Super Copy of Great Power Technology

After the three new mobile phones were released, Zhao Hongcai introduced a new product developed by Ruida Technology, which was a four-axis drone that performed a light show at the Ruida Group's annual meeting. The holographic projection behind it was also replaced with a light show clip.

"Quadcopter drones are electronic products that have become popular in recent years. There are many brands of quadcopter drones on the market now, with different performance and functions, and prices ranging from one or two hundred to tens of thousands. At least 80% of these drones have obvious defects, such as short battery life, rubbish cameras, blurry photos, poor wind resistance, no positioning system, or all of the above defects, and can only be used as toys. It is quite difficult for consumers to buy a quadcopter drone with complete functions, mature flight control, and can be used as an aerial photography tool. The price must be at least four or five thousand to meet the requirements.

Everyone must have watched the annual meeting of Ruida Group last year. Do you still remember the quadcopter drone that appeared in the opening performance? That was the Ruida MINI quadcopter drone developed by our Ruida Technology R&D team in half a year.

Having said that, Zhao Hongcai waved towards the staff next to him. The next moment, there was a buzzing sound, and a small drone painted in contrasting black and white took off from behind the crowd, flew over the crowd, flew into the camera range, and hovered not far in front of Zhao Hongcai. Zhao Hongcai also stretched out his right hand at the right time and opened it upwards. The camera of the drone rotated downward and locked the position of the palm. The flight control continuously adjusted the position of the drone until it was directly above the palm, and then slowly descended, finally landing on Zhao Hongcai's palm. The sensor detected that the drone had successfully landed on the palm, and the four propellers immediately stopped to prevent injury.

Seeing this small quadcopter drone, the attention of the audience and netizens in the live broadcast room were all attracted to it.

"It's great that the quadcopter drone of Ruida Technology has finally been released. Last year, I watched the live broadcast of Ruida Group's annual meeting, and the drone light show at the beginning shocked me for the whole year. At that time, I was thinking about such an advanced drone. I must buy one after it is launched. I didn't expect that I would have to wait for more than half a month."

"What a small and beautiful drone. It's much smaller than the drones on the market."

"You caught the drone with your hands. Aren't you afraid that the propellers will hurt your arms?"

"Have you noticed that this drone flies very steadily? It is very stable when traveling, flying, hovering and landing."

"Landing a quadcopter drone has always been a big problem. If the flight control is not well programmed, it will be difficult for the drone to land smoothly on the ground. Not to mention landing directly on the palm of your hand, the difficulty is at least dozens of times higher."

"I also caught the drone with my hands, but the propeller cut my arm several times, and I had to get several stitches at the hospital. I would like to advise everyone not to do this unless you are absolutely sure."

"Didn't you see that the propeller stopped spinning as soon as the drone landed on Mr. Zhao's palm? How could it be dangerous? Obviously, the flight control and sensors of this drone are good enough to automatically determine the current flight status. Once it lands on the ground or on the palm, the propeller will stop spinning immediately. This flight control technology is quite advanced. I hope other companies will follow suit as soon as possible."

"The drone flies smoothly and can land directly on the palm of your hand. This is all due to its complete sensors and excellent flight control. It is very difficult for small factories that produce toy drones to imitate Reda Technology's drone products."

Zhao Hongcai, who was at the press conference, of course could not see these messages in the live broadcast room. His attention was all focused on the drone in front of him. He put his five fingers together, grasped the fuselage of the drone, turned it vertically, showed it to the audience around him, and said: "I am talking about this little guy. The reason why I call this drone a little guy is that it is quite small and light, only 430 grams, less than one pound. As you can see, this four-axis drone adopts a folding design. Not only can the four arms be folded to the sides of the fuselage, but the four propellers can also be folded up and placed on both sides of the fuselage. In the unfolded state, the size of the drone is 168*184*64mm, and in the folded state, the size is only 168*83*49mm, which is the size of a power bank. You only need to use the magic buckle provided randomly to put it in your pocket or backpack.

