An Embedded System Based Low Cost Autonomous Vehicle For Navigation And Obstacle Detection

In this paper, design of a low cost autonomous vehicle based on embedded system for navigation and obstacle detection in unknown environments is presented. The vehicle is equipped with one ultrasonic and three IR sensors for hurdle distance measurement and obstacle detection, a LCD for display frequent information, a GPS receiver for global position information, a GSM modem for changing destination place on run time; all interfaced to a low cost P89V51RD2 microcontroller and a mobile phone to send and get information by the user. The microcontroller processes the information acquired from the sensors and generates vehicle motion commands accordingly. The vehicle is tested with varying Destination places in outdoor environments containing stationary as well as obstacles and is found to reach the set targets successfully.
