In the evening, half past twenty-three.
In order not to affect the training of the school basketball team, they could only choose the time to conduct the test in the evening after the basketball hall was closed.
The drones they chose were smaller in size and had poor airflow resistance. The test involves drones flying in dense clusters, so the relatively closed environment in the basketball stadium is more in line with their requirements.
"Are you ready?" Wu Hao clapped his hands and said to the busy people.
"OK!" Everyone gestured to him.
"Then let's get started."
Hearing his voice, everyone immediately took action and placed the 240 charged drones neatly on the court in the middle of the basketball stadium.
In addition, there is a columnar device placed at the four corners of the venue, which is the base point of the digital coordinates they developed and produced.
To put it bluntly, this is a spatial coordinate locator. In addition to positioning the coordinate position of the device itself, these coordinate information will also be sent to the host. And all drones in the space surrounded by these four points are used for drone positioning and calculation of their own positions.
The principle is a bit like GPS or our Beidou satellite navigation system, but it achieves more accurate three-dimensional 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.
"Connect to the network, the network connection is successful, and the status is normal."
"Load the 'Tianyi' system."
"Loading, 5%, 10%, 15%...100%, loading successfully!"
At the same time, the red lights on the two hundred and forty drones placed on the court quickly turned green.
"Check drones No. 67, 142...213, 238." Wu Hao looked at the data on the screen and then shouted.
"Copy that." Yang Fan, who was standing on the field, immediately began to check quickly after hearing this.
"Three aircraft failed and were put out for testing, and the others restarted normally."
"OK!"
Wu Hao took a breath, opened the 'Tianyi' system control window in his laptop, and clicked on the startup option.
Buzz…
As Wu Hao clicked OK, the propeller of the drone marked No. 1 on the field began to rotate rapidly. Then came No. 2, No. 3, No. 4...
It wasn't until the last one started that everyone's anxious hearts finally settled.
At the same time, 237 white balls appeared on the screen of Wu Hao's laptop.
"Take off next!" Wu Hao said, then used the mouse to circle all the balls in the window, and then dragged them upward in the coordinate system.
At the same time, the 237 drones parked on the ground quickly rose to a position about one and a half meters above the ground and hovered.
"The reaction speed is quite sensitive." Wu Hao smiled upon seeing this.
Zou Xiaodong also nodded and said: "The overall coordination is relatively good. The drone formation started to rise and hover almost at the same time, and you can see that the entire height position is basically on the same plane."
"The following demonstrates the multi-machine grouping control technology." Wu Hao used the mouse to select 20 of the balls, and then removed them from the array.
At the same time, among the cluster of drones hovering in the air, 20 drones flew out of the cluster and then hovered alone in the sky.
"The next 20 aircraft will move in formation!"
Up, down, left, right, flying in an arc...
Everyone couldn't help but cheer as they watched the drone complete various planned actions in the air.
It worked, and the hard work of the past month or so was not in vain. From the first string of codes, to the modification of the drone, to the development of digital coordinate equipment, to today's first cluster flight experiment.
Although the whole process is hard, I can finally see the results. When they saw this drone flying in the sky, everyone was not only excited and happy, but also a little moved.
This kind of touch is more of an affirmation of the fruits of one's hard work over the past month. For young people, nothing can make them more proud than the achievements they have made by themselves.
"The battery is almost gone. Let's work on the last project, UAV large cluster array deformation technology."
Under the gaze of everyone, Wu Hao said something, then selected all the drones and imported a pre-programmed model data to them.
The 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 composed of these drones quickly and slowly deformed.
Bang... Just when these drones were about to form a sphere, all the white spheres selected in the display suddenly turned red, and then fell down one by one.
At the same time, the drones hovering in the air and preparing to form a sphere also lost control in an instant. They first swayed left and right, then collided with each other, and finally scattered on the ground.
"Holy shit!"
"what happened?"
"What happened?"
…
While exclaiming, everyone quickly gathered around Wu Hao, wanting to know what happened.
Wu Hao was even more confused, not knowing what went wrong and why he suddenly lost control.
"Haozi, what's 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 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 all computer simulations and several small-scale grouping experiments. Today, so many drones are conducting grouping tests together, so some situations will definitely occur." Zou Xiaodong said to the anxious Zhang Jun explained.
"There is only more than a week until the opening of the exhibition. The organizer of the exhibition requires 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.
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 will check the system overnight to see where the problem is. "
Although Wu Hao was also lying in his heart, as the leader of the team, he had to stay 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 now."
Wu Hao glanced at Zhang Jun, and then shouted to Yang Fan: "Your task is also very difficult. Check the drone immediately and check if 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 our demonstration. "
Although the task was a bit difficult, seeing Wu Hao's eyes that could not be refuted, Yang Fan had no choice but to nod his head and agreed with a sad face.
"Okay, let's take action. Let's try to test it again in the early morning." Wu Hao clapped his hands and said.
