Construction of Quadcopter

  1. 1. Construction of a Quadcopter B.Tech Aerospace Engineering Semester (5) Practical Evaluation-1 Faculty Guide: Mr. Sarath Raj Quadcopter Technology By: Michael Bseliss
  2. 2. Index • Introduction • Components of a Quadcopter • Quadcopter Flight Control • Applications of Quadcopters • Advantages & Disadvantages • Conclusion
  3. 3. Introduction What is Quadcopter ?!
  4. 4. What is Quadcopter ?! A quadcopter or a quadrotor helicopter is a multirotor copter that is lifted and propelled by four rotors.
  5. 5. A quadcopter uses 2 sets of identical fixed pitched propellers; 2 clockwise (CW) or in one direction and 2 counter-clockwise (CCW) or opposite direction What is Quadcopter ?!
  6. 6. Quadrotor’s all four rotors work together to produce upward thrust and only 1/4 of the weight is lifted by each rotor. So less powerful motors are used, making it cost efficient. What is Quadcopter ?!
  7. 7. 1) Frame 2) Propellers 3) Electric motors 4) Battery – Power Source 5) ESC- Electronic Speed Controller 6) Radio Transmitter and Receiver 7) Flight Controller Components of a Quadcopter 8) MicroController & Inertial Measuring Unit
  8. 8. Components of a Quadcopter The Frame
  9. 9. Components of a Quadcopter The structure that holds or houses all the components together. They are designed to be strong and lightweight. Weight Size Materials used The Frame
  10. 10. It consists of 3 parts : • The center plate where the electronics are mounted • Four arms mounted to the center plate • Four motor brackets connecting the motors to the end of the arms Components of a Quadcopter The Frame
  11. 11. Components of a Quadcopter The Frame Frames are usually made of: • Carbon Fiber. • Aluminum. • Wood/ Plywood /MDF (Medium-density fiberboard)
  12. 12. 4 propellers, 2 “normal” CCW , 2 “pusher” CW Components of a Quadcopter The Propellers
  13. 13. They are a bit similar to normal DC motors in the way that coils and magnets are used to drive the shaft Components of a Quadcopter Electric Motors
  14. 14. LiPo (Lithium Polymer) batteries are used because it is light. NiMH (Nickel Metal Hydride) is also possible. Cheaper but heavier. Components of a Quadcopter Battery – Power Source
  15. 15. Controls the speed of the motor. Motors must all spin at precise speeds to achieve accurate flight, so that ESC is very important Components of a Quadcopter ESC- Electronic Speed Controller
  16. 16. Four channels for a basic quadcopter is required Components of a Quadcopter Radio Transmitter and Receiver
  17. 17. The ‘brain’ of the quadcopter Components of a Quadcopter Flight Controller
  18. 18. To decide on how to control the motors. IMU is the electronic sensor system which measures velocity, orientation and gravitational forces of the quadcopter. Components of a Quadcopter MicroController and Inertial Measuring Unit
  19. 19. Such as GPS modules, cameras, ultrasonic sensors, barometers..etc Components of a Quadcopter Extended Options
  20. 20. Quadcopter Flight Control
  21. 21. Quadcopter Flight Control
  22. 22. Quadcopter Flight Control
  23. 23. Quadcopter Flight Control
  24. 24. Quadcopter Flight Control
  25. 25. Quadcopter Flight Control
  26. 26. Quadcopter Flight Control
  27. 27. Quadcopter Flight Control
  28. 28. Applications of Quadcopters 3-D Mapping Search and Rescue Farming & Monitoring Environmental Conditions Capturing photos for events (sport match) Inspection of Building & Monitoring Construction Projects
  29. 29. Advantages of Quadcopters  Four small rotors have smaller diameter than one large helicopter rotor.  Takes less damage to rotors.  No need for a tail rotor which generates no lift.  Easier to build four small blades compared to large one.  They can traverse through difficult terrains because of their small size and there is less risk of damage too.  They are significantly cheaper and the cost in fuel and maintenance is way lower than regular airplanes.
  30. 30. Disadvantages of Quadcopters  Drones also contain limitations. For instance, they cannot communicate with civilians for more detailed intelligence.  According to civilians drones are viewed as an invasion force.  Battery power may be restricted and may require frequent charging.  The worst scenario is when drones or a fleet of drones have been commandeered or taken control by the enemy.
  31. 31. Conclusion
  32. 32. Q & A
  33. 33. Thank You !!
