在写作文时，我们可以采用排比和对比的修辞手法，通过多读多写，我们可以不断提高作文的水平，下面是小编为您分享的我想发明笔作文7篇，感谢您的参阅。
五点半下班的爸爸，七点了还没有回到家，坐在饭桌旁的我，看着香喷喷，热乎乎的饭菜上的“雾”，而我的思想却开始游离。现在科学家发明了这么多的高科技，有直升机啦，有无人汽车啦，有钻地车啦，怎么就没人发明一种可以让爸爸妈妈陪孩子多一些时间的汽车呢？所以我要发明一种劲爆多功能汽车，让高科技给我们带来方便与幸福。
首先，他得是三栖的。在地上它是时速20～1000公里每时的超音速汽车，适合各种年龄的飙车手，车身是用铬（最坚固的金属）做的，钻石做的，它是全电脑控制的，又安全又准确无误。在水里，它就变成潜水艇，排气管和车轮变成螺旋桨，假期里，大人可以带孩子去探索海底探索大自然的奥秘；在空中，它就是直升机，车顶有一根定位杆，上面有电磁，机翼从车底弹出，电磁会把它牢牢地吸住，把它们安装上去，上下会有两块夹板把它夹住，电钻自动安装上螺丝。堵车时它就能直接飞过去。
它可不止有三栖这么简单，最劲爆的是，它还可以无限制能源充电和压缩。不论白天黑夜，不论工作与非工作都会不间断地充电，因为它顶上有一块无线能源电极板。在它熄火后，它会变成粉笔盒大小的迷你车模，方便携带又不用排队找车位了。
这就是我要发明的劲爆多功能汽车，让辛苦上班了一天的爸爸妈妈既不会饿肚子，又可以多一些时间陪孩子。让高科技为我们带来方便和幸福吧！
我想发明的机器人有许多功能，它可以植树造林、吸收废气放出清新空气、把垃圾变成电等......
机器人的第一个功能就是植树造林。机器人会去大沙漠种上数不清的绿树绿草。一但这样，就是大沙漠也会变成绿洲;机器人的第二个功能就是把废气吸收到体内，放出清新空气。这样一来，世界的废气就几乎没有了，而清新空气会非常多;机器人的第三个功能就是用它的“吸收垃圾器”把垃圾吸收到自己的身体里,再转化成电，造福人类;机机器人的第四个功能就是去山上挖宝藏，送给穷人，一但这样，穷人就不会没钱用了;机器人的第五个功能就是进入人类的身体里，把细菌消灭，这样一来，人类的身体就会很健康了;机器人的第六个功能就是当你爸爸妈妈不在的时候，给你当全自动保姆;机器人的第七个功能就是......
这就是我做的机器人,完美吧!如果叫小朋友你来做一个机器人,你会怎么做呢?
我想发明一种保洁机器人，这种保洁机器人可不是普通的，它不仅会清扫，还会把清扫出来的一些东西变成其他东西。
保洁机器人可以用它的红外线扫描地上有没有垃圾，就连细菌也能扫描出来。也许你会想，细菌怎么清扫呢？不用担心，它可以把细菌变成一棵棵茂密的大树、一朵朵飘香的花，或者是清澈见底的小河。而且，它还可以用吸尘器把汽车尾气全部吸进去，再把这些气变成电，它就再也不用充电了。
保洁机器人还可以清洁河面呢！我这么说，你当然不信。那我就给你详细说一下吧：它要先把河水吸干，再用吸尘器把所有的垃圾吸进去，然后把这些垃圾变成干净的水，变成鱼，变成蜻蜓，变成青蛙、荷叶、荷花。它还可以像啄木鸟一样给大树治病，不只是大树，所有植物的病它都可以治，它也可以给动物治病。
怎么样，我发明的机器人厉害吧？
如果没有了创新思维人类将走回原始时代，我看到街上每到高峰期，路上汽车就会堵得水泄不通，我想到了如果有可以在路上行驶又可以在空中飞的汽车，我感觉穿衣服太麻烦，我想到了会自动收缩的衣服；我看到人们做饭时间太长很麻烦，还会被油浅到，我想到了会自己做饭的机器，今天，我想发明机器人保姆。
因为现在很多家庭的父母都很忙，没有时间照顾孩子，所以我想发明一种机器人保姆。这和保姆的样子和真正的人很像，每到早上，它会叫你起床，如果你不听话，它就会对着你唱起大声的《忐忑》，然后把你扶起来，给你刷牙洗脸，再给你做一份营养早餐，让你身体棒棒的，吃嘛嘛香。他还会变成汽车，自动接送你。你做作业的时候，它会教你做你不会做的题，然后守着你，不让你贪玩。如果你遇到了坏人，它会火速来到你身边赶走坏人。如果你累了，它会给你按摩。你自睡觉的时候，它会给你唱《摇篮曲》，让你更快入睡。每当周末，它教你做完作业，就会陪你去公园玩，去大吃一顿，让你感觉到家的温暖，15年过去了；我发明出了这种机器人。早上，我听见有人在喊：“起床了！”起床了！再不起床我要唱忐忑了！我一听说：“烦死了！”啊——哦！啊——哦！天啊，我一看时间，哇！差点迟到，我便上班去了。
这就是我相恨明的机器人保姆，从现在开始，我要多读一些关于机器人的书，让这种机器人保姆走进每一个家庭。
when i was a child, i was always dreaming of what i could become when i grew up. become a singer? become a painter? become an actor? these are some glamorous professions, and what i want to be the most is an inventor.
