Unmanned Surface Vehicles Of Israel
An uncrewed vehicle or unmanned vehicle is a vehicle without a person on board. Uncrewed vehicles can either be under telerobotic control—remote controlled or remote guided vehicles—or they can be autonomously controlled—autonomous vehicles—which are capable of sensing their environment and navigating on their own. It has been reported that the armed forces of more than 100 countries have approximately 170 different types of drones in service. Types There are different types of uncrewed vehicles: * Remote control vehicle (RC), such as radio-controlled cars or radio-controlled aircraft * Unmanned ground vehicle (UGV), such as the autonomous cars, or unmanned combat vehicles (UCGV) **Self-driving truck **Driverless tractor * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft, either fixed-wing or rotorwing, commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) **Medium ...

Unmanned Combat Aerial Vehicle
An unmanned combat aerial vehicle (UCAV), also known as a combat drone, fighter drone or battlefield UAV, is an unmanned aerial vehicle (UAV) that is used for intelligence, surveillance, target acquisition, and reconnaissance and carries aircraft ordnance such as missiles, anti-tank guided missiles (ATGMs), and/or Aerial bomb, bombs in hardpoints for drone strikes. These drones are usually under real-time human control, with varying levels of autonomy. UCAVs are used for reconnaissance, attacking targets and returning to base; unlike Loitering munition, kamikaze drones which are only made to explode on impact, or unmanned surveillance and reconnaissance aerial vehicle, surveillance drones which are only for gathering intelligence. Aircraft of this type have no onboard human pilot. As the Radio control, operator runs the vehicle from a remote terminal, equipment necessary for a human pilot is not needed, resulting in a lower weight and a smaller size than a manned aircraft. Many ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Uncrewed Spacecraft
Uncrewed spacecraft or robotic spacecraft are spacecraft without people on board. Uncrewed spacecraft may have varying levels of autonomy from human input, such as remote control, or remote guidance. They may also be autonomous, in which they have a pre-programmed list of operations that will be executed unless otherwise instructed. A robotic spacecraft for scientific measurements is often called a space probe or space observatory. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and risk factors. In addition, some planetary destinations such as Venus or the vicinity of Jupiter are too hostile for human survival, given current technology. Outer planets such as Saturn, Uranus, and Neptune are too distant to reach with current crewed spaceflight technology, so telerobotic probes are the only way to explore them. Telerobotics also allows exploration of regions that are vulnerable to contamination by Earth micro-organisms sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Underwater Glider
An underwater glider is a type of autonomous underwater vehicle (AUV) that employs variable-buoyancy propulsion instead of traditional propellers or Underwater thruster, thrusters. It employs variable buoyancy in a similar way to a profiling float, but unlike a float, which can move only up and down, an underwater glider is fitted with hydrofoils (underwater wings) that allow it to Gliding flight, glide forward while descending through the water. At a certain depth, the glider switches to positive buoyancy to climb back up and forward, and the cycle is then repeated. While not as fast as conventional AUVs, gliders offer significantly greater range and endurance compared to traditional AUVs, extending ocean sampling missions from hours to weeks or months, and to thousands of kilometers of range. The typical up-and-down, Sawtooth wave, sawtooth-like profile followed by a glider can provide data on temporal and spatial scales unattainable by powered AUVs and much more costly to sampl ...

Intervention AUV
Intervention AUV or I-AUV is a type of autonomous underwater vehicle. Its characteristic feature is that it is capable of autonomous interventions on the subsea installations, a task usually carried out by remotely operated underwater vehicles (ROVs) or human divers. Before I-AUVs Basic maintenance as well as repairs were traditionally done by human divers equipped with the appropriate pressure-resistant suits. Such operations were burdened with a high dependency on weather and involved direct hazards on humans. Due to slow exhaustion of the shallow oil sources, the oil wells An oil is any nonpolar chemical substance that is composed primarily of hydrocarbons and is hydrophobic (does not mix with water) and lipophilic (mixes with other oils). Oils are usually flammable and surface active. Most oils are unsatur ... were installed in deeper water (>500m of depth). This made diver operation less feasible due to heavy suits and higher associated risks. Beginning in the 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Underwater Vehicle
An autonomous underwater vehicle (AUV) is a robot that travels underwater without requiring continuous input from an operator. AUVs constitute part of a larger group of undersea systems known as unmanned underwater vehicles, a classification that includes non-autonomous remotely operated underwater vehicles (ROVs) – controlled and powered from the surface by an operator/pilot via an umbilical or using remote control. In military applications an AUV is more often referred to as an unmanned undersea vehicle (UUV). Underwater gliders are a subclass of AUVs. Homing torpedoes can also be considered as a subclass of AUVs. History The first AUV was developed at the Applied Physics Laboratory at the University of Washington as early as 1957 by Stan Murphy, Bob Francois and later on, Terry Ewart. The "Self-Propelled Underwater Research Vehicle", or SPURV, was used to study diffusion, acoustic transmission, and submarine wakes. Other early AUVs were developed at the Massachus ...

