At the beginning of its history, drones are unmanned aircraft that is used as a simple target shooting. During its development, the drone is made more complex and has various features so that the drones are currently used for the benefit of the wider with advanced technology. Used to spy or attack military, territorial monitoring, search and rescue, or just a hobby. In science fiction movies, drones depicted in a more sophisticated version of the imagination with all the technological capabilities of the future.
Now, drones are unmanned aircraft that has many usability features. Operational drones are controlled remotely. Now the function of ‘drones’ are increasingly being used in various purposes not only for military operations. Aircraft ‘drone’ now began to be developed for the purpose in the health field, such as for the transport of medicines and medical equipment, primarily to penetrate areas of conflict or disaster.
Drones are also widely used for agriculture, such as for the evaluation of the condition of the soil or map out the direction of the tractor, or also to spread pesticides, water and fertilizer. Drone also used to help weather reports, storm detect, predict and study the weather. Other functions, the types of drones you can buy online are used for three-dimensional mapping, surveying the surface of the ground and then made in the form of maps.
Drone also has begun to be used for search and rescue operations, especially at night in a large area and difficult area Also used to monitor wildlife, monitor the population and animal life as well as assisting in forest conservation activities.
Drone also began to be developed for the purposes of journalism, for example to bring photos, take pictures, record video and data collection. Also began to be used for sending goods and food.
Here I add the explanation that I quoted from the site Wikipedia.org. According to Wikipedia, drone aircraft, is an aircraft without a pilot. This plane does not require a pilot to guide the aircraft. This plane is often called UAV or Unmanned Aerial Vehicle. UAV is a flying machine that is controlled remotely by the pilot or unable to control him. Just like other aircraft, drones also use the laws of aerodynamics to lift him.
Now drone is widely used for the purposes of military operations. In operations in Afghanistan, for example the United States, using drone aircraft to bombard the Taliban’s defense and hideouts. Like the fighter aircraft, drones are also able to carry a gun or a bomb. Drone also works as fighter aircraft, firing missiles and dropping bombs.
