After introducing this large piece of popular science content, Wu Hao finally breathed a sigh of relief, and then said to the crowd at the scene: "I know, everyone must be asking us." Since we have developed an intelligent bionic synchronous robotic arm, I also talked about electronic prosthetics and related technical content, so are we involved in this field?

The answer is yes, we have indeed set up such a dedicated R&D team for intelligent bionic electronic prosthetics. The age of this R&D team is very young, most of them are post-90s, and even some post-95s.

It is also a formal group of people that has made us a breakthrough in the technical field of intelligent bionic electronic prosthetics. Next, let's invite the technicians of our two R&D teams to bring our latest intelligent bionic electronic prosthetic equipment to give you a practical demonstration. ”

Bang Bang Bang ...... In a burst of applause, I saw three people walking up. Two of them were wearing Wu Hao's black T-shirts printed with the words Haoyu Technology, and they were pushing a cart with all kinds of equipment on it.

The other was dressed in a suit of athletic short-sleeves and shorts, but the most conspicuous thing was the national flag on his short-sleeved chest and his bare and mutilated right arm.

Wu Hao, who drank a saliva and rested for a while next to him, also walked to these people and introduced them with a smile to everyone: "First of all, I want you to introduce our national track and field athlete, Zhou Yongyong. He is 23 years old and is the world champion in the men's track and field event at the 2020 Paralympic Games.

As for his arm, he was severely burned after accidentally touching a wire when he was a child, and was eventually forced to amputate it. The sudden encounter made this teenager, who was originally going to school normally, fall into the bottom of his life all of a sudden, and even gave up on himself.

Fortunately, with the support of his family and teachers, he gradually regained his possession and began to learn physical education. In the end, after unremitting efforts, he not only successfully selected for the national team, but also won a very precious track and field championship on behalf of our country in the Paralympic Games. ”

Bang Bang Bang ...... Everyone present applauded the shy young man when they heard this. As for Zhou Yongyong, he smiled very shyly at everyone, and then bowed and thanked him.

Waiting for the applause to stop, Wu Haocai continued: "Although after hard work to overcome and adapt to training, the impact of missing an arm has gradually disappeared, and Zhou Yongyong has also won the Olympic championship.

But as you know, Paralympic champions are not as influential as Olympic champions, and track and field events are still not much noticed. So Yongyong's life hasn't changed much, and life still has to go on. Although he has long accepted this mutilated arm, it will still bring inconvenience to life.

More importantly, Yongyong is a person with strong self-esteem, and he hopes to be able to live and work like a normal person, rather than being treated differently or even discriminated against.

As for our research team, when conducting research experiments, we also need such an experimental tester with good physical fitness and relevant requirements.

After a series of screenings, we selected Zhou Yongyong, who lives in Anxi, to be our chief tester for the intelligent bionic electronic prosthesis. Of course, we also promise that after the successful development of our intelligent bionic electronic prosthetic is put into the market, we will equip such an intelligent bionic electronic prosthesis for free. ”

Bang Bang Bang ......

After the applause, Wu Hao motioned to the staff and Zhou Yongyong to start preparing, and he continued to introduce to everyone.

"As you can see, Zhou Yongyong belongs to the high amputation of his right arm, and basically the entire arm is missing, so the third method is not very practical. As for the first one, which is too cumbersome, it is not suitable for someone like him who is relatively sound in other aspects, let alone an athlete.

So we can only use the second method, which uses the motor bioelectric signals in the spinal nerves to control the intelligent bionic electronic prosthesis.

Because the entire right arm is missing, the intelligent bionic electronic prosthesis cannot be fixed on the residual limb, so we need to use other methods to install the entire intelligent bionic electronic prosthesis.

Here we are using the carrying method, using a special vest to wear and fix the robotic arm. ”

At the same time as Wu Hao's introduction, Zhou Yongyong also turned around and showed it to everyone. This resembles a semi-rigid black vest with many fulcrums on the right side of the vest, and several black metal brackets extending from the fulcrum to converge at the broken right arm, forming a mechanical interface.

A technician was seen picking up a white prosthetic leg from a black protective box. And on the top of this white prosthetic leg, there are many complex cables.

With the help of another technician, the technician jointly lifted the prosthetic limb to the interface of the mutilated position of Zhou Yongyong's right arm, and then aligned it and connected it.

Then one of the two technicians began to pick up the cable in earnest, and the other was attached to a laptop to debug.

"Because it's a human prosthesis, we have to be similar to a real prosthetic, not only in size, but also in weight, color, and realism. This makes it comfortable to wear and flexible to use.

Like the intelligent bionic electronic prosthetic that you see, it is actually customized by us with reference to the situation of Zhou Yongyong's left arm. To reduce weight and be durable, the entire arm is made of carbon fiber skeleton.

In the future, if needed, we will also attach an artificial bionic skin to the surface of this intelligent bionic electronic prosthesis. In this way, it can be consistent with a real arm in terms of appearance and even texture, and it is generally difficult to find if you don't touch it.

In the future, we are also planning to try to install tactile sensors on this intelligent bionic electronic prosthesis, so that the wearer can also enjoy the ability to touch and touch. ”

The onlookers nodded and praised when they heard his words, if the function is really the same, the shape and texture are the same, and they also have a sense of touch, then there is really no difference between this intelligent bionic electronic prosthetic and a real arm. If it can really be put on the market, it will save countless people with disabilities.

However, some people have expressed concern. Judging from what Wu Hao just said, what intelligent bionic is, what carbon fiber skeleton, and what artificial bionic skin and tactile sensors.

I'm afraid that the price of this intelligent bionic electronic prosthetic must be expensive, which is probably difficult to afford for many disabled people who have lost the ability to work.

Relying on corporate donations or relying on social charity, everyone couldn't help but shake their heads.
