    四年級狀物作文:神奇的無人機_600字

    2019-07-17 21:09:37

      同學們,你們知道無人機嗎?顧名思義,就是沒有人駕駛的機器。你們相信有這個東西嗎?有,而且用處不是一般的大。

      無人機表面看上去就像我們的遙控飛機。上面有4根細細的螺旋槳。

      我們都知道快遞吧!快遞員們每天都在拼命地送信件,雖然有車子,但一天也送不上幾件。怎么辦呢?

      在這個時候,無人機就有了很大的作用。只要把快遞裝在無人機上。用手機給它定位,讓它起飛。慢慢的,無人機起飛了,一米,兩米,三米。。。。。。無人機離開了地面,它搖搖擺擺地到達了高空。漸漸地,無人機在天空中形成了一個黑點。最后就看不見了。而送快遞的人呢,就坐享其成。不費吹灰之力就送了一個快遞。當然,過不了多久,無人機就會回來。這樣既方便又快捷。

      無人機還是所有攝影愛好者、動物學家的福音!當人們無法到達山峰進行拍攝時,就可以用無人機。在無人機上裝上攝像頭,再安上定位裝置。讓他在山峰周圍錄像。這樣質量既好,又不麻煩。它還能拍到人類無法踏足的冰川、高地等。

      還有一個謎題,你們解得開嗎?動物世界這個節目里近距離拍攝狼、鱷魚、豹子、老虎。。。。。。等兇猛動物的攝影師是誰嗎?哈哈,當然還是無-人-機了!

      在無人機上安攝像頭就行了。如果動物要去攻擊它,它就靈活飛向空中。這樣,拍起來就方便多了。

      如果按照這個原理,我國就很可能生產出無人飛機、無人出租車、無人火車、無人駕駛輕軌。要真是這樣,生活該是多么有趣,多么美好。。。。。。

      這種無人駕駛交通工具能不能實現,只能問我們人類自己。我相信,在我們的學習下,不久的將來它一定會實現。
