Control A Robot Using Bluetooth Device

Control A Robot Using
Bluetooth Device
The following project full describes
that how to “Control A Robot Using
Bluetooth” devices. As previous we
have heard or read that the robot is
controlled by mobile phones, GSM
modems and remote controls. Now
we are going to make a robot
controlled by Bluetooth device and
will work in the range of Bluetooth.
The project is based on
microcontroller unit and the
microcontroller can be interfaced with
everything. So before we go to further
part of project I would like to
introduce you all to Bluetooth
technology.
What is Bluetooth Technology?
Bluetooth is an international standard
of wireless technology that provides
better and stable connectivity among
all Bluetooth devices in area of small
range. In a Bluetooth network, two
Bluetooth devices can interact to each
other at a time. One Bluetooth device
of them is called master device and
another is called slave Bluetooth
device.The functionality of master
Bluetooth is to force the another
(slave Bluetooth) device to connect it
and the slave Bluetooth is the device
that waits to receive the network from
master device.
Bluetooth works at a high frequency
of 2GHz to transmit the data.
Function of Bluetooth in this
project:
This project is completely based on
Bluetooth wireless connection. The
master Bluetooth device is connected
to the computer and slave Bluetooth
is connected to the project.The
commands are sent via computer
from master Bluetooth to slave
Bluetooth. To receive the commands
from computer the slave Bluetooth
must be interfaced or connected
correctly to the micro controller unit.
In this project I will not tell that “How
to interface a Bluetooth with
Microcontroller). When the slave
Bluetooth receives commands from
computer it transfers them to the
microcontroller unit and further
actions are taken by the
microcontroller.
The microcontroller unit is perfectly
programmed in assembly or C++
language to perform actions
according to the commands received
from computer master Bluetooth. We
don’t have to understand a typical or
complex circuit about this whole
project. There are many separate
circuit available on the internet that
how the microcontroller unit is
interfaced with all other peripheral
devices.
What is stepper motor:
Stepper motor are commonly used in
the robotics projects. These convert
the electronic pules into the
mechanical energy and force to move
the robot in all directions. The stepper
motor in this project works according
to the instruction of micrcontroller
that are generated according to the
wireless commands sent by master
Bluetooth connected with computer.

The project is very easy to assemble if
you know the following two tasks.
1. Interfacing of Bluetooth with AVR
microcontroller unit.
2. Interfacing of stepper motor with
AVR microcontroller unit.
