先说真空泵的问题\r\n</br>\r\n</br>\r\n物色了半天某宝后，选择了一款觉得还行的。\r\n![qq 20150324185811](https://cloud.githubusercontent.com/assets/10279946/6800335/65e26050-d258-11e4-9214-2c6073389921.png)\r\n![qq

这样的设计行不行\r\n![img_1760](https://cloud.githubusercontent.com/assets/10279946/6800749/5e854bf2-d25c-11e4-915f-b4f54468cc84.JPG)\r\n## 三个？\r\n![img_1761](https://cloud.githubusercontent.com/assets/10279946/6800762/79b285c0-d25c-11e4-9379-7b274f724a31.JPG)\r\n甚至这样？\r\n由于经过计算吸起来工件很可能是轻而易举的一件事（考虑到漏气）。那能不能做一个这样的装置。\r\n到时候甚至直接插到木块堆中吸起来一批。\r\n![img_1762](https://cloud.githubusercontent.com/assets/10279946/6800781/a90aee0c-d25c-11e4-81a0-63f341d13d31.JPG)\r\n\r\n甚至如果两个操作员的话，可以弄两个球，DOUBLE拿。\r\n如果吸头和真空泵足够多的话好处也比较明显，可以用比较简单的方式拿较多的木块。\r\n当然球上的吸头位置需要经过设计不能使得吸上来的木块互相打架，个人感觉可以通过控制吸头的长度来控制。经过计算如果是5CM长的吸头加上5CM的球就可以拿很多的木块。\r\n后来经过相如男神的点播，可以设计成环形的。\r\n![img_1763](https://cloud.githubusercontent.com/assets/10279946/6801122/f95bc4c8-d25f-11e4-9312-9f460d0f4de0.JPG)\r\n这样可以减少设计上和操作上的难度。\r\n当然纯属脑洞。。\r\n\r\n\r\n\r\n\r\n</br>\r\n</br>\r\n__--------------------------------------------我是萌萌的分割线它哥-----------------------------------------------------------__\r\n</br>\r\n</br>\r\n当然这种抓木块的方式缺点也很明显，害怕对方肉搏撞击。但也不排除做一个灵活的机械臂和灵活的小车来躲避的可能性。（最后的那个球球纯属脑洞，开心就好）\r\n\r\n有个遗留问题我没法解决：\r\n如果我将真空泵放在小车车身上，然后通过长长的橡胶管连接到车头的吸头上，对吸力是否会产生影响？个人支持没影响的观点（CITE：吸尘器），但是无法证明。\r\n\r\n</br>\r\n</br>\r\n__--------------------------------------------第一次更新3.24
