1. 1. UNMANNED AERIAL VEHICLE Girija sankar dash EMBETICS SOLUTIONS
2. 2. INTRODUCTION TO UAV THE QUAD-COPTER THEORY HARDWARE IMPLEMENTATION SELECTION OF COMPONENTS OVERVIEW ADVANCED FEATURES APPLICATIONS
3. 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.
5. 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. 6. • Direction of Rotation of Motors:
7. 7. • Manipulation of Roll, Pitch and Yaw:
8. 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. 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. 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. 11. • DC MOTORS • This desired rpm will be used in the Propeller and Motor Selection
12. 12. • FLIGHT TIME:
13. 13. • A Small demonstration before calibrating the ROLL, PITCH and YAW.
14. 14. • A Small demonstration after calibrating the ROLL, PITCH and YAW.
15. 15. ADVANCED FEATURES • Includes some features of autonomous flight like: – Mission Planning – Way-points – Telemetry – Gimbal – Different Flight Modes
16. 16. APM…
17. 17. • MISSION PLANNING: Mission planning is easy with Mission Planner – Mission Planner is a free, open-source software compatible with APM
18. 18. • WAYPOINTS: A GPS module is essential for providing the autopilot with location data that allows the autopilot to interact with the real world.
19. 19. • TELEMETRY: To communicate with the ground station from the air using the Mavlink protocol.
20. 20. • GIMBAL: ArduCopter support up to 3-axis gimbals and triggering of a camera shutter automatically.
21. 21. • 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.
22. 22. – 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).
23. 23. – 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.
24. 24. – 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.
25. 25. • RTL Mode: In return to launch (RTL) mode, the copter navigates from its current position to hover above the home position.
26. 26. • Loiter Mode: When switched on, loiter mode automatically attempts to maintain the current location, heading and altitude.
27. 27. 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
28. 28. APLLICATIONS • Commercial Uses: – Quad copters has been in the field of aerial photography. • Research Platform: – Flight Control Theory – Robotics – Navigation
29. 29. Now the final flight!!!
