In the virtual laboratory, with the assistance of Zhou Xiaozhi, Zhou Xing designed the direction joint of the robot joint. Pen, fun, and www.biquge.info

In order to make the robot's action 'soft', it is not enough to rely on the support of the drive system of the 'smart chip', but also to start from the hardware and design the structure of the robot from scratch.

The flexibility of human hands and feet is the result of the cooperation of joints, ligaments and muscles, while robots need to rely on gear nodes, universal joints, hydraulic pressures, and supporting levers,...... ,, , and other components are precisely coordinated, with intelligent chips to drive the body, so that the robot's movements become flexible, and the universal joint is a very important component.

Zhou Xing and Zhou Xiaozhi stood aside, carefully observing the robot with the same model as Baisha for experimental testing.

The robot walked, and the action of pouring water was much smoother than before, but Zhou Xing was still not very satisfied.

The robot's bulky body always stiffens its body when it moves, resulting in uncoordinated movements.

Seeing Zhou Xing shaking his head, Zhou Xing Xiaozhi, who was standing on the side, hurriedly said: "Boss, it is recommended to replace the universal joint with a lighter metal material, if it can be replaced together with the rotating shaft, otherwise, this situation will always exist." ”

"The axis of rotation is an important part of the robot, and the robot is directly load-bearing by 45% The weight of the universal joint is an important part connected to the axis of rotation, and the weight of the universal joint made of metal is too large, which directly affects the high-speed and high-dynamic performance of the robot; Zhou Xiaozhi proposed to Zhou Xing.

Zhou Xing frowned, the metal materials commonly used in the manufacture of robots are: stainless steel, aluminum alloy, alloy cast iron, sheet metal, etc., and there are many non-metallic materials, composite materials, classified by function, and can be divided into structural materials, coating materials, control materials,...... , etc., and so on, and so on.

The axis of rotation and the universal joint are the core components of the robot, and if the use of new materials can solve the problem of stiff robot movements, it is worth trying to develop.

After thinking clearly, Zhou Xing asked, "Xiaozhi, do you have any recommendations for the materials used for the rotating shaft and universal joint?"

"Boss, it is recommended to develop Ti alloys, multiphase nanoscale layered structural problems make Ti-based alloys have superior development potential, and can develop a Ti-based alloy with strength, high elasticity, lightweight, and machinability, which is suitable for manufacturing rotating shafts and universal joints. Zhou Xiaozhi suggested to Zhou Xing.

Hearing this, Zhou Xing frowned, and asked with a wry smile: "Is there no ready-made Ti-based alloy used?

Materials have always been the core of human beings used to manufacture various machines, components and equipment, is the cornerstone and milestone of human civilization, the world currently has 500,000 kinds of materials, more than 8 million kinds of synthetic compounds, the discovery, development and utilization of each new material, is a sign of the progress of human civilization, the influence is huge.

However, even if there is a particle environmental reaction chamber, which is almost cheating, it is not so simple to develop a new material, even if the development formula of Ti-based alloy materials is successfully found, the next step is to face the development of Ti-based alloy production process, vacuum melting environment, Ti-based alloy production process, and equipment,...... , etc., a whole set of projects down, and it is an extremely time-consuming project.

"Boss, Ash has screened! There are several Ti-based alloys suitable for manufacturing rotating shafts, however, according to your requirements for the number of nodes of the gimbal joint, Ash cannot screen suitable Ti-based alloys. Zhou Xiaozhi replied to Zhou Xingdao with a frowning face.

The number of nodes of the robot universal joint, related to the delicacy of the robot's action, the fewer the nodes, the more rigid the robot's action, the same manufacturing difficulty and cost price will also be reduced in a straight line, however, Zhou Xing has always been striving for perfection in his own development, there is a trace of progress, he will definitely try his best to overcome him, this is a habit he unconsciously developed after becoming a scientific researcher.

Zhou Xing settled down and ordered Zhou Xiaozhi: "Xiaozhi, screen the development formula of the new Ti-based alloy, and I will take it to the reaction room for testing." ”

"Okay, boss!" Zhou Xiaozhi replied happily.

Even if research is a monotonous and boring thing, for Zhou Xiaozhi, it is a very happy thing, because with the new research project, the longer Zhou Xing stays in the laboratory, the longer he accompanies it.

Soon, two waterfall-like data streams flew through Zhou Xiaozhi's dark eyes, and tens of thousands of Ti-based alloy element combinations were continuously simulated and checked to screen suitable Ti-based alloy development formulas.

Peking University, Department of Computer Management, Room 318 of the Women's Dormitory Building, the laughter of female students and the cry of begging for mercy were continuously transmitted.

"Okay, okay, I promised, you let me go! I promised but it didn't work! Don't spare it, 5555......." "Under the six 'devil's claws', Tang Xin begged for mercy.

At this moment, Room 318 was divided into two camps, and Tang Xin was unable to resist the 'three female bandits' when he was fighting alone.

"You little goblin, taking advantage of our unpreparedness, you actually got out of the house so quickly, and we've been worried about you, let's be honest and honest, isn't it already a step past now?" Guan Xiaoyu rode on Tang Xin's belly, pressed her hand with both hands, and asked.

"That's it, it's taken down by someone so soon! You're too useless, it's too easy to get what you have, men don't pay attention to it, if you are dumped by him in the future, see you cry there." Liu Zihui pinched Tang Xin's cheek and persuaded with a look of a passerby.

"Yes, Xiao Xin, Zhou Xing's status is not ordinary, he is handsome and rich, he controls a large company, there must be beautiful women around him, you have to be careful, don't suffer when the time comes!" Zhang Xiaofei persuaded with a worried face.

"You ,...... It's not what you think, we're just holding hands. Tang Xinqiao's face flushed, and she shook her head and argued.

"Hmph, do you just hold hands? Then why didn't you go home last night? You held hands all night! Do you treat me as a child?" Guan Xiaoyu glared at Tang Xin and said.

"I didn't see him last night, it's really my dad who came to the capital! I'm going to pick up my dad, it's true. Tang Xin smiled bitterly and said seriously.

"Hmm! really?" Guan Xiaoyu looked at Tang Xin's face and asked suspiciously.

"Uncle is coming to Beijing, why don't you take him to the school for a walk?" Zhang Xiaohui asked after believing Tang Xin's words.

"My dad came up to do something, and he came over when he was done. Tang Xin hurriedly replied.

"It's been a long time, it turned out to be an oolong!" Liu Zihui breathed a sigh of relief.

"If we didn't make it clear in advance, we were worried all night. A trace of embarrassment flashed on Guan Xiaoyu's face, and he hurriedly changed the topic and said, "When will that kid come over?"

"You come down first, I'll ask later. Tang Xin glanced at Guan Xiaoyu in shame and begged.

"Hehe!" Guan Xiaoyu smiled and turned over and got off Tang Xin.
