Almost everyone who has ever held a soldering iron in their hands was interested in radio-controlled models. After spending several months, some of them made a radio-controlled model and faced the problem of power supply for it.

The efficiency and maneuverability of any vehicle is inversely proportional to its mass. It turns out that it is better to bring the batteries out of the model. Then there is no need for radio control, it becomes possible to power the device from a car battery or AC adapter (Fig. 1).

It is good to twist the three wires of the control line into a round cord. This geometric property is found only in a cord of seven conductors (Fig. 2), which can be used for devices with a large number of commands.

The scheme in Fig. 1 has five commands: "Forward", "Back", "Stop", "Right", "Left". As a cord, you can also use a ready-made two-wire from a razor, receiver, radio, etc. In this case, you will have to abandon the "Back" command and slightly change the location of the parts on the control diagram (Fig. 3).

The details of the devices depend on the operating voltage and power of the DC motors used.

Machine for thinning flowers in gardens 02.05.2024

In modern agriculture, technological progress is developing aimed at increasing the efficiency of plant care processes. The innovative Florix flower thinning machine was presented in Italy, designed to optimize the harvesting stage. This tool is equipped with mobile arms, allowing it to be easily adapted to the needs of the garden. The operator can adjust the speed of the thin wires by controlling them from the tractor cab using a joystick. This approach significantly increases the efficiency of the flower thinning process, providing the possibility of individual adjustment to the specific conditions of the garden, as well as the variety and type of fruit grown in it. After testing the Florix machine for two years on various types of fruit, the results were very encouraging. Farmers such as Filiberto Montanari, who has used a Florix machine for several years, have reported a significant reduction in the time and labor required to thin flowers. ... >>

Advanced Infrared Microscope 02.05.2024

Microscopes play an important role in scientific research, allowing scientists to delve into structures and processes invisible to the eye. However, various microscopy methods have their limitations, and among them was the limitation of resolution when using the infrared range. But the latest achievements of Japanese researchers from the University of Tokyo open up new prospects for studying the microworld. Scientists from the University of Tokyo have unveiled a new microscope that will revolutionize the capabilities of infrared microscopy. This advanced instrument allows you to see the internal structures of living bacteria with amazing clarity on the nanometer scale. Typically, mid-infrared microscopes are limited by low resolution, but the latest development from Japanese researchers overcomes these limitations. According to scientists, the developed microscope allows creating images with a resolution of up to 120 nanometers, which is 30 times higher than the resolution of traditional microscopes. ... >>

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

Heart for biorobots 25.07.2022

American scientists have invented a rubber deformable pump that mimics animal biology and can serve as a "heart" for robots made of soft materials.

Researchers at Cornell and the US Army Laboratories have developed a "circulatory system" center similar to the heart of biological creatures, designed to increase the mobility and independence of robots. The resulting "heart" is an elastomeric pump that works due to hydrodynamic and magnetic forces.

Previously, similar pumps were already built into biorobots, but they were located outside, looked very bulky and allowed energy to be wasted. The engineers managed to hide the new design inside, since it consists only of a soft silicone tube and coils of wire - solenoids, which are located around the device at a short distance from each other and allow the pipe to stretch and bend.

In the tube, as conceived by the developers, a solid core of a magnet is also hidden, which acts on the principle of a piston and pumps "blood" with constant force. As a necessary fluid, scientists used oils with low viscosity. Compared to solid solution pumps, the performance shown is about ten times lower.

The authors tracked performance parameters in order to adapt their design to different types of robots. As a result of experiments, the researchers found that such a pumping system can operate continuously and effectively mimic the heart.
