Over the last few years we have seen a massive growth in the manufacture and sales of remote control airborne vehicles known as quadcopter.

Quad copter is also known as Drone. These unmanned aerial vehicle have four arms and fixed pitch propellers which set in a ‘x’ and ‘+’ modes. In the standard format two propellers will spin in a clock wise direction with other spinning in an anti-clock wise direction allowing to fly in a designated direction.

Working:

Quad copter has four motors whose speed of rotation and the direction of rotation changes according to the user’s desire to move the device in particular direction take off motion, landing forward motion, backward motion right motion.

The rotation of motor changes as per the transmitted signal the form the four channel transmitter.

The signal from micro controller goes to ESC which in turn controls the speed of motor the program for which is written in the ATMEGA 16 chip.

Real time Applications:

• News Making
•  Agriculture
  
•  Delivery
  
•  Photography / Videography
  
• Military

Pros:

• Helps to detect forest fires
•  Monitor environmental data(i.e. population of animals)
  
• Can seek missing children and felons

Cons:

•  Domestic drones violate right to privacy
  
•  Some drones are lethal and not just used for surveillance
  
• With drones being unmanned flying machines, less aviation jobs are needed. They’re very expensive and a rarity among the world.
