Jeans sewing robots

19.12.2022

According to experts, in the foreseeable future, many manufacturing operations will be subjected to automation, which implies monotonous manual labor, but the big problem for the creators of robots is still their inability to handle flexible materials of arbitrary shape. Siemens engineers have found a way to train robots to sew jeans by treating the fabric with a special compound.

Since 2018, relevant experiments have been carried out by Siemens and Levi's. The problem of automation in this industry escalated in the midst of a pandemic, when interruptions in logistics deprived American consumers of the opportunity to receive clothes in sufficient quantities from countries where core production has traditionally been concentrated in recent years.

Robotic arms are difficult to process fabrics that can have different thicknesses and textures, as well as constantly changing shape in the process. Siemens began its experiments in this area with the creation of robots that can process all types of flexible materials, including the thinnest wires for electronics. Later, the realization came that it makes sense to think about automating the manufacturing process of jeans, since they are made from a fairly dense and rigid fabric. The capacity of the clothing market reaches $1,52 trillion a year, so investments in automation can justify themselves at least in a situation where it is necessary to localize production in countries with a high level of wages for workers.

Siemens has found a partner in the young company Sewbo, which proposes the use of a special impregnation for denim, which temporarily increases the rigidity of the material. This property change makes it possible to simplify the processing of the material by robots. The special composition is washed out without residue during further washing of the jeans. Pants of this type are in any case washed during the production process, so the technology becomes slightly more complicated.

The implementation of such solutions also has a social aspect, which in the case of clothing production will be difficult to level. Studies have shown that the replacement of workers by robots does not have the best effect on the lives of the former. Participants in tests of robots developed by Siemens confirm that staff dissatisfaction with automation processes was sometimes expressed even with threats of physical violence.

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 ... >>

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, ... >>

Li-ion battery with water instead of electrolyte 13.12.2021

Researchers at the Yokohama National University of Japan have created a prototype lithium-ion battery with metastable and nanosized oxides based on molybdenum, which uses water as an electrolyte solution. This prototype is durable, fast-charging, and non-flammable.

Also, the test sample of the battery has "better ionic conductivity, environmental friendliness and high safety" compared to conventional ones. Even after 2 charge-discharge cycles, its capacity dropped by less than 30%.

The work of Japanese researchers paves the way for the development of high-energy, durable and safe batteries. But the main disadvantages of the latter are a low level of productivity and the possibility of using only under low voltage conditions, since water is destroyed at a high voltage level.

The specific gravity of energy (performance indicator) - a "water" battery is about half that of a conventional one. Therefore, for the production of batteries, a larger case size would have to be used.

"We have a safer battery with a long life that is expected to be used in practice, although the voltage is slightly lower [than required for commercial devices]," said Naoaki Yabuuchi, professor of chemistry at Yokohama National University.

Japanese researchers believe that their development may well be put into production within three years and even find application - for the accumulation of solar and wind energy, as well as in electric vehicles with a short range.
