Moscow schoolchildren strive to choose their future profession as early as possible. They are still children, but they are able to solve problems that not every adult can handle. For example, how to set up a vegetable garden right in the apartment or protect yourself from pickpockets.

More than 45 thousand Moscow schoolchildren are learning in pre-professional classes, including engineering. Thanks to these projects, high school students can decide on their future profession during their studies. Some have already received the status of young inventors and won more than one competition. To communicate with such guys, the correspondent had to make an appointment in advance: there are practically no free pages in their organizers. Read about the creators of the portable greenhouse, bear thermometer, cleaner ship and alarm for mobile phones and wallets in this article.

Kitchen garden in the apartment

Three years ago, seventh graders from the Bauman Engineering School No. 1580 decided to create a smart home project at their leisure, in which everything is automated, compact, environmentally friendly, convenient, where there is even a portable vegetable garden. At first, the guys were going to reproduce such a house from a cement mixture on a 3D printer.

“Soon we realized that we, schoolchildren, could not afford the idea. But you can make a smart greenhouse yourself, ”recalls tenth grader Rodion Stramous, one of the inventors of the Green Box greenhouse.

Only two out of seven young scientists made it to the launch of the project – Rodion Stramous and Yegor Skorokhod. According to Yegor, work on the Green Box has become a hobby for them. The greenhouse was assembled in a couple of weeks. The result is a metal box with a window, similar to a computer processor. Inside it, there are three shelves located one above the other. Seedlings are placed on them – in pots or directly in the ground. Next, the mini-computer mounted in the Green Box is given a program depending on which plant is in the greenhouse. Heaters, fans and water sprayers create a microclimate that is monitored by sensors.

“These are air and soil moisture sensors, as well as an electronic sensor that determines the degree of lighting and heating. The information is displayed on a display connected to the Green Box. You can adjust the temperature and humidity using the buttons on the player-type device. But we want to develop an application for smartphones to make control more convenient, ”says Yegor Skorokhod.

Two years ago, the guys took Green Box to Jakarta to the international exhibition of young inventors Youth for Better Future and took third place. The teacher of Yegor and Rodion Svetlana Buldygina, the ideological inspirer, recalls: it was she who invited the boys to apply for participation in the exhibition.

“The issue of our participation was resolved in a week. The team was included in the Russian team of young scientists. They pulled up English on the way, on the plane. The guys prepared a presentation of the greenhouse and conveyed the main idea to the visitors in such a way that people were delighted. Even the Japanese, whose technology is at the highest level, appreciated it. I was amazed how the boys got the idea to present the Green Box abroad, how they coped with difficulties on the spot. For example, during one presentation, a glitch occurred: the lighting inside the greenhouse did not work. The guys fixed this problem themselves. Our team was recognized as the most friendly, ”says the teacher.

According to Svetlana Buldygina, a greenhouse is a product that can be brought to the market. The greenhouse body is designed to fit into kitchen furniture like a dishwasher. Also, for a greenhouse, you can come up with a design that will fit into the interior, then the Green Box will also perform an aesthetic function. In the meantime, Yegor’s mother is testing the greenhouse – she grows greens at home.

Panda Nurse

The idea to create a baby thermometer was born at school No. 1354 “Vector” during a pandemic.

“Before the pandemic, we worked on a thermal imager – a device that protects the computer from overheating. They did not have time to finish the project. We need more thermometers for measuring body temperature. We were approached by a senior teacher of a neighboring kindergarten with a request to invent a thermometer that would not frighten the kids. After all, children, as a rule, are afraid of everything related to medical procedures, ”says Andrei Zhuravlev, a robotics teacher at school No. 1354 and curator of the project.

Andrey and his 11th grade students decided to sew a thermometer into a toy. At first, they thought to print it on a 3D printer. But then we realized that it is more pleasant for the baby to see a soft bear, and decided to use a plush panda. Work on the project took about a month. The most difficult thing, from the point of view of the inventors, was to make the device work at a distance, when the child simply picks up the toy. This required a sensitive sensor, and this was nowhere else. As a result, the guys found the required element at one of the Moscow factories.

