Unmanned air vehicles
introduction• An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without a human pilot on board. Its flight is either controlled autonomously by computers in
the vehicle, or under the remote control of a pilot on the ground or in another vehicle.
Types of UAVs•Fixed wing UAV.•Helicopter UAV.•Quadrotor UAV.
Rotorcraft
Multirotor
What is quadrotor•A quadrotor, also called a quadrotor helicopter or quadcopter, is a multicopter that is lifted and propelled by four rotors
Why a quad-rotor UAVsQuad-rotor UAVs have many benefits:•Reliable•Compact•Low maintenance
But•Limited payload•Limited flight time•Fast unstable dynamics
Quadrotor advantage over fixed wing vehicle•Less desgin andcomplexity.•Minimal space for take-off and landing.
Quadrotor advantage over helicopter•Quadrotors do not require mechanical linkages.•The use of four rotors allows each individual rotor to have a smaller diameter than the equivalent helicopter rotor
Control of a Quad-Rotor UAV
•Four variable-speed motors control each rotor individually
•Front and aft rotors rotate opposite direction of left and right
•Four-axis Control:•Roll – vary relative speed of left and right rotors•Pitch – vary relative speed of fore and aft rotors•Collective – vary speed of all rotors simultaneously•Yaw – vary relative speed of clockwise and counter-clockwise rotors
•Highly maneuverable, minimal cross-coupling, simple control mechanisms
•Low rate damping, requires electronic stability augmentation