Remotely Operated Underwater Vehicle
A remotely operated underwater vehicle (ROUV) or remotely operated vehicle (ROV) is a free-swimming submersible craft used to perform underwater observation, inspection and physical tasks such as valve operations, hydraulic functions and other general tasks within the subsea oil and gas industry, military, scientific and other applications. ROVs can also carry tooling packages for undertaking specific tasks such as pull-in and connection of flexible flowlines and umbilicals, and component replacement. They are often used to do research and commercial work at great depths beyond the capacities of most submersibles and divers. Description This meaning is different from remote control vehicles operating on land or in the air because ROVs are designed specifically to function in underwater environments, where conditions such as high pressure, limited visibility, and the effects of buoyancy and water currents pose unique challenges. While land and aerial vehicles use wireless commu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unmanned Underwater Vehicle
Unmanned underwater vehicles (UUV), also known as underwater drones, are submersible vehicles that can operate underwater without a human occupant. These vehicles may be divided into two categories: remotely operated underwater vehicles (ROUVs) and autonomous underwater vehicles (AUVs). ROUVs are remotely controlled by a human operator. AUVs are automated and operate independently of direct human input. Classifications Remotely operated underwater vehicle Remotely operated underwater vehicle, Remotely Operated Underwater Vehicles (ROUVs) is a subclass of UUVs with the primary purpose of replacing humans for underwater tasks due to the difficult underwater conditions. ROUVs are designed to perform educational or industrial missions. They are manually controlled by an operator to perform tasks that include surveillance and patrolling. The structure of ROUVs disqualify it from being able to operate autonomously. In addition to a camera, actuators, and sensors, ROUVs often incl ...

Unmanned Surface Vehicle
An unmanned surface vehicle, unmanned surface vessel or uncrewed surface vessel (USV), colloquially called a drone boat, drone ship or sea drone, is a boat or ship that operates on the surface of the water without a crew. USVs operate with various levels of autonomy, from remote control to fully autonomous surface vehicles (ASV). Regulatory environment The regulatory environment for USV operations is changing rapidly as the technology develops and is more frequently deployed on commercial projects. The Maritime Autonomous Surface Ship UK Industry Conduct Principles and Code of Practice 2020 (V4) has been prepared by the UK Maritime Autonomous Systems Regulatory Working Group (MASRWG) and published by Maritime UK through the Society of Maritime Industries. Organisations that contributed to the development of the MASS Code of Practice include The Maritime & Coastguard Agency (MCA), Atlas Elektronik UK Ltd, AutoNaut, Fugro, the UK Chamber of Shipping, UKHO, Trinity House ...

Autonomous Spaceport Drone Ship
An autonomous spaceport drone ship (ASDS) is a modified ocean-going barge developed by SpaceX and equipped with propulsion systems to maintain precise position and a large floating landing platform, landing platform. They were developed to recover the First stage (rocketry), first stage (also called the booster) of its SpaceX launch vehicles, launch vehicles. By recovering and reusing these boosters, SpaceX has significantly reduced the cost of space launch. SpaceX operates three ASDS: ''Just Read the Instructions (II)'' (JRTI), ''A Shortfall of Gravitas'' (ASOG), and ''Of Course I Still Love You'' (OCISLY). JRTI and ASOG operate from Port Canaveral supporting launches from John F. Kennedy Space Center, Kennedy Space Center and Cape Canaveral Space Force Station landing in the Atlantic Ocean, while OCISLY operates from the Port of Long Beach supporting launches from Vandenberg Space Force Base landing in the Pacific Ocean. Depending on mission requirements, SpaceX can Return ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Target Drone
A target drone is an unmanned aerial vehicle, generally remote controlled, usually used in the training of anti-aircraft crews. One of the earliest drones was the British DH.82 Queen Bee, a variant of the Tiger Moth trainer aircraft operational from 1935. Its name led to the present term "drone". In their simplest form, target drones often resemble radio-controlled model aircraft. More modern drones may use countermeasures, radar, and similar systems to mimic manned aircraft. More advanced drones are made from large, older missiles which have had their warheads removed. In the United Kingdom, obsolete Royal Air Force and Royal Navy jet and propeller-powered aircraft (such as the Fairey Firefly, Gloster Meteor and de Havilland Sea Vixen used at RAE Llanbedr between the 1950s and 1990s) have also been modified into remote-controlled drones, but such modifications are costly. With a much larger budget, the U.S. military has been more likely to convert retired aircraft or ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Micro Air Vehicle
A micro air vehicle (MAV), or micro aerial vehicle, is a class of man-portable miniature UAVs whose size enables them to be used in low-altitude, close-in support operations. Modern MAVs can be as small as 5 centimeters - compare Nano Air Vehicle. Development is driven by commercial, research, government, and military organizations; with insect-sized aircraft reportedly expected in the future. The small craft allow remote observation of hazardous environments or of areas inaccessible to ground vehicles. Hobbyists have designed MAVs for applications such as aerial robotics contests and aerial photography. MAVs can offer autonomous modes of flight. Practical implementations In 2008, the TU Delft University in the Netherlands developed the smallest ornithopter fitted with a camera, the DelFly Micro, the third version of the DelFly project that started in 2005. This version measures 10 centimeters and weighs 3 grams, slightly larger (and noisier) than the dragonfly on whic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
