Li Guocheng re-copied a robot's algorithm on the Kunpeng server number 1 to manage four servers, and named it Xiaosan.

The name of an engineering student is so casual and down-to-earth.

Through the computer in the laboratory, connect to the Kunpeng server, and load the source code and data of Xiao Er to another robot controller again. Of course, this new robot is Xiao Er.

In order to distinguish, there is a number on the chest of each robot, the minor one is 001, and the minor two is 002.

In the position close to Xiao Yi, a space was once again divided, and the same order as Xiao Yi was given. Let them accumulate data on their own.

In order to facilitate the robot to hide itself, Li Guocheng specially designed two large storage boxes, put them under the experimental table, and the robot issued instructions to automatically open and close the side door of the storage box.

Each one has a quick storage plug and data interface, when the robot battery is out of power, enter the storage box, one of the tentacles will extend a plug in the palm of the hand, insert the fast storage interface, store power, and rest at the same time.

Another plug protruding from the palm of the tentacle connects to the data interface, which can exchange data with the Kunpeng server, upload historical data, and use the computing power of the four servers to analyze and simulate.

After dealing with the robot, Li Guocheng thought of a very good thing, that is, a drone.

After modeling and analysis, he chose the easiest to control 4-axis flying drone.

The 4 motors of the droneBased on the motor structure of the robot, he redesigned a 12V brushless DC motor with low power and small volume, which is very suitable for the use of drones.

The material of the double-bladed propeller was selected in the database as a plastic formula with high toughness, because it was not in stock, so it was too lazy to wait, and it was formulated directly in the laboratory.

With enough special plastic, he carved it by hand according to the model in his mind.

A flurry of plastic chips flew and in less than 2 hours, a lightweight 4-axis drone frame was sculpted.

After 1 month, all the accessories are ready, including the microcontroller board.

Li Guocheng watched Xiao Yi and Xiao Er move and jump in a radius of 2 meters each, while assembling the drone.

At this time, the cable on their back has been removed, and they are powered entirely by batteries. When fully charged, it can last for 2 hours.

According to the simulation, if they sprint with all their might, they can reach a short-term speed of 20 km/h, but the endurance is less than 1 hour.

Of course, this sprint mode has not had a chance to experiment yet, and now the focus is on learning smooth movements.

As it is true of artificial intelligence, they are now able to do some difficult actions such as jumping and flipping, and they can already ensure that they do not fall. Others, such as parallel movement, have been very smooth.

The next step was to find a venue for them to practice sprinting and jumping, which was the challenge they had to face. The requirements for the movement curve will also be more demanding.

At that point, the motion curves need to be more finely divided, and each small segment needs to be more complex to control.

The synchronization and coordination of 3 motors per leg and 18 motors on 6 legs can be a very big challenge.

The idea is to first complex, then optimize. Finally, the fuzzy neural network algorithm is used to reduce the load of computing power and memory.

And these, whether it is telekinesis or simulation algorithms, are difficult to process such a long time and long distance complex data.

It seems that it is necessary to prepare some robot bodies, and when it comes to complex movements, wear and tear is inevitable.

Li Guocheng thought of this and looked at the accessories in his hand, smiled self-deprecatingly, and sighed how he has always been distracted recently.

The only explanation is that he has made the old mistake again, he has too many things to worry about, and he is prone to impatience, and secretly warns himself in his heart.

When the design of the helicopter is completed, you have to take a vacation for yourself and go abroad to relax.

"Hey, why are your thoughts running away again", he hurriedly refocused his attention on the accessory in his hand.

Soon, a burst of lightning five in a row, a small 4-axis drone was assembled.

In order to reduce the difficulty of control and improve the self-control ability of the drone, Li Guocheng not only adaptively adjusted the flight control program, but also specially developed a miniature semiconductor gyroscope.

The highlight of this gyroscope is the miniature, the design principle simulates the principle of a mechanical gyroscope, and the piezoelectric ceramic is placed on a fast mass, plus the piezoelectric acquisition circuit is a very ingenious design.

From the appearance, it can only be seen that this is a device in an SO-8 standard package.

X, Y, and Z three-axis data are transmitted through the serial port.

In order to be technologically advanced, he is not ready to apply for a patent for this miniature gyroscope.

In the previous month, he was mainly manufacturing this kind of miniature gyroscope, because the installation accuracy was too high, even he had to confirm and test repeatedly before completing the package.

If mass production is to be achieved in the future, a dedicated precision measurement and assembly platform is necessary.

Hey, so basic industry is the foundation of scientific and technological innovation, without this platform, no matter how good the design is, it is a castle in the air.

With this foundation, it is like having a fertile field, which can produce all kinds of producers, fruits and flowers. Without it, it's a tech desert.

Li Guocheng rubbed his temples, feeling that there were too many things to do next, and this platform was not the most urgent thing, there were more things to worry about.

The drones are all assembled and all static tests have been completed, and the next step is to officially take off.

Li Guocheng did not relent, he handed over the control of the remote control to Xiaoyi.

The command given is to take off slowly and, according to the flight attitude, record data for adjusting control parameters and 4-axis synchronization logic.

As expected, it flew only 10 centimeters above the ground and fell to the side.

Xiaoyi stopped flying, connected with the flight control chip of the drone, read the flight data, calculated the same way, gave an adjustment plan, and after getting Li Guocheng's confirmation, the flight control parameters were modified.

Then take off again, so repeated operations hundreds of times, and finally meet Li Guocheng's requirements, Xiaoyi issued a take-off command, the drone can be automatically controlled to fly smoothly to a position of 1 meter high, waiting for the next command.

In the process of adjusting the parameters, after repeating it 3 times, Li Guocheng authorized the adjustment confirmation instruction to Xiaoyi and let it complete the test and adjustment by itself.

This is the power of artificial intelligence robots, hundreds of repetitions, each time so rigorous and accurate.

The next control flight is relatively simple, with the balance control algorithm before takeoff, the attitude control in flight is the younger brother.

There are two modes of flight control: automatic control mode and race mode.

In the automatic control mode, the remote controller gives instructions, and the flight control algorithm needs to optimize the control to ensure the absolute safety of the flight.

In the competition mode, the remote controller gives instructions, and the flight control algorithm is directly executed, which only ensures that the flight is not unbalanced.

The remote control adopts short-wave communication, and the theoretical maximum control distance is up to 12 kilometers, and beyond the control range, it can automatically return according to the memory route.

The reason why it is so complicated is because from the very beginning, it was aimed at the military.
