Chapter 26 What's wrong with it?

```

Zhang Yuan opened the tablet and began to study it seriously.

Having studied mathematics for so long, perhaps he could tackle his father's article, add his own thoughts, and organize it into a paper.

The full-body movement-mirroring robot aimed to achieve the function that when a human made a move, the robot would perform an almost identical action, similar to the mechanical arm Ye Kaifu had just demonstrated.

Don't underestimate this function. It was the basis and premise of the "Power Exoskeleton"!

The Power Exoskeleton, also known as Power Armor, was currently a major research hotspot.

It wasn't just a weapon of war but could also be used for civilian purposes, such as replacing a space suit.

Due to the rapid development of nanomaterials, space suits were evolving towards simplicity and lightness. But one thing remained unavoidable, no matter what, space suits still had to carry a large oxygen tank and numerous life-support systems and communication systems.

The universe was dangerous. Whether it was a leak or a temperature loss, any small mistake could be fatal. These life-support systems had to be carried; missing any one of them was not an option.

Therefore, scientists proposed using the more cumbersome Power Armor to replace space suits. After all, with Power Armor, carrying more things wasn't a worry, and it was safer and more reliable. Even if thick armor got hit by fast-moving space debris, it wasn't a big deal.

Apart from replacing space suits, Power Armor could connect with humans through VR devices to perform dangerous and challenging tasks remotely, eliminating risks to human lives.

It was easy to talk about, but challenging to execute. Research on the Power Exoskeleton had been ongoing for a decade and was still in the experimental stage.

The main reason was still... immature technology.

For example, taking a balloon in hand and shaking it rapidly in all directions was simple for humans.

But for robots, it was no less than a herculean task!

Why? Robots lacked self-awareness; they had no idea how much force they used or how to shake it. These needed to be solved with mathematics.

Even the most sensitive sensors couldn't function as comprehensively as human skin. Gripping the balloon first required adjusting the cooperative pressure of the robotic hand—not too much, not too little—or it would burst. And shaking it rapidly was even more difficult.

Reportedly, a small company invented a patent for rapid pressure measurement ten years ago—the "MIA Pressure Sensing System." It's the glove Ye Kaifu used, earning billions in patent fees per year.

Of course, apart from cooperative pressure, there were many other challenges, such as joint drive force, body balance capability, control algorithms, etc. Such a complex project, with both hardware and software, running millions of lines of code, wasn't something Zhang Yuan could handle alone.

Therefore, he only wanted to solve one relatively key issue, then write a paper or patent. It would be even better if it could generate income for the Foundation.

"Let's write a paper!"

He got down to work, and a line of small text appeared on the screen.

"A High-Degree-of-Freedom Robot Kinematics Analysis Theory Based on Geometric Group Theory and Topology"...

The more research he did, the more profound and complex the ideas seemed.

His father's idea primarily focused on the complex kinematics of a "27-degree-of-freedom" robotic hand, which involved group theory, topology, and some knowledge of hypercomplex numbers, making it quite challenging to comprehend.

Even understanding the inspiration didn't mean he could smoothly write the whole paper.

His father only provided a general direction; Zhang Yuan had to fill in the large blanks himself.

Writing a paper was a painful task, like squeezing water from a sponge, with many details to address. Fully presenting inspiration wasn't easy.

Zhang Yuan's brain operated quickly, entering a highly focused state. He tried to sort out the overall thought process but was quickly hindered by numerous detailed problems.

Sometimes, seemingly "obvious" problems became obstacles when writing papers, becoming distinctly "non-obvious."

Zhang Yuan sighed deeply.

"With so many degrees of freedom in kinematics, coupled with strange algorithms, with my current ability, I could only understand, yet there really was no way to independently propose something. I wonder how my father thought it up..."

"Oh, Ye Kaifu, could you let me see your control program?"

"What program?" Ye Kaifu turned his head.

"The program for that mechanical hand."

"Oh, sure, no problem. This kind of programming, I'm actually not an expert, just self-taught..." Ye Kaifu said very cautiously.

Saying he wasn't an expert was really a modest statement.

Being able to write the related program already made him far more impressive than regular undergraduates!

Ye Kaifu looked at Zhang Yuan with a bit of a competitive spirit, wanting to know what level this new roommate was at.

Young people always had a sense of competition, especially these astronauts from all corners of the world, who were likely relatively outstanding.

Soon, the related program was sent to Zhang Yuan's computer.

Zhang Yuan pinched his nose as he looked at the program.

How to put it? Ye Kaifu indeed was an amateur, with poor programming habits...

Not mentioning the lack of comments in the code, the variable and function names were actually "a," "b," "c," "d," making it all foggy.

The downside to doing this was that, after a while, even the programmer himself couldn't determine what his code was supposed to do.

However, the algorithm content inside was much simpler than the idea his father proposed.

He quickly analyzed the general idea.

The entire glove was a very sensitive pressure sensor; the movement of human fingers caused pressure changes in the glove. Then, by processing this data with a certain algorithm, the specific direction of finger movements could be determined.

"And then transmitting the movement direction to the mechanical hand would make it follow suit."

This idea was quite intuitive and didn't have particularly good mathematical modeling, mainly relying on the intrinsic functions of the "MIA Pressure Sensor."

By the standards of real scientific evaluation, it would be just "ordinary."

Of course, Ye Kaifu was just an undergraduate, so one couldn't expect too much; no one expected an undergraduate to perform groundbreaking work.

Zhang Yuan carefully thought it over, analyzing many areas for improvement.

"Hey, anything wrong?" Ye Kaifu asked with concern, seeing the rich expression on Zhang Yuan's face, as he alternated between deep thought and frowning.

Yet he wondered to himself, in such a short time, could you really understand the entire algorithm?

It shouldn't be, after all, it took him ages to come up with it...

Anyway, my ex-girlfriend, and her male best friend, certainly couldn't understand it.

"Ah, nothing, just some parts..." Zhang Yuan turned back and, seeing none of Ye Kaifu's displeasure, continued, " ...a bit of a different opinion, don't mind, okay?"
