Transcript of Bluetooth Controlled Robot using Android Phone For

It provides the tools and abilities to design and implement environmental-friendly and low-cost applications which can operate and communicate in mobile environments, in the optimal
case using only a single chip.
Bluetooth
Bluetooth is a protocol for wireless device communication, which is intended and optimized for short distances.
Introduction
Android devices are powerful mobile computers with permanent internet connectivity and a rich variety of built-in sensors.
Background of the Study
The following chapter is designated to give a short introduction into Bluetooth Technology for readers unfamiliar with the topic. Following up, the connection establishment process as well as the Bluetooth Low Energy stack and its most important underlying layers of the Bluetooth stack get explained. Furthermore, a short explanation of the hardware devices used in this project is given.

Bluetooth Low Energy
Bluetooth Low Energy (BLE) is an extension to the Bluetooth 4.0 standard. It got introduced by the SIG in late 2009 and is optimized "specifically (for) small battery operated devices that require almost no power" . Devices supporting BLE communication are certified as Bluetooth Smart Devices by SIG.
A big advantage to classic Bluetooth is the much lesser power consumption of BLE devices, which is made possible through a much simplified device discovery and connection establishment process, as well as the short activity window of BLE devices, usually only sending small data packets every several seconds and going to sleep mode in between.
BLE devices act on a certain network concept called Pico net and must adopt certain roles which define their actions and abilities within the communication.
BLE layers
The Bluetooth standard itself is not a single protocol, but provides a stack with lots of Different layers acting similar to the TCP/IP network stack. On the higher-abstraction levels, these layers are often also called profiles.
There is a wide range of existing layers and profiles specifically design for certain uses for example in health or sports applications, hence the following listing just shows up the ones that are important for the scope of this thesis.
The Bluetooth Low Energy protocol stack


The Bluetooth Low Energy network stack can be divided into two subparts, the controller stack, which is containing the interface dealing with the radio transmission, and the host stack, which is working on more high level data.
The Bluetooth Robot
The Bluetooth Robot Kit is a development kit mainly intended for the construction of robots participating in surveying a particular place.
It is developed and distributed by PUP Institute of Technology and contains all the necessary parts for developing a full-functioning robot vehicle, but can easily be extended by additional parts. The contents of the development kit are as follows.

Torque DROIDZ Atom X
The Droidz Atom X (furthermore also simply referred to as Torque mobile) is a popular smartphone, developed and published in 2014 by Torque Inc. It is currently one of the best-selling mobile phones in the philippines, based on the 1GHz DUAL CORE CPU and featuring among other things a multi-touch input system, two inbuilt cameras, a 4.2 Jellybean and 4GB ROM.
Theoretical Framework
Bluetooth is a high-speed, low-power microwave wireless link technology, designed to connect phones, laptops, PDAs and other portable equipment together with little or no work by the user.
Conceptual Framework
An Android controlled Segway (inverted pendulum principle). For real world results concerning the Bluetooth induced latency, an Android controlled Segway would be very interesting to develop.
Statement of the Problems
In this thesis, I will answer the following questions:
1. What is the application of Bluetooth technology? What are the advantages of
using Bluetooth? And how does it compare with other available technologies.


2. What is driving the deployment of Bluetooth? Both from the perspective of a user and
that of the industry.
3. What are the general security issues in wireless technology and in specific
what are the security issues in Bluetooth?
what are the security issues in Bluetooth?
4. Demonstrate with a use case / case study, how Bluetooth can be used in a
practical scenario?

Statement of the Problem
Scopes and Limitations of the Study
1. Slow Transfer Rate
o The rate of data transfer between Bluetooth devices is about three megabits per second. This is significantly lower than Wi-Fi, the other predominant wireless technology, which transfers at 54 Mbps. Bluetooth is also too slow to stream music
or video, which requires at least 10 Mbps.

The new Bluetooth standard, Bluetooth 3.0, will allow for transfer speeds of up to 24 Mbps by using a Bluetooth connection to set up a separate Wi-Fi connection. This combination of Bluetooth and Wi-Fi technology allows the connection rate of 24 Mbps.
Scope and Limitations
Scope and Limitations
Distance Limitations
o Most Bluetooth devices, especially those that run on battery power, are Class 2 Bluetooth devices. Class 2 devices have a range of about 10 meters, or around 30 feet.

.
Scope and Limitations
Interference
o Bluetooth devices work with the 2.4 GHz radio band, which is the same unlicensed frequency used by many other wireless devices.
Significance of the Study
1. The robot is small in size so can be used for spying.
2. With few additions and modifications, this robot can be used in the borders for detecting and disposing hidden land mines.
3. The robot can be used for reconnaissance or surveillance.
