Robot crab

20.05.2020

A special robot crab will help to explore the seabed. Specialists from Italy have developed a unique robot to study the ocean floor. The robot, resembling a crab, can move along the bottom and can study underwater terrain that is difficult for conventional research drones.

Underwater robots for studying the bottom are not new to robotics, but fish-like machines are usually used for such tasks, which comes with some difficulties. For example, fish-like drones depend on the currents, and, accordingly, cannot remain stationary unless they compensate for the force of the current with the work of the engines. Plus, the lack of a stop makes it difficult to take bottom samples with floating drones.

Another disadvantage of floating robots is that it is difficult for them to get close to the difficult bottom. All these problems are solved if you use a crab robot that does not swim near the bottom, but walks on it. Such a machine was designed by the staff of the School for Advanced Studies named after St. Anne, a team led by Giacomo Picardi.

“We decided not to invent what nature has already invented, and to take as a basis the method of movement used by crabs. Our SILVER2 underwater vehicle is in many ways similar to these creatures,” say the creators of the robot, noting that the device can carry a whole range of scientific tools, drills and manipulators, cameras, and so on.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

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, ... >>

Children and noise 02.01.2003

Recently in Munich (Germany) the old airport was closed and at the same time a new one was opened in another part of the city. This case was used by psychologists in order to identify the impact of noise from jet liners on the mental activity of children.

326 children with an average age of 10 years old living near the old and new airports were studied. Six months before the airport moved to a new location and six months after the move, the children's ability to read, remember what they read, comprehend speech and concentrate was tested.

It turned out that prolonged exposure to noise significantly worsens these indicators. One consolation: six months after the roar of jet engines stopped, the children freed from it caught up with their peers in their abilities.
