This document summarizes a student presentation on the design and implementation of an autonomous quadcopter. It describes adding sensors to measure temperature, humidity, CO2, and include real-time monitoring. The quadcopter uses a custom GPS system for autonomous flight controlled by an Android device. It can automatically takeoff and land using DroneKit software. The presentation team aims to add image recognition using OpenCV and automatic landing detection of specific patterns. They also want to add obstacle detection during flight.

3. Motivation
• In 2006, Tayebi & Madani published a paper on IEEE about “vision based
guidance and control of hovering vehicle in unknown gps denied environment.
• In 2011 jianzhi zhang published a paper on IEEE about “Autonomous navigation
for an UAV in urban area”.
• In 2016, wang, Suzuki, Nomani published a paper on ICAS about “ Autonomous
UAV lading system” .
• Learn about unmanned Aerial Vehicle(UAV).
• Implementation of A.I for controlling the Quad copter.
• We are inspired by Amazon Prime Air delivery system

4. Introduction
 Quad copter is a Unmanned Aerial Vehicle with a intense mixture of Electronics, Mechanical
and mainly on the principle of aviation.
 It is a multirotor helicopter that is lifted and propelled by four rotors. It also called as
quadrotor helicopter or quadrotor or drone.
 Controlled remotely by an operator.
 Over the last few years we have seen a massive growth in the manufacture And sales of
remote control airborne vehicles known as quadcopter.
 The utilization of unmanned vehicles has become increasingly more popular today and been
successfully demonstrated for various civil and military applications.
 The rapid advances in computing power, the efficiency of the coreless or brushless motors,
smaller microprocessors the development of batteries.

5. Working Principle
 In a quad copter there are four motors placed at the edge of four
arms of the frame.
 The propeller on the quad copter generate a lift in order to get of
the ground and able to hover fly around.
 The thrust force must be grater than the weight of the quad copter.
 The principle and working of propeller in a quad copter Is based
on Bernoulli’s principle and Newton’s third law.

10. System Components
A. Frame
Frame is the skeleton of any quadcopter. Every
component of a quadcopter are organized on
this frame. Frame shape can be X,H and +. For
our project we use + shaped frame. The reason
behind to use this shape is its low cost and it is
easily available. We used carbon fiber frame
instead of steel frame because of it’s light
weight which can carry more payload.

11. System Components
B. Motor
Brushless DC Electric motor also known as
electronically commutated motors.
Brushless motors are synchronous electric
motors that move around electronically.
They utilize direct current powering
magnets to move the rotors within the
stator. It creates a rotation that in turn
converts electrical energy into mechanical
energy unlike the brushed or conventional
motor.

12. System Components
D. ESC
ESC stands for Electronic Speed
Controller. There are four ESC’s used
in our quadcopter which are
connected to four brushless motors. It
controls the speed of the motors. The
ESC receives throttle signal from the
flight controller and drives the
brushless motor at optimal speed by
providing the appropriate level of
electrical power.

13. System Components
E. Flight Controller
Flight Controller is called the brain of
the quadcopter. It is basically a circuit
board with sensors and electronic
components that detects orientation
changes of a quadcopter. It has also a
receiver which receives user commands
and control the motors in order to keep
the quadcopter in the air. The
quadcopter flight controller is basically
the point of contact between the device
and user.

14. System Components
G. Raspberry pi
The Raspberry Pi is a low cost, credit-
card sized computer that plugs into a
computer monitor. It is a capable little
device that enables people of all ages to
explore computing, and to learn how to
program in languages like Scratch and
Python. It’s capable of doing everything
people would expect a desktop computer
to do, from browsing the internet and
playing high-definition video, to making
spreadsheets, word-processing, and
playing games.

15. System Components
C. Propeller
Propeller is basically a type of fan which
can be called rotors or props. It is one
kind of mechanical device. Two types of
rotors are used in quadcopter. In four of
the rotors two of them spin clock-wise
and two of them spin counter clock-
wise. The purpose of any quadcopter
propellers is to generate thrust and
torque to keep the drone flying and to
maneuver.

16. System Components
H. Battery
The battery we used in our quadcopter is
called LiPo battery or Lithium Polymer
Battery. They have higher capacities which
allows them to hold more power and have
higher discharge rates allowing faster
power transfer. LiPo batteries are lighter
and can be made in different shapes and
sizes.

17. System Components
F. GPS
Global Positioning Systems (GPS) use
the signals sent by a number of
satellites in orbit around the earth in
order to determine their specific
geographic location. A GPS quadcopter
or GPS drone can demonstrate greater
stability in such conditions, allowing
user to combat those more adverse
weather conditions when flying. It can
be particularly useful for aerial
photography and video capturing
purposes.
