ABSTRACT
Historically, a variant of drone technology that utilizes a trained Golden Eagle to hunt animals for food was practiced by several tribes in Central Asia and Russian Steppes. It is called Falconry. Their basic techniques and purpose match with several aspects of present day agricultural drones. Trained eagles scout, survey and hunt animals such as wolves, rodents, ovine and fowl. The degree to which drones are autonomous is a useful criterion to classify them. First group known as Semi-Autonomous Drones are provided with instructions by operators. Critical decisions such as flight path, photographing land and its topology, natural resources at a particular point, or making a video-graphic observation of an event on land surface are decided using remote control. Based on controllers, agricultural drones could be grouped into those guided using a semi-autonomous flight controller or those by fully autonomous flight controllers. The semi-autonomous flight controller requires a human skilled operator to manually supply inputs.
