R&D personnel are actually not afraid of problems in their research, but they are most afraid of making mistakes in the direction of research and development, wasting several years of precious time, and having their research results 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 bring some things down."
Gu Qing waved his hand and went straight out.
Zhang Tianhao and Luo Yunjia looked at each other, and then quickly followed them.
Chu Ci looked at the person who had just spoken and said, "Zhou Wu, let's go and 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 he was assigned to this small company, he was still a little angry. He obviously did a good job on his project, but he was forced to be assigned by Professor Zhuang. It was a waste of time.
Arriving outside the laboratory, Gu Qing changed his clothes before going in.
He took out several installed robotic arms and castrated versions of neural signal connectors.
Zhang Tianhao was a big man holding two robotic arms, Chu Ci took the initiative to take a pile of materials for the honeycomb pneumatic network structure, and the others also took some things with their own hands.
Fortunately, the research laboratory building has a freight elevator, so Gu Qing is not too worried about someone accidentally breaking the material when going down the stairs.
Just like going to class, Teacher Gu took the teaching materials back to the classroom, and then Teacher Gu started today's teaching.
“The mechanical prosthesis of the arm mainly consists of three important components, the robotic arm, the brain-computer interface system module, and the intelligent feedback program chip.
Initially, I wanted to use machine learning to train a model to sense specific scenes through sensors and automatically complete corresponding actions. Let the prosthetic limb have its own 'knowledge'.
But later I discovered that this kind of 'cognition' could not handle complex body movements. Then when I was developing boundary markers to study artificial intelligence, I suddenly had the idea to develop an intelligent feedback program.
Equipped with a processing core with sufficient computing speed, it converts neural signals and brain waves into mechanically identifiable language control through the brain-computer interface system.
Come on, young man, let me experience what it feels 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 a resignation report this afternoon.
Because there are muscles made of a honeycomb pneumatic network structure, this robotic arm is much more bionic than the usual rigid robotic arms.
Zhou Wu was blindfolded, put on a brain-computer interface device, took off his shirt, and then 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 respected this senior who was once quite famous in the school.
He said softly: "Senior, I'm offended. I will try to tie it up as normal as possible."
"Don't act 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 for it."
Gu Qing's words made Zhang Tianhao's scalp numb unconsciously.
What he said seems to be life-threatening...
Zhou Wu, on the other hand, said calmly: "There are many uncontrollable factors in neural connections and brain wave control. If the robotic arm can really interact with me, then for the brain, this is a new organ, and the body can be stably controlled. Naturally it’s a problem.”
Gu Qing nodded. Although this man was a little arrogant, he was calm-minded and not a parallel import.
"You cooperate with Zhang Tianhao to tie him up, remember not to affect the blood flow, just control it so that he can't break free easily."
Although Gu Qing can command the robotic arm to stop working at any time through Xuanwu, this kind of backhand still needs to be hidden as much as possible without being exposed.
The installation part of the mechanical arm is under the ribs. The body bones can bear the weight and are easy to observe. The assembly is rather cumbersome. It is not like a movie where you just click it.
Gu Qing first felt the development of Zhou Wu's ribs, drew an area with a pen, then picked up a bottle of glue and began to apply the skin in this area.
"Although the nerve transmission is through special cables, the robotic arm, as a new limb, must fit closely with the body so that the brain can clearly realize its existence. Therefore, special glue is needed for pasting, otherwise it will be easy to stick on. If it cannot be removed, the user will have to lose a piece of skin."
After fitting the robotic arm, two researchers were asked to help fix it. Gu Qing pointed to the robotic arm, which was thicker than an ordinary person's arm, and explained: "If you want to perform ordinary movements such as twisting and grabbing, The robotic arm only requires a few motors and conduction modules.
But if you want to imitate a human arm, autonomously control the rotation of the arm, move the fingers flexibly, provide a grip strength of about 50 kilograms, and a pulling force of 100 kilograms, then the design and materials of the motor and the robotic arm will be a test.
The honeycomb pneumatic network structure is the muscle, the special steel serves as the skeleton, the nerve signal connector serves as the control nerve, and the intelligent feedback program can assist the brain wave for fine control. "
Chu Ci listened carefully on the side, looking at Zhou Wu's appearance, and unconsciously thought of the video of the Titan robot that the teacher asked him to watch some time ago.
He felt as if he had already found clues to the task assigned by the teacher.
But Zhou Wu, who was lying on the test table, didn't have so many thoughts, because he couldn't see now. He could only feel the coolness of the skin under his ribs, and then something was pressing against it.
While waiting for the glue to solidify, Gu Qing turned on the computer and fine-tuned the system settings. Time flew by while typing on the keyboard rapidly.
…
More than half an hour passed, and when the glue 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 robotic arm, so the neural signal conversion threshold, I set an average value obtained from previous experiments. Later I will turn on the switch of the brain-computer interface system, and the interaction of the data flow will Let your brain be uncomfortable for a short period of time. Then you need to calm down, then sense or deceive your brain, imagine that the mechanical arm under your ribs is your growing arm, and then start to manipulate it. When I say yes, Take off the blindfold again.”
Zhou Wu nodded to express his understanding.
"Then the experiment begins. The rest of the people stay three meters away from the test bench. Zhang Tianhao and Luo Yunjia, you two keep an eye on the power switch. If there is a problem, turn off the power immediately."
Gu Qing naturally cherishes his life. Even if the mechanical arm installed is a small toy version, he does not want to let himself be threatened by uncontrollable threats. After all, a gentleman does not stand under a dangerous wall.
