Yang Yue looked at the environment of the 408 dormitory with curiosity.

To be honest, there is not much difference from the dormitory when they went to school, the university dormitory has basically eliminated the shelf bed, and it is currently a quadruple room x lower table-bed combination furniture, the difference seems to be only in the "other people's dormitory" has air conditioning......

But he could see the difference at a glance, there was a weird-looking computer case near the balcony door in the dormitory, and two thick black wires stretched out from the back of the case and pushed straight to the balcony, through the open balcony door, he saw an object full of silver-white metal sheets outside, which looked like a radiator on a motorcycle engine.

"This is the server of Wave VOD, and on the balcony is its water-cooled radiator," Atletico said, from behind him.

"Heh," Yang Yue smiled awkwardly, he had heard of the water cooler used on the computer, but he had never seen such a big one. I don't know what he would think if he saw the water cooling system in the Internet café room of the space station, the water cooling system over there is connected to the tap water system of the entire Internet café (through the secondary exchange of heat exchangers, the cooling system is cooled with tap water), so that the water released from the bathroom faucet is always warm, and the boiling water in the canteen kitchen also saves some energy.

After a few pleasantries, the two sat down and began the theme of today's meeting.

Yang Yue is a reporter at the 173 online game portal, and today he made a special trip to interview the head of Bee Technology.

When Bee Technology contacted 173 to apply for the creation of the "Daming OL" online game area, the editorial department was very curious about this cutting-edge Internet company, which is also located in Fujian Province and is currently in the limelight, so there is today's interview.

Because it was difficult to take leave near the end of the term, Atletico Madrid arranged the meeting place in their dormitory, after all, it didn't hurt to wear the hat of "college student entrepreneur".

"A lot of boys should have had the experience of disassembling toys, radios, and game consoles by themselves when they were young, right?" said Atletico when asked how he embarked on the path of invention and creation.

"Of course, I wasn't in junior high school at the time, I didn't study physics, and I could use the toys as they were, but the radio didn't. I dismantled the radio and put it back on, it just didn't ring, and I was beaten by my dad. ”

Speaking of this, Atletico was suddenly silent for a while, staring out the window in a daze, and then he said: "My dad is a high school physics teacher, and after beating me, my dad threw me a full set of physics textbooks from junior high school to high school, and asked me to turn over the texts related to electricity by myself and learn it by myself, and if I can't fix it, he will beat me." ”

"This should also be regarded as a kind of stick education, right?" Atletico Madrid, who fell into the memory, unconsciously brought a smile on the corner of his mouth: "But my father's attitude has always been to make a mistake and beat me, and told me the solution to let me make up for it, and if I can't make up for it, I will continue to fight." ”

Yang Yue's mouth opened slightly, he didn't know how to interface well, when he was preparing before, he had read some family information about Atletico Madrid, and knew that his father had passed away.

"Anyway, that's how I started my physics course in the fifth grade of elementary school, but only in electricity. Atletico smiled slyly: "Because I don't want to be forced to learn mechanics, I won't go when other friends call me to play ball." ”

"Then when I was in high school, for you know, I used the hour before the evening study hall to set up a stall in front of the school to sell small goods. The main ones are all kinds of cheap headphones, pocket radios, miscellaneous solo players, and the external power supply of lead-acid batteries. These miscellaneous products are cheap but the quality is very unstable, and I can't pit my classmates, so I have to repair them myself, and if they can't be repaired, they will be disassembled into parts for other products. ”

Referring to his first invention, Atletico was obviously excited, "At first I just connected four earphone plugs to a connector, but it didn't work well because of the lack of power, and then I designed my own amplification circuit and finally did it." When that kind of dual earbud walkman was sold to us, my classmates and I thought it was plagiarized by someone else, and of course I ended up being alone. That was the first time I realized that the invention patent was very close to me. ”

Atletico stood up, took out a small box from the desk drawer, took out a black straight mobile phone inside and handed it to Yang Yue, "This is the first mobile phone I purchased spare parts and designed and assembled by myself." Of course, it is said that it is designed by itself, but in fact, it is just one more camera than ordinary mobile phones. Then I was interested in software programming because I wanted to constantly optimize the results of the dual cameras. And finally admitted to the Department of Computer Science of Lu University. ”

"It seems that most of your patents were applied for after you came to Ludao?" Yang Yue asked.

