柱子P1、P2的位置是可以随意摆放的,机器人R沿黑线方向行走。利用6号和9号声纳来测距离(这两个声纳的测量角度比较大,可以很好号的实现设计要求),6号声纳测机器人与P1的距离d1,9号测机器人与P2的距离d2。当机器人行走到某处时,两个声纳分别测到的距离差d1-d2小于20mm,并且d1、d2都小于600mm时,则判断为此时机器人行走到了P1与P2的中间,机器人转90°,沿两柱子的中心线继续向前走。-Columns P1, P2 position can be arbitrarily place

这个程序的关键是表示蛇的图形以及蛇的移动。用一个小星形表示蛇的一节身体,身体每长一节,增加一个星形块,蛇头用两节表示。移动时必须从蛇头开始,所以蛇不能向相反方向移动,也就是蛇尾不能改作蛇头。如果不按任何键,蛇自行在当前方向上前移,当游戏者按了有效的方向键后,蛇头朝着指定的方向移动,一步移动一节身体,所以当按了有效的方向键后,先确定蛇头的位置,然后蛇身体随着蛇头移动,图形的实现是从蛇头的新位置开始画出蛇,这时由于没有清屏的原因,原来蛇的位置和新蛇的位置差一个单位,所以看起来蛇会多一节身体,所以将蛇

RAKE的概念是由R.Price和P.E.Green在1958年的《多径信道中的一种通信技术》一文中提出来的。Rake的中文意思是:耙子,表明瑞克接收的过程相当于用一个钉耙将各个多径信号“耙”出来,然后加以收集。通常接收的多径信号时延差很小且是随机的,叠加后的多径信号一般很难分离,而只有特定设计的信号才可以进行分离,这种信号即扩频信号。分离的手段是相关接收-RAKE concept put forward in 1958 " a multipath channel communicati
