Voice Controlled Data Acquisition Car Based on Zigbee Technology
This paper is to design a voice controlled car and use it as a platform for obtaining feedback from a critically controlled environment. The system comprises of a user interface module and a Robocar. The user interface includes an electret microphone through which the voice commands will be accepted by the voice recognition-chip (HM2007). Microcontrollers (PIC16F877A) in the transmitting and receiving side controls the motion of Robocar. The control commands and data are transmitted and received using ZigBee (IEEE 802.15.4).Sensors and transducers are present in the Robocar for collecting application specific datas.
