The quad-rotor helicopter (quadcopter) is a fully functional, remote controlled aerial unit. These days, quadcopters are used in various ways as everything from surveillance drones to children’s toys. It is made of up of a frame with landing legs, four motors which connect to propellers and support the weight of the unit. A control system (the “stabilizer”) takes in input from the environment to determine if speed compensation is necessary from one rotor or another to keep the unit level. Beyond the level compensation, input is read from a 2.4 GHz transmitter by a receiver bringing the quadcopter to life.
