Chapter 144: First obstacle test

Although there were many differences in the research and development of the 'battle sweeper' high-speed attack drone, Yang Fan and Pang Yifei jointly launched the first engineering prototype of high-speed attack drone.
There are many reasons for this. In addition to the time constraints, it is too difficult to accurately identify and avoid obstacles in high-speed flight.
In Pang Yifei's words, this is more than ten times more difficult than the current driverless technology.
Of course, this is an exaggeration. But this technology is really difficult. The difficulty is that it is fast.
First of all, the limited volume and load limit the equipment that can be carried on this drone. The more equipment, the larger the drone, which means that it is more inconvenient to carry and the higher the probability of being detected and intercepted by the enemy.
Similarly, more equipment means more weight for drones. With limited power, drones will be slower. This also means that this drone will lose the suddenness of attack on the enemy, increasing the probability of enemy discovery and interception.
But if the volume and load are controlled, the equipment on it is very limited. This also means that the number of various types of sensors cannot be too large, the size cannot be too large, and the power cannot be greater.
The low power also limits its detection distance, reduces the response time, and increases the difficulty for the UAV to avoid obstacles.
Therefore, after the two teams fiddled with each other for more than a dozen days, Yang Fan's initiative to speak finally got Pang Yifei's response immediately.
Then the two teams merged together to learn from each other's strengths, which led to phased progress in technical research in this area.
"This is the high-speed attack drone you developed?" Wu Hao frowned as he looked at the black drone, the size of two adult palms.
As the limited time is getting closer, Wu Hao has been closely monitoring the research progress of this project. I heard that the project has made phased progress. After the first complex terrain test is about to be performed, Wu Hao rushed over.
But this drone is a little disappointed. The diameter is more than forty centimeters, which is almost the same as the civilian 'elves' on the market.
Because it is a test engineering machine, it is relatively rough. There is no shell on the fuselage, which is full of various components and messy wiring.
After seeing the disappointment on Wu Hao's face, Yang Fan said with a smile: "This is only our engineering prototype. If the test is successful, it will be further optimized. At that time, the volume will continue to shrink, and it cannot be as large as it is now. . "
Wu Hao nodded his head, looked at the engineering prototype in front of him, and asked, "How to test?"
Pang Yifei smiled and explained to him: "We have an obstacle passage with a total length of more than 100 meters around the experimental building in our company park.
We let the drone fly over this obstacle line to see if it can successfully cross it, and how long it will take. "
Wu Haowen nodded his head. When he came, he did see the relevant facilities outside the experimental building. He didn't know what it was at first, but now he finally understands its real purpose.
"Is the whole process completely autonomous in judging flight?" Wu Hao asked for a moment.
Yang Fan nodded and said, "We just plan the relevant flight routes, and the specific path is up to it."
Hearing Yang Fan's words, he finally smiled, and then waved his hand: "Let's get started."
Pang Yifei nodded and said, "Okay, we are finally going to debug it, and it will be fine soon."
Talking, he and Yang Fan and other technicians started to work independently. Although this is only a simple test, it can be seen that everyone is under great pressure, and it is inevitably a little nervous when approaching the test.
After about 20 or 30 minutes of debugging, after seeing that the data is normal, Yang Fan and Pang Yifei and they took the drone down the stairs and came to the proposed test channel.
The entire passage surrounds the outer wall of the experimental building in a '冂' shape. In addition to two sharp 90-degree bends, the obstacles are also arranged inside the passage, including horizontal wooden boards, treetops, and other obstacles.
Therefore, the space for drones to pass is actually very small, let alone drones, even if people are passing through the passage, it takes a lot of effort.
In order to record the status of this test, in addition to the camera camera on the drone, the project research and development team also deployed some GoPro cameras in the channel. In addition, there are also several technicians holding cameras to stand in various corners to shoot, ensuring that the complete test process can be recorded from various angles, so that the scientific research team can use these video data for analysis and research.
Wu Hao found a better viewing position around the corner, and then shouted at Yang Fan who was still preparing for the job.
"Are you ready?"
After hearing his shout, although Yang Fan was still hesitant, he finally nodded: "Okay!"
"Then start." Wu Hao waved.
Yang Fan took a deep breath, then nodded at the Ping Yifei standing next to him to start. Pang Yifei glanced at the drone placed on the takeoff frame, and then pressed the start switch.
Hum!
The drone instantly jumped from the takeoff frame and then quickly flew towards the obstacle course. The speed of the drone dropped significantly when it came in contact with the obstacle course, but it was still very fast.
I saw that the drone began to dodge left and right in the obstacle channel, swept higher and lower, and was very flexible.
Hum ...
The drone turned around from the corner in front of Wu Hao, which made Wu Hao and everyone applaud.
Yang Fan, who had been staring at the surveillance screen, heard a smile, his face also smiling. However, he was still staring at the screen, afraid to have any slack.
The test had failed too many times before, and they didn't want to have another painful experience this time. For scientific and technical personnel, no one is more frustrated than the failure of the project test that he is responsible for.
Many scientific researchers even described: "At the moment of failure, it was as if an invisible hand had taken away all my strength from me. I collapsed to the ground and my colleagues next to me tried to support me, but I can't stand up, my mind is blank. "
Da, Da, Da!
Three consecutive sounds brought his heart to his throat.
This is the sound of the drone bumping into an obstacle ~ EbookFREE.me ~ Although the drone is still flying, the speed is obviously reduced a lot.
"What's going on?" Yang Fan asked.
Pang Yifei stared at the screen, his face slumped: "It's not clear yet, we can't find out the reason until the test is over to study the flight trajectory and monitoring picture."
"Fly out!"
Excited technical staff nearby!
Papapap ... Everyone watching the test also burst into warm applause.
Only Yang Fan and Pang Yifei stood in the crowd with pained faces, watching the obvious bump marks on the drone flying down.
