Xiaomi's CyberDog - An alternative to Boston Dynamics $70,000 robot dog

 Xiaomi's CyberDog is a robot dog that costs 60 times less than Boston Dynamics' robot dog. 


Xiaomi's CyberDog

The Chinese firm unveils its first robot, clearly inspired by Boston Dynamics' work over the years.

Spot, Boston Dynamics' robot dog, already has competitors, and it is made in China at a fraction of the cost of the American model.

It's called CyberDog, and it's Xiaomi's most recent development. It moves on all fours, just like Spot, and has some of the same talents as Spot, such as the ability to back flip.

It moves a little more slowly than the rivals. It moves about 3.2 meters per second, compared to roughly 4 meters per second for Spot. On paper, the differences appear to be minor.

CyberDog, like Spot, has many sensors and cameras to assist it navigate its environment, and three USB-C connectors and an HDMI port allow it to be expanded with various modules.

The pricing is the most significant difference. At the current currency rate, Spot, which is already being deployed on a trial basis by numerous security agencies and even some countries' armies, costs around 65,000 euros.

Instead, Xiaomi will sell the first 1,000 CyberDog versions for around 1,315 euros, which is 49 times less.

In fact, the business touts it as a robot that can be used as a pet in the launch press release, with the ability to understand and respond to voice orders. The built-in sensors of CyberDog also allow it to track a face in a crowd.

However, similar to Boston Dynamics' Spot, Xiaomi sees CyberDog as a platform rather than a finished product. "Xiaomi fans, engineers, and robotics aficionados to explore the tremendous possibilities of CyberDog," according to the press release.

CyberDog's software is also 100 percent open source, according to the business, which wants to build a community of developers around the product from which to evaluate further robotics releases.

Robots with artificial muscles will not appear like robots in the future

Thanks to low-cost artificial muscles, robots may not appear like robots in the future.

Despite the fact that the Uncanny Valley theory suggests that humans reject robots that look too much like them, researchers have worked hard to produce aspects that make these robots look as human as possible, including skin, hair, and even movements and facial expressions. However, there is still a long way to go until a robot no longer looks like a robot and can blend in with a crowd.

With this in mind, MIT researchers have developed a synthetic muscle made of plastic nylon, which will allow us to create fake human tissues and hence create robots that appear remarkably similar to us.

Low-cost mass production is the key.

The concept of creating artificial muscles is not new; we've already seen several projects that rely on carbon nanotubes or various alloys that adapt to various shapes and designs. The issue here, however, is cost; all of these projects are expensive, and large-scale production is virtually impossible because few companies would be willing to pay for them.

This development is based on the idea of having something accessible, where they discovered that nylon fiber has unique characteristics capable of assisting in the manufacture of these muscles, because the key is that when heated, these fibers contract in length but expand in diameter, causing them to bend depending on the heat applied.

Due to the fact that the heat source can range from electrical resistance to chemical reactions and even laser, it is possible to control the amount of heat and the area of application, allowing one area to contract while the other remains fixed, as well as the fact that the heat source can be from an electrical resistance to chemical reactions and even laser, its applications are very broad and can serve in a variety of scenarios and contexts.

In the first tests, it was discovered that this fiber is surprisingly elastic, can last over 100,000 cycles, and can contract up to 17 times per second, making it an ideal material not only for robots, but also for industrial applications where materials that contract and adapt to a structure are required to reduce friction, such as airplanes or cars, clothing, and even self-adjusting catheters for insulin pumps. However, their primary focus thus far has been to develop biomimetic muscles for robots.

Lake And River On Mars Discovered by The Exploration Perseverance rover

 NASA has confirmed that Mars once had a lake and a river thanks to the Perseverance rover.
Scientists aim to learn more about the red planet's climatic and hydrological evolution when the Perseverance rover explores that barren, wind-eroded depression.

