  • 我想發明行走器

      今天,我正在校園散步,看見一位白叟柱著拐仗正在大上費勁地走。紛歧會兒,幾個不到一歲的小孩正在大上左搖左擺地走著。

      我想,正在大上如許走多啊!若是有一種行走器,能夠升縮,有很多能夠勾當的“關節”,并且有很多背帶,能夠綁正在身前或死后。它的每個關節都連著一個頭盔,阿誰頭盔上有良多器,能夠領受到大腦傳來的信號,正在通過電源傳送給各個“關節”,如許人就能夠不費吹灰之力地走了。

      我找來一些材料,起首將鐵棍剪成圓柱形,將一大一小的鋼球放正在鐵棍的地方,每個關節都如許做,行走器完成后墊一層海綿,若是為白叟設想,能夠正在背后拆上按摩器,如許就愈加舒服了。我現正在設想的雛型不敷完滿,并且不克不及行走。
