As soon as they heard Marit's shout, Jermaine and Riley immediately looked at a certain someone. They didn't need to check to know what kind of situation the peacekeeper was in, so they naturally looked at the initiator.
But Lin was also confused, because he wasn't the one who did it. Then the only possibility left was … He turned to look at the Lich who was sitting in the carriage.
She was originally indifferent, staying in the depths of the carriage where the sunlight couldn't reach. At this moment, the Lich poked her head out and looked at Marit, or rather, the peacekeeper, with interest.
"Ah!" Lin suddenly thought that the Lich might want to do something. The peacekeeper, who was standing straight, raised its right foot in a rather unnatural position. It looked like it wanted to take a step forward, but the result of this step was that it fell directly to the ground. Then, the peacekeeper, who fell to the ground, continued to move its legs in that strange position.
"Is this not working?" Fen whispered to herself.
"So the peacekeeper can be played like this." Lin walked closer to the carriage and said to Fen, who didn't quite understand why she had failed, "Your control just now wasn't good. Walking didn't just depend on the joints of the crotch. Moving one's feet forward counted. The joints that have to be moved at the same time are the knees and ankles. Moving all three joints is the first difficulty. And to consider this, the most important thing is to coordinate the position of the overall center of gravity. The reason why you fall is because the center of gravity is moved to a position outside the fulcrum, and the subsequent movements don't move the center of gravity back to the fulcrum before the overall balance is destroyed. In other words, to be able to walk normally, you have to consider the overall coordination and balance. It's not like you can just raise one leg, put it down, raise the other leg, and put it down again to be able to move forward. "
"Yes, it really isn't simple." Fen nodded in agreement.
However, the peacekeeper, who had fallen to the ground, was still moving its legs. Of course, the people trapped inside would not have a good temper either. Through the loudspeaker of the helmet, Marit continuously scolded in the dwarven language, "Let me out! See if I don't beat you to death, you tall fellow! I've always thought that humans can't be trusted, and only that useless idiot would listen to you. You see, if I come out and find out, I'll beat you all up. Let me out! '
Fen, who was thinking and reviewing the contents of the procedure, was annoyed by the female dwarf who was yelling at him. With a flick of his finger, he turned off the speaker of the peaceful armed forces, cutting off Marit's ability to communicate with the outside world.
This also made everyone present, except for Lin Hefen, who was seriously discussing the key points to pay attention to when the robot moved. Everyone else looked at the peaceful armed robot lying on the ground and kept swinging its legs back and forth.
Everyone's expression was different. Halumi and Kaya both had curious expressions on their faces. Peace equipment was a new thing to them. Everything was new to them. Jermaine and Riley had an 'I knew it' expression. Although they wanted to save him, they didn't know where to start. On the other hand, Freya, Marit's female companion and Riley's partner, was looking at the scene in front of her with a thoughtful expression.
Although the coordination of his movements could be explained by himself, it would be easy for others to understand. However, for a certain Lich, he could not understand the importance of the center of gravity to the balance and the role of the support point. Fen could understand the theory and description of mechanics, but she was a little obsessed with the effects of those changes in reality.
So a certain someone, who didn't know how to explain it in words, gave up thinking of examples and how to describe it in words. He directly commanded everyone and said, "Stop the peaceful armed forces' abnormal movements first, so that I can explain it to you. Halumi, help this heavy guy up from the ground and make it stand up straight. Kaya, give me that Arcane Eye. "
"Yes, Teacher."
Of the three people in command, only Kaya answered. However, the other two still did what they were told to do meticulously. When Halumi was about to help the peaceful armed forces up, Jermaine and Riley also helped in a flurry.
The peaceful armed forces stood in the most natural standing position. It was an upright posture like a giant bear, with its upper body slightly tilted forward. The reason for this posture was that the battery-like relay power supply device, combined with the armed forces' control center, was installed on its back, at the same level as the shoulder line. The device wasn't light. It was only in this posture to maintain balance.
However, this wasn't the example that Lin Xiang wanted to use to explain. After receiving the Arcane Eye from Kaya, Lin activated the function that he had designed a long time ago but hadn't used many times. A fan-shaped green light swept down from top to bottom and scanned the entire peaceful armed forces. Then, on the other side of the Arcane Eye, a 3D image that was identical to the peaceful armed forces was projected, except that there were only lines and outlines.
