Uncrewed
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. 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) * Unmanned ground and aerial vehicle (UGAV), unmanned vehicle with hybrid locomotion methods * Unmanned aerial vehicle (UAV), unmanned aircraft commonly known as "drone" ** Unmanned combat aerial vehicle (UCAV) ** Medium-altitude long-endurance unmanned aerial vehicle (MALE) ** Miniature UAV (SUAV) ** Delivery drone ** Micro air vehicle (MAV) ** Target drone * Autonomous spaceport drone ship * Uncrewed surface ...

Uncrewed Spacecraft
Unmanned spacecraft or uncrewed spacecraft are spacecraft without people on board, used for robotic spaceflight. Uncrewed spacecraft may have varying levels of autonomy from human input; they may be remote controlled, remote guided or even autonomous, meaning they have a pre-programmed list of operations, which they will execute unless otherwise instructed. Many habitable spacecraft also have varying levels of robotic features. For example, the space stations Salyut 7 and Mir, and the International Space Station module Zarya, were capable of remote guided station-keeping and docking maneuvers with both resupply craft and new modules. The most common uncrewed spacecraft categories are robotic spacecraft, unmanned resupply spacecraft, space probed space observatories. Not every uncrewed spacecraft is a robotic spacecraft; for example, a reflector ball is a non-robotic uncrewed spacecraft.

Unmanned Aerial Vehicle
An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention. UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous" for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE T ...

Robotic Spacecraft
A robotic spacecraft is an uncrewed spacecraft, usually under telerobotic control. A robotic spacecraft designed to make scientific research measurements is often called a space probe. Many space missions are more suited to telerobotic rather than crewed operation, due to lower cost and lower 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 spacecraft technology, so telerobotic probes are the only way to explore them. Nearly all satellites, landers and rovers are robotic spacecraft. History The first robotic spacecraft was launched by the Soviet Union (USSR) on 22 July 1951, a suborbital flight carrying two dogs Dezik and Tsygan. Four other such flights were made through the fall of 1951. The first artificial satellite, Sputnik 1, was put into a Earth orbit by the ...

Unmanned Vehicles – The Increasing Challenge Of Autonomy1
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.

Uncrewed Surface Vehicle
Unmanned surface vehicles (USVs), also known as unmanned surface vessels, autonomous surface vehicles (ASVs) in some cases, uncrewed surface vessels (USVs), or colloquially drone ships, or robot boats, are boats or ships that operate on the surface of the water without a crew. USVs operate with various levels of autonomy, from remote control to fully autonomous. Some commercial USVs may utilize COLREGs-compliant navigation. USVs were used militarily as early as World War II for remote controlled target craft and minesweeper purposes, they are becoming more widely used in the twenty-first century for a range of purposes including oceanography and environmental monitoring, as well as cargo transport, and military applications. Various other applications are also being explored. In October 2022 during the Russian invasion of Ukraine Ukraine armed forces used 7 USVs and 8 UAVs in an attack on multiple Russian naval vessels at the Sevastopol Naval Base. According to Naval New ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optionally Piloted Vehicle
An optionally piloted vehicle (OPV) is a hybrid between a conventional piloted aircraft and an unmanned aerial vehicle (UAV). Able to fly with or without a human crew on board the aircraft, OPVs are a low-cost alternative to UAVs in research, experimentation, and concept exploration, but may also become used in mainstream operations as familiarity with them increases. Unimpeded by a human's physiological limitations, an OPV is able to operate under more adverse conditions and/or for greater endurance times. Retaining on-board controls, the OPV can operate as a conventional aircraft during missions for which direct human control is preferred or desired as an immediate option. The US Naval Postgraduate School Center for Interdisciplinary Remotely-Piloted Aircraft Studies (CIRPAS) in Monterey, California operates a highly modified Cessna 337-O2 Skymaster OPV called Pelican. The OPV provides a low-risk, low-cost test and evaluation alternative to a Predator UAV. The Pelican has als ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autonomous Spaceport Drone Ship
An autonomous spaceport drone ship (ASDS) is an ocean-going vessel derived from a deck barge, outfitted with station-keeping engines and a large landing platform and is autonomously controlled when on station for a landing. Construction of such ships was commissioned by aerospace company SpaceX to allow recovery of launch vehicle first stages at sea for missions that do not carry enough fuel to return to the launch site after boosting spacecraft onto an orbital or interplanetary trajectory. SpaceX has three operational drone ships: ''Just Read the Instructions (II)'' (JRTI) and ''A Shortfall of Gravitas'' (ASOG), operating in the Atlantic for launches from Kennedy Space Center and Cape Canaveral Space Force Station, and ''Of Course I Still Love You'' (OCISLY), operating in the Pacific for supporting missions from Vandenberg Space Force Base. JRTI operated in the Pacific Ocean for Vandenberg Air Force Base launches from 2016 to 2019 before leaving the Port of Los Angeles ...

Vehicular Automation
Vehicular automation involves the use of mechatronics, artificial intelligence, and multi-agent systems to assist the operator of a vehicle (car, aircraft, watercraft, or otherwise).Hu, J.; Bhowmick, P.; Lanzon, A.,Group Coordinated Control of Networked Mobile Robots with Applications to Object Transportation IEEE Transactions on Vehicular Technology, 2021.Hu, J.; Bhowmick, P.; Jang, I.; Arvin, F.; Lanzon, A.,A Decentralized Cluster Formation Containment Framework for Multirobot Systems IEEE Transactions on Robotics, 2021. These features and the vehicles employing them may be labeled as ''intelligent'' or ''smart''. A vehicle using automation for difficult tasks, especially navigation, to ease but not entirely replace human input, may be referred to as ''semi-autonomous'', whereas a vehicle relying solely on automation is called robotic or autonomous. Both of these types are instantiated in today's various self-driving cars, unmanned surface vehicles, autonomous trains, ad ...

Space Probe
A space probe is an artificial satellite that travels through space to collect scientific data. A space probe may orbit Earth; approach the Moon; travel through interplanetary space; flyby, orbit, or land or fly on other planetary bodies; or enter interstellar space. Many countries and private companies have launched probes to planets, asteroids, moons around the Solar System, including the Soviet Union, the United States, India, and many more. History On 4 October 1957, the first artificial satellite to orbit Earth was Sputnik 1, launched by the USSR. Four months later, on 1 February 1958, Explorer 1 was launched by the United States, being the first space probe. Explorer 1, collecting data on temperature, cosmic rays, and micrometeorite impacts. The first attempted lunar probe was the Luna E-1 No.1, launched on 23 September 1958. The goal of a lunar probe repeatedly failed until 4 January 1959 when Luna 1 orbited around the moon and then the sun. The success of t ...

Underwater Glider
An underwater glider is a type of autonomous underwater vehicle (AUV) that employs variable-buoyancy propulsion instead of traditional propellers or 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 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-like profile followed by a glider can provide data on temporal and spatial scales unattainable by powered AUVs and much more costly to sample using traditional shipboard techniques.
