Unmanned Ground Vehicles
An unmanned ground vehicle (UGV) also known colloquially as armored robot (ARB) is a vehicle that operates while in contact with the ground without an onboard human presence. UGVs can be used for many applications where it is inconvenient, dangerous, expensive, or impossible to use an onboard human operator. Typically, the vehicle has sensors to observe the environment, and autonomously controls its behavior or uses a remote human operator to control the vehicle via teleoperation. The UGV is the land-based counterpart to unmanned aerial vehicles, unmanned underwater vehicles and unmanned surface vehicles. Unmanned robotics are being actively developed for both civilian and military use. History In 1904, Spanish engineer Leonardo Torres Quevedo was developing a radio-based control system he named Leonardo Torres Quevedo#Radio control: the Telekino, ''Telekino''. He chose to conduct an initial test in the form of a three-wheeled land vehicle (tricycle), which had an effectiv ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gladiator 240G
A gladiator ( , ) was an armed combatant who entertained audiences in the Roman Republic and Roman Empire in violent confrontations with other gladiators, wild animals, and condemned criminals. Some gladiators were volunteers who risked their lives and their legal and social standing by appearing in the arena. Most were despised as slaves, schooled under harsh conditions, socially marginalized, and segregated even in death. Irrespective of their origin, gladiators offered spectators an example of Rome's martial ethics and, in fighting or dying well, they could inspire admiration and popular acclaim. They were celebrated in high and low art, and their value as entertainers was commemorated in precious and commonplace objects throughout the Roman world. The origin of gladiatorial combat is open to debate. There is evidence of it in funeral rites during the Punic Wars of the 3rd century BC, and thereafter it rapidly became an essential feature of politics and social life in the ...

Strategic Computing Initiative
The United States government's Strategic Computing Initiative funded research into advanced computer hardware and artificial intelligence from 1983 to 1993. The initiative was designed to support various projects that were required to develop machine intelligence in a prescribed ten-year time frame, from chip design and manufacture, computer architecture to artificial intelligence software. The Department of Defense spent a total of $1 billion on the project. The inspiration for the program was Japan's fifth generation computer project, an enormous initiative that set aside billions for research into computing and artificial intelligence. As with Sputnik in 1957, the American government saw the Japanese project as a challenge to its technological dominance. The British government also funded a program of their own around the same time, known as Alvey, and a consortium of U.S. companies funded another similar project, the Microelectronics and Computer Technology Corporation.

DARPA
The Defense Advanced Research Projects Agency (DARPA) is a research and development agency of the United States Department of Defense responsible for the development of emerging technologies for use by the military. Originally known as the Advanced Research Projects Agency (ARPA), the agency was created on February 7, 1958, by President Dwight D. Eisenhower in response to the Soviet Union, Soviet launching of Sputnik 1 in 1957. By collaborating with academia, industry, and government partners, DARPA formulates and executes research and development projects to expand the frontiers of technology and science, often beyond immediate U.S. military requirements.Dwight D. Eisenhower and Science & Technology, (2008). Dwight D. Eisenhower Memorial CommissionSource The name of the organization first changed from its founding name, ARPA, to DARPA, in March 1972, changing back to ARPA in February 1993, then reverted to DARPA in March 1996.

Shakey The Robot
Shakey the Robot was the first general-purpose mobile robot able to reason about its own actions. While other robots would have to be instructed on each individual step of completing a larger task, Shakey could analyze commands and break them down into basic chunks by itself. Due to its nature, the project combined research in robotics, computer vision, and natural language processing. Because of this, it was the first project that melded logical reasoning and physical action. Shakey was developed at the Artificial Intelligence Center of Stanford Research Institute (now called SRI International). Some of the most notable results of the project include the A* search algorithm, the Hough transform, and the visibility graph method. History Shakey was developed from approximately 1966 through 1972 with Charles Rosen, Nils Nilsson and Peter Hart as project managers. Other major contributors included Alfred Brain, Sven Wahlstrom, Bertram Raphael, Richard Duda, Richard Fikes, T ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Battle Of France
The Battle of France (; 10 May – 25 June 1940), also known as the Western Campaign (), the French Campaign (, ) and the Fall of France, during the Second World War was the Nazi Germany, German invasion of the Low Countries (Belgium, Luxembourg and the Netherlands) and French Third Republic, France. The plan for the invasion of the Low Countries and France was called (Case Yellow or the Manstein plan). (Case Red) was planned to finish off the French and British after the Dunkirk evacuation, evacuation at Dunkirk. The Low Countries and France were defeated and occupied by Axis troops down to the Demarcation line (France), Demarcation line. On 3 September 1939, French declaration of war on Germany (1939), France and United Kingdom declaration of war on Germany (1939), Britain declared war on Nazi Germany, over the German invasion of Poland on 1 September.

