Chapter 105: Humanoid Machines

"Of course, I tell you this truth so that you should learn to be prepared for danger in times of peace, not to teach you how to quibble", Wang Yinan added, "There are counterexamples in everything, and there is no disadvantage in using quibbles, because no matter how good the argument is, you can always find examples that are not applicable".

"The last truth is the summary of my decades of life experience, I hope it will be of some help to you", Wang Yinan continued, if it weren't for his identity as a double Nobel Prize winner, if he was so blind on stage, it is estimated that he would have been thrown rotten eggs a long time ago.

Less than thirty years old, tell us the philosophy of life, who are you?

But now, even if Wang Yinan farts, most of the time he will say "good smell, good smell", or at least say, "good sound, good sound".

"It's never too late to do something, and every time you feel it's too late and want to give up, it's actually too late," Wang Yinan said.

Although Wang Yinan himself is a "counterexample of becoming famous as soon as possible", this truth could not be stronger.

Balabala, let's do it, after boiling chicken soup for half an hour for the employees of Deshi, Wang Yinan ended his speech, in the thunderous applause, Wang Yinan gained the attribute of loyalty collective +1, if you play a slight game of domestic policy, basically others have no way to poach.

After completing this unplanned work, Wang Yinan was finally able to breathe a sigh of relief and went to a relatively small laboratory at the back of the workshop.

The laboratory is not big, but the lighting is very good, and the bright and flickering various light-emitting diode lighting equipment illuminates everything in the room, and as soon as Wang Yinan walks in, his eyes stay on the humanoid robot in the center of the room.

This is a very tall humanoid monster, and many years ago there was a science fiction movie, called "Martian Invasion", in which the Martians sent to the earth combat robots are a little similar, of course, shorter, the combat robots are each tens of meters high, equipped with super turrets.

The robot is about two meters tall, about the same size as a tall human, and the entire control mechanism and the main load are in positions similar to the human hip joint, including batteries and various sensors. Here a dense network of wires sticks out and connects to each artificial muscle.

The lower body of the robot is very similar to the lower half of the human body, except for the skin that does not cover the bones, the basic bones, and the muscles that drive the bones (albeit artificial), including the connections and cushioning devices between the bones, are no different from real people.

Wang Yinan approached the tall robot, the robot did not rely on its own strength to stand up, but through a bracket behind it, the main bones were fixed, barely maintaining a standing shape, if this bracket was removed, it would turn into a pile of mud in minutes.

After carefully observing the interface part of the thigh bone and the calf bone, Wang Yinan also picked up a bone on the test bench on the side and weighed it, it was really very light, but it was very strong, and it should be made of carbon fiber composite materials.

"What kind of technique do you use for this joint between bones?" , Wang Yinan pointed to the part where the thigh bone and the calf bone are combined, and asked Deng Weiguo, obviously this question is beyond Deng Weiguo's ability, "I am the workshop director, not the chief engineer", Deng Weiguo muttered, beckoned to the technician wearing a white coat on the side, "What technology is used in this joint part?" Deng Weiguo asked,

"This is an air cushion, we use the principle of shock absorbers used in high-end cars, specially customized inter-bone air connection device", the technician is very proud to say, "no maintenance, the cost is also very low, in case of damage, just replace one",

"And the cushioning effect is very good, basically the best hydraulic buffer effect can be achieved, but compared with the hydraulic buffer, we are completely maintenance-free."

Wang Yinan looked at the small, black washer-like thing between the bones, "This thing is so good?" He took out an independent gadget from the experimental cabinet next to him and handed it to Wang Yinan, "This is a miniature air suspension", "You can try it."

Wang Yinan picked it up and studied it carefully, the thickness was less than 0.5 cm, and the two sides could be directly bonded to the bone, Wang Yinan pressed it hard with his hand, and it seemed to be a little deformed, "It looks good", Wang Yinan said, put this thing on the ground casually, and then occupied it, and stepped on it hard,

"It's very good, it's a bit like my Air Jordan 12th generation shoes," Wang Yinan said.

"Speaking of which, we can still make sneakers in the future, this shock-absorbing effect, there is nothing to say."

"That's good", Wang Yinan was very satisfied with the things in front of him, and he walked quietly, which was a necessity for killing people and setting fires.

Deng Weiguo poured a large basin of cold water on the side, "It's a pity that I can't stand up, all the joints are alive, if the muscles are all in a tense state, you can maintain an upright position, but in that case, we have tested it, and when we touch it lightly with our hands, it will be in an uproar."

