The Design and Implementation of FPGA-Based Ultrasonic Obstacle Avoidance Car

Abstract

Along with social progress and scientific development, there is increasing demand for smart devices. In this paper, the design of ultrasonic obstacle avoidance car can be widely used in intelligent household, intelligent robots and other sports-related equipment. This paper will use Verilog HDL language to implement combining FPGA chip with ultrasonic ranging module and control motor drive to achieve the car's automatic obstacle avoidance function. The car uses the maze left hand rule for automatic obstacle avoidance, enable it to adapt to the complex working environment. Based on the FPGA chip's high reliability, good expansibility, easy to transplant and the precise ultrasonic measurement, obstacle avoidance car will has good market prospects because of its high degree of flexibility, accuracy, real-time.
