() As soon as they heard Marit shouting, Jermaine and Reilly immediately looked at someone. They don't have to check to guess what kind of situation this peace force is facing, so of course they look at the perpetrators.

But Lin also felt forced because he didn't do it. Then the rest of the possibilities are ...... He turned to look at the lich in the carriage back to the tent.

Originally indifferent, he stayed in the depths of the carriage, and there was no sunlight. Then the lich poked his head out and looked with interest at the dressed Marit, or rather, the peace-armed.

"Ahh It occurred to Lin that this lich might be trying to do something. I saw the peaceman standing upright, in a rather unnatural posture, raising his right foot straight. It looks like you want to take a step forward, but the result of this step is to fall directly to the ground. Immediately after that, the peace fighters who fell to the ground continued to stagger their legs in that strange posture.

"Isn't that okay?" Fen asked herself in a low voice.

"It turns out that the peace armed forces can still play like this." Lin approached the carriage and said to Fen, who didn't quite understand why he had failed, "You can't control it like that just now." The action of walking is not only based on the joints of the hips, but also counting if you move your feet forward. At the same time, the joints to be moved are the knees and ankles. The linkage of the three joints is the first difficulty. And to consider this, the most important thing is to coordinate the position of the center of gravity of the whole. Falls occur because the center of gravity is shifted outside the fulcrum, and subsequent actions do not move the center of gravity back to the fulcrum before the overall balance is disrupted. In other words, in order to be able to walk normally, the focus must be on overall coordination and balance. It's not about lifting the leg up, putting it down, lifting the other leg and putting it down again, so that you can move forward. ”

"Well, it's not simple." Finn nodded bluntly in agreement.

However, the fallen peace forces were still moving their feet in a staggered manner. The people trapped inside certainly don't have a good temper, and Marette kept yelling in dwarven language through the helmet's PA device: 'Let me out, and see if I don't beat you tall guy to death!' I've long thought that humans can't be trusted, and that's the useless idiot who listens to you. You see, if I come out and know, will I beat you to the ground. Let me out! ’

Fen, who was thinking about and reviewing the content of the procedure, was annoyed by the female dwarf who was scolding. With a flick of his fingers, he directly turned off the speaker of the peace armed forces, cutting off Marit's ability to talk to the outside world.

This also made the people present, except for Lin and Fen, who were very serious about the key points that needed to be paid attention to when discussing the movement of the robot, everyone else looked at the peaceful armed forces lying on the ground and kept swinging their feet back and forth.

Everyone's expressions are different. Halumi and Kaya both had curious expressions, the Peace Forces were new to them, and everything was new. Jermaine and Reilly have 'I already knew' expressions, and although they want to save people, they don't know where to start. Marit's female partner, Reilly's partner Freya, looked at the scene in front of her very seriously, thoughtfully.

Although the coordination of the movements is explained by itself, it is quickly understood. However, a lich has not been able to understand the importance of the center of gravity to balance, and the role of the support point in this. Fen can understand the theories and descriptions of mechanics, but she is a little bit at the forefront of what the impact of those changes will have in reality.

Therefore, someone, who no longer knew how to explain in words, gave up thinking about examples and how to describe them in words, and he directly commanded everyone and said: "Stop the abnormal actions of the peaceful armed forces first, and then I can explain it to you." Halumi, lift the bulky creature up from the ground and make it stand up straight. Kaya, bring me that arcane eye. ”

"Okay, teacher."

Of the three people in command, Kaya was the only one who answered. However, the other two still completed the things they explained meticulously. Including when Harumi wanted to raise the peace forces, Jermaine and Reilly also helped.

The peace forces stand in the most natural posture. It was an upright posture like a giant bear, and its upper body leaned forward slightly. The reason for this is that the battery-like relay energy supply unit, combined with the armed control center, is mounted on the back, flush with the shoulder line. The weight of the device is not light, and it is necessary to maintain balance.

But this is not the example that Lin wants to explain. After receiving the arcane eye from Kaya, Lin turned on the function that he had designed for a long time, but had not used it a few times. A fan-shaped turquoise light swept over the entire Peace Armament from above. On the other side of the Arcane Eye, a three-dimensional image was projected that was identical to that of the Peace Force, but with only lines and outlines.

