DJI's new Mavic Air 2 folding-style drone is a huge improvement over the previous model--so much so that for most people, this is the perfect drone. The Mavic Air 2 is the middle child in DJI's consumer drone lineup, sitting between the smaller, lighter, but less capable Mavic Mini, and the more powerful, more capable, but also more expensive, Mavic 2. If you're just getting started with drones, the less expensive Mavic Mini (8/10 WIRED Recommends)--my previous top pick for most people--might be a better buy. That said, the Air 2 offers better collision avoidance systems, higher quality photos and video, and a wide assortment of automated flight features that newcomers and seasoned vets alike can appreciate. The Mavic Air 2 is slightly bigger than its predecessor, at least on paper. The folding design remains compact, and at 1.3 pounds, the drone is plenty portable.
Owing to small size, sensing capabilities and autonomous nature, the Unmanned Air Vehicles (UAVs) have enormous applications in various areas, e.g., remote sensing, navigation, archaeology, journalism, environmental science, and agriculture. However, the unmonitored deployment of UAVs called the amateur drones (AmDr) can lead to serious security threats and risk to human life and infrastructure. Therefore, timely detection of the AmDr is essential for the protection and security of sensitive organizations, human life and other vital infrastructure. AmDrs can be detected using different techniques based on sound, video, thermal, and radio frequencies. However, the performance of these techniques is limited in sever atmospheric conditions. In this paper, we propose an efficient unsupervise machine learning approach of independent component analysis (ICA) to detect various acoustic signals i.e., sounds of bird, airplanes, thunderstorm, rain, wind and the UAVs in practical scenario. After unmixing the signals, the features like Mel Frequency Cepstral Coefficients (MFCC), the power spectral density (PSD) and the Root Mean Square Value (RMS) of the PSD are extracted by using ICA. The PSD and the RMS of PSD signals are extracted by first passing the signals from octave band filter banks. Based on the above features the signals are classified using Support Vector Machines (SVM) and K Nearest Neighbor (KNN) to detect the presence or absence of AmDr. Unique feature of the proposed technique is the detection of a single or multiple AmDrs at a time in the presence of multiple acoustic interfering signals. The proposed technique is verified through extensive simulations and it is observed that the RMS values of PSD with KNN performs better than the MFCC with KNN and SVM.
Sci-fi movies have created an impact on our minds that using robots in our life is a very bad idea. From The Terminator to The Matrix, almost every Hollywood movie shows that robots took control over humanity. Even RUR, the 1920s Karel Capek play introduced the term "robot,". Despite the cinematic warnings robots have moved from fiction stories to an important piece of modern world arsenal. Now the developed world is also debating on the point to use develop killer robots and machine to save human life.

Check out what's clicking on Foxnews.com A squadron of drones flying over the Midwest every night for nearly two weeks have left both residents and officials wondering who's flying them and what purpose they are serving, a report said Sunday. In the past week, three more rural counties have experienced nightly flyovers from the northeast corner of Colorado to at least one county in neighboring Nebraska, the Denver Post reported. Sheriffs in Lincoln, Washington and Sedgwick counties say their offices have been inundated with calls this week about the devices, the newspaper reported.
If I had told you in 2010 that one day you'd be able to take photos and videos with a flying camera that would take off from the ground, follow your directions as it soared into the skies and miraculously returned back, you might have thought I was pretty crazy. As did an app that could sense where you were and get a car to you within minutes for a ride. And a small box that connected to the TV and changed how we view entertainment forever. Yup, the "10s" were pretty mind-blowing for tech. So enjoy, as we run them down in the final 2019 edition of the Talking Tech newsletter.

Trooper John Jones used his drone to locate River, a 3-year-old Australian Shepherd, in a wooded area in Brown County. The dog and a driver were traveling on State Highway 57 on Friday when a deer darted onto the road, causing the unidentified driver to swerve and crash into a median, the Wisconsin Department of Transportation (DOT) said.
Artificial intelligence (AI) has the potential to deliver significant social and economic benefits, including reducing accidental deaths and injuries, making new scientific discoveries, and increasing productivity. However, an increasing number of activists, scholars, and pundits see AI as inherently risky, creating substantial negative impacts such as eliminating jobs, eroding personal liberties, and reducing human intelligence. Some even see AI as dehumanizing, dystopian, and a threat to humanity. As such, the world is dividing into two camps regarding AI: those who support the technology and those who oppose it. Unfortunately, the latter camp is increasingly dominating AI discussions, not just in the United States, but in many nations around the world. There should be no doubt that nations that tilt toward fear rather than optimism are more likely to put in place policies and practices that limit AI development and adoption, which will hurt their economic growth, social ...
In'The Terminator' series of action films starring Arnold Schwarzenegger, a cybernetic organism (cyborg) is programmed from the future to go back in time and kill the mother of the scientist who leads the fight against Skynet, an artificial intelligence system that will cause a nuclear holocaust. Terrifying and at times comical ("I'll be back", "Make my day") The Terminator cyborg was among the first presentations of artificial intelligence (AI) to a global audience. While numerous facets of AI have been developed over the past couple of decades, all with positive outcomes, the fear of AI being programmed to do something devastating to the human race, of computers "going rogue", continues to persist. On the other hand, AI holds tremendous potential for benefiting humanity in ways we are only just starting to recognize. This article gives an overview of artificial intelligence including some of its most interesting manifestations. The first step is defining what we mean by artificial intelligence. One definition of AI is "the simulation of human intelligence processes by machines, especially computers." Such processes include learning by acquiring information, understanding the rules around using that information, employing reasoning to reach conclusions, and self-correcting.