"It costs money to apply for a patent, and I can't do it naturally if I don't have money or time before. Atletico said depressedly: "In fact, although I have applied for more than a dozen patents, but now there is not a single patent certificate, although I have all applied for the publicity period in advance, but I still need to go through the process of one or two years, so I now strictly speaking there is no patent in hand, only a dozen patent application numbers." But I didn't expect that not long after I applied for disclosure, it was discovered and posted on the Internet. ”

Yang Yue: "I've seen your inventions on the Internet, and many of them look very interesting and concise. Can you tell us about your process and thinking about inventing these things?"

"The process is to open your mind," Atletico touched his scalp, "to be like a brother Hugh, often associate more, open your brain, and think of ideas." Many things that are commonplace in our daily lives contain new possibilities in them. Like this invention, can you tell what it's based on?"

Yang Yue turned his head to look in the direction of Atletico Madrid's finger, and on his desk, there was a standing beautiful doll wearing a long white dress.

Seeing Yang Yue's puzzled eyes, Ma Jing reached out and flicked the beauty doll, she lay forward, but quickly swung back and swayed back like a tumbler.

"Tumbler?" Yang Yue asked, but he himself didn't believe that it was just a simple tumbler.

Atletico smiled, did not explain, but tapped on the table with his index finger, and then Yang Yue was surprised to find that the beautiful doll actually began to move slowly, Atletico kept changing the position of the tapping, "she" also followed and kept moving, and at the same time, her arms would also make some stretching and opening movements, "It seems to be dancing?"

"Can't think of it, right?" Atletico didn't sell much, grabbed the dancing doll, and showed Yang Yue the underneath of her skirt.

"A ball?"

Under the wide ankle-length skirt of the doll, it is not the anthropomorphic foot structure or wheeled structure that Yang Yue imagined, but a black sphere.

"The official name of this should be the ball walking robot, and the 'line' is the walking line. Atletico said: "In fact, walking on the ball is a classic project of circus pattern clowns, and some of the actions in our national acrobatic top tank also have a similar principle to this." Generally, traditional robots will choose wheeled platforms to make them move, but wheeled ones don't seem to fit everyone's impression that robots should be humanoid, and they will feel awkward. Then one day I flipped over a mechanical mouse when I was flipping through something, and suddenly my brain was opened, isn't it a very good and concise mobile platform to use the mechanical mouse in reverse?"

"Under the mechanical mouse is a metal ball, there is a roller on each side of it in the vertical direction, the mouse mouse pad moves, the friction makes the metal ball roll, thereby driving the two rollers to roll, and the roller each drives the two grating signal sensors of the x-axis and y-axis, which converts the rotation of the roller into a digital signal like x+1 and y-1, so as to realize the capture of the mouse motion trajectory. The concept of my ball line is just the concept of a mechanical mouse reversed, and the data line transmits the digital signals of X+1 and Y-1, which drive the two vertically arranged motors to produce corresponding actions, drive the metal ball to roll, and finally drive the overall movement. Of course, although the concept is a reverse use of the principle of mechanical mouse, because the purpose of use is very different, the actual structure of the final is still different from that of the traditional mechanical mouse. ”

Of course, this metal ball does have some tumbler principles in it, but it is very light, and it is more of a principle of the clown standing on the ball to maintain balance and even move freely by constantly adjusting the speed of his feet. ”

Yang Yue took the doll from Atletico Madrid, she was wearing a miniature dress similar to a Barbie doll, and the big skirt was lifted up, but there was no beautiful scenery underneath, but a birdcage-like metal structure skeleton or skirt support.

