VEHICLE NAVIGATION AND OBSTACLE DETECTION SYSTEM USING RFID AND GSM
S. Saravanan, T. Kavitha · 2012
An autonomous mobile vehicle needs to be developed to allow the vehicle to reach the desired destinati on using tracking and obstacle detection schemes. This paper concentrates on the vehicle navigation and obstacle detection. Vehicle navigation is carried o ut using Radio Frequency Identification (RFID) technology. It is used to navigate the vehicle from source to destination. The obstacle detection is carried out using ultrasonic sensor. If any obstacles are d etected, the information is sent to the operator wh o navigates the vehicle through Global System for Mobile communication (GSM). The entire system is controlled by an efficient low cost version of PIC microcontroller (16F877A). On the whole, the system suits well for industrial goods transportation. The wireless technology plays the vital role in this a utomation system.