That friend may ask, what can such a small drone do? It can't be just a toy, right? If you think so, you are wrong. Other companies make drones smaller to reduce weight, reduce batteries, and save costs. We at Ruida Technology make drones so small purely for portability, which is also a reflection of our technical strength. There is absolutely no reduction in function and battery life.

First, let me introduce the gimbal and camera of this drone. Our R&D personnel have integrated a 4K three-axis gimbal camera into the compact body. The gimbal control accuracy reaches an astonishing 0.005 degrees, which significantly improves the stability of the picture during flight. The camera uses a 1/2.3-inch 2400-megapixel CMOS sensor, coupled with an integrated design lens with an equivalent 24mm focal length and f/2.8 aperture that is particularly suitable for landscape photography. It can easily take high-resolution photos and videos, and can shoot up to 4K60 frames of images. For daily use, it is enough to record the scenery of the journey. In addition, we have integrated two 1200-megapixel cameras on the left and right in the front of the fuselage, which can be used for front obstacle avoidance and for shooting 3D holographic images. Although the resolution of these two cameras is not too high, they are enough for travel souvenirs and short video creation.

Let's talk about the fuselage design. The arm of our Ruida MINI quadcopter drone adopts an original three-dimensional folding design, which feels just right. Even after thousands of foldings, it can still ensure stability during flight. The area of ​​the folded aircraft is equivalent to that of a mobile phone, allowing you to easily control it with one hand. After folding, the overall fuselage looks quite light and compact, and the embedded design provides all-round protection for the gimbal camera. The folding landing gear has a built-in antenna to enhance the signal reception and transmission during flight. Making full use of every inch is the reason why our Ruida mini drone can still guarantee long-term output of strong performance while compressing the fuselage volume.

In terms of sensors and flight control systems, our R&D team has created the FlightAutonomy system. It uses advanced visual inertial odometer technology and integrates 15 sets of sensors such as front, bottom and rear binocular vision, so that our MINI drone can have insight into the surrounding environment, know the posture of the fuselage, and have more accurate hovering and stable flight performance. Through APAS (Advanced Flight Assistance System) technology, the aircraft can even actively bypass obstacles in front and behind, and the flight experience is fully upgraded. All-round protection makes the journey of discovery more relaxed. Another major advantage of our Ruida MINI drone is its long-lasting battery life. Our engineers installed a graphene battery with a voltage of 11.55V and a capacity of 9300mAh in a very limited fuselage. It is precisely because of this battery module with a very high energy density that the flight time of the Ruida MINI drone easily breaks the 60-minute mark, allowing you to fly enough at one time. This battery module adopts a fast charging and detachable design. Charging with the matching charger can reach a maximum charging power of 60W, and it only takes half an hour to fully charge the battery. A quick-release buckle design is used between the battery module and the host. If you still feel that the battery life of one battery is not enough, you can buy multiple batteries and replace them, completely saying goodbye to battery life anxiety.

Let's talk about the ESC and power system of our drone. Its ESC adopts FOC sine wave drive architecture, which makes the motor commutation smoother and improves the total power of the motor ESC. The power system has been tested for tens of thousands of hours to ensure flight safety. And after our field tests, even at an altitude of 5000 meters, the Ruida MINI drone can still take off and work normally. After turning on the sports mode, the Ruida MINI drone can reach a maximum speed of 90 kilometers per hour, and it is not a problem to track moving cars or ships and follow them.

Finally, let's talk about the control system and image transmission system of the Ruida MINI drone. Our drone uses 2.4GHZ frequency band wireless control and 2.4/5.8GHZ dual-band WI-FI image transmission system, with a 4P real-time image transmission and control distance of more than 720 kilometers. You can download the Ruida drone APP on your mobile phone, and after pairing it with the Ruida MINI drone, you can use your mobile phone to remotely control the drone at a close distance and view the image information sent back. Of course, the wireless transmission power of the mobile phone is limited, and the antenna is not too large, so the control distance is very limited. In the absence of obstructions, it is about 4 meters. If you feel that the mobile phone remote control distance is too close and you are not happy with the flight, you can also buy a matching remote control to achieve a maximum flight control of KM for the drone and receive the returned images.