Inside the skirt is the eye-catching black metal ball, Yang Yue tried the feel, there is a delicate friction feeling similar to a rubber pen cover. On top of the metal ball are two or two vertical three rubber wheels and the corresponding electric motor. Further up are the circuit boards and batteries inside the soft plastic case.

Yang Yue was surprised to find that the internal structure of this dancing robot was quite simple, even a little rudimentary, far less complex and sophisticated than he imagined.

"After all, we are learning computers, not mechanicals!" Atletico said bluntly, "The human arm is a shoulder, elbow, wrist three degrees of freedom link, and a large number of small joints form a more flexible hand, if the human arm is completely simulated human hand, the cost is too high, and the technical requirements are too high." We can cut off the legs of the dancing robot in order to save trouble, and naturally it is impossible to really restore such a complex arm. ”

The palm of this dancing robot is dead, and there are no moving parts in it, but there are small pieces of rubidium-iron-boron permanent magnets in the palm of the hand, which can absorb some iron props. The reduction of the arm to the shoulder fossa elbow link around the shoulder is in place.

Although the shoulder joint, as a typical ball-and-socket joint, is actually the same principle as Atletico Madrid's "ball walking" system, and theoretically it is completely possible to align the ball system to the shoulder joint, but the model puppet is too small and the ball travel system is only suitable for vertical use, so it is not suitable for it at all.

The doll's arms also use a hydraulic drive system similar to that of an excavator, and the arms can make various bending movements such as "V, L, J, and ∧" on the body plane, and the shoulder joints can be rotated at a certain angle, so that her arms can mimic human arms as much as possible.

This puppet robot is a simplified version of Thunderbolt Zero, with a greatly simplified structure, AI and functions, and only retains the ability to dance to the rhythm of the music.

Because there are still a lot of shadows of "Perak Five" in the appearance and concept of Perak Zero, Atletico Madrid has no idea of commercializing it, because the cost is too high and cumbersome. However, when he saw a message on the official website that someone (Zhao Xilin) asked Bee Technology to help him repair the broken AI wave robot dog, he had an idea and thought of the idea of making a simplified version of the AI robot.

Of course, it's hard to say that he didn't do this because he was not influenced by Japanese anime such as "Joomaru (RC Machine)" and "Rose Maiden". In fact, after Atletico Madrid successfully improved the brushless motor on the Mosquito No. 3, they really put a bunch of "really" in their trunk. 4WD. off-road vehicles", but because these little brothers are still not as good as four-rotor drones in terms of terrain adaptability, they were put on the shelf by Atletico except for a few games after they did it and remembered their youth ten years ago.

Dancing can be said to be the most suitable sport for robots, because the rhythm and standardized movements of dance make the movements more standardized and more suitable for robots to present. Especially mechanical dance, zombie dance, puppet dance......

For robots, as long as the joint hardware conditions allow, dancing is just loading and playing a piece of action command.

The dancing robot that was put back on the table is "singing and dancing" at the moment, and the dance is naturally not a ballet or folk dance that focuses on the softness of the body, but a simple and bright dance.

"This dance movement needs to be redesigned by a professional choreographer according to the characteristics of the robot's joints, and now I am messing around with it according to the dance video, and it may look relatively rudimentary. Atletico said with some embarrassment.

"Okay, I think it's very interesting!" Yang Yue nodded, and then asked: "Atletico Madrid, I just saw that her structure is relatively simple, and the degree of completion seems to be very high, do you have any plans to introduce it to the market?"

Atletico nodded in agreement, "Of course, the guiding ideology of our country's invention and creation is innovation and practicality, and we plan to officially unveil this dancing robot during CJ next month, and then there will be an online store for members to sell." ”

"When it comes to your company, what is the relationship between Bee Technology and you?"

