Abstract

The purpose of this article is to presents the implementation and design of a high level communication interface based on multi agents model for a set of autonomous robots. Classical techniques, used in speech recognition which are zero crossing and extremes, dynamic time warping and different features such as Mel frequency Cepstral coefficients, delta MFCC, Energy and LPC are merged in order to increase the rate of recognition, followed by a decision system based on independent methods test results, are used as a speech recognition agent. Two consecutive agents; namely syntactic and semantic agents, are added to improve the recognition rate and improve the human-machine communication language. To implement the approach for tele-operating a set of robots on a real time, a Personal Computer interface was designed based on Bluetooth wireless communication modules to control the movement of a set of robots using high level language. The voice command system for four autonomous robots is designed however the robot navigation techniques are not discussed in this work. The main parts of the robots are based on a microcontroller from Microchip PIC18F2450, a set of sensors modules and a Bluetooth module.
