Design of Voice Based Control System for Vehicles/Robot
______________________________________________________________________
Aim: The main aim of this project is to design of voice based control system for vehicles/robot.
Project Description:
This is a latest project in the robot industry. This particular robot will recognize the words and then it is programmed to perform the actions as per the words matched. This project can store about 10 words each of 1.5 millisecond duration. Then in the run mode the computer recognizes the words received by the condenser mike and then matches with the words stored .If the it matches any of the words than the computer gives a data to the micro controller using the RF transmitter. The micro controller receives the data from the RF receiver and will check its database and perform the tasks like move forward means the robot motors runs forward, if they say move backward. The robot wheel will move backward. The robot will move back. If in a big industry there are many robots to do the work, then wirelessly message can be sent to the different robots through voice to do the different operation. For e.g. this project can be used to transport the materials from one place to another place in industries.
