"What is the key question?" Xia Fan was also very curious. What did he see? An ancient remote control toy! Being able to move means that it has a source of power; being able to control it remotely means that this power can be controlled by others!
As early as when he saw the spiritual platform, he had already wondered whether Qi and power could be transformed into each other. However, the finance department officials were still unwilling to show it to him for a closer look, using the excuse that the spiritual platform was expensive and rare, so Xia Fan had no choice but to give up. Unexpectedly, the Ministry of Industry has already started similar research and has produced impressive results.
"It's bumpy and easy to tip over." Mo Yun introduced in detail, "Its design purpose is to assist Qi's army in transportation and fighting. The bronze frame allows it to carry a huge weight without collapsing. It does not use traditional wheels. The four-legged structure is used so that it can cross mountains and ridges, and it can always keep up no matter where the frontier army goes."
"A bold idea." Xia Fan marveled.
"But it can't be stable for the time being." With the injection of Mo Yunjia's atmosphere, the four-legged beast's pace became much faster, but it also swayed obviously. This shaking comes from the inability of the limbs to maintain the same landing frequency. If it is faster and slower, it will tilt to the slower side, and its movements look rather stuck. "If the object was only as big as a model, it wouldn't hurt to be unstable. However, when it is enlarged to the size of a cow or horse, this shortcoming cannot be ignored."
Once the weight is added, the shaking effect will increase exponentially, let alone leaving the official road and climbing a rugged hillside.
Even because of this problem, there was an accident in the machine-building bureau where an overturned four-legged beast crushed a tester to death.
Of course, Mo Yun didn't think the other party could solve this problem.
Mechanism manufacturing is a highly professional manual work.
She brought it up here just to lower the princess's opinion of him step by step.
He couldn't solve the most difficult problem, so he would change it to an easier problem. Anyway, the Ministry of Works had accumulated dozens, if not hundreds, of problems. In this way, His Highness's view of him as "a master of everything" will change.
Mo Yun has already seen it.
The other party is by no means a charlatan in the traditional sense. He doesn't seem to value reputation that much, and he has a few unique skills in some fields. Although it was unclear where the princess's excessive belief in him came from, as long as Ning Wanjun was corrected, the situation would not be as bad as Qiuyue described.
-There should be no omniscient people in this world.
Mo Yun originally thought so.
However, the other party did not show the embarrassment or pretentious expression she expected.
"I guess even on flat ground, its joints often get stuck, right?" Xia Fan picked up the bronze four-legged beast and looked at it with admiration, once again marveling at the wisdom of the mechanism. This small model actually has a gear-like transmission structure.
She raised her eyebrows in surprise, "Why do you say that?"
"The wear of the gears is very serious, which means that it does not mesh perfectly. Because it wears quickly, it must be replaced frequently. In order to facilitate repair, these parts are not completely wrapped. If exposed to wind and sun, it will only become damaged. Faster."
This man...actually knows the art of mechanism
Mo Yun blinked, feeling a little dazed for a moment.
It has to be said that the problems pointed out by the other party are all old problems that the Machinery Bureau usually has troubled by being conservative. Most people will be dizzy just seeing the exquisite internal structure of this object. He can actually see the flaws at a glance
"This kind of problem... is simply unavoidable." She replied after a while.
"If you don't carve it by hand based on experience, but design the gear in advance using the involute principle, the two can mesh one by one, and you don't have to stare at its joints all day long."
"Involute? What is that?"
This confused Xia Fan - essentially, this is a concept of curve differential, which can be explained as common sense, but now it would be a bit embarrassing for him to list the formula in its entirety. Advanced mathematics can be completely forgotten after a few years, let alone that he has been here for more than ten years.
"Ahem, it's difficult to explain this in one or two sentences. You just need to understand that if there are no accidents, the gears designed according to this method will not get stuck or wear out due to their own problems, even if they run for several years."
Is there really such a way? Mo Yun was hesitant, why had she never heard anyone mention it? Whether it is a Mohist or a public loser, the fit of the toothed roller is extremely dependent on the skill of the caster, so that skilled craftsmen are heirlooms, and their experience and knowledge have also become heirlooms. The daughter’s exclusive secret.
But the other party thinks that carving based on experience is a bad thing
Before she could think about it, Xia Fan changed the subject, "But even if this flaw is solved, it can only improve the problem you mentioned. It is almost impossible to completely eradicate it - just like You can't really control a kite."
"Why?" Ning Wanjun asked curiously.
"The operator can only observe the pebbles and puddles under his feet, as well as the depressions and ridges on the ground, with his eyes. Not to mention the errors, even if a mistake occurs, it will be difficult for him to get feedback in the first time." Xia Fan paused. Dun said, "Similarly, if you can't fly as high as a kite, you can't feel the specific direction of the wind."
"Is that so?" The princess looked at Mo Yun.
The latter remained silent for a long time before slowly replying, "He... is right."
Not only is it right, it's spot on.
This is also the crux that has always been on her mind.
Everyone in the machine building bureau has been working hard on this for several months, but they still haven't found any clues. The real machine beast can indeed come and go freely on the flat ground, but once it is moved to a strange environment and the operator's proficiency drops, it is obviously at a loss.
The biggest problem with the machine beasts is the people themselves.
If this cannot be solved, it will always remain a model.
"Of course... As long as you change your thinking, it's not that difficult to deal with."
"Do you have any idea?" Mo Yun asked almost subconsciously.
"Yes. No." Xia Fan said calmly, "I said, if it still adopts the form of a four-legged beast, it is almost impossible to solve it."
If we follow the solution of another life, it will still be an extremely arduous task to maintain a dynamic balance of machinery. Relying on a large number of sensing probes and gyroscopes, plus electronic processors and continuously improved algorithms, we can barely achieve "stable stability" when affected by external forces. "Fall", this plan has no reference significance for the current mechanism.
Mo Yun was attracted by this answer, "You mean... the current form is the wrong choice? Then what should it look like?"
Xia Fan pointed at himself.
It took her a moment to react, "Human-shaped?"
"Not bad, and it's just enough for one person to be in it." Xia Fan nodded seriously. There is no gyroscope more exquisite than a human being. Even if the ground is slightly uneven, it can react immediately the moment you set foot. "Since you can't control the kite while standing on the ground, you might as well put yourself at high altitude and experience the changes of the wind for yourself."
Mo Yun felt like a flash of lightning in his mind!
Can people carry items on their backs
sure.
Can a person cross mountains and ridges
Not a problem.
So as Xia Fan said - what's wrong with making the machine beast into an armor-like shape and including the operator
A brand new idea suddenly appeared in front of her.
