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

HARDWARE SPECIFICATION

8051 series microcontroller Arduino Motor driver IC Battery DC motor Robot body Crystal Voltage regulator Bluetooth device

SOFTWARE SPECIFICATION

Keil uVision IDE MC programming language Android app

BLOCK DIAGRAM

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

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.

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

AUTOMATIC VOICE CONTROL WHEELCHAIR

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

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 .

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.

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

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 .
