How Drones are being used to make the world a better place

A Drone is capable of controlled, sustained level flight and is powered by a jet, reciprocating, or electric engine. Drone Technology is commonly used by the military, but are also being implemented in search and rescue operations and being utilized in other civil applications, such as policing and firefighting. Drone’s also known as unmanned aerial vehicles (UAV), are pilot less and non-crewed aircraft that are capable of flight either by remote control or through the use of on-board computers.

Some of the ways drones are making a difference for the better.

  1. Wildlife protection

  2. Humanitarian response

  3. Peacekeeping

  4. Cargo deliveries

  5. Crisis mapping

The use of drones has grown quickly in recent years because unlike manned aircraft they can stay aloft for many hours they are much cheaper than military aircraft and they are flown remotely so there is no danger to the flight crew. Only with major improvements in computing and electronic controlling systems in the 1980 s and ’90 s were modern-day drones made possible. And it wasn’t until the late ’90 s that the Air Force began working on the technical aspects of arming unmanned aircraft with missiles.

Variations of Drone Technology

  1. Main Controller – The heart of the flight-control system, this can be thought of as the “brains” of the UAV.

  2. Gyros/Sensors – For autonomy to work, the MC needs to track how the aircraft is flying. To accomplish this, some form of sensor array is provided.

  3. Electronic Speed Controllers – Each motor has an ESC. In its most basic form, an ESC regulates power going to the motor with which it is paired.

  4. Receiver – This receiver is for the radio control system. It pairs with the controller the pilot or operator holds, which logically, if confusingly, is known as the “transmitter.”

  5. Motors – In most cases, these are brush less electric motors. The motors are usually paired, each pair a set containing one clockwise motor partnered with one counterclockwise rotating motor, though they may be sold individually.

  6. Propellers – Light UAVs use plastic propellers, which resist breaking on impact because they are flexible, and they are safer.

  7. Transmitter – This is the radio controller. For an increasing number of tech toy and entry-level UAVs, the “transmitter” is simply the combination of a mobile app and a Wi-Fi-enabled tablet or smartphone.

  8. GPS – GPS enables flight modes including fixed hovering, auto return home, orientation control, and safety “bubbles” that limit how close the UAV can get to the pilot. GPS also provides an extra level of granularity to further enhance flight stability.

  9. Optical Flow -Optical flow known as Vision Positioning on DJI-based systems is designed to do indoors close to the ground what GPS does outside at higher altitudes.

  10. Obstacle avoidance – While GPS and sensors enable UAVs to basically fly themselves, they work on the assumption of unobstructed air space.

US forces ready a Pioneer drone during Gulf War 1991. Enter into our brief history Israeli aerospace ‘maverick’ Abraham Karem said by many to be the man who invented the Predator drone’. In 1974, aircraft engineer Karem, left Israeli military giant Israeli Aircraft Industries to set up his own UAV business. While the British and US Reaper and Predator drones are physically in Afghanistan and Iraq, control is via satellite from Nellis and Creech USAF base outside Las Vegas, Nevada. Ground crews launch drones from the conflict zone, then operation is handed over to controllers at video screens in specially designed trailers in the Nevada desert. One person ‘flies’ the drone, another operates and monitors the cameras and sensors, while a third person is in contact with the “customers”, ground troops and commanders in the war zone.
