From all-round academic master to chief scientist

"Well...that's basically what it looks like."

Looking at the design drawings on the computer, Lin Xiao looked thoughtful.

Regarding the prosthetic limbs for monkeys, it is natural to design them first.

He had already named that monkey No. 1 Unlucky Monkey after that one—well, Lin Xiao now named that monkey No. 1.

This is also to prepare for the possible occurrence of No. 2, No. 3, etc. in the future.

He has already designed the model based on the proportions of Unlucky Monkey No. 1's right arm and left leg.

Then there is the issue of internal structure.

The legs are very simple, with not many joints and no need for toe joints to move. It is easy to make, but the arms are very troublesome. They need to install a lot of motors. How to perfectly accommodate these motors requires a lot of careful work. design.

Another thing is touch.

The feet do not need to be tactile, but the hands must be tactile. The tactile sensation on the hands is very important to people. For example, a novel writer basically needs to be able to type without looking at the keyboard when coding. How to do it without looking at the keyboard? Typing on a keyboard requires tactile feedback. Otherwise, your fingers will always touch accidentally, which is obviously a big problem for typing.

How to deal with the problem of tactile sensation is relatively simple. For the human hand, the most important tactile points are the fingertips and palms. When the time comes, just add pressure sensors directly to these key parts. It can be realized.

In addition to these problems, there is one last problem, which is energy.

That is the battery!

Lin Xiao remembered that in today's battery technology, lithium-ion batteries still occupy the main market. In terms of energy density, lithium-ion batteries are not enough in today's era, especially for prostheses. Of course, For this problem, you only need to use a removable battery structure. If you swap two batteries a day, the battery life can be basically maintained.

In addition, the safety of lithium-ion batteries is relatively low. Considering various cases of fires and even explosions, in order to avoid danger to people using these mechanical prostheses, it is also necessary to consider a device that can quickly Disassembled structures, even devices that automatically fall off.

Thinking of this, Lin Xiao shook his head and felt a little helpless, but there was no point thinking about it now.

At least the current safety of lithium-ion batteries is relatively high. Lithium-ion batteries from major manufacturers rarely have such dangerous accidents, and they conduct more careful screening when selecting batteries. Basically, This way you can avoid this problem.

All in all, these are the things that need to be paid attention to in the process of manufacturing this mechanical prosthesis.

"Forget it, let's forget about this nonsense for now. Let's build the thing first and then talk about it."

Thinking of this, Lin Xiao no longer struggled.

Then he went to the studio in the institute, which is mainly used to develop machinery.

This studio has machine tools, electric arc furnaces, and other equipment, such as polishing machines. It is very complete and is the dream workshop of any man who loves machinery.

And now that he has all the materials ready, only the final building work is left.

"Then let's get started!"

After putting on various protective gear, Lin Xiao began to work.

The first is to burn the aluminum alloy red. The aluminum alloy is relatively light and is more suitable as the main structure of the prosthesis. The most important thing is that it is also good in flexibility. Then it is covered with a layer of silicone to simulate skin. It will be very Perfect.

After the aluminum alloy burned red, Lin Xiao picked up the hammer and started hammering.

If outsiders saw Lin Xiao, a top mathematician and physicist, doing this kind of blacksmithing work, they would probably be surprised.

But for Lin Xiao, men always have the urge to make machines with their own hands.

In this way, he quickly built the shells and everything else according to the design drawings, and with the precision of his movements, the size difference between these shells and the ones he designed reached the level of 10 microns.

After finishing the shell, he prepared various wires and the PCB board he had designed before. This PCB board will be connected to the artificial nerve, and then transmit current to the artificial nerve and receive current from the artificial nerve.

This step is the connection between the external circuit and the circuit inside the human body, which is the most critical part. According to the nerve current interpretation book awarded by the system, bioelectricity and non-biological current will also achieve a perfect intersection!

…

Time passed quickly.

It took about ten more days, but Lin Xiao finally completed all the work.

A thick leg and a slightly thick arm. Compared with the legs and arms of Unlucky Monkey No. 1, they are relatively large. However, the large size is also to accommodate more batteries.

Of course, in addition to the legs and arms, there are two things that serve to connect the prosthetic limbs to the human body, just like the part where the Winter Soldier's mechanical arm in the Marvel movies is removed but still connected to his shoulder.

These two parts can facilitate the subsequent disassembly of the robotic arm, such as maintenance.

"Phew, finally done."

Picking up the arm, Lin Xiao looked at it, with a satisfied expression on his face.

Well, even if the Winter Soldier lost his mechanical arm and came to him, he would be able to build something similar.

