little off, but fortunately, the transportation is more convenient, and the feng shui is still good. Manager Wang said.

Grandma's, if it weren't for my aunt and grandmother to build a laboratory, I would simply buy it in Qujiang, although it is much smaller, but that is a family villa, this big villa, I really have to raise a few beauties to stuff it into it to be lively, I and Fei'er, plus a nanny, are too lonely.

Thinking of this, the old rascal raised his head and said to Manager Wang: "Uncle Wang, how can I say it, the villas in Xijing, including the selection, design, and construction, are still much worse than some luxury villas in Xiangjiang and abroad, especially since there is no rich area in the surrounding area. ”

Manager Wang nodded and said, "That's the case, the domestic economy is not active enough now, and Xijing is indeed a lot worse than other first-tier cities." However, this piece can be regarded as a very good feng shui place in Xijing. There are a total of 8 large villas of various styles near the stadium, and 3 have been sold. ”

The old rascal said: "Okay, let's decide like this first, and when I have money in the future, I will go to Seattle to buy it and be a neighbor of Bill Gates, not to mention, I like to live in a villa designed by myself." This is not convenient enough in China now!"

Manager Wang smiled: "Then you can settle down, anyway, your funds are relatively abundant." ”

The old rascal nodded and said, "I'll go over tomorrow to take a look, if it's okay, buy it first, if you don't like it later, then change it for a better one, sell this one, and invest in it!"

Subsequently, when he inquired about foreign exchange, Manager Wang asked the old rascal not to worry, saying that Lao Song would definitely work hard if he had something sweet.

In the evening, several people excitedly gathered around the large experimental table in Professor Wang's laboratory, watching the old hooligan quickly piecing together all kinds of chips and circuit boards, connecting these electronic devices and subsystems, and then connecting them to the computer in the laboratory, and then taking out a CD in the bag and inserting it into the computer's optical drive.

"Okay, Professor Wang, it's up to now, victory or defeat is here!" After the old rascal finished speaking, he opened the folder in the CD-ROM drive, looked at Professor Wang and said with a smile: "This is our intelligent core program this time, it took a lot of money to get it, I also wrote a paper for this, and submitted it to the journal "Science", it is estimated that it should have passed the review of the editors and sent it to the experts for review, hehe, I hung Professor Wang as the fourth author, you all have a share, if you win, you can also be regarded as a bumper harvest this year." ”

When Professor Wang and the others heard this, they all showed surprise, and Professor Wang said, "Yifan, why didn't you tell me about this?"

"Didn't I tell you just now? didn't I tell you in advance, didn't it distract you?" the old rascal laughed, "Okay, I'm going to start transferring this core program to the control center of the robotic arm." ”

The control center is the hardware system that the old hooligan just put together;

Professor Wang put Science Magazine aside and watched nervously at the old rascal's movements.

After a few minutes;

"Alright, the transfer is complete. Let's simulate and test the operation of the control center!" the old rascal opened another program in the disc folder;

opened, the center of the software window is a three-dimensional robotic arm structure diagram, and on the right side of the window are some function clicks.

"You see, this simulation software, has been connected with our robotic arm control center, when I click on these function keys, the intelligent core program will control the three-dimensional structure of the robotic arm to change accordingly, in reality, if the robotic arm is pieced together, there will also be the same effect as in the structural drawing. ”

The three-dimensional structure diagram follows the old hooligan clicking on the function key, making various actions, such as stretching, contracting, lifting, hanging, pointing, drilling, cutting, stabbing and so on.

A few minutes later;

The old rascal said excitedly: "There are no big problems, some small problems are left for later and slowly improved, the titanium alloy skeleton I brought today can not achieve so many functions, after I install it, I will first realize the function of electric welding, you go to find a circuit board with holes and a few small capacitors." ”

Summoned by the old rascal was a young teacher, who hurried to rummage through a locker in the laboratory;

Professor Wang looked at these extremely fine titanium alloys and many connectors, and said, "Yifan, these are all ordered back from abroad? ”

"These things are very expensive, these two dozen skeletons and a lot of connectors, but they cost millions. The old rascal laughed, and then, with his hand wearing thin anti-electric gloves, he quickly picked up the metal skeletons one by one and put them together.

Ten minutes later, a robotic arm that is quite different from the structure diagram was successfully connected!

The female graduate student of Professor Wang next to him asked, "Do you want to find a soldering iron?"

"It's not over yet, the control center still needs to communicate with the connector of the titanium alloy arm, wait a while. Professor Wang saw the signs and replied to her.

After that, in the eyes of several people, the old hooligan connected dozens of connectors, and then connected a row of metal wires from the control center to one of the connectors of the port.