although the inventor is a behind-the-scenes worker, he can make a great contribution to human development. it can make peoples lives less tired and make people happier every day.
if i were an inventor, i would invent many things that would be convenient for people to live on. start with peoples housing starts! if i were an inventor, i would invent a very advanced door. the shape of this door is not different from the ordinary one, but it has many functions. first of all, when the noise coming from the corridor, the door can be according to the masters voice as he opened the door ahead of time, when the owner came to the door it say: "master, welcome home!" then the door closes. the advantage of this design is that the owners no longer have to go out with keys. second, if there is a bad guy to destroy the door, the door have a security alarm system, can let the neighbors know there is a thief, the thief will soon be away. and the door will also send the information to the owners mobile phone for the first time, telling the host that there is a bad guy and need to deal with it as soon as possible. finally, the door has the function of weather forecasting. at seven o clock in the morning, it will report on time and report the weather and the situation of the day. if the weather forecast says its going to rain, the door will offer an umbrella before its owner goes out, and if its a big summer it will also offer a sunblock and sunscreen. the invention guarantees home safety, improves living standards and makes peoples lives more comfortable.
if i were an inventor, i wanted to invent a medicine that would delay peoples life slightly. because i know that it is impossible to live forever, and if you can live forever, there will be more and more people in the world. a slight delay is the ability to make a persons life a little longer. the invention is mainly used for the immediate death of the hospital, but to the people who want to see the last of their loved ones. or people who are in a car accident or other sudden death. because of this invention, they can be able to see the last part of their family, leaving them with the words they want to say, without regret.
if i were an inventor, i would invent an emotional robot. scientists say robots are mechanical, unemotional and cant understand what people really need. and im going to invent this robot, which has its own personality, apart from being able to do the housework, the laundry, the cooking. owners can choose robots with different personalities.
there are gentle, considerate, or tyrants. the charm value of the robot can be acquired by itself. at that time, the robot is more than just a machine, it can be your family, your friends, more like your child. hes hungry and needs you to feed him. when you are sad it will hug you, stand beside you and comfort you and tell you jokes. when youre nervous, it encourages you and tells you its ok. when you are happy, it will give you all kinds of celebrations, standing next to you and dancing, more than you are happy. but the baby robot also dies, for example, when it dies of starvation, or parts that are too long and die. but you can rest assured that the life of the robot baby is usually a hundred years old, enough to accompany you forever.
if i am the inventor, i would also like to invent a lot of things to benefit mankind, im not in order to let everyone thank me, let me earn a lot of money, but in order to let people all over the world have a safe, happy, happy, carefree, so i am very satisfied. i would like to be an inventor. for this dream, i must study hard and go to a good university in the future. i can get rid of the word "if" and realize my dream.
我想发明一款神奇的鞋子，它表面上看起来和普通的鞋子没什么两样，但我要让它会变款式，自动调节鞋码大小，还能飞行。
现在的鞋子有皮鞋、拖鞋、帆布鞋、运动鞋，换来换去很不方便。所以，我想发明的鞋子，会根据需要自动变换款式，还具有自动调节鞋码大小的功能。以后爸爸妈妈给我买鞋的时候，就不用担心把鞋买大或买小了。而且在学校它可以变换成运动鞋或帆布鞋；回到家它也可以变成拖鞋或棉鞋；溜冰时，它还可以变成溜冰鞋最重要的是，我不用因为长身体穿不下以前的鞋而经常换鞋了。这样，我们每个人只需要好好拥有这样一双鞋就够了，岂不是可以节约很多资源？
我想发明的鞋子还具有飞行功能，它就像风火轮似的。如果你想去空中观赏美景，那么只需穿上它，你就能像鸟儿一样在空中飞翔。如若遇到紧急事件，它还可以发挥逃生的作用。比如突发火灾时，有了这样一双鞋，就不需要等消防员的救援，自己可以直接逃离火场了。
这就是我想发明的鞋子，它是不是既神奇又实用呢？
我想发明一个医疗机器人，它长得胖胖的，是充气式的，不需要时放气后压缩今年小小的工具箱，方便携带。
它的功能可多了!它可以帮助妈妈打扫卫生、给花草树木浇水、照顾小动物、帮助盲人过马路、哄人开心……
它最大的功能就是给人看病，它不但能够治愈身体疾病更能治愈心理疾病。它拥有无比强大的诊断等级，在胸口的显示屏上有表情诊断等级，可以真实显示病人的心理状况，针对病情帮助人类恢复积极向上的快乐心情。如果你是它的病人，它会对你说：“乖，会好起来哒。”还有可敬的医护态度一直陪伴你左右，直到你痊愈。
它能守护一切生命，可以照顾动物，给它们安全感。
它的一切能量来源于电，当它电量不足时就会像喝醉一样，走路摇摇摆摆，说话断断续续。这时你可以把废电池给它吃，它就可以把废电池转化成它自己的能量。
当机器人出现问题时，它可以自我修复。
这就是我想发明的机器人，你喜欢它吗？
