Unmanned Systems – Definition

An unmanned system, to me, is a system that operates entirely on its own or with the assistance of a human operating the system remotely. Unmanned systems can range from a tiny drone up to the size of a rocket. They are also available in different applications such as underwater, on land, in the air and even space. We are already surrounded by thousands of unmanned systems that get us through the day and sometimes without even knowing they are present.
