The aircraft carrier "Royal Ark" built by Britain in the 1960s and 1930s adopted a fully enclosed hangar, an integrated island superstructure, a powerful flight deck and a hydraulic catapult, and was hailed as "the embryonic form of a modern aircraft carrier". The Washington Naval Treaty expired in 1936, and the naval powers launched a new round of arms race. The York-class aircraft carrier in the United States, the Xianghe-class aircraft carrier in Japan and the Glorious-class aircraft carrier in Britain are all representative works of this period. Aircraft carriers were widely used for the first time in World War II. It is a small floating air station, carrying fighters and bombers away from the country to carry out the task of attacking enemy targets. This enables aircraft carriers to attack land and sea targets from the air, especially those far beyond the general range. The operational radius of the aircraft taking off from the aircraft carrier has been changing the naval operational theory constantly, and the opposing fleets must conduct long-distance operations with each other without seeing the other ships. This completely ended the dominance of the battleship as the strongest warship at sea. 1940,165438+1October, 1 1, the aircraft carrier was built for the first time in the war. The aircraft carrier Gloria of the British Navy attacked the Italian navy with torpedo bombers in taranto Harbor, sinking and injuring three battleships. This move made the United States and other maritime powers aware of the arrival of the aircraft carrier era. In World War II, the aircraft carrier played a decisive role in the battlefield of the Pacific War. From the Japanese naval aircraft carrier's sneak attack on Pearl Harbor, to the Coral Sea naval battle where the two fleets never met, and then to the Midway Island naval battle, the aircraft carrier formed a decisive battle at sea. Since then, aircraft carriers have replaced battleships as the backbone of modern ocean-going fleets. The United States has built a large number of Essex-class aircraft carriers, forming a huge aircraft carrier formation and becoming the protagonist of naval battles. During the war, a large number of cheap small escort carriers were built and put into anti-submarine escort operations. At the beginning of 2008, a new type of ship weapon handling robot developed by Foster Miller Company took shape. Soon, people will see robots carrying missiles and torpedoes on aircraft carriers, deck-crossing amphibious ships and other carrier-based aircraft, as if they were in the world of science fiction. This new shipborne weapon processing system is funded by the US Naval Air Systems Command and is one of the supporting equipment for the CVN 2 1 class aircraft carrier project. The project contract was signed on September 8, 2004, with a total value of US$ 2.5 million and a period of five years. In the next few years, * * * will produce hundreds of sets of this system, which not only can meet the needs of the US Navy, but also has the value of promoting the use of material handling and medical assistance in the commercial field. Foster Miller Company of the United States is the main robot supplier of the US military. Today, most robots in Iraq and Afghanistan are products of this company. On June 7th, 2004, at 65438, Foster Miller launched the EOD robot of laser blasting, which was equipped with machine guns, sniper rifles, grenades, rocket launchers and other weapons. Prior to this, the laser blasting produced by Miller Company had experienced many battles. In the wars in Kosovo, Afghanistan and Iraq, the US military successfully completed the reconnaissance and demining tasks for the enemy. There is also the famous "Talon" robot, and the contract amount has also increased from the initial $27.5 million to the current $65.438+$24 million. In the process of developing the ship maneuvering robot, the researchers found that the existing commercial motors and transmission devices could not meet the expected design requirements. For example, only high-pressure hydraulic technology can provide enough torque, but the disadvantages are obvious: it is not only easy to leak oil, but also has long failure time and high maintenance requirements. Because once the hydraulic oil leaks and pollutes the runway of the carrier-based aircraft or simply "strikes" during handling, it will be fatal. So the company innovated the structure of the motor and developed a system with torque 50 times that of the existing motor. Finally, a new type of ship-borne weapon handling robot is designed and formed, which adopts all-electric drive and transmission system, excluding the hydraulic system that may leak oil, thus prolonging the service life and reducing the cost. The system mainly consists of a handling robot, an automatic workpiece identification system, an automatic starting device and an automatic transmission device. Different grippers can be equipped according to different tasks, such as mechanical grippers, vacuum suckers, electromagnetic suckers, etc., which can realize the grabbing and handling of different weapons and ammunition. It has the characteristics of accurate positioning and identification, stable and reliable operation and sufficient control force. For example, the US Army used a hexapod robot called Octopus in transporting ammunition and various dangerous operations, which can carry 409 kilograms of ammunition when walking.