"I use my technological invention to take a stake, so I guess I am one of the shareholders. ”

"As a cutting-edge network company established less than a year ago, Bee has grown rapidly in the last year, and now has a market share of nearly 20%. Atletico Madrid: What do you think is the secret of the rapid development of bees, and can you share it with us?"

"I should say that we just stepped on a key node, and we were lucky and tried to catch it. Before 05 years, most of the online games and application software on the network were charged, and the occasional free ones were cracked pirated software and private servers. Then the concept of free game props charging F2P appeared in the online game industry, and it developed rapidly, forcing a large number of new online games that use the traditional time charging model to all the big heels. Netpig Company's high-profile "Datang OL" launched last year had to be combined in large numbers because of the decline in popularity after the fee, and Ding Sanshi announced the launch of the free game "Datang OL2" without waiting for his mouth. At that time, this fire has only been burning in the online game industry, and most of the software in the software industry is charged, but our Bee Technology is the first large-scale genuine application software for everyone to use for free, so it has won great favor from users and business development is rapid. ”

"But the software is free to use, and how many users are the users who purchase value-added fees?"

Atletico shook his head, "If there are enough users who purchase value-added services, and deduct more than 100 annual membership fees, even if only one-tenth of the 300 million registered accounts open members, there will be tens of billions of income a year, how can it be only 2.8 billion? 300 million, and many of them are earned by selling emojis and qshow. ”

"Then how much money did your bee company make last year?" Yang Yue suddenly asked very gossipy.

"We are not a listed company, we don't need to publish financial reports, but we can't compare with these industry giants, just a fraction of what people do, or don't talk about it. Mulberry heart. ”

"So you also have a game project, and then you're going to exhibit at CJ this year?"

"Yes, the general consumer-oriented software market is not large, only the online game market is considerable, and countless companies have to jump into this puddle to catch fish and eat, and we are not willing to be left behind. ”

"I also heard that your Bee Technology opened an Internet café in Ludao last month, which is known as the first Internet café in the country, what do you think about the development of the Internet café industry now?"

Atletico Madrid replied directly: "Our country's Internet cafes have embarked on a very characteristic crooked path from the beginning. ”

"How?"

"Internet café is a foreign concept, the original English name intercaf'e, Internet café, originally referred to a leisure place that provides Internet services. Atletico Madrid: "Internet cafes are not common in foreign countries, just one of the cafes with different characteristics, but in our country, because the telecom broadband is too expensive and the Internet café pirated software does not cost money, the cost of Internet cafes is much lower than that of Internet access at home, consumers have walked into Internet cafes, and operators have made a lot of money." Other people saw the red eyes and stepped in, Internet cafes are opening more and more, and competition makes the unit price of Internet more and more cheap. What's more, with the development of technology, the cost of broadband and the price of computers are also decreasing, which on the one hand reduces the cost of Internet cafes, and on the other hand, it also diverts Internet café users. Therefore, we believe that traditional Internet cafes with local characteristics will become more and more difficult in the future, and it is normal for profits to decline or even close down. But at the same time, the real intercaf'e, as a leisure and entertainment place in the Internet era, still has its necessity and value of existence, it is impossible to say that the traditional bars, cafes and teahouses in the Internet era have not been finished, but the Internet cafes or Internet cafes have been poured first. Of course, there will be a significant reduction in the overall scale, which is part of the phenomenon of the first appearance of family planning achievements and the disappearance of the demographic dividend. ”

"In other words, you think that the Internet café industry will face a trend of downsizing and moving towards high-end in the future, so you tried to open a high-end Internet café?"

"Yes, and there is also the intention of using it as an offline base to facilitate the long-term collection of user feedback. ”

"So what do you think of the arguments that some experts and scholars on the Internet have called for the closure of Internet cafes and even the banning of video games?"

"Do unto others as you would have them do unto you. If the person who said this can guarantee that he will only be a noble and good person for the rest of his life like Uncle Lei Feng, and can really do it, let's talk about closing the topic of vulgar entertainment.
