Movie black technology
Chapter 70 The first experiment, live up to the original intention (don't add more for Qianliyi)
"Okay." Ma Zhen activated the prosthesis as required.
Then, the running indicator of the sensor cap lights up at the same time.
Chen Shen took out the notebook he carried with him, connected to the signal of the signal conversion device, and checked the running status of the whole machine.
"There is no problem with the connection between the brain control system and the prosthesis." He shut down the system and looked at Ma Zhen.
"This prosthesis has been tested before you come, and it works normally." Ma Zhendao.
Uncle Wu and his son at the back craned their necks and looked at them, curious about the prostheses on the table.
"Then let's start the test next." Chen Shen stepped aside and waved to Uncle Wu: "Uncle Wu, come here and sit down."
Uncle Wu hurried over and sat on a chair to straighten his waist, and his son followed him and draped his shoulders cautiously.
The tested prosthesis was fixed in the air on the bracket.
Seeing the tension between the two, Chen Shen put on a sensor cap for Uncle Wu: "Don't worry, this is just a simple test."
"Have I installed an EMG prosthesis before?"
"No, Uncle Wu has no long-term experience of using prosthetics."
Ma Zhen helped Uncle Wu to answer. He had asked various questions related to the experiment carefully before.
Uncle Wu in front of him had his entire right arm amputated due to an accident ten years ago. Later, due to family reasons, he has not installed a prosthesis such as electromyography or electric.
Around this seaside town, Uncle Wu is already the most suitable experimenter.
"That might be a little troublesome."
Chen Shen was mainly worried that the nerve signals related to Wu Shu and arm movement would be weakened.
If an EMG prosthesis was installed before, when using the prosthesis, nerve signals are required to issue instructions to generate EMG signals, this will not happen.
"Then what should I do now?" Uncle Wu turned around and asked.
Chen Shendao: "Try it first and see if you can read your nerve signals from Uncle Wu."
After speaking, he stepped aside, set aside the camera to shoot, went back to the computer and turned on the brain control system again.
"Uncle Wu can start. You can imagine that your right hand is moving, reaching out or spinning your wrist." Chen Shen said.
"it is good."
Uncle Wu responded and tried to do as required.
However, the prosthesis on the stent next to it did not respond...
Ma Zhenxin was cold for a while, then turned to look at Chen Shen.
Chen Shen was calm at this time, "Don't worry, this is a normal phenomenon. After all, his right arm has been missing for too long, and it is normal for the signal to be messy."
At this time, Uncle Wu stopped seeing that the prosthetic limb had not moved for a long time, and looked at Chen Shen nervously, not knowing what to do next.
Chen Shen smiled and gave a thumbs up: "Uncle Wu continues, the situation is normal now, and there will be a turnaround soon."
He glanced at it and the data on the computer showed that the corresponding neural signal is still being retrieved. Once retrieved once, the latter signal will be locked and can be connected at any time in the future.
Uncle Wu wiped the tense sweat on his forehead with his left hand, and simply closed his eyes and continued, while his son was also beside him cheering him with his eyes.
The people in the team looked nervously at Uncle Wu on the chair, and all the sleepiness just now was thrown to the horizon.
Ma Zhen snapped his fingers nervously on the side, and clicked...
Squeak~
suddenly.
There was a soft noise from the prosthesis.
I saw that the prosthetic limb that hadn't moved just now started, and the five fingers slowly tightened, making a fist.
Uncle Wu blankly looked at the prosthetic limb that was moving according to his wishes...
call!
The first reaction of everyone was a sigh of relief, and then they felt the joy and sense of accomplishment that came to their hearts.
Chen Shen looked at the computer screen, and it showed that a suspected fist signal had been matched. If there is an error, it can be corrected manually.
"Uncle Wu, did you just imagine that you were making a fist?" He asked Uncle Wu, who was staring at the prosthesis with his eyes in a daze.
"Oh!" Uncle Wu's eyes returned to focus, and tears gradually poured out, "Yes, yes, I was imagining that I was making a fist."
Chen Shen nodded, that is, there is no matching error in the signal.
"Go ahead," he said.
"Good!" Uncle Wu wiped away the unconscious tears with his left hand and wanted to continue the test, but the palms were all wet and the tears couldn't stop.
The person next to him immediately gave a tissue and asked Uncle Wu's son to help his father wipe the tears.
In this situation, the experiment obviously couldn't go on. Chen Shen smiled and shook his head, paused the test, and waited until the emotions of the father and son subsided before continuing.
The person next to him brought a cup of water to Shen Shen and Uncle Wu.
Ma Zhen grinned and couldn't close his mouth.
Not only him, everyone on the scene put a smile on their faces, even Chen Shen was no exception.
They feel that they are doing something meaningful and valuable.
The meaning and value of this matter are not only fed back to them, but can also be passed on to others through them.
Maybe they clenched their teeth a few years ago to make themselves and others smile like this.
After taking a sip of water, Uncle Wu walked over to Chen Shen and thanked him a lot, and he couldn't say enough.
Chen Shen quickly asked him to calm down and prepare for the next test.
"Good good!"
Uncle Wu sat back on the chair excitedly, feeling that his heartbeat had been accelerating and couldn't stop at all.
"Next, the second test is to match the wrist rotation and elbow flexion and extension." Chen Shen reminded.
Uncle Wu was passionate, and he was very cooperative in imagining these actions.
Soon, within a minute, the wrist rotation signal was detected and matched.
The mood of the people at the scene had calmed down, and they couldn't help but applaud.
After this, the elbow flexion and extension signals were quickly matched.
Seeing Uncle Wu happily controlling the prosthesis on the bracket as a child who got a new toy, everyone felt relieved, and there seemed to be a warm spring gushing from the bottom of my heart, spreading all over the body.
The original intention finally lived up to it!
The test was over at this point, but everyone looked at the joy of Uncle Wu, and no one could bear to disturb him.
It was not until half an hour later that Uncle Wu realized that there were fewer and fewer people around him, and realized that the experiment had stopped, and stopped embarrassingly.
"It's okay, Uncle Wu, you can continue to test, we collect more data." Ma Zhen said while sitting in front of the computer, as if analyzing the data.
In fact, he is now discussing with Chen Shen what needs to be improved in the prosthesis.
"There are still some movements that cannot be done with the current prostheses, and the execution time of the movements is still too long, and the fingers cannot be moved alone. Our first-generation products must achieve the fastest movement execution time within one second and allow multiple movements. Simultaneous execution."
"Hmm..." Chen Shen thought about it again: "Let's put it this way, in the first generation of products, I require users who use our prosthetics to be able to type on the keyboard with the same sensitivity as a normal person."
Hearing this goal, Ma Zhen thought about it again, and suddenly felt his scalp numb.
"You keep working hard, come to me if you have any questions!"
Chen Shen patted him on the shoulder, retracted the camera and left.
Of course, before leaving, he also asked Uncle Wu if he could put the video he just shot on the Internet, and he undoubtedly got an agreeable answer.
