Flight
A Quad copter is the most commercialised version of drones today. The drones fly using their blades and motors (one on each side), which propel them into the air. The blades - similar to normal fans - make the drone fly faster and higher depending on their speed. The blades are pushing wind beneath them which will launch the drone higher. Most drones have some basic functions: Hovering, Flying up and down, Moving backwards and forwards and turning different directions.
When the drone hovers it equals the upward thrust of the blades and motors to match the downward pull of gravity so that it will stay in place without moving up and down. However, once either of the two forces exceed the other the drone will begin to move up or down. This works in accordance with Newton’s Law of Motion “For every action, there is an opposite and equal reaction.” This means that if the first object exerts a force then the second object exerts the same force onto another object.
The turning motion of the drone is performed when two of the motors (1 and 3 or 2 and 4) are turned off causing the drone to spin the direction of the blades. Each set of the blades spin in opposite direction which is why it is important that there is one blade on each side spinning anticlockwise and clockwise. Newton’s first law states that an object will remain in uniform motion in a straight line unless it is compelled to change its state by forces compressed on it which is why the motors are balanced on each side. For example, if the green blades turned off (refer to diagram) the drone would begin to turn anti-clockwise.
These are all represented in coding by certain phrases. When coding you need to use terms so that your code works: Yaw, Pitch and Throttle. The throttle is the speed the drone flies at. If the drone is not angled(pitch) forward or backwards then the drone will just continue to rise up. The Yaw is what controls the way the drone spins. If the yaw is positive then it will turn right and the higher it is the faster it turns, however the yaw is a negative number then the drone will turn left and the lower it is the faster it turns left. Finally the pitch is the angle at which the drone actually flies at. This is how the drones moves forwards, backwards and side to side. This determines whether the drone will fly upwards or down depending on the angle it is at.
If one of the 4 motors changes speed than the drone will start turning in direction that has slowed. There are two ways this can be used. The first example is if the two right motors were given more power - the more power the quicker it goes - than the left side the drone would tilt (the right side would be the higher side) and move to the left.

The First Drone (Kind of
The first ever drone was nothing like the typical drone today. The drones had no technology or even wings. In 1839, Austrians attacked Venice using unmanned balloons which were rigged up with explosives. The very first “Drone” shaped part of today’s modern warfare. 60 years later the Wright brothers created the very first plane, which soon became the most common aerial vehicle. With this advancement, the British were eager to create an unmanned version.
The Americans
The Americans had more foresight, however, and started on their own project and after many prototypes they settled on the Kettering Bug. This Drone was way more advanced than anything else created in 1918, disappointingly it never graced the battlefield as the war had already ended.
The Technology was further improved throughout WWII all the way into the cold war. The only issue was that they were so expensive they were seen purely as a novelty. Manned aircrafts were still the most popular aerial attack after the Sr-71 Blackbird was invented. It is believed that they were still used as a viable way to spy on the enemy by the US and Russia, however it is still unknown.
The First Advancement
Only 16 years later when the British created The Ruston Proctor Aerial Target, which was based on Nichola Tesla’s designs. The technology was similar to the technology of today except is was very undeveloped. The Drone meant as a bomb that would help counter against Germany’s Zeppelins. Unfortunately, the project was scrapped after several prototypes failed to launch. Britain concluded that the use of UAVs would be very limited in future military combat.
Commercial
Commercial drones are only a recent thing however they have skyrocketed over the past 6 years or so. They can be purchased at just about any store that has a technology section. With these advancements the Government has also had to put laws surrounding where a drone can fly and other restrictions. Companies such as amazon are trying to implement the use of drones as a viable way to deliver packages faster. The future of drones is boundless. Drones can be used in lifesaving, beach patrol, delivery and many more ways.
Israel
1982, was the start of the drones we know and love today. Israel commanded the use of drones to eliminate a syrian fleet without any losses in lives and resources. It was furthered used to distract, jam communications of the Syrians and find their position by the Israelis to prevent the further loss of life.
Israel wasn’t using any ground breaking technology, as most countries had access to the technology however the Israel army used the drone in a way that had never been explored. This advancement had sparked a new interest into drone and subsequently America spend tens of millions on the research and further progression of drones. Hence, technology and hardware used did progress significantly in the following years
