Unmanned air vehicle(quadrotor)

  1. 1. Unmanned airvehicle(quadrotor)
  2. 2. overview• Introduction• What is unmanned air vehicle• Types• What is quadrotor• applications
  3. 3. Unmanned air vehicles
  4. 4. 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.
  5. 5. Types of UAVs•Fixed wing UAV.•Helicopter UAV.•Quadrotor UAV.
  6. 6. Rotorcraft
  7. 7. Multirotor
  8. 8. What is quadrotor• A quadrotor, also called a quadrotor helicopter or quadcopter, is a multicopter that is lifted and propelled by four rotors
  9. 9. Why a quad-rotor UAVsQuad-rotor UAVs have many benefits:• Reliable• Compact• Low maintenanceBut• Limited payload• Limited flight time• Fast unstable dynamics
  10. 10. Quadrotoradvantage overfixed wing vehicle• Less desgin andcomplexity.• Minimal space for take-off and landing.
  11. 11. Quadrotoradvantage overhelicopter• 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
  12. 12. 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
  13. 13. Control of quad-rotor

  16. 16. UNLIMTED APPILICATION
  17. 17. Unlimited application• Military/Security –Defense• Civil –Defense –Natural Disasters –Humanitarian Relief• Science –Environment –Weather & Storm Tracking• Commercial –Wireless Communications –Precision Agriculture –Cargo Transport
  18. 18. Robot lifting beans and columns
  19. 19. Matlab simulation model
  20. 20. Visual interface
  21. 21. Final model
  22. 22. Thank you•There is no way of telling. Things are moving too fast. No one can predict where it will end.”
