"What is the key question?" Xia Fan also felt extremely curious, what did he see? An ancient remote-controlled toy! Capable means that it has a power source; being able to remotely control means that this power can be controlled by people!

As early as when he saw the Lingtai, he was already thinking about whether qi and strength could be transformed into each other, but the Ministry of Finance was engaged in using the Lingtai as an excuse for being expensive and rare, and he was always unwilling to take it out for him to take a closer look, so Xia Fan had to give up. Unexpectedly, the Ministry of Industry has already started similar research, and it has also come up with good results.

"It's bumpy and easy to tip. "It was designed to assist the Qiguo army in transportation and combat, and the bronze skeleton allowed it to carry huge weights without collapsing. The four-legged structure was adopted instead of traditional wheels so that it could climb mountains and mountains, and it would always be able to keep up with the frontier army wherever it went. ”

"Bold conception. Xia Fan was amazed.

"But it's not going to be consistent for the time being. Mo Yun increased the injection of qi, and the four-legged beast's pace was much faster, but it also obviously swayed. This shaking is due to the fact that the limbs are unable to maintain the same landing frequency, and the fast and slow side causes it to tilt towards the slower side, and its movement seems rather stuttering. "If it's the size of a model, it doesn't hurt to be unstable. However, when scaled to the extent of cattle and horses, this shortcoming cannot be ignored. ”

Once the weight goes up, the shaking effect will increase exponentially, not to mention leaving the official road and climbing the rugged hillside.

Even because of this problem, there has been an accident in the machine building bureau where an overturned four-legged beast crushed the tester to death.

Of course, Mo Yun didn't think that the other party could solve this problem.

Mechanism manufacturing is a highly professional manual work.

She brought it up here just to suppress the princess's evaluation of him step by step.

The most difficult thing he can't solve, so it's easier to change the problem, anyway, the problems accumulated by the Ministry of Industry are not hundreds, but there are dozens. In this way, His Highness's opinion of him "can do anything" will change.

Mo Yun had already seen it.

The other party is by no means a charlatan in the traditional sense, he doesn't seem to value his reputation so much, and he has a trick or two in some areas. Although it was not clear where the princess's excessive belief in him came from, as long as Ning Wanjun's opinion was corrected, the situation was not as bad as Qiu Yue described.

There should be no omniscient person in this world.

Mo Yun originally thought so.

However, the other party did not show the embarrassed or pretended deep expression she expected.

"I guess even on flat ground, it often has joint jamming failures, right?" Xia Fan picked up the bronze four-legged beast and looked at it fondly, once again admiring the wisdom of the machine-building bureau. In this small model, a gear-like transmission structure has appeared.

She raised an eyebrow in surprise, "Why do you say that?"

"The gear was very worn, which meant it didn't fit perfectly. Because it wears out quickly, it has to be replaced frequently, and in order to facilitate repair, these parts are not completely wrapped, and in the case of wind and sun, it will only deteriorate faster. ”

This man...... Do you know how to do tricks?

Mo Yun blinked, a little stunned for a moment.

I have to say that the problems pointed out by the other party are all the old problems that the Machinery Bureau is conservative and troubled on weekdays, and ordinary people are already dizzy just by seeing the exquisite internal structure of this thing, and he can actually see the defects at a glance?

"This kind of problem...... There's no way to avoid it. She waited a little while to reply.

"If you don't hand engrave it by experience, but design the gears in advance using the involute principle, you can bite one by one, and you don't have to stare at its joints all day. ”

"Involute? What's that?"

This stopped Xia Fan - in essence, this is a concept of curve differentiation, which can be said as common sense, but now it is a bit embarrassing to let him list the formulas completely. Advanced mathematics can be forgotten after a few years of loss, not to mention that he has been here for more than ten years.

"Ahem, this one or two sentences are difficult to explain clearly, you understand that the gear designed according to this method, if there is no accident, even if it runs for several years, it will not cause jamming and wear due to its own problems. ”

Is there really such a method? Mo Yun hesitated in her heart, why had she never heard anyone mention it? Whether it was the Mo family or the public loser, the degree of fit of the toothed roller was extremely dependent on the caster's technology, so that skilled craftsmen were family heirlooms, and even with their experience, it had become an exclusive secret for passing on men to women.

On the contrary, the other party thinks that engraving based on experience is a bad thing?

Without waiting for her to think about it, Xia Fan had already changed her mind at this time, "But even if this flaw is solved, it will only improve the problem you are talking about, and it is almost impossible to completely eradicate it—just like you can't really control a kite." ”

"Why?" Ning Wanjun said curiously.

"Pebbles and puddles under your feet, depressions and bulges in the ground, the operator can only observe with the eyes. Not to mention the errors, even if there is a mistake, it is difficult for him to get feedback in the first time. Xia Fan paused, "In the same way, 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 Moyun.

The latter was silent for a long time before slowly replying, "He...... That's right. ”

It's not just right, it's just hitting the nail on the head.

This is also the crux of her heart all along.

The Mechanical Bureau has been working hard for many months, but has never found any clue. The created trap beast can indeed come and go freely on the flat ground, but once it changes to an unfamiliar environment, the manipulator's proficiency decreases, and it is obviously out of place.

The biggest problem with the Trap Beast is the human being.

If it doesn't solve this problem, it will always be a model.

"Of course...... Just think differently, it's not that difficult to deal with. ”

"Do you have a way?" Mo Yun asked almost subconsciously.

"Yes. Nor did it. Xia Fan said calmly, "I said, if you still use the form of a four-legged beast, it will almost be solved." ”

If according to the solution of another life, it is still an extremely difficult task to keep the machine in dynamic equilibrium, relying on a large number of perception probes and gyroscopes, plus electronic processors and constantly improving algorithms, in order to barely achieve "steady fall" when affected by external forces, this set of solutions has no reference significance for the current machine manufacturing bureau.

Mo Yun was attracted by this answer, "You mean...... Is the current form the wrong choice? So what should it look like?"

Xia Fan pointed at himself.

It took her a moment to react, "Human-shaped?"

"Yes, and just enough for a person to put in it. Xia Fan nodded seriously. There is no more delicate gyroscope than a person, even if the ground is slightly uneven, the moment you land on it, you can react immediately. "Since you can't control the kite while standing on the ground, you can simply put yourself in the air and experience the change of the wind for yourself. ”

Mo Yun felt like a flash of lightning flashed in his mind!

Can a person carry an object?

Of course.

Can a man climb over a mountain?

Alone.

So as Xia Fan said, why not make the trap beast into an armor-like shape and include the manipulators?

A whole new idea suddenly appeared in front of her.