So, how much does such a powerful and long-lasting quadcopter drone cost? Please see the virtual projection. There are three packages here. The basic package only includes a Ruida MINI drone, eight foldable propellers, a battery, a propeller tie and four propeller protectors. The price is 1599 yuan. The upgraded package, in addition to all the products of the basic package, also has a remote control that can achieve long-distance control of the drone. The price is 1999 yuan. The Shuangfei package includes all the products of the basic package, the remote control, and two spare batteries. The price is 2499 yuan.

As soon as the price was announced, it once again caused an uproar in the audience, followed by warm applause that lasted for a long time. The reason why people were so excited was that the price of the Ruida MINI drone was too cheap. Before today, other first-line drone brands in China also launched a number of fully functional and easy-to-use quadcopter drone products, but the prices were generally over 3000 yuan, which is about the same as the price of a flagship mobile phone. Now Ruida Technology has launched its first drone product, which is fully functional, has excellent software and hardware, and has a longer battery life, but the price is only about half of the former. How can everyone not be excited?

"I think Ruida Technology is really good. The new drone has such excellent performance, but the price is only 1600 yuan. It is really good value for money. I am tempted by it."

"From the hardware parameters, the performance of the Ruida MINI quadcopter drone is indeed powerful, but the specific flight control level, whether it is as good as Mr. Zhao boasted, we have to get the actual machine and test it to know."

"Have you noticed that the Reda MINI drone can actually shoot holographic images? When paired with the previously released Xingyao mobile phone, it can be used to shoot 3D holographic movies without any problem, right?"

"4K resolution is still a bit low and is not enough for professional film and television shooting. It would be great if Reda Technology could launch a PRO version of the drone and increase the camera resolution to 8K60 frames."

"I'm a drone enthusiast and part-time wedding photographer. I have DJI Phantom 1, 2, and Inspiration, as well as dozens of other brands of drones. This is the first time I've seen a drone as small and portable as the Reda MINI. The description says it has a long battery life, but I don't know how it can withstand winds. With such a small body, it won't fly away if it's blown away, right?"

"I am a travel blogger and I need a drone to take aerial photos. I had my eyes on the Phantom 2 before, but it was too big and too expensive, so I held off on buying it. Now I see the Ruida MINI, which is compact, has a long battery life, and is very cheap. It fully meets my needs. Hurry up and buy one. I will buy one right away."

"Drones are only useful when traveling and sightseeing during holidays. They are rarely used during work hours. I hope everyone will not make impulse purchases."

"It's only 1600 yuan, so I can just buy a few less pieces of clothing. It's such a cheap product, I won't feel bad even if it gets covered in dust."

After announcing the price of the drone, Zhao Hongcai put away the drone, left the podium, came to the staff, took the mineral water, unscrewed the bottle cap, tilted his head back and drank a few sips. The products to be released later were all small things such as smart sockets, gallium nitride chargers, and smart speakers. Zhao Hongcai didn't need to introduce them personally, and he could just send a product manager to explain them.

Half an hour later, the Spring Conference of Ruida Technology officially ended. Amid the warm applause of the audience, Zhao Hongcai and most of the staff packed up their things, left the lawn, and returned to Ruida Building. Only a small number of security personnel and cleaning staff were left to evacuate the crowd, clean up, and use sprinkler irrigation to restore the lawn to its original appearance.

It was six o'clock in the afternoon, and it was time for the Ruida Group to get off work. However, the number of employees who left the Ruida Building on time today and rushed home was less than half of the usual number. In the Ruida Network Building next door, there were even fewer people leaving the building after get off work, only a dozen or so. What were the rest of the people doing? Of course, they were paying attention to the backend data of the Ruida Mall to see how the sales of the new products that Ruida Technology had put on the shelves were. (End of this chapter)