"That's because the current robots have no souls, of course they can't stand up", Wang Yinan said very proudly,

"By the way, what is the battery capacity of each of your units and how long can it work?" , Wang Yinan asked,

"You don't have to worry about this", Deng Weiguo is still very clear about this data, "There is no problem with working continuously for more than three months, according to the consumption of normal people walking, you can directly replace the battery for half a year and a year, and you don't have to think about charging."

Wang Yinan took out his laptop and connected to the base's Gödel system through the VPN, "Are the precise weights of each bone and the response curves corresponding to the artificial muscles ready?" Wang Yinan asked,

"I've been ready for a long time", this very bullish technician casually called up a document, "Professor Wang, how can I give it to you",

"Near-field communication", the two took out the device, exchanged the verification code, and sent this data to the Gödel system in the imperial capital.

The Gödel system, which has been trained countless times in an abstract virtual experimental environment, fine-tunes the trained neural network according to the latest data received, Wang Yinan glanced at the notebook, "The adjustment can be completed in ten minutes, this time it will not be compiled for the time being, the neural network of the Gödel system directly controls this thing remotely",

"After all, there are still some differences between the simulated and the actual machine, and the neural network that manipulates the machine must be adapted and adjusted again on the actual machine to achieve an ideal state."

While waiting for the Gödel system to adjust the neural network, Deng Weiguo secretly pulled Wang Yinan to his side, "said,

"What are you doing with your stuff, it's not like you've watched too many Gundam anime, so you're going to get a mecha warrior."

Wang Yinan immediately scoffed, "I never watch cartoons in that island country, except for some films that are not coded",

"That was developed for the military? Super Special Forces? Deng Weiguo asked,

"Maybe there will be such a possibility in the future, but now there is only one use", Wang Yinan's eyes showed a sad look,

"I promised someone to bring him home."

Deng Weiguo suddenly thought of something, the turmoil in the media some time ago, and the unfinished summit of Laihi live broadcast, he pointed to the sky, "Do you mean him?" ”,

Wang Yinan nodded, "Yes, so I have to train this thing to climb next."

Looking at the robot's simple upper body with only upper arms and lower arms, Deng Weiguo was a little puzzled, "It's still far from this now?"

"The road has to be walked step by step, and the rice has to be eaten bite by bite", Wang Yinan said.

"Although I'm very good, I also know the truth of being greedy and chewing too much, so let this thing stand up, walk, and run first."

"The upper body design with fingers is almost complete, and you will have to work hard then."

While speaking, the adjustment of the neural network of the Gödel system was also completed, Wang Yinan used the mobile phone as a router to directly connect the robot with the neural network of the Gödel system, the first part is to test the actual response curve of each bone and muscle, after all, any theoretical value must be reflected in the actual control process.

I saw that the various joints of the robot began to move from slow to fast, swaying up and down, left and right, slowly lifting, slowly putting down, quickly lifting, and then quickly putting down.

After the robot had a convulsion for a few minutes, it slowly calmed down, Wang Yinan's mobile phone, "beep" rang, "Static detection has been completed, dynamic balance training can be carried out", Wang Yinan "clicked" and took several photos, Deng Weiguo wondered, "What is there to take pictures of this thing", he asked Wang Yinan suspiciously.

"If you don't take it now, if the Gödel system throws it apart, you won't be able to shine it again", Wang Yinan said with a smile.

"Me x", Deng Weiguo almost scolded, "You dare to love yourself, you are not sure", picking up the mobile phone, Deng Weiguo hurriedly "clicked" several photos.

"Tear down the shelf", Wang Yinan said, Deng Weiguo nodded, "No problem, anyway, it's yours to fall apart."

I don't know if it's an illusion, Deng Weiguo felt that after the shelf was removed, the robot seemed to be shaking a little, "Why is it shaking", Deng Weiguo shouted loudly, "Will it fall down?" ”,

"Shaking is normal, and the Gödel system is building a negative feedback control loop through a small range of jitter," Wang Yinan said.

"You know the negative feedback, right?" , Deng Weiguo almost didn't turn his face with Wang Yinan, "Anyway, I'm also a professional in automatic control, and a master of workshop technology, what do you mean by asking?" ”,

"Negative feedback means that the power generated by each feedback is less than the applied force, and the direction is opposite, so that after many negative feedbacks, the power of the system will become zero, and the system tends to stabilize," Deng Weiguo said.

"Positive feedback means that the power generated by each feedback will be superimposed on the original power, so the output will become larger and larger, and the system will become very unstable."

"That's right, so positive feedback is used to do work, and negative feedback is used to control", Wang Yinan continued, "Do you know what the most bullish positive feedback is? ”,

"I don't know, your question has no beginning or end, who can answer it", Deng Weiguo shook his head,

"The fission reaction of the atomic bomb is the most bullish positive feedback example," Wang Yinan said.

"After the mushrooms, not a single inch of grass grows."