Jezero Crater on Mars was formerly a calm lake fed by a little river that began to endure rapid, violent floods after an abrupt shift in climate pushed massive rocks from tens of kilometers upstream to the lakebed, where they currently remain.

The initial study of photos obtained by NASA's Perseverance rover has confirmed what scientists had suspected: the Jezero crater, which is now a dry, wind-eroded depression, was once a peaceful Martian lake.

The crater was chosen as the rover's landing site because satellite photographs revealed that it resembled river deltas on Earth. The findings were published in the journal Science on Thursday.

Scientists from NASA and the French CNRS spearheaded the investigation, which included Jess Martinez-Frias of the Institute of Geosciences (IGEO).

"These Perseverance geological analyses of Martian rocks and outcrops demonstrate their value for defining ancient Martian habitats (paleoenvironments) and establishing their links with water and habitability conditions," Martnez-Fras told the EFE news agency.

When you look at the photographs, according to Benjamin Weiss, an MIT researcher and co-author of the study, "Basically, you're looking at a massive desert environment. The most desolate location on the planet. Despite the fact that there isn't a drop of water around, there is evidence of a totally different history. Something significant occurred in the planet's history."

Last February, the rover landed on the floor of Jezero Crater, just under two kilometers from the western side, but two of its cameras, the Mastcam-Z and the SuperCam Remote Micro-Imager (RMI), captured high-resolution images of the crater and a small mound known as the Kodiak butte, while NASA engineers remotely checked the rover's instruments.

When the rover returned them to Earth, NASA's Perseverance science team analyzed and merged them, revealing various sediment beds.

The researchers determined that the sediments were not formed by wind, but rather by water movement in a lake, flooding, or other geologic processes, by measuring the thickness, slope, and lateral extent of each layer.

"The rover was able to solve one of the huge unknowns, which was that this crater was once a lake, without having to land anywhere. It was always an unknown until we actually landed there and confirmed that it was a lake "Weiss acknowledges this.

The researchers noticed enormous boulders and boulders embedded in the younger, highest strata of the delta when they looked at photos of the main outcrop; some were up to a meter broad and weighed several tons.

The scientists came to the conclusion that the massive rocks must have come from beyond the crater or many kilometers upstream, and were carried to the lakebed by a flash flood with a flow rate of up to 9 meters per second and a water volume of up to 3,000 cubic meters per second.

These massive boulders in the delta's upper levels are the most recently deposited material, resting on layers of older and finer sediments, indicating that the ancient lake was fed by a gently flowing river for much of its history.

Over time, the crater experienced flash floods that deposited big rocks in the delta, and subsequently the lake dried up due to a climatic change that is unknown why it occurred. The wind ravaged the ground over billions of years, creating the crater we see today.

Scientists want to learn more about Mars' climatic and hydrologic evolution as the rover explores the crater, because if Jezero was once a lake, its sediments may retain remnants of ancient aquatic life.

Perseverance will hunt for areas to collect sediments and samples that will be sent back to Earth for scientists to examine for Martian bio-signatures on its next mission.

Venice Underwater robots monitoring climate change

 

Underwater robots

Climate change, pollution, mass tourism, and invasive species all have a negative impact on huge lake areas like Venice. A swarm of autonomous aquatic robots is being used by an EU initiative to monitor and counteract the effects of these elements underwater. Researchers will be able to conduct several activities at once and from multiple locations, which will aid in the fight against climate change.

It is impossible to discuss Venice without mentioning its canals. However, you should keep an eye out for the aquatic robots the next time you take a romantic gondola ride around this metropolis. That's because a group of researchers from the subCULTron project, which is financed by the European Union, has "launched" a swarm of more than 120 aquatic robots into Venice's lagoon and canals.

While it may sound like something out of a science fiction film, these self-driving robots are an important part of the city's efforts to combat climate change and pollution.

"Climate change, pollution, mass tourism, and invasive species are only some of the concerns facing the Venice lagoon," says Ronald Thenius, a researcher at the University of Graz (Austria) and a member of the subCULTron project. New issues necessitate new answers, and we believe that using robots is the most effective method to handle these unique difficulties."

