机器人擂台赛。利用FPGA（EP2C5T144C8N）作为控制器，控制机器人实现避障、攻击其它机器人，以及清扫擂台。-Robot Challenge Cup. The use of FPGA (EP2C5T144C8N) as a controller to control the robot to achieve obstacle avoidance, attack other robots, as well as cleaning the ring.

此代码为可循迹小车的源码，实现红外遥控小车，以及超声波避障和红外循迹。-To follow tracing cart source code, the code so as to realize the infrared remote control cars, as well as ultrasonic obstacle avoidance and infrared tracking.

代码主要实现小车的红外避障以及超声波测距，进而控制点小车跟随人行走。-The main code of the car infrared obstacle avoidance and ultrasonic ranging, and then control point car to follow people walking.

DE1-SOC实验开发板和Verilog HDL语言的交互式程序作品，选择避障小车作为课程设计题目，并根据选题制定了如下设计需求： 1.能实现基本的避障小车功能，即躲避障碍，变速，计分，计时显示游戏开始、进行和结束画面； 2.能实现人机交互功能，玩家可通过外接键盘或DE1-SOC开发板自带按键和开关操作小车转向； 3.能通过VGA在显示屏中显示，并且能达到5Hz的刷新频率； 4.能实现自定义小车和障碍物皮肤的功能；(DE1-SOC experiment development board
