文档介绍：摘要
本作品是提出一种“无碳”方法,即给定重力势能为5焦耳(取g=10m/s2),质量为1Kg的重块(￠50×65 mm)铅垂下降,落差500±2mm,重块落下后,须被小车承载并同小车一起运动,不允许掉落。带动小车的运行,即给定一重力势能,根据能量转换原理,设计了一种可将该重力势能转化为机械能并用来驱动小车行走的装置。
该自行小车在前行时能够以正弦曲线或余弦曲线轨迹自动避开赛道上设置的障碍物(每间隔1米,放置一个直径为20mm,高为200mm的弹性障碍圆棒)。此模型最大的特点是将重力势能转化为齿轮的转动,进而根据大小齿轮的粘合带动驱动轮和转向轮,从而按照规定的路线完成任务。本文将对无碳小车模型的设计过程,结构功能特点等进行详细的介绍。

Abstract
This work is to propose a "no carbon" method that given for 5 joule (gravitational potential energy take g = 10m/s2), quality as the heavy block (1Kg ￠50 x 65 mm) vertical drop, divide lead 2mm, heavy pieces of 500 +, it must be carrying with car exercise with after fall , it not allowed to fall. Drive the car running, given a gravitational potential energy, according to the principle of energy conversion, design a kind of potential energy that can be transformed into Mechanical energy, the Mechanical energy used to drive the car walks .
The car when traveling can be automatic avoid the barriers with sine curve track or cosine curve track(intervals of 1 meter, placed a 20mm diameter and 200mm high for elasticobstacles round rods). The model biggest characteristics is a potential energy into gear rotation, which according to the gear adhesive rotation that drive the driven wheel and steering wheel, plete the task with the prescribed route .This paper will be detailing introduction
The no carbon car model of the design process and the structure and function characteristics .

第1章引言
“环保在身边之‘无碳生活’”一帖在东楚网黄石新闻网发出后,众多网友纷纷跟帖支招,倡导“无碳生活”。多数网友认为,对社会整体而言,完全“无碳”难以做到,但有意识地减少“碳排放”,却是随时随地可