Because I had just received the Peace Armament, I hadn't had time to measure the weight of all the parts. Lin also took the parameters of his body and weight and stuffed them into this three-dimensional map, and added additional weight data to the extra device on his back.

Under the calculation of the program, the position of the center of gravity of this three-dimensional picture was quickly obtained, and it was specially marked with different colors to make it easy to distinguish it from the lines of the outline.

Because Lin did not design the robot's movements, he directly used magic to control the movements of the peaceful armed forces on the three-dimensional diagram. And every time there is a change, the center of gravity position is recalculated. So Lin Caibian explained: "The most important support point for the human form is the feet that are in contact with the ground. The easiest way to maintain a standing posture is to keep your center of gravity within the point of support. What happens if the center of gravity is not in such a position? ”

As he spoke, Lin leaned forward in the three-dimensional figure to move forward, but the position of his feet did not change. Sure enough, the calculated center of gravity has shifted away from its original position and is outside the support point of the feet. And under the effect of simulated gravity, the peace forces in the three-dimensional picture fell in a posture with their butts facing the sky and their faces against the ground.

The results of the simulation surprised one lich, let alone others. But Fen asked about the credibility of the simulation program and asked, "How did you design this?" At the same time, he pointed to the three-dimensional picture and asked, "And how did this come about?" ”

Lin said triumphantly: "This scanning and imaging program was originally used to target mazes and buildings. ”

"Hey, didn't you use sound waves to shape the maze and buildings?"

"Yes. Because sound waves are better used, they can explore places that cannot be seen, regardless of corners and depths. This includes some darkrooms and other places. However, this imaging method based on optical scanning can only be used where it can be seen, and it is not as convenient as using sound waves in use, so I abandoned it. However, it was later found that scanning the appearance of some small objects was more accurate than using sound waves. So I still keep this method and use it as appropriate. ”

"And what's your simulation focus?"

"Consider where the vulnerable point is when the building is to be damaged. It is the intent of this simulation to find the pillars or walls that are primarily load-bearing. When you want to destroy, of course, you have to target these main parts, and if you target other parts, it will be in vain. ”

"Before you build a house, you want to demolish the house first, you man." Finn was somewhat speechless about the original purpose of the detection magic.

Lin didn't say anything else, but only explained this three-dimensional diagram of the outline of the peaceful armed forces: "In short, when the center of gravity is displaced beyond the support point of the feet, under the action of gravity, the object can only continue to change its position and center of gravity until it finds the next support point. ”

Immediately afterwards, Lin reverted to the standing posture of the peace forces on the three-dimensional diagram, and changed his posture several times, each time different. The goal is to get the center of gravity to run to different positions, and eventually the simulation program will cause the peace forces to fall to the ground in various strange positions.

Looking at these simulation diagrams, Fen gently pinched his beautiful chin, and after a while, he said, "Does this mean that if I want this stupid thing to walk, the coordination of the movement must take into account the position of the center of gravity, so that he always stays within the support point." And this center of gravity will also change its position as it constantly changes. ”

"That's right."

"That's a real nuisance. Then I can directly stuff a holy spirit or evil spirit into it to control it, and it is more convenient. Fen said with some discouragement and some impatience at this unexpected trouble.

"That's right......"

"Look like you want to say 'but'. Say whatever you want. ”

"The traditional way of controlling the puppet will be limited by the size of the puppet, and it can't be too big. Isn't it. Lin abruptly changed the subject.

Fenkou quickly replied, "So you can't make Titans." ”

"Hey, why not?" Someone's smile that didn't smile made the point and made Fen feel excited. yes, why didn't I think of that?

In traditional puppet technology, the larger the body that can be driven, the more powerful the spirit is needed. The Titans were undoubtedly the most advanced puppet technology, but even in the era when Finn grew up, no one had ever succeeded in creating them.

The Titans that have survived have their origins in a much more distant era. Moreover, the body that can drive several stories high, and the spirits that reside in it are also unimaginably powerful, and they all have intelligence and logical abilities that are not inferior to those of Homo sapiens, and have social and interpersonal relationships. So much so that the man-made Titans gathered and called themselves a clan.

The Homo sapiens were unable to build Titans because they could not find a spirit that could power the huge body. Someone has tried to knead multiple spirits together and stuff them into that body. The result is the mad giants who have caused unimaginable damage. But programming languages don't seem to have that kind of limitations.

Thinking of this, Fen's heart became fervent again.
