Boston Dynamics Spot Robot

20.06.2020

The four-legged robot Boston Dynamics Spot went on sale starting at $74500.

Boston Dynamics has previously repeatedly demonstrated the usefulness of its four-legged Spot robot. The robot dog has been used to triage patients suspected of having COVID-19, herd sheep and farm.

In all of these cases, the robot was provided on a short-term lease under the Boston Dynamics Early Adopter Program. But now the situation is changing, and companies in the US have the opportunity to own the Spot robot. The Robot Dog is intended for commercial and industrial use, and orders are subject to Boston Dynamics terms and conditions that require the "useful use" of the robots.

The robots will be available through online sales, and interested parties can contact Boston Dynamics for pricing. Note that the version of Spot Explorer, created for developers who want to work with Spot, is priced at $74500. Additional batteries and modules such as LIDAR can cost between $4620 and $18450, respectively.

"At Boston Dynamics, we've spent decades building and refining robots with advanced mobility, agility and intelligence because we believe that nimble robots can solve a wide range of real-world problems," said Mark Reiber, chairman and founder of Boston Dynamics. "The combination of Spot's sophisticated software and high-performance mechanical design allows the robot to perform tasks that are difficult or dangerous for humans. Now you can use Spot to improve human safety in environments and tasks where traditional automation has failed to achieve success."

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, ... >>

Treatment of infections with electric current 03.11.2019

The original method, developed by scientists from the Swanson School of Engineering (SSOE) at the University of Pittsburgh (USA), is designed to treat infections caused by metal implants. The researchers suggest using electrochemical therapy to increase the ability of antibiotics to kill microbes.

Titanium has many properties that make it a suitable material for implants: low density, high stiffness, high biomechanical strength-to-weight ratio, and corrosion resistance. Today, different types of implants are made from titanium: from dental to joint prostheses. However, there is a persistent problem with metal implants: their surface is an ideal place for germs to accumulate, causing chronic infections and inflammation in the surrounding tissue. So, about five to 10 percent of dental implants fail and must be removed within 10-15 years so that the infection does not spread to the blood and other organs.

Added to this is the "crisis of antibiotics": many microbes develop resistance to certain drugs. Scientists at the University of Pittsburgh have found a way to help antibiotics fight infectious diseases.

The essence of their method is that a weak electric current is passed through a metal implant. The charge damages the cell membrane of the microbe attached to the implant, while not damaging the surrounding healthy tissue. Damage increases the permeability of the bacterial cell, making the microbe more susceptible to antibiotics. Most antibiotics usually target cells that will proliferate and bypass dormant, dormant microbes - which can cause infections to recur. Electrochemical therapy causes stress in all microbial cells, including sleeping ones.

The researchers tested their technology against Candida albicans (C. albicans), one of the most common and harmful fungal infections associated with dental implants.
