Although they had been harassed by many people over the past few days, they didn't get distracted; instead, they focused all their attention on the testing work.
Nick knew these people were just testing the waters in advance. If they couldn't produce anything after the launch, or if what they produced wasn't ideal, then everything before would be nothing but a pipe dream.
At ten o'clock on the morning of May 20th, accompanied by a fine drizzle, the annual International Innovative Technology Expo finally opened.
The opening ceremony was very lively, attended not only by provincial and city politicians but also by many business representatives. Even Jeff Bezos, the head of Amazon, appeared on the scene. After all, Miami was his home turf, and Amazon's Cloud Computing and Artificial Intelligence were important exhibitors at this fair.
However, this excitement didn't seem to have much to do with Halls C and D. Whether it was the media or the politicians, they were all keen on focusing on those research institutions and tech enterprises.
It seemed that in the eyes of these people, young innovation teams like theirs couldn't produce anything decent.
Of course, to show care and encouragement for these students and young people, the politicians would still take a walk through Halls C and D after visiting Halls A and B.
And this was the opportunity for Nick and his team, and of course, for many others as well. To this end, every team in the venue was actively making preparations, getting ready for the moment the politicians and reporters arrived.
Naturally, they weren't expecting praise from the politicians ; compared to that, everyone actually valued the entrepreneurs around the politicians and the surrounding reporters more.
Looking at the entire exhibition period, this might be one of the few opportunities where media and entrepreneurs gathered in such a concentrated manner.
"Are you ready?" Looking around, Nick asked the somewhat uneasy Zack and Terry behind him.
Terry was the first to respond: "We've been ready for a long time."
"Everything that needs to be prepared is ready. Now we're just waiting for the people to arrive," Zack said, looking toward the entrance with a hint of nervousness.
"They're here, they're here! Everyone, get ready!" Tyler came running in from the entrance, panting, and urged the others.
Seeing this, Nick glanced at the crowd pouring in from the entrance, then turned to nod at Zack and Terry. "Get ready."
"Roger."
"Roger."
The two responded and immediately got busy at their respective posts, while Nick held a tablet, constantly monitoring the movement of the crowd.
Seeing the politicians standing in front of a booth not far from them, listening with a smile to a passionate explanation from a young entrepreneur.
Nick smiled, then swiped open the tablet to launch the software.
Buzz... As the propellers of the first drone in the venue began to spin rapidly, followed by the second, third, fourth... As more and more drones started up, the sound of the spinning propellers grew louder, drawing the gaze of everyone in the hall.
The local leaders and reporters were clearly attracted by the buzzing sound and followed it over. Only the passionate entrepreneur was left standing there blankly, looking at Nick and the others with a resentful expression.
Seeing them approaching, Tyler, who had been waiting in front of the booth, quickly went to greet them. Meanwhile, Nick focused on controlling the drones, trying to present the best side of this system.
In such a small space, controlling a hundred drones to perform swarm formation flight while constantly changing formations was undoubtedly a strict requirement for the entire system and for him as the operator.
Therefore, he had to temporarily block out everything around him and concentrate all his spirit to complete this series of operations.
As Nick operated the tablet, the drones hovering in the middle of the venue began to change formations rapidly, sketching out three-dimensional array shapes.
The hundred drones were seen scattering at times, converging at others, flying in groups, and circling each other.
Next, the hundred drones began to gather toward the center, forming a cube, which quickly turned into an octahedron.
The octahedron slowly began to rotate, then revealed a sphere. The sphere floated up and down, its posture like a balloon suspended in the air, very light.
Clap, clap, clap, clap... The crowd also burst into warm applause for such a brilliant demonstration. But it wasn't over yet; the drones forming the sphere quickly dispersed and then rapidly gathered again.
Just as everyone was still confused, a young female reporter in the crowd exclaimed in amazement, "An apple!"
"That's right, it's an apple. Look, the top and bottom are indented, and there's a stem—isn't that an apple?"
"Really!" Everyone began to discuss it, and even the politicians and entrepreneurs started to smile and praise the display.
A pineapple, a pineapple pen, and so on... wait, that looks like a clock tower, the Eiffel Tower!
...
Just as everyone thought there would be an even more exciting demonstration, the drones dispersed again, forming a cube that filled the entire venue space. Then, the bottom layer of drones began to land, followed by the second layer, and then the third.
As the drones landed, Nick had already put away his tablet and walked up to them.
Clap, clap, clap, clap... The crowd, having come to their senses, also gave warm applause.
"Gentlemen and fair ladies, this is Nick, the developer of this system," Tyler hurriedly introduced him.
"Hello, Nicholas. This performance of yours has really opened my eyes," a mayor in his fifties, wearing a white shirt and slightly balding, said warmly as he shook Nick's hand.
"Thank you, sir. You flatter me," Nick replied, suppressing the excitement in his heart.
The man glanced at the drones that had stopped on the ground and then smiled at Nick. "Mr. Williams [1]just gave us a brief introduction, but our attention was all captured by this wonderful performance. Can you tell us more about the system you developed?"
"Alright." Nick nodded, organized his thoughts, and then introduced to everyone: "The system I just demonstrated is called Swarm-Array Control Technology; it's not the Swarm Control Technology currently on the market.
However, in order to better present this technology to everyone, we chose to use drones as the hardware subject for the demonstration.
In fact, due to time and space constraints, what I just demonstrated is only a small part of this technology; there is still a lot that hasn't been shown.
Under our technology, there are actually four major sub-systems: the Real-time Interactive Remote Control System, the Data Interconnection System, the Interconnected Information Processing System, and the Real-time Attitude Control System."
Seeing the expressions of half-understanding on everyone's faces, Nick had to adjust his approach: "Saying it like that isn't intuitive enough. Let me use the currently popular drone swarm flight control technology as an example.
Traditional drone swarm flight control technology is actually divided into two types: one is swarm flight control technology for moving venues, and the other is swarm flight control technology for fixed venues."
