INTRODUCTION TO UAV
THE QUAD-COPTER THEORY
HARDWARE IMPLEMENTATION
SELECTION OF COMPONENTS
OVERVIEW
ADVANCED FEATURES
APPLICATIONS
INTRODUCTION
• Unmanned Aerial Vehicles (UAVs) are crafts capableof flight without an onboard pilot.
• They can be controlled remotely by an operator orcan be controlled autonomously via pre-programmed flight paths.
• Quad-copter is a device with a intense mixture ofElectronics, Mechanical and mainly on theprinciple of Aviation.
THE QUAD-COPTER THEORY…
• Quad-copter uses four propellers, eachcontrolled by its own motor and ESC’s.
• For Hovering:– SUM(Fi) > m•g <=> climb– SUM(Fi) = m•g <=> hover– SUM(Fi) < m•g <=> decline
• Direction of Rotation of Motors:
• Manipulation of Roll, Pitch and Yaw:
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
SELECTION OF COMPONENTS• STATIC THURST CALCULATION:
– Step1: Power transmitted by the motors to the propellersin terms of rpm
– Step2: Thrust produced by a propeller
– Step3:
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.
• DC MOTORS
• This desired rpm will beused in the Propeller andMotor Selection
• FLIGHT TIME:
• A Small demonstration before calibrating the ROLL, PITCH and YAW.
• A Small demonstration after calibrating the ROLL, PITCH and YAW.
ADVANCED FEATURES• Includes some features of autonomous flight
like:– Mission Planning– Way-points– Telemetry– Gimbal– Different Flight Modes
APM…
• MISSION PLANNING: Mission planning is easy with Mission Planner– Mission Planner is a free, open-source software
compatible with APM
• WAYPOINTS: A GPS module is essential forproviding the autopilot with location data thatallows the autopilot to interact with the realworld.
• TELEMETRY: To communicate with the groundstation from the air using the Mavlinkprotocol.
• GIMBAL: ArduCopter support up to 3-axisgimbals and triggering of a camera shutterautomatically.
• 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 controlledto maintain the current altitude.
– Drift Mode: Drift Mode allows the user to fly amulti-copter as if it were a plane with built inautomatic coordinated turns.
– Auto Hold: In Auto mode the copter will follow apre-programmed mission script stored in theautopilot which is made up of navigationcommands (i.e. waypoints).
– Circle Mode: When circle mode is engaged thevehicle will begin flying in a circle with the nose ofthe vehicle pointed towards the center.
– Guided Mode: Guided mode is a capability of todynamically guide the copter to a target locationwirelessly using a telemetry radio module andground station application.
• RTL Mode: In return to launch (RTL) mode, thecopter navigates from its current position to hoverabove the home position.
• Loiter Mode: When switched on, loiter modeautomatically attempts to maintain the currentlocation, heading and altitude.
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
APLLICATIONS• Commercial Uses:
– Quad copters has been in the field of aerial photography.
• Research Platform:– Flight Control Theory– Robotics– Navigation
Now the final flight!!!
