A quadruplet is a multiplier that is lifted by four rotors. Unlike traditional helicopters, the quadruplet use 2 sets of propellers with 2 clockwise and 2 anti- clockwise. It was first designed by Louis Brute in 1907. It lifted off the ground by using four propellers In four different directions. Although It could only go up for several feet, it was a great step for the development of quadruplets. More than a decade later, in the asses, more engineers and scientists developed their own types f oratorical.Edmond Machine, a French engineer and helicopter designer, successfully designed a multiplier with four rotors that were installed at the ends of four arms. It provided a very high stability at that time and marked a record of 360 meters traveling distance. As time has passed, the quadruplet has changed into different styles and models. In asses-1 sass, the world was undergoing a very rapid economic development. There was a huge demand for transportation of Industrial materials. The quadruplet was a machine that people always prefer to use.However, due to lack improvement of the quadruplet, it was still not adopted for industrial use. In recent years, many small scale quadruplet are widely used in many ways. As there are many advanced airplanes, quadruplets are no longer under consideration as a means to transport people or commodities. Instead, they are used in different areas, like ordnance surveying, rescue support, film taking etc. Nowadays, quadruplets are always equipped with a camera. The data recorded by a quadruplet can be directly sent to a computer or saved in a storage system.During the Chuan earthquake In 2008, landslides blocked miles of country roads and properties. The rescuers could not enter the affected area. Also, airplanes could land or fly over some of these remote areas. The situation in the affected area remained unknown for the rescuers. The quadruplet help people to assess the damage quickly and more accurately in the remote areas. The ID robotics quadruplet, supported by a simple GAPS controlled through a computer, allowed the rescue teams to locate the affected areas.As the quadruplet is small in size and invulnerable, it can travel to very inaccessible places. We no longer need to rely on expensive alternatives like helicopters. Another common application of the quadruplet Is video and film taking. In the old days, if we want to take some scenes in the sky, we would probably need to use an airplane to help us. However, it is very difficult for an airplane to fly between skyscrapers and along narrow streets like In Hong Kong. Yet, but using a quadruplet can help the directors to achieve this goal.Since the quadruplet can be controlled by remote control or through computer programs, people can control their quadruplet to any direction they like. No matter whether you are standing on a cliff, or in I OFF flexibility and effectiveness of film making. The above applications are not those which are common in most pe ople's lives. Many people cannot afford to buy a quadruplet. Even if they could afford one, there are few ways that they could use it. However, in the future, we will have a chance to see hundreds of quadruplets flying over our heads.The world largest online retailer Amazon introduced a new delivery system-?Prime Air. This futuristic system allows customers to get their ordered packages into their hands within half an hour via unmanned aerial vehicles. The specially designed aerial vehicle is based on a prototype of a quadruplet. There are clamps to hold a box under the copter. The aerial vehicle is equipped with and tracked by a very precise GAPS system. It can even direct the copter outside the shopper's doorstep. In the future, the world's population will keep increasing. Land will become more crowded.Other than open up underground areas, the air space is expected to open p when we have better technology capabilities. As online shopping is growing in popularity, the Prime Air not only can boost the efficiency and economic growth, it can greatly reduce the demand for land transportation. To make Prime Air practicable, many weaknesses need to be considered and solved. What people discuss the most is safety. People will probably feel frightened and worried when they see a flying machine whizzing Just ten meters above their heads. People will also wonder whether the clamps strong enough to hold the box without dropping it.Although the copter is tracked by a very accurate GAPS system, there are many physical obstacles like trees, streetlights, advertisements and even construction sites which are not shown or frequently updated in the system. The technologies nowadays may not be capable to direct the unmanned aerial vehicles to keep away from these obstacles. This puts a restriction on sending a copter to crowded and busy areas like Hong Kong or New York. In the meantime, engineers needs to consider other problems like weather, battery life, load capacity and sec urity.A quadruplet for goods delivery use needs some kind f design to protect the electronic components inside it and this type of service would be highly susceptible to the weather conditions. If the quadruplet could only operate on dry days, the whole concept may somewhat lose it's meaning of effective delivery. What's more, there is no one guard the copter. How can we ensure it can safely and accurately fly to the destination? There are still many things need to deal with in the future to make an application like this a reality. In the future, accoutered will be more commonly used in different aspects.
