Technology: breaking the hegemony that monopolizes the world

R\u0026D personnel are actually not afraid of problems in research, but they are most afraid of making mistakes in the direction of research and development, wasting years of precious time in vain, and the research results are in vain, which is simply murdering their lives.

Of course, how could Gu Qing lead everyone into the ditch?

"Practice is the only criterion for testing truth. Come and follow me to the laboratory on the top floor to move some things down."

Gu Qing waved his hand and went straight out the door.

Zhang Tianhao and Luo Yunjia met each other's eyes, and followed quickly.

Chu Ci looked at the person who just spoke, and said, "Zhou Wu, let's go help too."

The researcher named Zhou Wu looked at Chu Ci who was exiled with him, and the hostility in his eyes calmed down a lot.

Although they were all assigned to this small company, he was still a little angry in his heart. It was a waste of time to be forced to be assigned by Professor Zhuang even though he had done a good job in the project.

When he came outside the laboratory, Gu Qing changed his clothes before going in.

He took out several assembled robotic arms and the castrated version of the nerve signal connector.

Zhang Tianhao was big and hugged two robotic arms, while Chu Ci took the initiative to take a bunch of materials for the honeycomb pneumatic network structure, and the others also took some things by hand.

Fortunately, the research building has a freight elevator, so Gu Qing is not too worried about someone going down the stairs and accidentally breaking the materials.

Just like going to class, I took the teaching materials back to the classroom, and Teacher Gu started today's teaching.

"The mechanical prosthesis of the arm is mainly composed of three important components, the mechanical arm, the brain-computer interface system module, and the intelligent feedback program chip.

Initially, I wanted to use machine learning to train the model to automatically complete the corresponding actions by sensing specific scenes through sensors. Let prosthetics have their own 'cognition'.

But later I found that this kind of "cognition" can't handle complex body movements. Then when I was developing Boundary to study artificial intelligence, I suddenly developed an intelligent feedback program.

Equipped with a processing core with sufficient computing speed, through the brain-computer interface system, the neural signals and brain waves are converted into language control for mechanical energy recognition.

Come on, boy, let you experience what it's like to have an extra hand. "

Zhou Wu nodded in agreement. He also wanted to experience it in practice. If it wasn't so advanced and practical, he would have prepared his resignation report this afternoon.

Because of the muscles made of honeycomb pneumatic network structure, this mechanical arm is much more bionic than the rigid mechanical arm you usually see.

Zhou Wu was blindfolded, put on a brain-computer interface device, took off his shirt, and lay down on the experimental table.

"This is a special material rope, tie him up." Gu Qing threw a bunch of ropes to Zhang Tianhao.

As a junior who graduated from Harbin Institute of Technology, Zhang Tianhao still respects this senior who was once quite famous in the school.

He said softly: "Senior, I've offended you, I'll try to tie it up as normal as possible."

"Don't be normal or abnormal. There are locks under the test bench. His limbs and torso must be fixed. Otherwise, if something goes wrong during the test, you will be responsible."

Gu Qing's words made Zhang Tianhao's scalp numb unconsciously.

It sounds like life is in danger...

On the contrary, Zhou Wu said calmly: "There are many uncontrollable factors in neural connection and brain wave control. If the mechanical arm can really interact with me, then for the brain, this is a newborn organ, and the body can be stably controlled. Naturally it's a problem."

Gu Qing nodded. Although this person is a bit arrogant, he has a calm mind and is not a parallel importer.

"You cooperate with Zhang Tianhao to tie it well, remember not to affect the blood flow, just control it so that he can't break free easily."

Although Gu Qing can order the mechanical arm to stop working through Xuanwu at any time, but this kind of backhand needs to be hidden as much as possible if it can not be exposed.

The installation part of the mechanical arm is under the ribs. The bones of the body can bear the weight and are easy to observe. It is rather cumbersome to assemble, and it is not as simple as a movie.

Gu Qing first touched the development of Zhou Wu's ribs, drew an area with a pen, then picked up a bottle of glue, and began to smear the skin of this area.

"Although the transmission of nerves is through special cables, as a new limb, the robotic arm must be closely attached to the body so that the brain can clearly realize its existence. Therefore, special glue is needed for pasting, otherwise it is easy to paste If you can’t take it off, the user will have to lose a piece of skin.”

After attaching the robotic arm, two researchers were asked to help fix it. Gu Qing pointed to the robotic arm which is thicker than ordinary people's arms, and explained: "If you want to do ordinary movements such as twisting and grasping, That robotic arm only needs a few motors and conduction modules.

However, if you want to imitate the human arm, autonomously control the rotation of the arm, flexibly dance the fingers, provide a grip force of about 50 kilograms, and a pulling force of 100 kilograms, then it is a test for the design and materials of the motor and the robotic arm.

The honeycomb pneumatic network structure is the muscle, the special steel is the bone, the nerve signal connector is the control nerve, and the intelligent feedback program can assist the brain wave to carry out fine control. "

Chu Ci listened carefully, looking at Zhou Wu's appearance, he unconsciously remembered the video of the Titan star robot that the teacher asked him to watch some time ago.

He felt that the task assigned by the teacher seemed to have found a clue.

But Zhou Wu, who was lying on the test bench, didn't have so many thoughts, because he couldn't see it now, he could only feel the coolness of the skin under his ribs, and then something was sticking to it.

While waiting for the glue to condense, Gu Qing turned on the computer and fine-tuned the system settings. The keyboard was tapped rapidly, and time passed by in a hurry.

...

More than half an hour passed, and after the glue had solidified and turned blue, Gu Qing asked the researchers to let go of the robotic arm.

"Because this is the first time your brain is connected to the mechanical arm, so the neural signal conversion threshold, I set an average value obtained in previous experiments, and I will turn on the switch of the brain-computer interface system later, and the interaction of the data flow will Let your brain have a short period of discomfort. When the time comes, you need to calm down, then perceive or deceive your brain, imagine that the mechanical arm under your ribs is your growing arm, and then start manipulating it. When I say yes, Take off the blindfold again."

Zhou Wu nodded, expressing his understanding.

"Then the experiment will start. The rest of the personnel will be three meters away from the test bed. Zhang Tianhao and Luo Yunjia, you two should watch the power switch. If there is a problem, immediately turn off the power."

Gu Qing naturally cherishes his life, even if the robotic arm installed is a small toy version, he does not want to be threatened by uncontrollable, after all, a gentleman does not stand under a dangerous wall.
