Deep Space Fleet

Zhang Yuan turned on the tablet computer and began to study hard.

After studying mathematics for so long, maybe I can study my father's article, add my own thoughts, and organize it into a paper.

The function of the whole-body motion-mapping robot is: when a human makes an action, the robot will make an almost identical action, similar to the robotic arm that Ye Kaifu just made.

Don't underestimate this function, it is the basis and premise of the "powered exoskeleton"!

Powered exoskeleton, also known as power armor, is a major research hotspot at present.

It is not only a weapon of war, but also can be used for civilian purposes, for example: directly replacing space suits.

Due to the vigorous development of nanomaterials, spacesuits are developing in a simple and light direction. But one thing is unavoidable: In any case, the spacesuit has to carry a large oxygen cylinder, as well as a large number of life support systems and communication systems.

The universe is dangerous, whether it is air leakage or temperature loss, any mistake will kill people. These life support systems must also be carried, and nothing less will do.

So scientists envisioned simply replacing the spacesuit with a more cumbersome guy called "Power Armor". Anyway, with Power Armor, you don’t have to worry about carrying more things, and it’s safer and more reliable. Even if the thick armor is hit by high-speed space junk, it's nothing.

In addition to replacing spacesuits, Power Armor can be connected to humans through VR devices to replace humans to do some dangerous and difficult work. Humans only need to control it remotely, and there is no longer any danger to their lives.

Easier said than done, the research on powered exoskeletons has been going on for ten years and is still in the experimental stage.

The main reason is still... immature technology.

To give a simple example, holding a balloon with one hand, and then shaking it up and down, left and right at high speed, this action could not be simpler for humans.

But for robots, it is undoubtedly difficult to reach the sky!

Why? The robot has no self-awareness. It doesn't know how much force it uses or how to shake it. All of these need to be solved by mathematics.

No matter how sensitive a sensor is, it is impossible for it to be as fully functional as human skin. To hold the balloon, you must first adjust the cooperative pressure of the manipulator. The strength should not be too large or too small, otherwise it will explode directly. It is even more difficult to shake at high speed.

It is said that 10 years ago, a small company invented a patent for rapid pressure measurement - "MIA pressure sensing system", which is the leather glove used by Ye Kaifu, and earned hundreds of millions of patent fees a year.

Of course, in addition to collaborative pressure, there are more difficulties, such as joint driving force, body balance ability, control algorithm and so on. Such a complicated project, all kinds of hardware and software, and millions of lines of code, cannot be done by Zhang Yuan alone.

Therefore, he just wants to solve one of the more critical problems, and then write a paper or patent. It would be great if it can bring income to the foundation.

"Come on, write a paper!"

Just do it, and a line of small characters appears on the screen.

"A high-degree-of-freedom robot kinematics analysis theory based on geometric group theory and topology"...

The more I study, the more I read, the more profound and complicated the thoughts are.

In Dad's idea, the main research is the complex kinematics of the "27 degrees of freedom" manipulator, which contains group theory, topology, and some knowledge of hypercomplex numbers, which seems to be quite difficult.

Even if you understand the inspiration in it, it doesn't mean that the whole paper will come out smoothly.

The father only gave a general direction, and Zhang Yuan had to complete a lot of blanks behind.

Writing a thesis is a painful thing, just like squeezing water from a sponge. There are a lot of details to be done, and it is not easy to fully express the inspiration.

Zhang Yuan's brain was running fast, entering a state of high concentration. He tried to sort out the whole idea, but soon got stuck with a lot of details.

Sometimes this is the case. Many seemingly "obvious" problems become obstacles when writing a thesis, and become very "not obvious".

Zhang Yuan sighed deeply.

"The kinematics with so many degrees of freedom, plus the strange algorithm, with my current ability, I can only understand it, and I really can't propose it independently. I don't know how Dad came up with it..."

"By the way, Ye Kaifu, can you show me your control program?"

"What procedure?" Ye Kaifu turned his head.

"It's the program of the robot."

"Oh, okay, there's no problem. Actually, I'm not very proficient in this kind of programming, that is, I was born in Ye Luzi..." Ye Kaifu said very cautiously.

To say I'm not very proficient is actually an understatement.

Being able to compile related programs is already much better than normal undergraduates!

Ye Kaifu looked at Zhang Yuan competitively, wanting to know how well this new roommate is doing.

Young people always have a kind of comparison mentality, especially when these astronauts from all over the world are likely to be good.

Soon, the relevant programs were sent to Zhang Yuan's computer.

Zhang Yuan pinched his nose and looked at these programs.

how to say? Ye Kaifu is indeed a layman, and his programming habits are not very good...

There are no comments in the code, so I won't say much. The names of various variables and functions are "a", "b", "c", and "d", which makes people confused.

The disadvantage of this is that if it takes a long time, maybe the programmer himself will forget what his code is doing.

However, the content of the algorithm inside is much simpler than the idea proposed by the old man.

Soon, he analyzed the general idea.

The whole leather glove is a very sensitive pressure sensor, and the movement of human fingers will cause the pressure of the leather glove to change. Therefore, after processing these data through a certain algorithm, the specific movement direction of the finger can be obtained.

"Then pass the motion direction to the manipulator, so that it can follow the motion."

This idea is very intuitive, and there is no particularly good mathematical modeling, mainly relying on the built-in functions of the "MIA pressure sensor".

According to the real scientific evaluation criteria, it is the "common and ordinary" level.

Of course, Ye Kaifu is just an undergraduate student, so he can't ask too much. No one expects undergraduate students to do earth-shattering work.

Zhang Yuan thought about it carefully and analyzed a lot of things that could be improved.

"Brother, is there something wrong?" Ye Kaifu couldn't help asking with concern when he saw Zhang Yuan's rich expression, thinking hard for a while, and frowning for a while.

But he muttered in his heart, can you really understand the whole algorithm in such a short time?

It shouldn't be, anyway, I thought about it for a long time before I figured it out...

Anyway, my ex-girlfriend and her boyfriend must not understand.

"Ah, it's nothing, it's just that there are some places..." Zhang Yuan turned around and found that Ye Kaifu didn't show any displeasure, so he continued: "...I have a little different opinion, don't mind it."
