Radio-controlled
Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remote control, remotely control a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors. Radio control is also used for control of Radio-controlled model, model vehicles from a hand-held radio transmitter. Industrial organization, Industrial, Military organization, military, and scientific research organizations make use of radio-controlled vehicles as well. A rapidly growing application is control of unmanned aerial vehicles (UAVs or drones) for both civilian and military uses, although these have more sophisticated control systems than traditional applications. History The idea of controlling unmanned vehicles (for the most part in an attempt to improve the accuracy of torpedoes for military purposes) predates the invention of radio. The latter half of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radio-controlled Model
A radio-controlled model (or RC model) is a Physical model, model that is steering, steerable with the use of radio control. All types of model vehicles have had RC systems installed in them, including radio-controlled car, ground vehicles, radio-controlled boat, boats, radio-controlled airplane, planes, Radio-controlled helicopter, helicopters and even radio-controlled submarine, submarines and scale railway locomotives. History Radio control has been around since Nikola Tesla demonstrated a remote control boat in 1898. World War II saw increased development in radio control technology. The Luftwaffe used controllable winged bombs for targeting Allies of World War II, Allied ships. During the 1930s the Good brothers Bill and Walt pioneered vacuum tube based control units for R/C hobby use. Their "Guff" radio controlled plane is on display at the National Aerospace museum. Ed Lorenze published a design in Model Airplane News that was built by many hobbyists. Later, after WW2, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 Tr ...

British Unmanned Aerial Vehicles Of World War I
Soon after its re-purposing from the Army Balloon Factory to the Royal Aircraft Factory in 1912, designers at this Farnborough base turned their thoughts to flying an unmanned aircraft. During the First World War this pioneering work resulted in trials of remotely controlled aircraft for the Royal Flying Corps and unmanned boats for the Royal Navy that were controlled from 'mother' aircraft. By the end of the war in 1918 Britain had successfully flown and controlled a drone aircraft and a number of fast unmanned motor boats operating in close flotilla formation had been individually controlled by radio from operators flying in "mother" aircraft. This work then continued in the inter war years. The Factory's 1914 design There is a Royal Aircraft Factory engineering drawing dated October 1914 of an unmanned powered monoplane long with a wingspan. This was developed as a possible defence to counter the threat of aerial bombing from German dirigible airships. This new potential wea ...

Radio
Radio is the technology of signaling and communicating using radio waves. Radio waves are electromagnetic waves of frequency between 30 hertz (Hz) and 300 gigahertz (GHz). They are generated by an electronic device called a transmitter connected to an antenna which radiates the waves, and received by another antenna connected to a radio receiver. Radio is very widely used in modern technology, in radio communication, radar, radio navigation, remote control, remote sensing, and other applications. In radio communication, used in radio and television broadcasting, cell phones, two-way radios, wireless networking, and satellite communication, among numerous other uses, radio waves are used to carry information across space from a transmitter to a receiver, by modulating the radio signal (impressing an information signal on the radio wave by varying some aspect of the wave) in the transmitter. In radar, used to locate and track objects like aircraft, ships, spacecraf ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Remote Control
In electronics, a remote control (also known as a remote or clicker) is an electronic device used to operate another device from a distance, usually wirelessly. In consumer electronics, a remote control can be used to operate devices such as a television set, DVD player or other home appliance. A remote control can allow operation of devices that are out of convenient reach for direct operation of controls. They function best when used from a short distance. This is primarily a convenience feature for the user. In some cases, remote controls allow a person to operate a device that they otherwise would not be able to reach, as when a garage door opener is triggered from outside. Early television remote controls (1956–1977) used ultrasonic tones. Present-day remote controls are commonly consumer infrared devices which send digitally-coded pulses of infrared radiation. They control functions such as power, volume, channels, playback, track change, heat, fan speed, and vario ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
MQ-1 Predator Unmanned Aircraft
The General Atomics MQ-1 Predator (often referred to as the predator drone) is an American remotely piloted aircraft (RPA) built by General Atomics that was used primarily by the United States Air Force (USAF) and Central Intelligence Agency (CIA). Conceived in the early 1990s for aerial reconnaissance and forward observation roles, the Predator carries cameras and other sensors. It was modified and upgraded to carry and fire two AGM-114 Hellfire missiles or other munitions. The aircraft entered service in 1995, and saw combat in the War in Afghanistan (2001–present), war in Afghanistan, War in North-West Pakistan, Pakistan, the NATO intervention in Bosnia, 1999 NATO bombing of Yugoslavia, the Iraq War, Yemen, the 2011 Libyan civil war, the 2014 US-Coalition intervention in Syria, 2014 intervention in Syria, and Somalia. The USAF describes the Predator as a "Tier II" MALE UAS (medium-altitude, long-endurance unmanned aircraft system). The UAS consists of four aircraft or "air ...