Goliath Tracked Mine
The Goliath tracked mine (German: ''Leichter Ladungsträger Goliath'', "Goliath Light Charge Carrier") was a series of two unmanned ground vehicles used by the German Army as disposable demolition vehicles during World War II. These were the electrically powered ''Sd.Kfz. 302'' and the petrol-engine powered ''Sd.Kfz. 303a'' and ''303b''. They were known as "beetle tanks" by the Allies. They carried of high explosives, depending on the model, and were intended to be used for multiple purposes, such as destroying tanks, disrupting dense infantry formations, and the demolition of buildings or bridges. Goliaths were single-use vehicles that were destroyed by the detonation of their warhead. Development During and after World War I, a number of inventors devised small, remote-controlled, tracked vehicles intended to carry an explosive charge. During the war, the French developed two vehicles. The ''Crocodile Schneider Torpille Terrestre'' () carried a explosive charge and saw limi ...

Wehrmacht
The ''Wehrmacht'' (, ) were the unified armed forces of Nazi Germany from 1935 to 1945. It consisted of the German Army (1935–1945), ''Heer'' (army), the ''Kriegsmarine'' (navy) and the ''Luftwaffe'' (air force). The designation "''Wehrmacht''" replaced the previously used term (''Reich Defence'') and was the manifestation of the Nazi regime's efforts to German rearmament, rearm Germany to a greater extent than the Treaty of Versailles permitted. After the Adolf Hitler's rise to power, Nazi rise to power in 1933, one of Adolf Hitler's most overt and bellicose moves was to establish the ''Wehrmacht'', a modern offensively-capable armed force, fulfilling the Nazi regime's long-term goals of regaining lost territory as well as gaining new territory and dominating its neighbours. This required the reinstatement of conscription and massive investment and Military budget, defence spending on the arms industry. The ''Wehrmacht'' formed the heart of Germany's politico-military po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Preselector Gearbox
A preselector gearbox is a type of manual transmission mostly used on passenger cars and racing cars in the 1930s, in buses from 1940–1960 and in armoured vehicles from the 1930s to the 1970s. The defining characteristic of a preselector gearbox is that the gear shift lever allowed the driver to "pre-select" the next gear, usually with the transmission remaining in the current gear until the driver pressed the "gear change pedal" at the desired time. The design removed the need for the driver to master the timing of using a clutch pedal and shift lever in order to achieve a smooth shift in a non-synchromesh manual transmission. Most pre-selector transmissions avoid a driver-controlled clutch entirely. Some use one solely for starting from a standstill. Preselector gearboxes were most common prior to the widespread adoption of the automatic transmission, so they were considered in comparison to the " crash gearbox" type of manual transmission. Preselector gearboxes were often m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Matilda II
The Infantry Tank Mark II, better known as the Matilda, is a British infantry tank of the Second World War.Jentz, p. 11. The design began as the A12 specification in 1936, as a gun-armed counterpart to the first British infantry tank, the machine gun armed, two-man A11 Infantry Tank Mark I. The Mark I was also known as Matilda, and the larger A12 was initially known as the Matilda II or Matilda senior. The Mark I was abandoned in 1940, and from then on the A12 was almost always known simply as "the Matilda". With its heavy armour, the Matilda II was an excellent infantry support tank but with somewhat limited speed and armament. It was the only British tank to serve from the start of the war to its end, although it is particularly associated with the North Africa Campaign. Only two were available for service by the outbreak of World War II in 1939. It was replaced in front-line service by the cheaper and lighter Infantry Tank Mk III Valentine from late 1941.

Operation Barbarossa
Operation Barbarossa was the invasion of the Soviet Union by Nazi Germany and several of its European Axis allies starting on Sunday, 22 June 1941, during World War II. More than 3.8 million Axis troops invaded the western Soviet Union along a front, with the main goal of capturing territory up to a line between Arkhangelsk and Astrakhan, known as the A-A line. The attack became the largest and costliest military offensive in history, with around 10 million combatants taking part in the opening phase and over 8 million casualties by the end of the operation on 5 December 1941. It marked a major escalation of World War II, opened the Eastern Front—the largest and deadliest land war in history—and brought the Soviet Union into the Allied powers. The operation, code-named after the Holy Roman Emperor Frederick Barbarossa ("red beard"), put into action Nazi Germany's ideological goals of eradicating communism and conquering the western Soviet Union to repopulate it w ...