Because he had just received the peaceful armed forces, he didn't have time to measure the weight of all the parts. So, Lin stuffed the parameters of his body and weight into this 3D image, and added additional weight data to the additional device on his back.
Under the calculation of the program, the position of the center of gravity of this 3D image was quickly obtained, and it was specially marked with different colors to distinguish it from the lines of the outline.
Because Lin didn't design the robot's movements, he directly used magic to control the peaceful armed forces' movements on the 3D image. And every time there was a change, the position of the center of gravity would be recalculated. So, Lin Caibian explained, "The most important support point for a human is the feet that are in contact with the ground. To maintain a standing posture, the simplest way is to keep the center of gravity within the support point. What will happen if the center of gravity isn't in such a position? "
As he spoke, Lin fiddled with the 3D image to lean forward a little more, but the position of the feet didn't change. As he expected, the calculated center of gravity had already deviated from the original position to a place beyond the support point of the feet. Also, under the effect of the simulated gravity, the peaceful armed forces in the 3D image fell with its butt to the sky and its face to the ground.
The result of the simulation surprised a certain Lich, not to mention the others. Dan Fen, on the other hand, asked about the reliability of the simulation program. She asked, "How did you design this?" At the same time, she pointed at the 3D image and asked, "And how did you get this?"
Lin said proudly, "This scanning program was originally designed to target mazes and buildings."
"Huh, didn't you use sound waves to target mazes and buildings?"
"That's right. Because sound waves are more useful, they can ignore corners and depths and explore places that can't be seen. This includes places such as dark rooms. This imaging method, which is mainly based on optical scanning, can only be used in places that can be 'seen'. It's not as convenient as sound waves, so I abandoned it. But later, I discovered that it's more accurate than sound waves to scan the appearance of certain small objects. So, I've kept this method and used it according to the situation. "
"Then what's the purpose of this simulation?"
"It's to consider where the weak points are when you want to destroy a building. That's the purpose of this simulation. It's to find the main load-bearing pillars or walls. When you want to destroy a building, of course, you have to target those main parts. If you target other parts, it'll be a waste of effort. "
"You're thinking about tearing down a building before building it?" Fen was rather speechless about the original purpose of the detection spell.
Lin didn't say anything else and simply explained the 3D image of the peaceful armed forces. "All in all, when the center of gravity is shifted beyond the support point of the feet, the object can only continue to change its position and center of gravity under the effect of gravity until it finds the next support point."
Then, Lin put the peaceful armed forces back into a standing position on the 3D image and changed its posture several times, each time different. The goal was to move the center of gravity to different positions. In the end, the simulation program would make the peaceful armed forces fall to the ground in all kinds of strange postures.
Fen gently pinched her beautiful chin as she looked at the simulation schematics. After a moment of silence, she said, "Does this mean that if I want this stupid thing to walk, the coordination of its movements must consider the position of the center of gravity, so that it can always maintain a position within the support point? And this center of gravity will constantly change its position as it moves. "
"That's right."
"That's really troublesome. Then I'll just stuff a Holy Spirit or Evil Spirit into it to control it. It'll be more convenient. "Fen was a little discouraged by the unexpected trouble and said with a little impatience.
"That's right …"
"You look like you want to say 'but'. If you have something to say, just say it. "
"The traditional way to control magic puppets in the Mystic Land is limited by the size of the magic puppets. Isn't that right? "Lin suddenly changed the topic.
Fen quickly replied, "So you're thinking of building a Titan?"
"Hehe, why not?" A certain someone's fake smile pointed out the main point, making Fen shiver. That's right, why didn't I think of that?
In traditional magic puppet technology, the larger the body, the more powerful the spirit was needed. Titans were undoubtedly the best magic puppet technology, but even in the era that Fen grew up in, no one had ever succeeded in building one.
The Titans that were still alive all originated from an even more distant era. Moreover, to be able to move a body that was several stories tall, the spirit that resided in it was unimaginably powerful. They were not inferior to the Homo sapiens in terms of intelligence and logic, and they had social skills. So much so that the artificial Titans gathered together and called themselves a race.
The reason that the Homo sapiens couldn't build Titans after that was because they couldn't find a spirit that could move the body. Someone had tried to mix multiple spirits together and stuff them into the body. The result was that the crazy giant caused unimaginable damage. But programming languages didn't seem to have that kind of limitation.
Fen's heart was filled with eagerness as she thought of this.
