In the evening, at half past twenty-three.

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

The drones they chose were smaller in size and less resistant to air currents. The test is a dense group flight 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 rushed at the people who were busy.

“OK！” The crowd gestured at him.

"Let's get started."

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

In addition, there is also a column-shaped device 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 location of the device itself, this coordinate information is sent to the host. As well as all the drones in the space enclosed by these four points, which are used for drone positioning and calculating their own position.

The principle is a bit like GPS or our Beidou satellite navigation system, but in a smaller range, the more accurate three-dimensional spatial positioning is achieved.

"The drone and the base point are turned on and connected to the network!" Wu Hao looked at the data on the notebook in front of him and ordered everyone.

"Network connection, networking connection successful, status normal."

"Loaded into the 'Tianyi' system."

"Loading, 5%, 10%, 15%... 100%, Loaded Success! ”

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

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

"Roger." Yang Fan, who was standing on the field, immediately began to check it out quickly when he heard this.

"Three faulty aircraft were launched for testing, and the others restarted normally."

“OK！”

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

Airplanes......

As Wu Hao clicked OK, he saw that the drone propeller marked No. 1 on the field began to rotate rapidly. This was followed by No. 2, No. 3, No. 4......

Until the last one was launched, everyone's hanging hearts finally landed.

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

"Take off next!" Wu Hao said, then circled all the balls in the window with the mouse, 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 1.5 meters above the ground to hover.

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

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

"The following demonstrates the multi-machine marshalling control technology." Wu Hao used the mouse frame to select 20 of the balls, and then detached them from the array.

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

"The next 20 planes move in formation!"

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

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

It was successful, and the hard work of nearly a month was not in vain. From the first string of codes, to the modification of UAVs, to the development of digital coordinate equipment, to today's first cluster flight experiment.

Although the whole process was hard, I was able to see the results. When they saw this Xie drone flying in the air, in addition to excitement and joy, everyone even had a trace of emotion.

This kind of touching is more of an affirmation of the fruits of their hard work in this month, and for young people, there is nothing more proud than the achievements they have made.

"The power is almost up, let's move on to the last project, UAV large cluster array deformation technology."

Under the gaze of everyone, Wu Hao said a word, and then framed all the drones and then imported a pre-compiled model data to them.

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

"Okay, the next step is 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 cubes composed of these drones quickly and slowly deformed.

Syllable...... When the drones were about to form a sphere, all the white balls in the display suddenly turned red, and then fell down one by one.

At the same time, the drone hovering in the air and preparing to form a sphere also lost control in an instant, first swaying from side to side, then colliding with each other, and finally scattered on the ground.

"Holy!"

"What's going on?"

"What's going on?"

……

While exclaiming, everyone quickly gathered here to find out what was going on.

And Wu Hao was even more confused, and he didn't know what was wrong, why it was out of control all of a sudden.

"Haozi, what the hell is going on?" Zhang Jun, who looked anxious, patted him first and asked.

Wu Hao, who reacted, shook his head and said, "It's not clear, it may be that there is something wrong with the system." ”

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

"The first few times were simulated in the computer, as well as a few small-scale marshalling experiments, and today so many drones are being tested together, so there will definitely be some situations." Zou Xiaodong explained to Zhang Jun, who was anxious.

"With just over a week to go before the opening of the show, the organisers asked us to prepare and set up the show at least three days in advance. That said, we have less than a week left. Zhang Jun frowned and said tightly.

As soon as Zhang Jun's words were finished, 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 a little 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 this, then nodded and said, "I know, I'll start here." ”

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

In addition, the shape of the drone is very unstable, and I want you to ensure that the failure rate of the drone must be controlled below 1% when we demonstrate. ”

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

"Okay, action, let's try to test it again in the early hours of the morning." Wu Hao clapped his hands and said.
