A Drone is an unmanned aircraft. Drones, also called unmanned aerial vehicles (UAVs), have no human pilot onboard, and instead are either controlled by a person on the ground or autonomously via a computer program. The drone can be completely Autonomous with the help of onboard software and FCB. Drones can be remotely controlled (RC) by Bi-directional radio waves. Most Drones work in conjunction with onboard sensors and GPS. The drone can have a fixed wing, rotary wing or hybrid design. Most drones have various kinds of Autonomy related features like Headless mode, Follow me, One key return etc. Drones can have fuel engines (Gas, turbine, Wankel) and batteries as power supply. Drones can be as big as 61m in wing span and can be as small as less than 1mm. Some drones are waterproof especially Underwater marine drones. 

Military drones can carry up to 3000kg payloads and fly as high as 60000 feet.  Abraham Karem is regarded as the founding future of (UAV) Drones. He made drones in 1951. He had an innate passion for aeronautics, and at the age of 14, he started building model aircraft. Karem is regarded as the founding father of UAV (drone) technology. He graduated in aeronautical engineering from The Technion. He built his first drone during the Yom Kippur war for Israeli Air Force. 

Drones have two basic functions: Fight mode and Navigation. These stealth crafts are becoming increasingly popular, not just for war and military purposes, but also for everything from wildlife and atmospheric research to disaster relief and sports photography. Drones are becoming the eyes and ears of scientists by surveying the ground for archaeological sites, signs of illegal hunting and crop damage, and even zipping inside hurricanes to study the wild storms. 

An agricultural drone is an unmanned aerial vehicle used in agriculture operations mostly in field optimization and monitoring crop growth and crop production. Agricultural drones provide information on crop growth stages, crop health and soil variation. You can even rent a personal drone to soar above the horizon and snap a photo or video.

Drones Find Unexpected Radiation 'Hotspots' in Forest Near Chornobyl. Near ground zero of the catastrophic 1986 explosion at the Chornobyl Nuclear Power Plant, aerial drones recently revealed radioactive hotspots that aren't on official maps.

An interdisciplinary team flew special drones over Ukraine's Red Forest, one of the most radioactive spots in the world, which is located 0.3 miles (500 meters) from the Chornobyl complex, University of Bristol (UB) representatives announced in a statement.

Pseudo-Satellite Drone Flies for 25 Days Straight, Sets Endurance Record, A solar-powered drone designed to take on the multimillion-dollar market for satellites in space has set a record by staying in flight at high altitude for nearly 26 days. Airbus has plenty of plans for its so-called pseudo-satellite, including possible military reconnaissance and monitoring the spread of wildfires, among other activities.

The European aerospace consortium Airbus announced that the latest model of its Zephyr drone had landed near Yuma, Arizona, late last week, after staying on the wing continuously for 25 days, 23 hours and 57 minutes, and breaking a world record for long-endurance flight. The drone was driven by electric power from solar panels on its wings during daylight when it flew at altitudes above 70,000 feet (21,300 meters), Airbus spokesman Alain Dupiech told Live Science.

No doubt, the exponential growth of the drone industry will continue to revolutionize our future decades. Surely you don’t want to miss the chance of enjoining yourself with this evolving UAV field whether by being a drone pilot or who knows maybe by being a drone developer even.

How drones are waging a stealth war on the way we think about society

MACHINES are only as good as the people who use them. They are neutral – just a faster, more efficient way of doing something that we always intended to do. That is the argument wielded by defenders of technology, anyway.
