Military Technology

In the evening, twenty-three thirty.

In order not to affect the training of the school basketball team, they can only choose the time to test after the closing of the basketball hall in the evening.

The drones they chose were smaller in size and less resistant to drafts. The test is to fly in a dense cluster of drones, so the relatively closed environment in the basketball hall is more in line with their requirements.

"Are you ready?" Wu Hao clapped his hands and said to the busy crowd.

"OK!" Everyone gestured at him.

"Then let's begin."

Hearing his voice, everyone immediately took action and placed the charged 240 drones on the court in the middle of the basketball hall.

In addition, a column-shaped device is placed in the four corners of the venue, which is the digital coordinate base point developed and produced by them.

To put it bluntly, this is a spatial coordinate locator. In addition to locating the coordinate position of the device itself, these coordinate information will also be sent to the host. And all the drones in the space enclosed by these four points, which are used for the drone to locate and calculate its own position.

Its principle is a bit like GPS or our Beidou satellite navigation system, but it achieves more accurate stereo spatial positioning in a smaller range.

"Turn on the drone and the base point, and connect to the network!" Wu Hao looked at the data on the notebook in front of him and issued an order to everyone.

"The network connection is made, the network connection is successful, and the status is normal."

"Load the 'Tianyi' system."

"Loading, 5%, 10%, 15%...100%, the loading is successful!"

At the same time, the red lights on the 240 drones placed on the pitch also quickly turned green.

"Check the drones No. 67, 142... 213, 238." Wu Hao looked at the data on the screen and immediately shouted.

"Received." Yang Fan, who was standing on the field, heard the words and began to check quickly.

"Three failures were put out for testing, and the others restarted normally."

"OK!"

Wu Hao took a breath, opened the 'Tianyi' system control window in the notebook, and clicked the startup option.

hum...

As Wu Hao clicked OK, the propeller of the drone marked No. 1 on the field began to rotate rapidly. Followed by No. 2, No. 3, No. 4...

Until the last one started, everyone's hanging heart finally fell to the ground.

At the same time, 237 white balls appeared on the screen of Wu Hao's notebook.

"Next, take off!" Wu Hao said, and then used the mouse to circle all the spheres in the window, and then dragged up in the coordinate system.

At the same time, the 237 drones parked on the ground also quickly rose to a position about one meter five from the ground to hover.

"The reaction speed is quite sensitive." Wu Hao smiled when he saw this.

Zou Xiaodong also nodded and said: "The overall coordination is relatively good. The drone formation starts to rise and hover almost at the same time, and as you can see, the entire altitude position is basically on the same plane."

"Let's demonstrate the multi-machine group control technology." Wu Hao used the mouse to select 20 of the spheres, and then removed them from the array.

At the same time, among the hovering drone swarms, 20 drones flew out of the swarm and then hovered alone in the air.

"The next 20 formations move!"

Up, down, left, right, arc trajectory flight...

Watching the drones complete various planned actions in the air, everyone couldn't help cheering.

It was successful, and the hard work of more than a month has not been in vain. From the first string of codes, to the modification of the UAV, to the development of digital coordinate equipment, to today's first swarm flight experiment.

Although the whole process is difficult, but finally can see the results.

When seeing the Xie drone flying in the air, in addition to excitement and joy, everyone was even touched.

This kind of moving is more about the affirmation of the results of my hard work this month. For young people, there is nothing to be more proud of than the achievements made by themselves.

"The power is almost there, let's carry out the last project, the deformation technology of the large swarm array of UAVs."

Under everyone's attention, Wu Hao said a word, and then he selected all the drones and imported a pre-programmed model data into them.

I saw these drones hovering in the air quickly gathered in the air in the center of the venue according to the model data, forming a suspended cube.

"Okay, next is the array deformation." Just as Wu Hao entered the command, the virtual cube in the window gradually turned into a sphere. At the same time, the cube formed by these drones quickly and slowly deformed.

Slap... Seeing that these drones were about to form a sphere, all the white spheres that were framed on the display suddenly turned red, and then fell one by one.

At the same time, the drone that was hovering in the air and was preparing to form a sphere also lost control in an instant. It first swayed left and right, then collided with each other, and finally scattered on the ground.

"I rely on!"

"what happened?"

"What happened?"

...

While exclaiming, everyone quickly gathered to Wu Hao, wondering what happened.

And Wu Hao was even more stunned. He didn't know what went wrong and why he lost control all of a sudden.

"Haozi, what's going on?" Zhang Jun, who was worried, patted him first and asked.

And Wu Hao, who reacted, shook his head and said, "I don't know yet, there may be a problem with the system."

"Didn't we find any problems when we tested it before, why did it crash today?"

"The previous few times were simulated in the computer, as well as several small-scale marshalling experiments. Today, so many drones are being marshalled together for testing, so there will definitely be some problems." Zou Xiaodong directed at Zhang with a worried face Jun explained.

"There is only a week before the opening of the exhibition. The organizer of the exhibition asked us to prepare and set up the exhibition three days in advance at the latest. In other words, we have less than a week left." Zhang Jun frowned and frowned.

As soon as Zhang Jun finished speaking, Wu Hao waved his hand and said: "These are useless now, our top priority is to find out what went wrong.

Dongzi, you and I checked the system overnight to see what went wrong. "

Although Wu Hao also lied in his heart, as the leader of the team, he must remain calm at this time to calm people's hearts.

Zou Xiaodong glanced at him when he heard the words, then nodded and said, "Got it, I'll start now."

Wu Hao glanced at Zhang Jun, and then shouted at Yang Fan: "Your task is also very arduous, immediately check the drone and check whether there is any problem with the hardware.

In addition, the state of the drone is very unstable. I want you to ensure that the failure rate of the drone must be controlled below 1% during the demonstration. "

Although the task is a bit arduous, but seeing Wu Hao's irrefutable eyes, Yang Fan had no choice but to nod and respond with a sad face.

"Okay, let's do it, let's try to test it again in the early morning." Wu Hao clapped his hands.
