Three hours passed quietly, and Yin Tianhui slowly turned from the initial admiration into a state of anxiety. Yang Feng is still maintaining high-speed coding, and his hand is constantly tapping on the keyboard, changing fingering and key positions in order to type out special symbols in the programming language at the maximum speed.

Yin Tianhui looked at his watch from time to time: at this time, there were less than ten minutes left before the time of three hours, and Li Qiang couldn't sit still, stood up and patted Yang Feng on the shoulder, and said, "How long is it?", while Yang Feng looked at the computer screen intently, didn't even look back, and replied: "Right away, right away." ”

After hearing Yang Feng's words, Li Qiang didn't make a sound, obviously not believing Yang Feng's so-called "right away", and looked at Yang Feng's computer screen with a tangled demeanor, frowning. He stood there with his arms crossed, and his originally flat suit was strangled out one by one by this action, shaking left and right from time to time.

Yin Tianhui, on the other hand, sat there looking at his watch, letting out a sigh from time to time, looking at Yin Tianhui's expression, which seemed to regret his trust in Yang Feng just now.

Yang Feng was immersed in the world of coding, unable to extricate himself, and completely ignored Yin Tianhui and Li Qiang's movements.

As the minutes ticked by, Yin Tianhui's watch had already indicated that there were only two minutes left before the cut-off time, and he stood up and prepared to leave.

"That's it!", just as they were about to get up and leave, Yang Feng stood up from his chair, stretched his body, and said excitedly. The sound pierced the silence of the laboratory, and the stone hanging from the hearts of everyone present seemed to fall to the ground.

Yin Tianhui put on his glasses, slowly walked to Yang Feng's computer, tugged at his suit with both hands, and then sat down on the chair. Looking at the screen in front of me, the code written in C language is very clean and tidy, with lines of comments and lines of code complementing each other, showing the beauty of a piece of program logic.

Yang Feng walked straight to the machine and gently patted the shell of the machine with his hand, as if he was whispering something to this "friend". Then he opened the terminal computer on the machine, typed make install on the computer, and executed the compiled program.

Suddenly, the motor of the machine began to rotate, and the laser sensor and the ultrasonic sensor immediately entered the working state, and from the front of the machine, one laser beam after another could be seen, projected on the ground. The technician next to him saw that the machine began to move, so he picked up the black wide adhesive tape and began to paste it on the ground, so that he pasted it continuously for about 200 meters in the entire laboratory, and then nodded to Yang Feng to indicate that the experiment could be started.

Yang Feng entered the startup parameters on the terminal. The whole machine suddenly moved, and began to move forward along the wide black tape. The whole process is very smooth, and there is no mistracking or stopping in the middle of the machine.

"Not bad!", Yin Tianhui suddenly stood up and applauded Yang Feng with a smile. When the other personnel saw Yin Tianhui like this, they also applauded Yang Feng as if they were the wind. Sparse applause echoed in the lab. Yang Feng scratched his head embarrassedly and said, "Actually, I didn't do anything."

"Your programming ability is very strong, you are a rare talent!", Yin Tianhui said with a smile, and then said to the technicians: "You also input the program of the robotic arm." Integrate and compile with this lad's program."

As the technician enters the program into the machine and recompiles it, the machine's mechanical tentacles come to life. The two tentacles end in a tapered shape, and as soon as the machine is activated, the technician immediately evacuates the radius where the arm is working.

The machine, which could be half a human tall, began to move again. The technician placed a pile of parts along the way near the black plastic bag, and as the machine passed each pile, it would pick up the pile with a robotic arm and walk to the end of the black tape. At the end of the black tape, there is a platform on which an integrated circuit board is placed. On that integrated circuit board, there are no parts on it, except for the complete circuit. The machine walked to the front of the circuit board, "swish, brush, ......simmer", the mechanical arm began to continuously solder the parts on the circuit board, and after a while, a circuit board was soldered, although there are still some parts that are not soldered in place, but the finished circuit board is in very good condition.

"This technology is very high-end!", Yang Feng sighed.

Yin Tianhui said with a smile: "The technology of this welding part comes from Germany, and there is no domestic company that can achieve such precision." “

After Yang Feng heard this, he walked to the stationary machine, and the technicians did not stop it. Yang Feng took a closer look at the robotic arm. Sure enough, on the hinge of the robotic arm, I saw a line of small letters: "Made in Germany".

"Let's have a meal together tonight!", Yin Tianhui said happily, looked back at Yang Feng, and said to Yang Feng: "You are the protagonist of today." “

The group slowly walked out of the building with a smile, and along the way, Yin Tianhui and Yang Feng talked and laughed, constantly discussing various ideas about the development of robots and artificial intelligence. When Yang Feng saw that the sky outside the building had turned dark, he remembered that he had to go back to the dormitory tonight, so he said to Yin Tianhui: "Why don't we wait for another day."

And Li Qiang was afraid that Yin Tianhui and Yang Feng would have a good conversation and leak the matter of 100,000 yuan. For Li Qiang, Yang Feng is a very talented teenager, completely different from his previous impression, and he feels that this person will definitely be used in the future, so Li Qiang followed Yang Feng's meaning and said: "Yang Feng, you still have to go back to school tonight, right?

Yang Feng is a very practical person, it takes three hours to drive to school, he didn't want to trouble Li Qiang, and hurriedly said: "No need!

At this time, Yin Tianhui interjected: "Young man, where did you learn your technique?", Li Qiang was just about to speak, watching Yin Tianhui interject, so the corners of his mouth kept a stiff smile, his mouth was slightly open, and his Adam's apple was beating slightly, wanting to hear what Yin Tianhui and Yang Feng said.

"I mainly learn my technology from books, I bought some technical books and was more interested. “

- "And how long did it take you to learn robotics?"

"It took about a day, because I was not particularly familiar with the C language, so when I first started learning, it took more than three hours" to discuss how to learn new knowledge, which is Yang Feng's housekeeping skill

Yin Tianhui said with interest: "Is this true?"

"It's a fact," Yang Feng replied with a smile.