Leonardo Torres Y Quevedo
Leonardo Torres y Quevedo (; 28 December 1852 – 18 December 1936) was a Spanish civil engineer and mathematician of the late nineteenth and early twentieth centuries. Torres was a pioneer in the development of the radio control and automated calculation machines, the inventor of a chess automaton, and a innovative designer of the three-lobed non-rigid Astra-Torres airship and the Whirlpool Aero Car located in Niagara Falls. With his ''Telekine'', Torres-Quevedo created wireless remote-control operation principles. He was also a famous speaker of Esperanto. Biography Torres was born on 28 December 1852, on the Feast of the Holy Innocents, in Santa Cruz de Iguña, Cantabria, Spain. The family resided for the most part in Bilbao, where Leonardo's father worked as a railway engineer, although they also spent long periods in his mother's family home in the Cantabria's mountain region. In Bilbao he studied to enter an advanced high school program, and later spent two years in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Paris Academy Of Science
The French Academy of Sciences (French: ''Académie des sciences'') is a learned society, founded in 1666 by Louis XIV at the suggestion of Jean-Baptiste Colbert, to encourage and protect the spirit of French scientific research. It was at the forefront of scientific developments in Europe in the 17th and 18th centuries, and is one of the earliest Academies of Sciences. Currently headed by Patrick Flandrin (President of the Academy), it is one of the five Academies of the Institut de France. History The Academy of Sciences traces its origin to Colbert's plan to create a general academy. He chose a small group of scholars who met on 22 December 1666 in the King's library, near the present-day Bibliothèque Nationals, and thereafter held twice-weekly working meetings there in the two rooms assigned to the group. The first 30 years of the Academy's existence were relatively informal, since no statutes had as yet been laid down for the institution. In contrast to its ...

Astra-Torres Airship
The Astra-Torres airships were non-rigid airships built by Société Astra in France between about 1908 and 1922 to a design by the Spaniard Leonardo Torres Quevedo. They had a highly-characteristic tri-lobed cross-section rather than the more usual circular cross-section. This was the result of moving most of the blimp's bracing wires inside the envelope in an attempt to minimise drag. Early Astra-Torres airships could be trimmed by moving the entire gondola fore-and-aft. Astra-Torres airships were used by the French Navy during the First World War and for a few years before and after. A few of these were transferred to the American expeditionary forces in Europe, and AT-1, AT-13 and AT-17 were eventually taken back to the United States. Britain's Royal Naval Air Service purchased AT-14, AT-17 and AT-19, these becoming HMA No. 3, HMA No. 8 and HMA No. 16 respectively. They went through testing and evaluation at RNAS Kingsnorth before all were later taken out of service in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Port Of Bilbao
The Port of Bilbao is located on the Bilbao Abra bay, and along the Estuary of Bilbao, in Biscay ( Basque Country). The main facilities are in the Santurtzi and Zierbena municipalities, approximately 15 km (9.3 mi) west of Bilbao. Also called ''Exterior Port'' and ''Superpuerto'', the port complex occupies 3.13 km² (773 acres) of land and 16.94 km² (4,186 acres) of water along 17 km (10.6 mi) of waterfront. History The history of the port is inseparably linked to the history of Bilbao itself, so the date of its foundation is also that of the city's foundation. In 1300 Bilbao was granted the status of city and was given control of the maritime traffic entering its estuary. The first docks were built at Bilbao's old town, 15 km (9.3 mi) upstream from the open sea. These docks were the center of the port's activity for more than five centuries. In 1511 the ''Consulate of Bilbao'' privilege was granted, which allowed the port control over th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Archibald Low
Archibald Montgomery Low (17 October 1888 – 13 September 1956) developed the first powered drone aircraft. He was an English consulting engineer, research physicist and inventor, and author of more than 40 books. Low has been called the "father of radio guidance systems" due to his pioneering work on planes, torpedoes boats and guided rockets. He was a pioneer in many fields though, often leading the way for others, but his lack of discipline meant he hardly ever saw a project through, being easily distracted by new ideas. If it wasn't for this inability to see things to a conclusion, Low could well have been remembered as one of the great men of science. Many of his scientific contemporaries disliked him, due in part to his using the title "professor", which he wasn't entitled to do as he didn't occupy an academic chair. His love of the limelight and publicity probably also added to the dislike. Low was working on the invention of television before World War I Bloom, Ur ...
