The Army’s strategic vision calls for transformation to a
full-spectrum Objective Force that can project overwhelming
military power anywhere in the world on extremely short
notice. It must be agile, versatile, and lethal, achieving its
objectives through the application of dominant maneuver,
precision engagement, focused logistics, information superiority,
and highly survivable combat systems.

Research Article Vision-Based Unmanned Aerial Vehicle Navigation Using Geo-Referenced Information
The U.S. Department of Defense (DoD) faces a tightening budget in the coming years. Despite the lean budget years, unmanned aircraft systems (UAS) are expected to be a priority. Due to their usefulness for intelligence collection in irregular warfare (IW) and counterinsurgency (COIN), UAS were quickly fielded and sent to theater
Thuật ngữ Hệ thống bay không người lái (UAS - Unmanned Vehicle Systems) được thế giới sử dụng khá phổ biến để thể hiện việc ứng dụngcác thiết bị bay không người lái (UAVUnmanned Aerial Vehicle) để giám sát bề mặt trái đất, thu nhận ảnh phục vụ công tác thành lập bản đồ. Ưu thế của công nghệ này chi phí thấp, hình ảnh thu được nhanh, thường xuyên với độ chính xác cao và dễ dàng tạo dữ liệu 3D đáp ứng đúng thời điểm yêu cầu thu nhận thông tin.
Submersibles are a large and nonhomogeneous group of vehicles that range from small unmanned autonomous vehicles such as Gavia and REMUS that can be carried by one or two men, to medium-large unmanned submersibles such as torpedoes, survey vehicles such as HUGIN and Blueﬁn, larger manned deep-diving vehicles such as the US Alvin and the Russian MIR up to naval diesel-electric submarines. With a few exceptions, all these use electrochemical power sources for propulsion.
William Weir, author of New Page Book's 50 Battles That Changed the World, takes another look at the history of warfare, focusing on the hardware that served those famous battles, as well as others not as glorious. Included are: * Individual weapons-from spears to the submachine gun. * Crew-served weapons-from battering rams to "Big Bertha". * Unmanned weapons-from punji stakes to "Bouncing Betty" landmines and trap guns.
Changes in technology and adversary behavior will invariably produce new threats that must be assessed by defense and homeland security planners, and a decision must be made about whether they merit changes in current defenses or the development of new defensive approaches. An example of such a novel threat is the
Vision plays a fundamental role for living beings by allowing them to interact with the environment in an effective and efficient way. The ultimate goal of Machine Vision is to endow artificial systems with adequate capabilities to cope with not a priori predetermined situations. To this end, we have to take into account the computing constraints of the hosting architectures and the specifications of the tasks to be accomplished, to continuously adapt and optimize the visual processing techniques. Nevertheless, by exploiting the low?cost computational power of off?the?...
This book contains 35 chapters written by experts in developing techniques for making aerial vehicles more intelligent, more reliable, more flexible in use, and safer in operation.It will also serve as an inspiration for further improvement of the design and application of aeral vehicles. The advanced techniques and research described here may also be applicable to other high-tech areas such as robotics, avionics, vetronics, and space.
The mission of the Office of Naval Research (ONR) is to maintain a close relationship with the
research and development community to support long-range research, foster discovery, nurture future
generations of researchers, produce new technologies that meet known naval requirements, and provide
innovations in fields relevant to the future Navy and Marine Corps. Accordingly, ONR supports
research activities across a broad range of scientific and engineering disciplines.
Unfortunately, the United States lags behind other countries in recognizing the importance of robotics
technology. While the European Union, Japan, Korea, and the rest of the world have made significant
R&D investments in robotics technology, the U.S. investment, outside unmanned systems for defense
purposes, remains practically non-existent.
Các bánh xe càng mũi hạ cánh ba bánh đã được cấu hình ưa thích cho các UAV. Các tính năng hấp dẫn nhất của loại hình này undercarriages là tính ổn định cao trong quá trình phanh, diễn tập trên mặt đất. Kết quả của nghiên cứu này chỉ ra rằng bộ phận hạ cánh
The past three decades have seen a number of less-than-successful efforts to develop high-altitude unmanned aerial vehicles. In 1994, the Defense Advanced Research Projects Agency, in conjunction with the Defense Airborne Reconnaissance Office, initiated an effort — designated the High-Altitude Endurance Unmanned Aerial Vehicle Advanced Concept Technology
United Nation Department of Human Affairs (UNDHA) assesses that there are more than 100 million mines that are scattered across the world and pose significant hazards in more than 68 countries. The international Committee of the Red Cross (ICRC) estimates that the casualty rate from landmines currently exceeds 26,000 persons every year.
