Looking forward to, looking forward to, choose of Dongguan city small academician began 2021! The activity collected many divisions to achieve that day fan, want to compare relative superiority or inferiority. I assemble process designing a car attends square round of car challenge.
盼望着，盼望着，2021年东莞市小院士选拔开始啦！当天活动聚集了不少科创迷，都想一比高下。我组装编程了一辆小车参加方轮车挑战赛。
Square annulus the car is the special vehicle that forms by quadrate wheel, cannot go up smoothly in general and planar road sail, must write a composition in special design ability of travel of wave landform orbit is smooth, the arc length of wave wants to wait with the appearance side quadrate wheel, otherwise cannot smooth travel.
方轮车是由方形轮子组成的特殊车辆，不能平稳地在一般平面道路上行驶，必须在特殊设计的波浪地形轨道行驶才能平稳，波浪的弧长要与方形轮子的边长相等，不然就无法平稳行驶。
My square annulus is cycle racing how do? Use the building blocks in Microbit hardware suit first the batholith of mosaic car, install mount a horse to amount to in the place of 4 horn, by Microbit patulous edition is joined all motor add wheel of upper part form, reoccupy another advocate board installation is in Microbit is exclusive make above handle their couplet net, write a program to form a remote control square round of car, this is the secret weapon that I join a challenge.
我的方轮赛车是怎么做的呢？先用microbit硬件套装里的积木拼成车的底盘，在四个角的地方都安上马达，由microbit扩展版连接所有马达加上方形轮子，再用另一个主板安装在microbit专属手柄上面使它们联网，编写程序形成一个遥控方轮车，这就是我参加挑战赛的秘密武器。
"The match begins! " make fall as of the commissioner, everybody is sent on respective " car god " , my challenge group rival people somebody uses EV3 to make an appearance very of cruel square round of car, this square round of car cannot remote control, can go persistently forth only. We are in same a challenge on orbit over- , although his appearance very cruel, but the action is not quite quick, my racing bicycle is OK remote control, cabinet and agile, action freely, "Run run run... change change change... " developed terminus, show itself successfully finally.
“比赛开始！”随着评委的一声令下，大家都派上各自的“车神”，我的挑战小组对手们有人用EV3做出一台形状很酷的方轮车，这台方轮车不能遥控，只能一个劲地往前走。我们在同一个轨道上挑战过，虽然他的外形很酷，但行动不够敏捷，我的赛车可以遥控，小巧灵活，行动自如，“跑跑跑……变变变……”冲到了终点，最后成功脱颖而出。
Next, it is the racing bicycle with another adversary one definitely relative superiority or inferiority. The racing bicycle of adversary accepts electrify pool travel directly, motive force is very powerful, I can hear electric machinery to turn at full speed " buzz... " sound, but as the match intense undertake, I heard the irregular voice beyond electric machinery, because follow orbital comfortable it is good without the design to match a gender, car and orbital collision voice are stronger and stronger, travel arrives after the half whole racing bicycle flies off orbit, "Whiz " , become the car flies in sky. And my racing bicycle is reliable, before one direction... , I was hanged in the big stone in the heart to fall down eventually then, I won this match to win again.
接下来，是与另外一个对手的赛车一决高下了。对手的赛车是直接接上电池行驶的，动力很强，我都能听到电机飞速转动的“嗡嗡……”声音，但随着比赛的激烈进行，我听到了电机以外的不规则声音，由于跟轨道的适配性没有设计好，车辆与轨道的碰撞声越来越强烈，行驶到一半以后整个赛车飞出轨道，“嗖”的一声，变成空中飞车了。而我的赛车稳稳当当，一路向前……，我那悬在心里的大石头终于落了下来，这场比赛我又赢得了胜利。
My remote control racing bicycle, because the balance sex of the design is very good, after enough power matchs, still can go up in planar road travel, look, it runs the model that rise more resembling is 4 sufficient robots, although the meeting is remittent the ground is bumpy, but it can cross the fraise such as step easily like quadruped, this can be the job that average racing car cannot finish, the accord that my work also got commissioner teacher reputably.
我的遥控赛车，因为设计的平衡性很好，有足够的动力搭配后，还可以在平面道路上行驶，瞧，它运行起来的样子更像是四足机器人，虽然会上上下下地颠簸，但它能像四足动物一样轻松越过台阶等障碍物，这可是普通赛车无法完成的任务，我的作品也得到了评委老师的一致好评。
After the challenge, commissioner teacher chooses me to become " dug result reports " compere, I and father had done speech PPT together, what telling first is square round of car, still introduced a principle of round of car next, we report very racily, the form that uses an old practice is told about square round of car, we ended to be full of the challenge dug result of gout to share so. We ended to be full of the challenge dug result of gout to share so..
挑战赛后，评委老师选我当“探究心得报告”的主持人，我与爸爸一起做好了演讲PPT，先讲了什么是方轮车，然后还介绍了方轮车的原理，我们报告得很生动，用故事的形式讲述方轮车，我们就这样结束了充满趣味的挑战赛探究心得分享。“
Now, I will announce this second activity joins list: ... Huang Yunlin... " when the name that becomes me is read, that becomes very happy in the heart momently. I must cherish this god-given honor well, this is the honor that more or less need course tries hard to just can be obtained!
现在，我来宣布本次活动入名单：……黄云麟……”当我的名字被读到时，那一刻心里乐开了花。我一定要好好珍惜这难得的荣誉，这是需要经过多少努力才能获得的荣誉啊！
Good unforgettable square round of car challenge!
好一次难忘的方轮车挑战赛！
