Introduction

Voice controlled wireless Robot is a robot whose movement can be controlled by giving different instruction from a user using windows speech recognition software. The robot can move forward, backward, right, left, clockwise, anticlockwise depending upon the instruction you are pressing. The property of Robot to operate through a PC in wireless mode helps you to operate the robot from some distance. The benefit is that we can operate the robot by using any Windows PC from very short range to the range as large as possible depending upon the module used.

II. Burning the Micro controller (IC Atmel 328) through Arduino UNO and Using it

The heart of this project is Micro controller Atmel 328 which is programmed through a Arduino UNO board. This programming is done usually to make micro controller capable of serial communication with the PC such that voice commands can be passed to the IC so that further processing can be done.

The code for Arduino Software is as follows:

Fig. Connect the Board with PC while Burning

After Burning the IC you can Disconnect the Board from the PC and start using the Board in following way:
