Deep Space Planet Leader

Zhang Yuan turned on the tablet and began to study carefully.

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

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

Don't underestimate this function, it is the basis and premise of the "external power skeleton"!

The external skeleton of power, also known as power A, is a major research hotspot at present.

It is not only a war weapon, it can also be used for civilian use, for example: it can directly replace space suits.

Due to the vigorous development of nanomaterials, spacesuits are moving towards the direction of simplicity and lightness. But one thing is inevitable: In any case, space suits have 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 a leak or a loss of temperature, any mistake will kill people. These life-saving systems must also be carried, and none of them will work.

So the scientists envisaged that they would simply replace the spacesuit with the heavier guy "Power Armor". Anyway, with the power armor, no matter how many things you bring, it is safer and more reliable. Even if the thick armor is hit by high-speed space junk, it is nothing.

In addition to replacing spacesuits, Power Armor can connect to humans through VR devices, and do some dangerous and difficult tasks on behalf of humans. Humans only need to remotely control them, and there is no more mortal danger.

Easy to say but difficult to do. Skeleton’s research work has been going on for ten years and it is still in the experimental stage.

The main reason is...Immature technology.

For a simple example, hold a balloon with one hand, and then shake it up and down at high speed. This action cannot be simpler for humans.

But for robots, it is undoubtedly difficult to heavenly ascension!

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 the sensor is, it is impossible to be as comprehensive as human skin. To hold the balloon, you must first adjust the coordinated pressure of the manipulator. The force cannot be too large or too small, otherwise it will burst 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. Hundreds of millions.

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

Therefore, he just wanted to solve one of the more critical issues, and then write a paper or patent. It would be great if it could generate revenue for 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 you study, the more you read, the more profound and complicated the ideas are.

In my father’s idea, the main research is the complex kinematics of the "27 degrees of freedom" manipulator, which contains knowledge of group theory, topology, and some super-complex numbers. It seems quite Strenuous.

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

The old man only gave a general direction, and Zhang Yuan needed to complete the large amount of blank space behind.

Writing a paper is a painful thing, like a sponge squeezing water, there are a lot of details to do, it is not easy to fully show the inspiration.

Zhang Yuan's brain is spinning fast and entering a state of high concentration. He tried to clarify the whole idea, but soon got stuck with a lot of details.

Sometimes this is the case. Many seemingly "obvious" problems become a stumbling block when writing a thesis, and become very "unobvious".

Zhang Yuan sighed deeply.

"With so many degrees of freedom of kinematics, coupled with strange algorithms, with my current ability, I can only understand, and there is really no way to independently propose it. I don’t know how Dad came up with it. ..."

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

"What program?" Ye Kaifu turned his head.

"It's the program of the manipulator."

"Oh, yes, there is no problem. In fact, I am not very proficient in this kind of programming, which is from unorthodox..." Ye Kaifu said very cautiously.

To say that I am not very proficient is actually a modest way of saying it.

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

Ye Kai looked at Zhang Yuan vigorously, wanting to know how well this new roommate is.

Youngster always has a kind of comparison psychology, especially when these astronauts from all over the world are considered excellent.

Soon, the relevant programs have been posted to Zhang Yuan’s computer.

Zhang Yuan pinched his nose and watched these procedures.

How do you 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 actually "a", "b", "c" , "D", makes people feel like they are in the clouds.

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

However, the algorithm content inside is much simpler than the idea proposed by the father.

Soon, he analyzed the general idea.

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

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

This idea is very intuitive, and there is no particularly good mathematical modeling, and it mainly relies on "MIA pressure sensor" comes with the function.

If you follow the true scientific evaluation criteria, that is, the "normal" grade.

Of course, Ye Kaifu is only an undergraduate, and can’t ask for too much. No one expects undergraduates to be able to do heaven-shaking, earth-shattering jobs.

Zhang Yuan thought carefully and analyzed a lot of areas that could be improved.

"Dude, what's wrong?" Ye Kaifu saw Zhang Yuan's face with a rich expression, and he was thinking and frowns for a while, he couldn't help but asked with concern.

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

I shouldn’t. I thought about it for a long time before I figured it out...

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

"Ah, nothing, just some places..." Zhang Yuan turned around and found that Ye Kaifu didn't have any uncomfortable expressions, and then went on to say: "...Some different opinions, don't mind."
