Researchers at Harvard University have recently devised a system based on Wi-Fi sensing that could enhance the collaboration between robots operating in unmapped environments. This system, presented in a paper pre-published on arXiv, can essentially emulate antenna arrays in the air as a robot moves freely in a 2-D or 3D environment.

“The main goal of our paper was to leverage arbitrary 3D trajectories for a (UAV or UGV) equipped with an on-board estimation sensor,” Ninad Jadhav, one of the researchers who carried out the study, told TechXplore. “This allows a Wi-Fi-signal-receiving robot to estimate the spatial direction (in azimuth and elevation) of other neighboring robots by capturing all the wireless signal paths traveling between the transmitting and receiving robot (which we call AOA profile). Additionally, we also characterized how the trajectory shape impacts the AOA profile using Cramer Rao bound.”

In their previous studies, Jadhav and his colleagues focused on robot collaboration scenarios in which the robots followed 2-D trajectories with a limited set of geometries (e.g., linear or curved). The new system they created, on the other hand, is applicable to scenarios where robots are moving freely, following a wider range of trajectories.

The Man Said That His Country Has Been In Existence For 1000 Years And Was A Little Puzzled Why His Country Was Called Andorra On The Map.

It was July 1954 when a smartly dressed man arrives at Haneda Airport in Tokyo, Japan. Much like other passengers, he makes his way to customs. But whatever happened from this point onwards have left all puzzled and concerned. When questioned by the customs officers, the mysterious passenger said he was from Taured, also referred to as Taured Mystery. The mystery man claimed that it was the third time he was visiting Japan from his country. But, to the surprise of officers, they couldn’t find any country named Taured. The primary language of the man, described as Caucasian looking with a beard, was French. However, she was purportedly speaking Japanese and many other languages as well.

Officers were perplexed because they had never heard about any such country. The passport of the man was issued by of course the Taured. The passport looked authentic but the place was not recognized.

Location of Taured.
The man was then given a map and asked to point out his country. He immediately man pointed to the area occupied by the Principality of Andorra is at the border of France and Spain. The man said that his country has been in existence for 1000 years and was a little puzzled why his country was called Andorra on the map. The man argued with the customs officers for long and refused to give in.

What Is The Mystery All About?
He was also carrying currencies of different countries, probably because he had made several business trips. The mystery man shared other details like the company for which he was working and the hotel where he stayed. Officials find out that the company which he mentioned existed in Tokyo but not in Taured. Similarly, the hotel he mentioned did exist but hotel employees informed them that no such booking was made. This prompted officers to take the man in custody for further interrogation. Officers were suspicious that he might be some criminal and confiscated his documents and personal belongings. The officers put the mystery man in a nearby hotel whilst they conducted their investigation.

Mystery Man Vanishes Amid Tight Security.
To ensure that the mystery man didn’t escape, two guards were placed on the door. It must be mentioned that the hotel room in which he was staying only had one entry and exit point. But to everyone’s surprise, the man vanished the next morning. Not only that, but all his personal documents had also disappeared. A search was launched to find the man but in vain. The thing that was troubling investigating officers was that he was put up in a room high up in the multi-storey hotel building with no balcony.

Unexplained Phenomena.
Some people argued that the mystery man was indeed from Taured but the country happens to be in another universe and somehow passed through a parallel dimension and ended up at Haneda Airport. Another theory is that the mystery man was a time traveller and had mistakenly landed at the airport. Above all this, there are people who claim that it’s just an elaborate internet hoax.

SpaceX aims to provide Starlink satellite broadband internet service worldwide. “With performance that far surpasses that of traditional satellite internet, and a global network unbounded by ground infrastructure limitations, Starlink will deliver high speed broadband internet to locations where access has been unreliable, expensive, or completely unavailable,” the company’s website states, “Starlink is now delivering initial beta service both domestically and internationally, and will continue expansion to near global coverage of the populated world in 2021.” SpaceX is currently providing Starlink beta service to select customers living in northern United States, Canada, and United Kingdom. To receive updates about when service will be available in your area sign-up via Starlink.com.

Starlink customers receive broadband internet connection from the satellites in space via a Starlink Kit which includes a phased-array antenna dish, Wi-Fi router, along with power and mounting equipment. The kit is priced at $499 USD, with a monthly service fee of $99 USD. SpaceX has approval from the Federal Communications Commission (FCC) to operate 1 Million dish antennas for customers in the United States. In July, the company submitted a new FCC request to operate 5 Million additional dish terminals in the U.S. – “SpaceX Services requests this increase in authorized units due to the extraordinary demand for access to the Starlink non-geostationary orbit satellite system,” the company wrote in the FCC filing last year. The FCC has not approved the request yet.

Reviews.org, a team that reviews technology products online, conducted a asking 500 Americans if they would switch internet provider once SpaceX’s Starlink broadband service enters the public telecommunications market. “Starlink internet is perfect for those who feel stuck with slow speeds from their internet provider –especially in rural areas where building out cable and fiber networks either takes a long time or is less likely to provide adequate coverage,” Reviews.org wrote in its website. According to the Review.org results, 51% of Americans would switch to SpaceX Starlink Internet service. “51% of internet users say they plan to sign up for the Starlink beta once it becomes available to them. While only 5% of Americans currently use a satellite internet connection, 64% of respondents say Starlink’s rollout would make them reconsider their satellite internet stance,” Review.org representatives wrote in the publication, “55% of non-satellite internet users say they’d switch to Starlink’s satellite internet service at a higher cost if it resulted in faster internet speeds for their household,” they stated. The organization compiled a graphic with more details about the their, pictured below.

The result was a bizarre, Lego-like human tissue that replicates the basic circuits behind how we decide to move. Without external prompting, when churned together like ice cream, the three ingredients physically linked up into a fully functional circuit. The 3D mini-brain, through the information highway formed by the artificial spinal cord, was able to make the lab-grown muscle twitch on demand.

In other words, if you think isolated mini-brains—known formally as brain organoids—floating in a jar is creepy, upgrade your nightmares. The next big thing in probing the brain is assembloids—free-floating brain circuits—that now combine brain tissue with an external output.

The end goal isn’t to freak people out. Rather, it’s to recapitulate our nervous system, from input to output, inside the controlled environment of a Petri dish. An autonomous, living brain-spinal cord-muscle entity is an invaluable model for figuring out how our own brains direct the intricate muscle movements that allow us stay upright, walk, or type on a keyboard.

The Chinese capital may be the most well-positioned to help China’s satellite internet ambitions. Ultimate Blue Nebula’s Lan said private satellite manufacturers and space transport providers based in Beijing could make up as much as 80 per cent of the nascent Chinese satellite internet industry’s overall supply chain.

The Chinese capital is already home to a comprehensive supply chain for satellite manufacturers and space transport providers.

We are fascinated by machines that can control cars, compose symphonies, or defeat people at chess, Go, or Jeopardy! While more progress is being made all the time in artificial intelligence (AI), some scientists and philosophers warn of the dangers of an uncontrollable superintelligent AI. Using theoretical calculations, an international team of researchers, including scientists from the Center for Humans and Machines at the Max Planck Institute for Human Development, shows that it would not be possible to control a superintelligent AI. Their study is published in the Journal of Artificial Intelligence Research.

Suppose in the not-too-distant future that a research team builds an AI system with intelligence superior to that of humans, so it can learn independently. Connected to the Internet, the AI would have access to all of humanity’s data. It could replace existing programs and take control of all machines globally.

Would this produce a utopia or a dystopia? Would the AI cure cancer, bring about world peace, and prevent a climate disaster? Or would it destroy humanity and take over the Earth?
