Using 3D printing technology and programming, design and produce "nucleic acid detection and sampling robotic arm" to reduce the risk of cross-infection between the detector and the tested person in close contact; use solar energy as a driving energy to make a "solar panel carousel" to achieve energy reuse; integrate Beijing flavor culture and technology to create a "Beijing taste intelligent lunch box" that can both cool and heat and reflect the Beijing style... Recently, the Beijing Women's Federation and the Beijing Youth Science and Technology Innovation Institute cooperated to launch the "Her Science and Technology Creativity" competition, and the girls' whimsy in the field of science and technology and their ability to explore science and technology are amazing.
Epidemic prevention and control Nucleic acid detection and sampling robot
Inventor: Tao Jinbiao, Jin Huilin, Third Central Primary School, Caiyu Town, Daxing District
"Our inspiration came from a nucleic acid test for a throat swab." It turned out that during a nucleic acid test, two primary school students found that although the work of collecting throat swab samples was not difficult, the risk of virus transmission was very high, "We hope to be able to make a machine to help medical staff conduct throat swab detection." So, the two of them started to make it - can the close-up throat swab collection action be handed over to the robot? The two designed a robotic system, including two parts, the patient end and the medical staff end, the doctor only needs to operate the synchronous robotic arm handle in his hand, through the wireless connection, the other end of the patient-side robotic arm can be synchronized operation.
During the production process, the mechanical part of the synchronous robotic arm was designed and modeled by the two themselves, and it was made by 3D printing. The robotic arm is mainly composed of 8 potentiometers to form an angle sensor, and then the angle information is sent to the wireless data transmission module, and the patient receives the data to control the landing movement. The patient end also features UV disinfection and atomization, further enhancing the safety of the throat swab collection process. "Hopefully, when our robots are put into use, they will reduce the risk of infection for medical staff."
Green low carbon solar carousel
Inventors: Nankou School, Changping District, Wang Jingchang, Lu Sixian
Lu Sixian told reporters, "When we played with the carousel in the playground, the trojan horse spun around again and again, giving people a romantic atmosphere. Carousel toys are also often seen in the gift shop, which is pleasing to the eye. However, she found that the finished toys sold on the market are often complex in structure, and most of them use electric energy sources such as batteries as drivers, which are non-renewable and cannot be reused. So the two of them made a clever move, made full use of the waste in life, used their imagination, and made a carousel toy by themselves.
This toy abandons the battery and uses the green energy solar energy as the driving energy to achieve installation and production.
The two students cut a disc shape with cardboard, drilled 6 holes around the disc, hung a wool thread at each small hole, and connected a small vertebral body at the end of the hair line, imitating a rotating Trojan; the beverage bottle was filled with water, the motor was connected with solar panels and fans, and then the disc hanging the "Trojan horse" was fixed to the top of the beverage bottle, and the solar panel was pasted on the bottle.
In the process, the two have also been repeatedly challenged. For example, at the beginning, the cardboard was not firmly fixed, and it would always be crooked on this side and that side, so they thought of a way to stick a disc to the disc to reinforce it. The weight of the "Trojan horse" and the length of the rope, if the angle of sunlight exposure is not well held, will also affect the rotation effect of the "Trojan Horse", so in the test process, the two people constantly adjust, a little closer to the best effect.
When the two men came to the sun with a model of the carousel, the brilliant sunlight shone on the solar panels, and the solar panels generated electricity for the motor, and the motor drove the "carousel" to turn!
Beijing flavor cultural creation Beijing taste smart lunch box
Inventors: Beijing No. 8 Middle School Liu Xinyu, No. 22 Middle School Literature and Art
"What kind of cultural and creative products have both Beijing characteristics and markets?" And this product is best needed by everyone, so that the market is large enough. The two reminisced about the experience they had had in themselves - they had to bring food when they went out to play before, and after a long time, the meal was not fresh. They set their sights on lunch boxes, products that have a large market demand and can integrate scientific and technological elements and Beijing culture.
The two searched on the Internet and found a Beijing special lunch box, but this lunch box has no heating function, just printed the two words of Beijing on the lid, but the price is as high as 500 yuan. Therefore, the two decided to design a lunch box product that not only has a refrigeration and heating function, but also reflects the characteristics of Beijing. "This idea kills two birds with one stone, filling the gap in the two markets of Beijing's special lunch boxes and refrigerated and heated lunch boxes."
They use semiconductor chips to make the lunch box have both heating and cooling functions, and successfully solve the situation that it is easy to break with rice in summer and easy to freeze in winter.
As for the Beijing element, the two came up with a good idea - to launch a Beijing-style gourmet mascot. For example, they designed a cute manga image of fried sauce noodles, and the lunch box was also printed with pictures of many Beijing-style dishes such as grilled meat, fried lamb with green onions, and ma tofu, "Beijing cuisine, Beijing cuisine, you love, I love." The two also drew up such a slogan, which they intend to print on the lunch box, so as to further enhance the Beijing cuisine brand and let people remember Beijing cuisine.
"In the process of research, we found that these are just the tip of the iceberg of Beijing's food culture, and there are more food culture ideas, such as the top ten cuisines, the Beijing Hundred Floors brand, and the food tote bag." For the dissemination of Beijing's gastronomic culture, Liu Xinyu and literature and art have more imagination.
