The main aim of this paper is to develop an efficient and low cost voice guided robot that navigates based on the voice signals given by the human users using LabVIEW 2011 for speech recognition and RF module for wireless transmission. The module is aimed at navigating in environments with noise and other disturbances very effectively. The speech recognition is based on LabVIEW 2011 .NET frameworks and the VI designed is highly flexible and can suit to large variety of applications where in the

... changes are to be in the microcontroller programming and the hardware requirements which are relevant to the application being designed. The communication to the hardware has been established via RS232 cables using microcontrollers to the transmission kit and the RF signal to communicate with the receiving kit mounted on the mobile robot. Unlike the costly DAQs these hardware communication are highly cost effective and the systems are flexible and can be altered to any utility. Adequate measures are taken to reduce the problems of external disturbances like noise etc. so that the module will understand the command even in very noisy environments. The purpose of these modules is to reduce the human loss due interventions in hazardous environments such as probation of life under debris, bomb detection in target sites etc.
