FPGA-Based Car-Like Robot Path Follower with Obstacle Avoidance

Abstract

This project is about the design and implementation of an System on Programmable Chip (SoPC) based automated path following with obstacle avoidance using infrared sensors and ultrasonic sensor.The Line follower robot is a mobile machine that can detect and follow the line drawn on the floor using infrared sensors which are installed under the robot. The path is predefined as a black line on a white surface with a high contrasted color.This robot is provided with ultrasonic sensor to avoid an obstacle either from the right or the and it will stop if an obstacle is detected on the path or if the path is ended.The digital controller is designed and implemented using both the integrated circuits and the Field Programmable Gate Array (FPGA).