"Alright, bring me a soldering iron!" said the old rascal to the female graduate student, "and prepare the solder and wax on the side." ”

There are several common interfaces for the robotic arm, one with a soldering iron fixed and one tied with a solder.

After doing this, the old rascal began to operate the simulation software on the computer;

I saw that the robotic arm on the laboratory table immediately moved.

Professor Wang and the others suddenly exclaimed, and their voices contained joy and disbelief!

I saw the metal arm move slowly, making a slight metal friction sound, and move to the top of an empty circuit board with holes, and then, the soldering iron of one interface and the solder of the other interface on the top of the metal arm slowly approached the circuit board at the same time.

The heated soldering iron and solder hit the capacitor pin inserted into a hole in the board at the same time, and after a few seconds, the soldering iron and solder left the pin at the same time, and a small piece of solder with a very standard shape fixed the capacitor to the board.

"Great!" Professor Wang let out a heartfelt exclamation and said to the old rascal who had already stood up from the computer: "Yifan, this technology, I dare to guarantee that there is no scientific research group in the school that can compare with it!"

He was boasting about himself and flattering the old rascal.

"It's not particularly perfect, just now I operated it through simulation software, and our ultimate goal is to be able to autonomously weld this small capacitor through the self-recognition of the robotic arm. Also, the robotic arm still lacks several general interfaces and components, I didn't buy them, such as metal grabs, with it, just now we don't need to tie the solder to a small wooden stick and then connect it to the universal interface of the robotic arm, but can directly clamp the solder with metal claws. ”

The old rascal pointed out a few shortcomings, and said: "Come on, I'll try some other functions of the robotic arm, cutting and drilling, this circuit board is useless, right?"

A male graduate student hurriedly said: "It's useful, isn't it just soldered with a capacitor? ”

Professor Wang also smiled: "You go and get another scrap circuit board." ”

After a while, the universal interface on the robotic arm secures the next club driver and a hacksaw.

Later, the old hooligan returned to the computer, operating the simulation software, and controlling the robotic arm to make holes.

I saw that the plum blossom driver clicked hard directly on a discarded circuit board, and then separated from the circuit board;

I saw a small hole in the discarded circuit board;

The old rascal turned his head, looked at the experimental table, and said: "This test is just to verify this function, then we can connect a special drilling tool, this hole will be much more regular and beautiful, and then try cutting." ”

After speaking, Professor Wang and the others saw that the small hacksaw began to move on one side of the circuit board, making a screeching noise.

But this kind of noise is so comfortable to listen to the ears of Professor Wang, which is a kind of comfort brought by the joy of success.

"Okay, these little features are almost verified. The old rascal stood up and said to a few people who were still pointing at the robotic arm: "For the rest, Professor Wang, tomorrow you will go to some more electronic markets, buy high-quality electronic devices and circuit panels, and then contact the engineers and ask them to make the final few boards." ”

"Okay! I can get a good night's sleep tonight!" Professor Wang smiled, and then admired the robotic arm with excitement;

Under the fluorescent lamp in the laboratory, the robotic arm emits a light black sheen characteristic of titanium alloys.

Under the nostalgic gaze of a few people, the old rascal retracted his metal arm, and then patted the set of primary control center boxes, and said: "Professor Wang, I'll take this set of things first, I'll take a look, it's already past 11 o'clock, I originally wanted to invite you to eat some barbecue, but think about it is the day after tomorrow, I will invite you to have a big meal the day after tomorrow, and you go back tonight to have a good rest." ”

Professor Wang also walked over, gently stroked the very rough box, and said: "Alas, my old Wang has lived the most fulfilling life in these days for more than 20 years! ”

These days, the two young teachers and three graduate students who have been involved in this project have also lost a lot of weight, and they are also looking at the box at this time.

"This cooperation has been considered a success, you can rest assured, we will still have the opportunity to cooperate in the future, Professor Wang, go back tonight and have a good rest, and run again tomorrow, your task for this project is basically over, but when the final circuit board is made, I may have gone to the United States, and then you will use that kind of suitcase to install the final few circuit boards, and I will send someone to get it." Hehe, forget it, let's talk about it when we invite you to dinner the day after tomorrow!" the old rascal laughed.

Seeing the old hooligan's car slowly driving away, Professor Wang sighed again and said to several young people on the side: "Alas, you have worked hard recently, so rest well tonight." After speaking, he pointed to two of them, and said: "You two will go to the electronics market with me tomorrow, bring the list of devices, and then we will purchase higher-quality devices." In the afternoon, send us the engineer we contacted, and we will probably be fine, and I will treat you to dinner tomorrow night. ”
