Directory / Personal transport: land, water, air

This original design of the propeller was proposed by our reader from Volgodonsk, a student of the technical school Andrey Stativka. The author called his model a walker. Having familiarized yourself with the device of the vessel, you will be convinced that this unusual name was given to it quite deservedly.

Shagoplav

The propulsion device is clear from the figure. On two S-shaped brackets, reminiscent of bicycle pedals, two strips of dense rubber are stretched, to which rigid plastic or thin sheet metal blades are glued. Think for yourself how to fix the shoulder blades so that in the water they work like oars, without bending in the direction opposite to the movement. On the other hand, the shoulder blades, on the contrary, should bend freely - then, having left for land, the car will turn into a kind of walker.

Shagoplav

We have described the device of only one mover of the walker - on the other side of the hull it will look exactly the same. Brackets are curved from steel wire. Their front pair is united through the housing, making up one whole, and the rear, leading one, is connected to the shaft of the microelectric motor gearbox, as shown in the figure. In addition to the microelectric motor with a gearbox, a battery is also located inside the case.

The body of the model can be made independently or taken ready from any failed toy. We do not say anything about the size and number of blades - it depends on the dimensions and weight of the vessel. Try to keep this weight smaller, otherwise your walker will swim too slowly, and it may even refuse to “walk” at all.

And the last. As you can see, the walker can only move in a straight line... Guess what else you have to think about?

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

Smart guide vest for the visually impaired 24.01.2022

The Swiss company Biped presented a "smart" vest that uses autonomous driving technology that allows visually impaired or blind people to detect obstacles in the user's path a few seconds before a collision with them.

Called Biped.ai, the wearable has a minimalist design, with built-in 3D cameras that can be paired with headphones or Bluetooth headphones to alert users to the location of obstacles around them.

The vest sits on the shoulders and, thanks to its 3D cameras, can detect and predict the trajectories of all surrounding elements a few seconds ahead, like an autonomous car. It generates XNUMXD audio feedback to alert users to the position of important elements around them.

The Biped.ai vest can recognize more than 10 types of objects, but only filters important counter objects. For example, the device will warn the user if it detects a dangerous obstacle, such as a bicycle 12 meters ahead, but will ignore a closer object that it does not consider to pose a risk of collision.

The device then filters relevant information about oncoming objects and alerts the wearer with "spatial sounds" - sounds that are superficially similar to the real-life version of the sound.

The smart vest is equipped with a removable battery that lasts more than six hours, which means that the user can use it for most of their day. It can also connect to the GPS on a smartphone and give navigational instructions to the wearer via audible cues.

Biped.ai is also designed to work at night and in dark places as the obstacle avoidance software uses high quality infrared cameras that work in all conditions.

The device will be available in Europe from September 2022. The brand produces vests in different sizes that are suitable for people over 1,5 meters tall.