Underwater robots in a swarm

The project's major purpose was to develop a cutting-edge instrument for monitoring the underwater habitats of big lake basins like Venice. The subCULTron system, on the other hand, was designed to provide spatially distributed monitoring, unlike traditional monitoring systems. This means it had to be able to measure multiple sites at the same time and over a long period of time. The researchers accomplished this by using a massive swarm of relatively small and affordable robots.

"This'swarm method' contrasts significantly with the more frequent practice of utilizing a large, expensive robot," Thenius says. Our technology makes it easier for the robot swarm to behave autonomously and decentralized by allowing us to acquire several measurements at the same time and from different locations."

According to Thenius, the robotic system's unique self-organizing architecture allows it to take measurements as well as react. If the algorithm judges that a particular measurement is no longer required, elements of the swarm can be automatically relocated to a more interesting location or the sampling rate in other areas changed.

Water lilies, mussels, and fish

aMussels (artificial mussels), aFish (artificial fish), and aPads (artificial pads) make up the subCULTron system (artificial water lilies). "The aMussels operate as the system's collective long-term memory," Thenius continues, "allowing information to persist beyond the runtime of the other types of robots." The natural habitat of lake fish, as well as other biological agents such as algae and bacteria, are monitored by these artificial mussels."

The aPads, on the other hand, float on the water's surface like genuine water lilies. These robots serve as the system's interface with human society, supplying the swarm with energy and information from the outside world. Between these two layers swim the aFish, which are fake fish that travel through the water, monitoring and inspecting the surroundings and transmitting the data to the mussels and artificial water lilies.

"As soon as the swarm "decides" that a site warrants greater attention, many aMussels emerge to be carried to the new site of interest through the aPads," Thenius explains. As a result, the swarm will be able to wander around the lagoon and examine various occurrences on its own."

Aside from the robots themselves, another significant outcome of the study is the novel method of powering the robots: sludge. "The unique proof of concept that an autonomous robot can be fuelled purely by microbial fuel cells is a big accomplishment," adds Thenius.

A microbial fuel cell is a bioelectrochemical device that uses bacteria and a high-energy oxidant, such as oxygen from a pond bed, to generate an electric current.

"Although this technology has been tried in several laboratories before, subCULTron was the first study to demonstrate that it can be used in the field by autonomous robots," Thenius says. This achievement paves the way for a plethora of new and exciting technologies and advances.

How artificial intelligence can help combat climate change

How artificial intelligence may assist in the fight against climate change


 


With the epidemic, people are more aware of the implications of climate change. Extreme weather occurrences are having an increasing impact on human health, economy, and business. There have been 7,348 big disasters in the last two decades, claiming 1.23 million lives, affecting 4.2 billion people, and costing $2.97 trillion in worldwide economic damages, with 2019 seeing the largest CO2 emissions in human history.

Artificial intelligence, in this context, offers considerable benefits for businesses in terms of reducing greenhouse gas (GHG) emissions, increasing efficiency, and reducing waste. GeSI technology has the potential to reduce 9.7 times more carbon emissions than it emits, according to the Global e-Sustainability Initiative. 

With effective use cases such as tracking GHG emissions and monitoring GHG leakage at industrial sites, as well as utilizing AI to improve the energy efficiency of industrial facilities and processes, AI's adoption to combat climate change is expanding. As an example, consider the following:

- Monitoring greenhouse gas emissions and leakage at industrial locations.

- Improving the efficiency of industrial facilities and processes in terms of energy use.

