Military Technology

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

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

"Synchronization and delay are pretty good this time." Wu Hao said with a smile upon seeing this.

After hearing what he said, Chu Tianyou smiled and introduced to him: "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. We have also optimized its moving components to make it control More lightweight and flexible."

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

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

However, these mechanical fingers are not exactly the same as human ones. Rather than saying that they are hands, they are more like animal claws.

Wu Hao moved his fingers deliberately, 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 closest to the thumb on the manipulator, or this is the 'index finger' of the manipulator.

And his remaining three fingers, or the ring finger and the little finger, control the remaining finger on the mechanical arm that is juxtaposed with the index finger. It's just that the flexibility is relatively poor compared to the thumb and index finger.

Of course, this is also in line with the physiological structure of the human body. Under normal circumstances, among our five fingers, the thumb and index finger are the most flexible, while the remaining three fingers play a role in assisting grasping.

In order to control the robotic arm more conveniently, the R\u0026D team reduced the fingers of the robotic arm from five to three. Although two fingers are reduced, it does not hinder the normal function of the manipulator, and the operation is more convenient.

"You finally chose the three-finger plan." Wu Hao smiled at Chu Tianyou.

Chu Tianyou nodded and replied: "This is the plan we have jointly chosen after a series of tests and demonstrations. Although the third finger is two less than the fifth finger, it does not affect the functionality of our overall manipulator. And two less, It means that a lot of calculation and control programs are needed, and the calculation pressure on the system will be relatively reduced."

At this time, the young man standing next to Chu Tianyou, who was about 27 or 18 years old, also said: "First easy and then difficult. After all, this is our preliminary engineering prototype. There are some problems that we need to solve slowly." Improved optimization.

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

These three fingers can basically retain more than 85% of the functional movements of our normal arms, so normal use has little effect. "

The person who spoke was Meng Hai, twenty-nine years old this year, a Ph.D. majoring in Microelectronics Engineering from the University of Science and Technology.

Wu Hao shook his head with a smile and said: "I don't mean to blame you. Since it is the result of your joint discussion, I certainly respect it. And at this stage, you can come up with such a prototype, and you have done a very good job. Three Three fingers, let’s follow this first, and then upgrade and optimize after we have mastered the technology in this area.”

"Hehe, thank you Mr. Wu for your help.

It is precisely because of your participation and help and the precious technical information provided that our research work can progress so quickly. "Chu Tianyou flattered him a little.

And Meng Hai also laughed and said, "That's right, especially in terms of information and data control systems, you have really helped us a lot."

Wu Hao waved his hand with a smile and said: "It's nothing, it's all our own project, if I don't help you, who will I help?"

As Wu Hao tried to control it again, he turned his palm over and clenched his fist. As for the two mechanical arms, they turned over their palms like him, then tightened their fingers and clenched them tightly.

Wu Hao smiled when he saw this, and then put on a boxer's stance, raised his right hand, raised his left hand slightly, and then tried to punch a few times towards the front.

In order to exercise, he usually goes to some fitness classes, and asks a private 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 conducive to exercising the coordination of the limbs, cardiopulmonary function, and being able to vent the pressure on one's body, etc.

So Wu Hao often goes to boxing too. Under the teaching of the coach, he still has a little understanding of these boxing moves.

Zi, Zi... Following his movements, the two mechanical arms imitated his appearance and hit a few straight punches in the air, and even imitated him to hit a left uppercut at the end.

Wu Hao, who punched and observed the movement of the mechanical arm carefully, frowned when he saw this, he stopped immediately and said: "The delay is still a bit high, and the followability is a little bit poor in high-speed movements. But the strength is not bad, I can feel the instant explosiveness when it punches."

Hearing Wu Hao's fault-finding, Chu Tianyou and Meng Hai couldn't help but looked at each other, and then they all laughed wryly. Chu Tianyou smiled wryly at Wu Hao: "There is no way. In the case of high-speed movement, our sensors capture a lot of data instantly, so it takes a certain amount of time to process it. You can't feel this in normal movements. It can only be felt in high-speed sports.

And after all, it is a mechanical device, it is definitely not as flexible as our human arms, so there is a certain delay in movement. When these two factors are added together, Mr. Wu, you will feel that there is a certain delay between the robot arm and your movements, and the followability is somewhat poor. "

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

Thinking of this, he couldn't help asking: "About this aspect, do you have any solutions at present?"

Meng Hai shook his head: "Under normal circumstances, it won't have much impact. As for the delay and follow-up problems under high-speed motion, we can only continue to optimize from the two aspects of hardware materials and system software. "
