Hehe, Wu Hao's face smiled when he saw this. Seeing him smile, Chu Tianyou and a group of scientific researchers next to him also smiled.

Wu Hao immediately tried to wave his hand with his right hand, and the right arm of the intelligent bionic synchronous robotic arm also waved his hand accordingly, which was very flexible.

"The synchronization and latency are pretty good this time." Wu Hao said with a smile when he saw this.

After Chu Tianyou heard his words, he introduced to him with a smile: "We have carried out a lot of optimization and upgrades on the system this time, which has greatly improved the computing speed of the system. And its moving members have also been optimized to make their control more light and flexible. ”

Wu Hao nodded when he heard this, and then immediately raised his left hand, and his left and right hands were spread. As for the two left and right robotic arms, just like him, the left and right manipulators are also opened.

Unlike the human hand, the manipulator has only three fingers. In addition to the 'thumb' that is relatively separate, there are also two 'fingers' that are juxtaposed together. The joint structure is the same as the structure of the human palm and fingers, and it is also very delicate and flexible.

However, these mechanical fingers are not exactly human, they are more like animal claws than hands.

Wu Hao deliberately moved his fingers, and found that the three fingers on the manipulator also moved with his fingers, which was very flexible. Among them, his thumb is also controlling the 'thumb' of the manipulator, and his index finger is controlling the mechanical finger that is closest to the thumb on the manipulator, or this is the 'index finger' of the manipulator.

His remaining three fingers, or ring finger and little finger, control the remaining finger on top of the arm alongside the index finger. It's just that the flexibility is a little worse than that of the thumb and index finger.

Of course, this is also in line with the physiology of the human body. In general, the thumb and index finger are the most flexible of our five fingers, while the remaining three fingers play an auxiliary gripping role.

In order to control the robotic arm more conveniently, the R&D team reduced the fingers of the robotic arm from five to three. Although it reduces the number of fingers, it does not hinder the normal function of the manipulator, and the operation is more convenient.

"You've chosen the three-finger solution in the end." Wu Hao smiled at Chu Tianyou.

Chu Tianyou nodded and replied: "This is the scheme we have jointly chosen after a series of tests and demonstrations, although the three fingers are two less than the five fingers, it does not affect the functionality of our overall manipulator." And the lack of two means that there are a lot less computing control programs, which will reduce the computing pressure on the system. ”

At this time, the young man who was about twenty-seven or eighteen years old standing next to Chu Tianyou also spoke: "First easy and then difficult, after all, this is our initial engineering prototype, and there are some problems that need us to slowly improve and optimize."

In fact, each of the five fingers of a person is very important and has its corresponding role. It's just that in order to speed up our current R&D progress, we have reduced it to three.

These three fingers can basically retain more than 85% of the functional movements and postures of our normal arms, so they have little impact on normal use. ”

The person who spoke was called Meng Hai, 29 years old this year, with a doctorate in microelectronics engineering from the University of Science and Technology, which is Wu Hao's senior brother and one of the talents he abducted from the University of Science and Technology.

Wu Hao shook his head with a smile and said, "I don't blame you, since it is the result of your joint discussion, of course I respect it." And at this stage, you have done a very good job of coming up with such an engineering prototype. Three fingers is three fingers, let's follow this first, and then upgrade and optimize when we have touched all the technologies in this area. ”

"Hehe, thanks to your help, Mr. Wu, it is precisely because of your participation and help and what valuable technical information has been provided that our research work can progress so quickly." Chu Tianyou slapped him on the back.

And Meng Hai also laughed: "That's right, especially in terms of information and data control system, it is really too helpful to us." ”

Wu Hao smiled and waved his hand: "This is nothing, it's our own project, I won't help you." ”

Saying that, Wu Hao tried to control it again, only to see him flip his palm, and then clench his fists. As for the two mechanical arms, they also flipped their palms like him, and then tightened their fingers and clenched tightly.

Wu Hao smiled when he saw this, and then put on a boxer's posture, raising his right hand and lowering his left hand slightly, and then tried to punch a few punches forward.

In order to exercise, he usually goes to some fitness classes and asks a personal trainer to teach him some fitness skills. In addition to some usual sports skills and equipment, the personal trainer also recommended boxing to him. It is said that proper boxing is good for exercising the coordination of the limbs, cardiopulmonary function, and being able to vent the stress on one's body, etc.

So Wu Hao often goes to boxing, and under the teaching of the coach, he still knows a little bit about these boxing moves.

Z, nourish...... Following his two-handed movements, the two robotic arms followed his example and threw a few straight punches in the air, and even learned from him to hit a left hook at the end.

Wu Hao, who had carefully observed the movements of the mechanical arm over and over again, couldn't help frowning when he saw this, and he immediately stopped and said: "The delay is still a little high, and in high-speed actions, the follow-up is a little poor." But the strength is okay, and you can feel the instantaneous explosiveness of its punches. ”

Hearing that Wu Hao was finding fault there, Chu Tianyou and Meng Hai couldn't help but glance at each other, and then laughed bitterly. Chu Tianyou smiled bitterly at Wu Hao: "No way, in the case of high-speed movement, our sensors capture more data in an instant, so it takes a certain amount of time to process." This is not usually felt under normal movements, and can only be felt when exercising at high speeds.

And in the end, it is a mechanical equipment, which is definitely not as flexible as our human arms, so there is a certain delay in movement. These two factors are added together, Mr. Wu, you will feel that there is a certain delay between the robotic arm and your movements, and the follow-up is a little poor. ”

Hearing this, Wu Hao swung his fist again and tried it, and then nodded. As Chu Tianyou said, it is indeed a problem in this regard.

Thinking of this, he couldn't help but ask, "Do you have any solutions to this aspect?" ”

Meng Hai shook his head: "Under normal circumstances, it will not have much impact, as for the delay and follow-up problems in the case of high-speed motion, we can only continue to optimize this from two aspects: hardware materials and system software." ”