“The sensor is located in the nose of the panda. When the child takes the toy and hands and looks at it, the temperature is measured. The data is sent to a mini-display on the back of the bear, ”explains one of the project’s founders Ivan Smolyak.

While the panda thermometer exists in a single copy. The inventors believe that this is a seasonal product, but Andrey Zhuravlev does not rule out that if the device is modified, it can become competitive in the market.

Mobile anti-theft

Fyodor Boyko, a student of the 11th grade of engineering at school No. 947, has developed a portable alarm system for mobile phones and wallets.

“The scientific supervisor suggested that we think about a social project, and my direction was radio electronics. And I wondered: how to combine it? I started looking for an answer on the Internet and ended up on the Rosstat website. I found out that, unfortunately, the level of pickpocketing in the country remains high. I was imbued with this problem. I understood: you need to protect yourself and your loved ones. In a month I created the first model, ”says Fedor.

The alarm consists of a sticker that is attached to a phone, wallet or passport, and a box with an infrared receiver, remotely connected to the sticker (the TV remote control works in a similar way). As soon as the pickpocket pulls out the phone, the box beeps and vibrates. Now Fedor is working on a new alarm model that will stop the thief before he gets his phone or wallet.

A senior pupil with his portable alarm system became the winner of the regional round of the All-Russian competition of scientific and technological projects “Big Challenges”. According to physics teacher Irina Batayeva, who oversaw the project, the anti-theft agent will certainly be in demand.

“There is an idea to create design variants of the case, for example, in different colors and shapes. I am very glad that Fedor comes up with everything himself, I only help with the description of the project, and the curator from MIREA Mikhail Krizhanovsky – with the technical details, ”clarifies Irina.

Ocean Cleaner

According to the chief engineer of the autonomous system for monitoring and cleaning water bodies from surface pollution, an eleventh grader of school No. 2031 from Kosino-Ukhtomskiy Alexander Radchenko, the idea to create a project came after the environmental disaster in Norilsk in May 2020. Then there was a serious oil leak due to the depressurization of the tank.

“The news of this disaster impressed me. We decided to develop a device that will help in the shortest possible time to eliminate the consequences of an oil spill and clean the surface of the reservoir from pollution. On a 3D printer, a 30 x 30 cm parallelepiped body was printed, on which an engine and a bucket were installed. Inside the ship, sensors were placed that control the sorting of garbage, and a transparent bucket was attached to the outside, collecting dirt from the surface of the water and throwing it on board. The ship is controlled from a smartphone ”, – Alexander comments.

The entire design team of the school under the guidance of the teacher of mathematics Tatyana Lebedeva worked on the ship. Each of the young engineers was responsible for his own area. For example, a friend of Alexander’s Maxim Bolotov was engaged in a garbage sorting device. After six months, the model was ready.

“True, during the first test in the bathroom, we realized that the boat was imperfect: the bucket was throwing colored balls on board, imitating all sorts of garbage, like from a catapult. I had to replace it with another bucket that collects the garbage carefully, ”recalls Alexander.

At the competition of the Moscow Polytechnic University “Engineering start” one more drawback was revealed: when the ladle grabbed balls from the surface of the pool, the ship’s center of gravity shifted and the hull tilted. In addition, the battery was running out quickly. Nevertheless, the guys took second place, in addition, the jury members recognized the project as the best product of the tournament. Now the team is finalizing the model.

“We need to add capacity to the battery and change the center of gravity,” explains Alexander.

Schoolchildren, according to Tatyana Lebedeva, plan to participate with this development in the competition of projects and research “Engineers of the Future” in the framework of the conference of the same name and the Moscow city competition of research and design works. The inventors are sure that if the boat is enlarged, it can be used in practice – to cleanse the seas and oceans.
