APPLICATIONS

3. INTRODUCTION
• Unmanned Aerial Vehicles (UAVs) are crafts capable
of flight without an onboard pilot.
• They can be controlled remotely by an operator or
can be controlled autonomously via pre-programmed
flight paths.
• Quad-copter is a device with a intense mixture of
Electronics, Mechanical and mainly on the
principle of Aviation.

4. THE QUAD-COPTER
THEORY…

5. • Quad-copter uses four propellers, each
controlled by its own motor and ESC’s.
• For Hovering:
– SUM(Fi) > m•g <=> climb
– SUM(Fi) = m•g <=> hover
– SUM(Fi) < m•g <=> decline

6. • Direction of Rotation of Motors:

7. • Manipulation of Roll, Pitch and Yaw:

8. HARDWARE IMPLEMENTATION
• Quad-Board
• Propellers
• BLDC Motors
• 2.4 Ghz Transmitter And Receiver
• Electronic Speed Controllers (ESC)
• Gyroscope
• Accelerometer
• A Strong Base As To Hold The Structure

9. SELECTION OF COMPONENTS
• STATIC THURST CALCULATION:
– Step1: Power transmitted by the motors to the propellers
in terms of rpm
– Step2: Thrust produced by a propeller
– Step3:

10. SELECTION OF COMPONENTS
– Step4: The power that is absorbed by the propeller from
the motor
– Step5:
– Step6:Newton’s Law, F=ma, is used to obtain equation 6.

11. • DC MOTORS
• This desired rpm will be
used in the Propeller and
Motor Selection

12. • FLIGHT TIME:

13. • A Small demonstration before calibrating the
ROLL, PITCH and YAW.

15. • A Small demonstration after calibrating the
ROLL, PITCH and YAW.

17. ADVANCED FEATURES
• Includes some features of autonomous flight
like:
– Mission Planning
– Way-points
– Telemetry
– Gimbal
– Different Flight Modes

18. APM…

20. • MISSION PLANNING: Mission planning is easy
with Mission Planner
– Mission Planner is a free, open-source software
compatible with APM

21. • WAYPOINTS: A GPS module is essential for
providing the autopilot with location data that
allows the autopilot to interact with the real
world.

22. • TELEMETRY: To communicate with the ground
station from the air using the Mavlink
protocol.

23. • GIMBAL: ArduCopter support up to 3-axis
gimbals and triggering of a camera shutter
automatically.

24. • DIFFERENT FLIGHT MODES:
– Acro Mode: When the control sticks are released
the vehicle will remain in it’s current attitude.
– Altitude Hold: When altitude hold mode is
selected, the throttle is automatically controlled
to maintain the current altitude.
– Drift Mode: Drift Mode allows the user to fly a
multi-copter as if it were a plane with built in
automatic coordinated turns.

25. – Auto Hold: In Auto mode the copter will follow a
pre-programmed mission script stored in the
autopilot which is made up of navigation
commands (i.e. waypoints).

26. – Circle Mode: When circle mode is engaged the
vehicle will begin flying in a circle with the nose of
the vehicle pointed towards the center.

27. – Guided Mode: Guided mode is a capability of to
dynamically guide the copter to a target location
wirelessly using a telemetry radio module and
ground station application.

28. • RTL Mode: In return to launch (RTL) mode, the
copter navigates from its current position to hover
above the home position.

29. • Loiter Mode: When switched on, loiter mode
automatically attempts to maintain the current
location, heading and altitude.

30. APLLICATIONS
• Military Uses:
– Unmanned Arial Vehicle are used for surveillance
and reconnaissance by military and law
enforcement agencies
– search and rescue missions in urban
environments

31. APLLICATIONS
• Commercial Uses:
– Quad copters has been in the field of aerial
photography.
• Research Platform:
– Flight Control Theory
– Robotics
– Navigation

32. Now the final
flight!!!