"Okay, it's time for Unlucky Monkey No. 1 to experience what it feels like to be a cyberpunk monkey."

Lin Xiao's lips curled up, and then he took out his mobile phone and asked someone to make arrangements for the live animal laboratory in the biology laboratory and to transport his monkey there.

Then, he took his things and headed to the laboratory.

…

It’s the same laboratory that made artificial nerves last time.

After entering, Lin Xiao saw a monkey sitting in a familiar cage.

When the monkey saw him, he screamed "Zhi Zhi Zhi" with a look of fear on his face, as if shouting "Don't come over here."

Obviously, it has not forgotten the devil who gave it the knife.

Lin Xiao smiled, stepped forward and said, "Hey, don't be afraid, I'm not a devil."

"This time I want you to experience mechanical ascension. This is something that many of us humans want to experience."

"Don't be ungrateful."

But the monkey is still squeaking, joking, what does it know about mechanical ascension?

If it were a human being, Lin Xiao's current expression would undoubtedly look like those evil scientists who want to conduct human experiments.

Seeing the monkey's "uncooperative" look, Lin Xiao spread his hands and said, "Don't tell me? Then it seems like you don't have anything to say?"

So he didn't waste any time, walked forward, took out the anesthetic syringe, and then controlled the monkey and gave it an injection.

Then, the monkey showed an expression of despair and fell into a deep sleep.

Lin Xiao stopped talking nonsense and put it on the test table. Then he thought about the amputation and prosthetic surgery he had learned for so long, and then started to move.

First choice

This was not done with just one cut. Since it was a nerve surgery, he naturally needed to find a way to protect the internal nerves.

So he picked up a scalpel and slowly began to cut.

With his careful resection, he finally succeeded in keeping the monkey's brachial plexus intact.

The next step is to install the shoulder-arm connector, which requires the use of bone nails, which are directly inserted into the bones, and then the shoulder-arm connector is installed.

At this step, Lin Xiao took out the electric drill.

Probably, if the monkey wakes up suddenly now, he will probably regret waking up. Just think of the terrifying feeling when the doctor took out a hammer and hit it with a hammer when pulling out the wisdom teeth.

And the operation continued like this.

Until six hours later.

…

After installing the last mechanical leg, Lin Xiao finally wiped the sweat from his head and looked at the monkey in front of him.

The right arm and left leg, which were originally covered with hair, were now replaced by mechanical prostheses with a metallic appearance.

Especially the manipulator part, the metal joints are extremely clear, full of a strong sense of mechanics and science fiction.

Seeing this, Lin Xiao even suspected that they might not need to consider the silicone layer that imitates skin in the future. Looking at the shape of this robotic arm, who would be willing to replace it then?

No wonder the theme of mechanical ascension is so popular.

He could even take off his own arm and replace it with this robotic arm without excluding some people who want to be handsome rather than die.

He couldn't help but feel a little amazed at this thing, and then he shook his head and shook these speculations out of his head.

If there really are such crazy people, then there is nothing he can do. After all, he can't stop those who want to die.

Then, he put the monkey into the cage and waited for it to wake up to see if it could operate the two mechanical prostheses.

Time passed quickly, and after another hour, the effects of the anesthetic began to wear off.

Lin Xiao stared closely at the monkey's body.

First, the monkey moved his left hand. His left hand was fine, so it was not a big problem.

But then, Lin Xiao saw its right finger moving!

One of the mechanical fingers actually started shaking like that!

Lin Xiao's face immediately showed an expression of surprise.

Did you make it? !

At this time, the monkey's right arm also started to move!

Probably because it had been operated on, and after the anesthesia wore off, the monkey couldn't bear the pain, so it started to shake.

However, this scene has proven that the mechanical prosthesis created by Lin Xiao was successful!

Then, as time passed quickly, most of the anesthesia effect faded, and the monkey finally sat up.

At first, it covered its surgical site, trying to relieve the pain, but suddenly found that one of its familiar arms and legs had changed its appearance. It suddenly showed a fearful expression and began to jump up and down in the cage, but after a while Afterwards, he became quiet again, his fear turned into confusion and curiosity, and he began to touch his new arms and legs.

Seeing this scene, Lin Xiao also had a smile on his face.

Success!

At this moment, his phone suddenly rang.

It was Ma Gaoliang who called.

After the call was connected, Ma Gaoliang's laughter came from the other side: "Academician Lin, I have some good news for you. Guess what it is?"

Lin Xiao laughed and said: "Don't worry about your good news for now. Your good news is definitely not as good as my good news, so first guess, what is my news?"

I'll take a day off tomorrow, and that's it for today.
