Objective• UAV VTOL’s are small in size and easy in operation.• Highly efficient, low cost and high thrust output. • No need of runway for this vehicle, this vehicle can easily take

vertical lift.• Easily moves to the congested places.• The UAV’s are designed to fly at low altitudes normally less

than 1000 meters to give a close observation of the ground objects.

• UAV’s are also implemented in civilian works such that mapping, traffic control, search and rescue operation.

Deliverables• VTOL body• Arduino microcontroller • Xbee Module• GUI

Block Diagram

Major Components• GPS• Arduino 2560• 10DOF sensors (Gyro, Accelerometer, Barometric pressure

sensor)• Xbee Module• Wireless Transmitter /Receiver• Propeller• DC Brushless motor • 9g Servos • ESC

GPS (Global positioning System)• We have used skm53 GPS• It gives latitude and longitude of the vehicle• Tiny GPS library is used in micro controller• May have following possibilities for weak signals• 1.Bad weather rarely• 2.Tall Buildings• 3.Non availability of satellites• 4.Indoor use

Data Pattern

Microcontroller• The Arduino Mega 2560 is a microcontroller board based on

the ATmega2560.• 54 digital pins• 16 analog pins• 4 UART s• 16 MHz Crystal

10DOF• 10 DOF means ten degree of freedom.• It includes 3 axis Accelerometer, 3 axis Gyro sensor, 3 axis

magnetic sensor (not using), BMP• Gyro used for Roll, Pitch and Yaw.• Accelerometer used for calculation of gravitational

acceleration in 3 axis• BMP used for measurement of temperature, pressure and

height form sea level

XBEE MODULE• Indoor range: 30 meter• Outdoor range: 90 meter• Power: 1 mw • Operating frequency: 2.4 GHz• Data transmitted from VTOL vehicle is received at ground

station Xbee receiver• Xbee receiver feeds data into serial port using RS-232 circuit• Data is acquired in Lab view

Contd..• Transmitter /Receiver FUTABA 6 channel radio transmitter andreceiverFrequency: 2.4 GHz.

• Electronic Speed Controller (ESC)Model: 40-50A ESCElectrically powered radio control device.

• Servo motors 9 gram Volt: 3-6v

Contd..• Brushless DC Motor50 gram, 342 W,7.4 – 11.1 V

• Li-Po Battery3 Cell / 11.1V129g (weight)

Propeller• 6 X 4 propeller• 6 length• 4 pitch• 1 kg thrust generates

Basic Aerodynamics•A plane in air exhibits following properties• 1.Roll • 2.Pitch • 3.Yaw • 4.Thrust• 5.Drag

Weight Calculation • LiPo Battery = 129 g • ESC = 39 g• Brushless dc motor = 50 g• Servo motors = 11 g each• Circuit Module =170 g • Body weight = 190 g• Total weight = 600 g
