Design, Fabrication and Control of Drone Using Arduino Microcontroller
Quadcopters is an aerial vehicle operated to fly independently and is one of the representation of a UAV (Unmanned Aerial Vehicle). They are controlled by pilots on the ground or simultaneously driven. They are called rotorcrafts because unlike a fixed wing aircraft, here lift is generated by a set of revolving narrow-chord aerofoils. Drones are actually very interesting and in this project we are going to study about them, their components and about its widespread applications that determine its scope for the future. They are the mixture of streams of Electronics, Mechanical and especially Aviation. Drones are of different types and have different configurations for example, bicopters, tricopters, quadcopters, hexacopters, octocopters, etc. They have different uses and accordingly different configurations are used. Hexacopters and Octocopters have better stability and yaw configuration. Control of motion of vehicle is achieved by altering the rotation rate of one or more rotors, thereby changing its torque load and thrust/lift characteristics. Quadcopters have different structures and design according to the work done by it. Components like motors, batteries and electronic speed controllers (ESC's) also vary according to the power needed and work done by quadcopter. Also the enhancements like GPS trackers or cameras or infrared cameras arc used so that they could be applied in various missions like disaster relief, search and rescue, agriculture and 3D mapping of the geography of an area. These widespread applications outshine the advantages which are rectifiable and hence this makes it a very productive technology in today's world. It is supposed to appear in
full existence in the coming years. But every technology has merits as well as demerits.
