Drones: A new way to look at the world..

DRONES

Human beings always had a queer interest in observing the world from different directions, angles and views,Aerial, underwater(marine),heights of mountains etc.

Drones give perfect hand fullness in observation of earth from up in sky. 

In technical way, An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot aboard. The flight of UAVs may be controlled with various kinds of autonomy : either by a given degree of remote control from an operator, located on the ground or in another vehicle, or fully autonomously, by onboard computers.

In 1849 Austria sent unmanned, bomb-filled balloons to attack Venice. Drone innovations started in the early 1900s and originally focussed on providing practice targets for training military personnel. UAV development continued during World War I, when the Dayton-Wright Airplane Company invented a pilotless aerial torpedo that would drop and explode at a preset time.The earliest attempt at a powered unmanned aerial vehicle was A. M. Low's "Aerial Target" of 1916.Nikola Tesla described a fleet of unmanned aerial combat vehicles in 1915. A number of remote-controlled-airplane advances followed during and after World War I, including the Hewitt-Sperry Automatic Airplane.

APPLICATION FOCUS:

Manned and large unmanned aircraft of the same type generally have recognizably similar physical components, the main exceptions being the cockpit and environmental control system or life support systems. Some UAVs carry payloads (such as a camera) which weigh considerably less than an adult human, and as a result can be considerably smaller. Though they carry heavy payloads, weaponized military drones are also lighter than their manned counterparts with comparable armaments.

   

SOFTWARE:

The UAV computer software are layered in tiers with different time requirements. The combination of layers is sometimes called the flight stack, or autopilot.Onboard classical operating systems alone are not ideal for flying UAVs: high response times may be fatal to the aircraft. Thus they may be completed by externally supported middlewares: RaspberryPis, Beagleboards, etc. shielded with NavIO, PXFMini, etc. or designed from scratch for hard real-time requirements, like Nuttx, preemp-RT Linux, Xenomai, Orocos-Robot Operating System, DDS-ROS 2.0 for instance.
