The military use of quadcopter has grown because of its ability to operate in dangerous locations while keeping human operators safe. Here, a low-cost hover control mechanism is developed and implemented on a microcontroller. Flight control becomes simpler as the quadcopter hovers at a constant level from ground by itself, at the same time making it too easy to maneuver at heights and perform tasks such as imaging. A PID control method to obtain stability in flying the quadcopter is designed. The model has four input forces which are basically the thrust provided by each propeller connected to each rotor with fixed angle. By varying the speed of rear and front motors, we can obtain the pitch, roll and yaw motions of the quadcopter. Future improvements can be made to improve the design, to prove that it is possible to produce a small scale UAV that can perform functions of interest to the military as well as commercial and industrial applications.