- Artificial intelligence (AI) for developing innovative products that reduce waste and pollution during prototype, manufacturing, and use

- Artificial intelligence (AI) for inventory management - enhancing demand forecasting and decreasing food, product, and raw material waste

- Fleet management and route optimization for retail, automotive, and consumer goods firms

Climate AI: How Artificial Intelligence Can Drive Your Climate Action Strategy, a new report from Capgemini Research Institute, polled 800 industry executives and 300 AI and climate change specialists, as well as interviewing more than 40 industry executives and experts. The findings of the paper show that AI-enabled use cases have already helped enterprises reduce GHG emissions by 13% and improve energy efficiency by 11% in the last two years.

According to the paper, AI-enabled use cases have the potential to assist enterprises in meeting between 11 and 45 percent of the Paris Agreement's "economic emissions intensity" targets by 2030. For example, AI-enabled use cases in the automobile sector have the potential to achieve 8 percentage points of the 37 percent (almost one-fifth) reduction required by 2030 under the Paris Agreement targets.

Artificial intelligence is also being use to design innovative goods that reduce waste and emissions during prototype, manufacture, and use. By enhancing demand planning, AI is helping to reduce food and raw material waste. It is also being successfully deployed for route optimization and fleet management in the retail, automotive, and consumer products industries.

Despite this promise, the 'Climate AI Champions,' or organizations who are successfully deploying climate AI, make up only 13% of the total survey sample. AI action through the development of dedicated technical and leadership teams to drive implementation is one of the strong characteristics of their management that stands out. 

Thus, compared to 36 percent of the others, 47 percent of champions have a dedicated leader for each climate goal and action, and 53 percent have a dedicated team to deploy technology solutions, compared to 42 percent of the rest.

One of the report's main recommendations is that sustainability teams be educated on AI's potential, as well as AI teams be educated on the importance of climate action. In addition, in order to fully fulfill AI's climate-action potential, organizations must:

Combat AI's harmful impact on the environment.

Educate their staff on the urgency of climate change and how artificial intelligence can help.

Lay the technological foundation for AI-assisted climate action.

Specific use cases should be scaled.

Collaborate with the ecosystem of climate change.

Make use of artificial intelligence to concentrate on reducing scope 3 emissions.

The Earth now shines less brightly than before

 

Earth
 

Researchers have discovered that the Earth no longer shines as brightly as it once did.
Observations of ashen light over decades show a progressive reduction.

According to a study published in Geophysical Research Letters last week, Earth is losing part of its brightness. Our world appears to have faded as a result of both human-caused and natural climate change. People, we can't have lovely things, can we?

The research looks at ashen light, which is light reflected off the Earth's surface and illuminates the Moon's surface weakly. The new findings are based on two decades of data collected by the Big Bear Solar Observatory with a special type of Moon-viewing telescope, and are known as Da Vinci's glow because Leonardo da Vinci was the first person to formally write about it. His research has come a long way since Da Vinci's day 500 years ago, and the new findings are based on two decades of data collected by the Big Bear Solar Observatory with a special type of Moon-viewing telescope.

When the Moon is waxing or waning, it is the finest moment to see the ashen glow. When you look at the Moon, you may see a faint outline in addition to the bright portion. The brightness of the Earth, which is caused by the Sun's light reflecting off our globe, produces that spectrum light.

The observatory is excellently situated to measure the ashen light over 40% of the world, which includes sections of the Pacific and North America. Between 1998 and 2017, data from around 800 nights revealed a tiny but significant decline in Earth's brightness. There were some year-to-year variations, but they were "modest, with a long-term reduction dominating the time series," according to the research.

Satellite data was used to determine what was causing the dimming. The ashen light is caused by varied amounts of reflectance in continents, ice, clouds, and the ocean. (Albedo refers to the reflectance of various surfaces.) The absence of clouds in the tropical Pacific, according to the research, is to blame for the Earth's dimming brightness. In a statement, Philip Goode, a researcher from the New Jersey Institute of Technology and principal author of the findings, said, "The reduction in albedo came as a surprise to us when we studied the latest three years of data after 17 years of practically flat albedo."

Onions sold in 37 states have been linked to a Salmonella outbreak in the United States.

