Reborn Troops

Zhou Wanwan was not discouraged. She thought for a while and said, "Teacher, if we mix pearl powder with resin,

How about making a material that imitates pearls? This way, it retains the luster of pearls while increasing their toughness. "

Master Zhongshan nodded and said, "This is a good idea. However, the transparency of the resin may affect the luster of the pearls. You have to make a sample first."

Zhou Wanwan immediately said: "Then let's go find materials and make a sample now!"

Master Zhongshan smiled and waved his hand: "Don't be impatient, design is something that requires patience.

Go back and think about it carefully, and perfect the details. Come back to me tomorrow and we will discuss it together."

Zhou Wanwan and Qianqian looked at each other and said in unison, "Okay!"

The next morning, Zhou Wanwan and Qianqian came to Master Zhongshan's studio again with the revised design drawings.

This time, they not only drew the appearance of Pearl Doraemon, but also marked the design of the internal mechanical structure in detail.

Master Zhongshan looked at the design carefully and nodded with satisfaction:

"Yes, this design is much more detailed than yesterday's. But have you considered the action design of Doraemon?

It is not enough for the dragonfly to just turn. If the robot can make some simple movements, such as nodding and waving, the effect will be better. "

Zhou Wanwan's eyes lit up: "Yes! We can design a simple mechanical device for Doraemon so that it can make corresponding movements as the bamboo dragonfly turns!"

Qian Qian clapped her hands excitedly: "Isn't that even cooler? Pearl Doraemon with a bamboo dragonfly with crystal wings, and it can move, it's awesome!"

Master Zhongshan smiled, picked up the pen and drew a few strokes on the design:

“You can add a small motor here and control the movements of the Doraemon through gear transmission.

However, this will increase the complexity of the entire design, so you have to be mentally prepared."

Zhou Wanwan nodded: "Teacher, we are not afraid of complexity! As long as we can achieve the desired effect, we are willing to try no matter how difficult it is!"

Master Zhongshan gave her an approving look and said, "Okay, let's get started."

In the next few days, Zhou Wanwan and Qianqian spent almost every day in Master Zhongshan's studio.

While learning the design of mechanical structures, they also tried to make imitation pearl materials using pearl powder and resin.

Master Zhongshan patiently guided us and offered suggestions for improvement from time to time.

However, things did not go as smoothly as expected. When making imitation pearl materials, they found that the transparency of the resin did affect the luster of the pearls.

After trying several times, none of them worked. Zhou Wanwan was a little frustrated, but Master Zhongshan comforted her:

"Don't worry. Design is a process of trial and error. You can try adding some fluorescent powder to the resin to see if it can enhance the gloss."

Zhou Wanwan followed Master Zhongshan's advice and re-adjusted the materials. This time, the gloss of the imitation pearls was much better, almost the same as real pearls.

Just as they were about to start making the shell of Doraemon,

Qianqian suddenly asked a question: "Wanwan, did we forget to consider the weight of Doraemon?

If the outer shell is made of imitation pearl material and there are mechanical devices inside, will the whole Doraemon be too heavy for the bamboo dragonfly to carry? "

Zhou Wanwan was stunned for a moment, then frowned: "Yes, this is indeed a problem..."

Master Zhongshan came over, looked at their design drawings, and said:

“You can make some optimizations on the internal structure to reduce the weight as much as possible.

For example, using lightweight alloys to replace ordinary metals, or reducing some unnecessary mechanical devices. "

Zhou Wanwan nodded: "Okay, let's readjust the design."

After several days of hard work, they finally completed the preliminary design of Pearl Doraemon.

The outer shell is made of imitation pearl material, the interior uses a lightweight alloy frame, and the mechanical device has also been optimized, so the overall weight is controlled within a reasonable range.

In the next few days, they started making Pearl Doraemon.

However, due to lack of experience, they encountered many problems during the production process.

The outer shell was not spliced ​​tightly enough, and the debugging of the mechanical device was not smooth. There was even one time when the motor suddenly failed and almost burned out the entire Doraemon.
