Deep Space Fleet

Zhang Yuan opened the tablet and began studying carefully.

I have studied mathematics for so long, maybe I can read my father's article, add my own thoughts, and organize it into a dissertation.

Full-body action mapping robot. The function that we want to achieve is: when a human makes an action, the robot will make an almost identical action, similar to the robot arm Ye Kaifu just did.

Don't underestimate this feature, it is the foundation and premise of "Powered Exoskeleton"!

Dynamic exoskeleton, also known as dynamic armor, is a hot research topic.

It is not only a weapon of war, it can also be used for civilian use, such as directly replacing space suits.

Due to the booming development of nanomaterials, spacesuits are moving in the direction of simplicity and briskness. But one thing is inevitable: in any case, the space suit must carry a large oxygen cylinder, as well as a large number of life support systems and communication systems.

The universe is dangerous. No matter if it is leaking air or losing temperature, any mistake will kill people. These subsistence systems must also be carried, not least.

So the scientists envisage replacing the spacesuit with a more bulky guy called "Power Armor". Anyway, with the power armor, it is safer and more reliable to take more things without worrying. Even if the thick armor is hit by high-speed space junk, it is nothing.

In addition to replacing space suits, Powered Armor can be connected to humans through VR equipment, to perform dangerous and difficult tasks instead of humans, as long as humans can remotely control them, there is no longer danger to life.

It is easy to say and difficult to do. The research work on dynamic exoskeleton has been going on for ten years, and it is still in the experimental stage.

The main reason is that ... the technology is immature.

To give a simple example, hold a balloon with one hand, and then shake it up, down, left, and right at high speed. This action is extremely simple for humans.

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

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

No matter how sensitive a sensor is, it cannot be as versatile as human skin. To hold the balloon, you must first adjust the coordinated pressure of the manipulator. The force must not be too large or too small, otherwise it will be directly squeezed. 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 cooperative pressure, there are more and more difficult points, such as joint driving force, body balance ability, control algorithms, and so on. Such a complex project, all kinds of hardware and software, and millions of lines of code, can not be done by Zhang Yuan alone.

For some reason, he just wanted to solve one of the more critical issues and then write a thesis or patent. It would be better if it could bring income to the foundation.

"Come on, write a paper!"

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

A Kind of High-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 my thoughts are.

In Papa's idea, the main study is the complex kinematics of the "27-degree-of-freedom" manipulator, which contains group theory, topology, and some knowledge of super-complex numbers, which seems quite difficult.

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

Dad only gave a rough direction, and Zhang Yuan had to finish it.

Writing a dissertation is a painful task. It is like a sponge squeezing water. There are a lot of details to do. It is not easy to show the inspiration completely.

Zhang Yuan's brain moved quickly and entered 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 have become obstacles when writing a dissertation, becoming very "not obvious."

Zhang Yuan sighed deeply.

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

"Yes, Ye Kaifu, could you show me your control program?"

"What procedure?" Ye Kaifu turned his head.

"That's the program for that robot."

"Oh, okay, no problem. In fact, this programming, I am not very proficient, that is, from the wild road ..." Ye Kaifu said very carefully.

He said that he was not very proficient, but it was actually a modest statement.

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

Ye Yekai looked at Zhang Yuan richly and wanted to know what the level of this new roommate was.

Young people always have a kind of comparison mentality, especially those astronauts from all corners of the world.

Soon, related programs have been 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 good ...

There are no more comments in the code, so I won't say much. The names of various variables and functions turned out to be www.readwn.com.

The disadvantage of doing this is that if time goes by, the programmer himself may forget what his code is doing.

Alas, the content of the algorithm inside is much simpler than the idea proposed by Dad.

I soon analyzed the general idea.

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

然后 "Then pass the direction of motion to the robot and let it follow."

想法 This idea is very intuitive, and there is no particularly good mathematical modeling. It mainly relies on the functions of the "MIA pressure sensor".

If it is based on the true scientific evaluation criteria, it is the "sparse ordinary" grade.

Of course, Ye Kaifu is just an undergraduate student. He ca n’t ask too much. No one expects an undergraduate student to do amazing work.

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

"Dude, is there anything wrong?" Ye Kaifu saw Zhang Yuan's expression on his face, and after a while thinking and meditating, he frowned, and asked helplessly.

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

I should n’t, anyway, I also thought about it for a long time ...

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

"Ah, nothing, just some places ..." Zhang Yuan turned around and found Ye Kaifu had no unpleasant expression before proceeding to say: "... a bit different opinion, don't mind ha."