Two solar cycles are included in the data because it spans 20 years. The Sun swings through 11-year cycles of increasing and decreasing activity, which is used by climate change deniers as an explanation. However, just as climate scientists have kindly pointed out that "no, that's not so," this study's researchers have done so as well.

They said, "Our results do not support an argument for any discernible imprint of direct or indirect solar activity mechanisms on the Earth's reflectance over the last two decades." To put it another way, it's not the Sun that's dimming; it's the Earth. Seriously, stop blaming the Sun; has it ever harmed you?

Instead, the evidence points to two possible perpetrators who may be working together. Temperatures have risen worldwide, especially in the oceans, as a result of climate change. This could be due to a decrease in cloud cover in the area. A change in the Pacific Decadal Oscillation, a natural climatic change that went into a warm phase after 2010 and might have the same effect on clouds, is also possible.

This may appear to be a little issue, but it is actually rather concerning. When the albedo of the Earth is reduced, more solar energy reaches the planet. Extra energy is trapped here in the form of heat due to greenhouse gases produced by burning fossil fuels. That's not good!

It may seem strange to research Earth's climate by measuring ashen light on the Moon. However, unlike Earth-facing satellites, which sometimes have equipment faults, monitoring ashen light is a relative measurement that allows for more consistent results, according to researchers. More research on Earth's brightness is needed, according to the scientists, because it's fascinating and strange enough to pique our interest.

The new discovery of a drop in ashen light adds to a long list of unusual climatic results. The Earth's crust is shifting in unexpected ways, and the planet's axis is wobbling in new ways. It's uncertain what else climate change will wreak havoc on, but we should brace ourselves for the unexpected.

Germany joins the new space race

 

Rocket Factory

 Several German projects are ready to compete in the space exploration business against heavyweights like SpaceX and Virgin Galactics.

Space exploration has been out of reach for most governments for decades due to the difficulties of getting beyond our planet. Most countries simply did not have the enormous finances required to send objects into space.

Despite the fact that more than 60 countries have a space program, just ten have succeeded in launching rockets beyond Earth on their own. However, technical advancements have reduced expenses, and the moment appears to be approaching when space and its offshoot activities, such as space tourism, will be more accessible.

The space and suborbital flight business is dominated by American companies such as SpaceX and Virgin Galactics, but other companies from across the world are not willing to miss out. Germany has just demonstrated that it will be a formidable rival in this race.

Three German projects are currently competing in the field of extraterrestrial exploration. The idea is to launch dozens of satellites, forming a network that will give Internet access and intelligent vehicle support.

Three companies from Germany are aiming for the top.

Last week, the Rocket Factory Augsburg successfully tested a satellite utilizing a staggered burn method. They would be able to carry 30% more payload aboard the spacecraft using this way. Until date, only American billionaire corporations like SpaceX (Elon Musk) and Blue Orgin had used this strategy (Jeff Bezos).

HyImpulse, situated in Baden-W├╝rttemberg, is another German business that has piqued the curiosity of all space exploration professionals. It recently completed its maiden engine test with wax-based gasoline in order to improve fuel economy.

The German firm that has piqued the public's interest has yet to conduct substantial experiments, although it is the most well-funded of the bunch. Isar Aerospace is supported by multibillion-dollar companies, including Lombard Odier, a Swiss bank. They intend to launch their first rocket, the "Spectrum," by 2022, with more than €150 million in finance.

These firms do not aspire to launch huge rockets like NASA or the European Space Agency (ESA). They want to do a lot of mini-launches on a regular basis. Rather than launching enormous quantities of supplies and many people into space, these mini-rockets would serve as space cabs. By 2027, the small space transportation market is expected to increase to more than €30 billion.

The director of Rocket Factory Augsburg, Joern Spurman, states, "We aim to create a Henry Ford moment." Before all of these businesses venture into space, now is the moment to draft a new space legislation to ensure that we do not conquer the stars, but rather live among them.
