Autonomous Quadcopter for Product Home Delivery Md R Haque, M Muhammad, D Swarnaker and M Arifuzzaman Department of Aeronautical Engineering, Military Institute of Science and Technology Dhaka, Bangladesh. ABSTRACT This paper represents Quadcopter (QC) as a low-weight and lowcost autonomous flight capable Unmanned Aerial Vehicle (UAV) for delivering parcel ordered by online by using an android device as its core on-board processing unit. Therefore, this method is independent from additional ground hardware and if required, QC core unit can be easily replaced with powerful hardware to simplify setup updates and maintenance. This QC by following Google map can locate and navigate destination. This paper demonstrates the QCs capability of delivering parcel ordered by online and coming back to the starting place. The promising result of this method enables future research on using QC for delivering parcel using mobile hardware as the only on-board processing unit. PRINCIPLE OF OPERATION ON BOARD CONTROL SYSTEM  All four rotors are located within the same plane and oriented such that the thrust generated by each rotor is perpendicular to the vehicle  The angular momentum of any of the four rotors generates a torque about the inertial center of mass of the vehicle which can be effectively counterbalanced by the torque created from the opposing rotors spin.  There are two types of opposing rotors configuration: “+”configuration and “x” configuration. The QC is unable to perform at long distance range due to limited amount of power supply from Lithium polymer battery. Increment of power source will increase the range. But at the same time it will raise the empty mass resulting low payload capacity. Besides, it may exceed the maximum mass limit; the QC is capable of flying. For this reason, the paper is proposing to serve only one customer at a time. Furthermore, a lot of QCs deployed in a single area needs an air traffic management system which requires further research. CONCLUSION This paper deals with a systematic process of online delivery with an autonomous QC using an interfaced android device as its core processing unit. QC will deliver the parcel to the customer by following Google map which will reduce both time and manpower using for delivery. Battery power will be replaced by solar system as a power source in future. This process will be continued to optimize the cost of delivering products through QC so that poor people can use these systems more easily. OBJECTIVE AND OVERVIEW OF OPERATION The main objective is to ensure timely delivery of products by using autonomous QC. After the order has been placed, QC will be loaded with the product. Then, QC will start to fly towards its given direction by following GPS map. After reaching its desired location it will confirm its customer and drop the parcel and get back to the starting point through the same route. Complete operation of delivery service via QC can be categorized by following phases shown in figure below: LIMITATIONS & SCOPE OF FUTURE RESEARCH REFERENCE STRUCTURAL & ELECTRICAL COMPONENT OFF BOARD CONTROL SYSTEM QC is designed to have four arms which provide the body a stable balance. Each arm is associated with one motor of 3350 rpm/v comprising total four motors. Each motor is associated with one propeller of APC electronic E series of 14 inch diameter and 10 pitch. Each motor is connected with one Electronic Speed Controller (ESC). Off board control system consists of a computer of the control room of the local office and the mobile phone of the user. The computer of the control room provides necessary data to the GPS in the QC after. Computer of the control room will also monitor the position of the QC during transportation via GPS with the help of internet. PERFORMANCE TESTING To estimate the flight time of the QC with various loads, actual flight test has been done with loads ranging from 0 grams to 300 grams. The results of the test are shown in Table-II. During the test the QC was flown at approximately fifty feet off the ground performing stabilize flight. A plot of this information provides a relationship between the payload and the flight time and can be seen in figure.
