This robotic wheelchair operated by human speech commands. The system operates with the use of a android device which is transmits voice commands to an 8051 microcontroller to achieve this functionally. The transmitter consists of the Bluetooth devices . The voice commands recognized by the module are transmitted by through the Bluetooth transmitter . This commands are detected by the robotic wheelchair in order to move it in left , right ,backward and front direction

3. INTRODUCTION
 This robotic wheelchair operated by human
speech commands.The system operates with
the use of a android device which is transmits
voice commands to an 8051 microcontroller to
achieve this functionally.The transmitter
consists of the Bluetooth devices .The voice
commands recognized by the module are
transmitted by through the Bluetooth
transmitter .This commands are detected by the
robotic wheelchair in order to move it in left ,
right ,backward and front direction

4. HARDWARE SPECIFICATION
 8051 series microcontroller
 Arduino
 Motor driver IC
 Battery
 DC motor
 Robot body
 Crystal
 Voltage regulator
 Bluetooth device

5. SOFTWARE SPECIFICATION
 Keil uVision IDE
 MC programming language
 Android app

7. 8051 SERIES MICROCONTROLER
 A micro controller can be compared to a
small stand alone computer , it is very
powerful device, which is capable of
executing a series of pre-programmed tasks
and interacting with other hardware devices.
it is becoming the perfect controller for
robots or any machines requiring some kind
of intelligent automation

9. ARDUINO
 An Arduino board historically consists of an
Atmel 8,16,or 32 bit AVR microcontroller with
complementary component that facilitate
programming and incorporation into other
circuits.
 An important aspect of the aurdino is its
standard connectors, which let users connect
the CPU board to a variety of interchangeable
add- on modules termed shields.

10. MOTOR DRIVER IC
 Motor Driver ICs are primarily used in
automatics robotics only . Also most
microprocessors operate at low voltages and
require a small amount of current to operate
while the motors require a relatively higher
voltages and current .thus current cannot be
supplied to the motors from the
microprocessor .this is the primary need for
the motor driver IC

12. AUTOMATIC VOICE CONTROL WHEELCHAIR

13. BLUETOOTH DEVICE
 Here we use HC05 Bluetooth module .
 The HC05 modules are very clever pieces of
hardware , as they translate incoming Bluetooth
communication to serial data. So once
configured this gives the tinkerer the possibility
to achieve serial communication over Bluetooth .
 The HC 005 acts transparently, meaning that you
just communicate with the serial port it is
connected to and the module then sends/
receives via Bluetooth

14. WORKING
 This project automatic voice controlled robotic
wheelchair helps to control robot through voice
commands received via android application .
 The integration of control unit with Bluetooth device is
done to capture and the read the voice commands .
 Then it operates as per the command received via
android application.
 For this 8051microcontoller is integrated in the system
which make it possible to operate the robot via android
application .

15. CONTI....
 After receiving the commands , the
microcontroller then operates the motors when
we order to move the robot in four directions.
The communication between android device and
receiver is sent as serial communication data .
The microcontroller program is designed to
move the motor through a motor driver IC as per
the commands by the android device .And
android device send command for right, left,
backward and front direction.

16. APPLICATION AND ADVANTAGE
 The robot is small in size so can be used for
spying.
 With few additions and modification , this
robot can be used in the borders for detecting
and disposing hidden land mines.
 This can be used for reconnaissance or
surveillance

17. CONCLUSION
 In this project we work on automatic voice
control robotic wheelchair . For this project
mainly we use 8051microcontroller and HC
05 Bluetooth module. And some android
application for programming .
 This is total based on social purpose .
