Siheyuan: Starting from a fitter

Chapter 300 Performance of UAVs
Li Guocheng ordered Xiao to exercise his athletic ability while controlling the flight of the drone, and continue to optimize the flight control algorithm.

At this time, he began to think about how to design an eye for the drone.

With the mature robot CCD lens, just by enhancing the appearance design, it becomes an eyeball that can rotate 90 degrees up, down, left, and right, with a scanning angle of 190 degrees.

With the lens installed on the drone, the entire drone weighs only 1200 grams.

Li Guocheng took his Xiaoyi, a drone, and two special laptops (the CPU is the same model as the Kunpeng 2) and drove to a mountainous area in the north of Kyoto.

It wasn't until the car became difficult to move that I locked the door and walked towards the mountainous area.

When he came to a long and narrow canyon surrounded by mountains, he walked around the perimeter and found no human traces before releasing Xiao Yi and the drone.

Instruct Xiao Yi to practice running and jumping on the sand within 100 meters of the surrounding area, and control the speed at 10 kilometers/hour.

Then he opened his laptop, let the drone fly, connected the remote controller directly to his computer, and started to control the drone's flight.

Half an hour later, the following data was obtained:
1. The maximum flight altitude is greater than 5000 meters;
2. The maximum horizontal flight speed is greater than 50 kilometers/hour;

3. The maximum take-off weight is less than 5200 grams;
4. The cruising speed is greater than 20 kilometers/hour;

5. Battery life is more than 45 minutes (load capacity 2000 grams).

Because the fuselage is too light, it is easily carried by the airflow at high altitudes. Fortunately, the flight control algorithm is excellent and it is difficult to lose balance continuously, so it is always under control.

After Li Guocheng replaced the battery of the drone, he took off the drone again and kept it hovering at an altitude of 1000 meters to monitor the surrounding area.

He opened the laptop's monitoring program and connected it to the drone's field of view. If an object intruded, an alarm would be given.

Then he took out another notebook, established microwave communication with Xiaoyi, and received Xiaoyi's status information.

After checking the information and finding that everything was fine, he ordered Xiao Yi to sprint.

The straight-line speed is actually as high as 28 kilometers/hour, and the average speed is 22 kilometers/hour.

Then he was ordered to challenge complex terrains such as gravel, small ditches, boulders blocking roads, and beam ridges at an average speed of 10 kilometers per hour.

I fell down countless times, modified the movement algorithm countless times, and ran again countless times.Half an hour later, the accident happened. While jumping over a ridge, his right forearm was broken when it touched the ground.

When I saw Xiao Yi coming back, there was no intact part of his body. There were scratches, dents and bends everywhere.

After giving Xiao Yi a new body, the test started again.

The battery of the drone was replaced four times during the process, and Xiao Yi damaged a total of three bodies before the result satisfied Li Guocheng.

Back in the laboratory, he began to modify the six-legged robot.

Replacing the mechanical gyroscope directly with a semiconductor gyroscope will save half of the battery pack space.

He re-planned the interior and redesigned the control circuit.The first is to add a semiconductor gyroscope and a drone remote control module in three directions; the second is to change the appearance to make it easier to put in the head.

During the experiment, Li Guocheng found that because the head was equipped with shock-absorbing components, the kinetic energy of the vibration was the smallest, and it was easier to protect the head when it rolled over.

In this way, more space can be freed up in the body for easy modification.

Li Guocheng's first modification was the two tentacles, which can be folded to the back and extended when needed.

There is an automatic ejection port behind the back, which can eject the drone directly into the air.

Return images from the drone and the robot's field of view can also be shared to designated notebooks.

A month later, Li Guocheng brought the latest version of the six-legged robot to the mountainous area last time.

First, the ejection of the drone was tested and it was very successful.The drone was in a startup state before ejection. It ejected to a height of more than 5 meters and quickly regained its balance.

Under the control of the laptop, I made various maneuvers in the air without any problems or lags.

Then give the control to Xiao Yi and let the drone hover on alert.

Since only the position of the control circuit was modified, no problems were encountered in the robot's testing.Xiao Yi, who completed the test, only had a few more scratches on his body.

Returning to the laboratory, he replaced Xiaoyi and Xiaoer with new bodies. They can now be his right-hand assistants.

Li Guocheng will soon be able to copy more assistants if needed.

On this day, Li Guocheng came to the 6th floor carrying a small box.Similarly, Representative Luo once again greeted us early.

He glanced at the suitcase in Li Guocheng's hand and smiled, "Old Li, have you brought me something good again?"

Li Guocheng smiled, "I have a surprise for you."

"Haha, Lao Li, according to you, my expectations have been fully met."

Entering the office, Li Guocheng put his suitcase on his desk and opened it on his own.

Seeing the contents inside, Representative Luo looked confused.

Li Guocheng turned on the switch of the drone, started his laptop, and saw a familiar picture on the screen.

Before Representative Luo could make a serious identification, the drone suddenly flew to a height of 2 meters above the ground, with the camera pointed at Representative Luo.

The sudden takeoff startled Representative Luo, and then he saw the square object with a stand that had been spread out on the table hovering in the air, with an 'eye' staring at him.

Li Guocheng pushed the notebook in front of him, and Representative Luo saw himself staring down on the screen.

Representative Luo kept changing the direction of his head and found that the images inside were also changing, but they were not smooth and kept skipping frames.

The reason is that this notebook is just an ordinary notebook, and Li Guocheng does not want to expose the special notes for the time being.

As the drone slowly rotated, the entire office was visible on the laptop screen.

Representative Luo, who had been staring at the screen, was so shocked by the scene in front of him that his eyes widened and he said, "Oh, this is great."

Then he turned to Li Guocheng and said, "Put it away and go somewhere with me."

After saying that, he picked up the phone on the table, said a few words after connecting it, and then stood aside waiting for Li Guocheng.

Li Guocheng smiled, put the drone and notebook back into his suitcase, and followed Representative Luo in the elevator to the underground parking lot.

An hour later, when I arrived at a playground of the *** Equipment Department, there were already more than a dozen people waiting in the playground.

Although they were also wearing military uniforms, several of them wore glasses and looked like researchers.

After some introduction, it turned out that, as Li Guocheng had guessed, except for a few technical cadres from several ministries, the others were all technical experts.

After getting the signal from Representative Luo, Li Guocheng opened the development, simply set up the laptop, and used the remote control to start the drone.

The drone instantly rose to an altitude of 50 meters and hovered, with the camera focused on the people below.

Representative Luo led everyone to the notebook and gave instructions.

Li Guocheng's remote-controlled drone hovered overhead, suddenly quickly climbed to an altitude of 1000 meters, turned and flew towards the mountainous area. The speed of 50 kilometers per hour gave people a feeling of lightning speed.
