Three models of planetary rovers. Tips for a modeler

Modeling

"Galaxy"

Planet rover "Galaktika" is a four-wheeled off-road vehicle controlled by a radio transceiver. Its creators, brothers Sergei and Yuri Khaloimov from the city of Livny, Oryol region, made the wheels not solid, but consisting of separate spokes-legs, bent at the end and "shod" in rubber shoes. Hence the design feature: the wheels do not roll, but, as it were, step over obstacles.

According to the idea of the guys, the planetary rover can also be used in terrestrial conditions. It can move on loose sands, forest clearings, mountainous and rocky terrain.

The mechanical drive of the "Galaktika" consists of a micromotor with a gearbox made from an old alarm clock; it drives a pair of wheels. Through the second gearbox, to which the movement is transmitted through the belt from the shaft of the first gearbox, the locator antenna rotates.

To control the model, a receiver with an actuator is installed on its platform, which turns on commands in turn. The battery for the receiver and the traction motor is also located here.

The model executes the following commands: move forward (at this time, the lights come on, simulating the operation of the locator); front and rear spotlights turn on; move forward (in this case, the front spotlights light up); stop - turn on the front and rear spotlights.

At the end of the model, the power switch is switched to the "off" position.

"Venus"

“It was the painting “Extraterrestrial Life” by science fiction artist A. Sokolov that prompted young technicians of the space modeling laboratory of the Kaluga region to create a planetary rover of this kind,” the head of the laboratory, Ya. I. Shmarev, tells us.

They presented it as a large inverted plate with a spherical superstructure. The double walls of the dome are made of durable material, coolant circulates between them. The crew, being under such a shelter, according to the guys, can freely conduct scientific work.

At the bottom of the base should be placed undercarriage and rocket launcher. The undercarriage gives the rover the ability to move on the ground on wheels, and when the rocket launcher is turned on, it can rise up and soar. True, the guys have not yet been able to install a jet installation.

The rover model consists of two main parts: chassis and body. Remote control is carried out from the remote control. "Venus" can move forward, backward and make turns. Powered by two micromotors with friction transmission to each of the drive wheels. Battery powered.

"Saturn"

The spherical design of the mover, according to the guys from the city of Chapaevsk, Kuibyshev region, most rationally ensures the movement of the planetary rover with the least energy consumption. The openwork wheels of the planetary rover made of plastic reinforcement provide increased cross-country ability. The central control post is located above the living quarters and the motor part.

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>

Primium Seneca keyboard 05.05.2024

Keyboards are an integral part of our daily computer work. However, one of the main problems that users face is noise, especially in the case of premium models. But with the new Seneca keyboard from Norbauer & Co, that may change. Seneca is not just a keyboard, it is the result of five years of development work to create the ideal device. Every aspect of this keyboard, from acoustic properties to mechanical characteristics, has been carefully considered and balanced. One of the key features of Seneca is its silent stabilizers, which solve the noise problem common to many keyboards. In addition, the keyboard supports various key widths, making it convenient for any user. Although Seneca is not yet available for purchase, it is scheduled for release in late summer. Norbauer & Co's Seneca represents new standards in keyboard design. Her ... >>

The world's tallest astronomical observatory opened 04.05.2024

Exploring space and its mysteries is a task that attracts the attention of astronomers from all over the world. In the fresh air of the high mountains, far from city light pollution, the stars and planets reveal their secrets with greater clarity. A new page is opening in the history of astronomy with the opening of the world's highest astronomical observatory - the Atacama Observatory of the University of Tokyo. The Atacama Observatory, located at an altitude of 5640 meters above sea level, opens up new opportunities for astronomers in the study of space. This site has become the highest location for a ground-based telescope, providing researchers with a unique tool for studying infrared waves in the Universe. Although the high altitude location provides clearer skies and less interference from the atmosphere, building an observatory on a high mountain poses enormous difficulties and challenges. However, despite the difficulties, the new observatory opens up broad research prospects for astronomers. ... >>

NexFET with double-sided cooling 31.01.2010

Texas Instruments announced the release of the industry's first family of standard-mount, high-power MOSFETs that dissipate heat through both the bottom and top of the package for high-current DC/DC applications.

This design allows power system designers to efficiently remove heat from printed circuit boards in high voltage DC or AC applications. This makes it possible not only to increase the density of power supplies, but also to expand the range of supported current loads and increase the reliability of systems.

The improved package technology reduces the thermal impedance towards the top of the package from 10 to 15°C per 1W to 1,2°C/W, resulting in an increase in heat dissipation capacity of up to 80%.

Efficient two-way heat dissipation allows up to 50% more current through the transistor, giving designers the flexibility to use higher current processors without increasing the size of the final hardware. The industry-standard 5x6mm SON package simplifies design and reduces cost, saving 30mm2 of floor space compared to using two standard packages.

The DualCool NexFET family includes five positions: CSD16325Q5C, CSD16322Q5C, CSD16321Q5C, CSD16407Q5C, CSD16408Q5C.
